Advancement in Computer Hardware

Advancement in Computer Hardware

Author: saad shamim

5 years ago we gathered around and marveled at the little specs moving at our commands, doing not much – except moving off course, we called these things games. Today the hardware in computers and other devices has changed significantly; we went from having a "spacious" 1mb hard drive to 250 GB of space. The graphics have also taken a giant leap for our computers, no longer are we confined to little dots but our 256mb graphic cards allow us to explore a virtual world in 3d. The sound has also changed from 4bit to 32 and pretty soon 64bit; we went from beeps to actually words. Finally the speed of our beloved computers has also increased from mere kilobytes to gigabytes of rams. In such a short period of time we went from what we used to call "advanced" technology to today's much superior devices. So if you guys are like I am, there is one question that strikes our mind, what's next? Well I would love to say that we will be able to put on our virtual glasses that will allow us to explore the virtual world as if we were in it, but this is not likely, sorry guys; however, these sorts of glasses are being constructed but its unlikely they will come out any time soon. What we can expect to see is an improvement in our Text-to-speech and vise versa programs after the 64bit sound card is released allowing the computer to understand our voices much clearly, also we should soon be seeing more "dept" in our computer as you may know that the most our computers can run on 32bit resolution, it is expected that Microsoft is like to bring out a 64bit resolution with there next version of windows. Also the speed and graphics are to increase a lot more, already some games look as they are almost real, and soon they will look real. I am not certain exactly what marvel the computer hardware's will hold in the future, but one thing is certain it will be something to forward too, and once again the next generation will be mocking the so called advanced technology we have today.

How to Send a Text Message from Your Computer for Free

How to Send a Text Message from Your Computer for Free

Author: Robert Bell

Text messages are typically sent with the use of mobile phones. The first sets of mobile phones allow users to send messages that consist only of 160 characters. Spaces are counted as well. As years pass by, mobile phone manufacturers increased the number of characters that can be inputted in the message editor. Now, you can create a text message that consists of more than 1,000 characters. But, the innovation in text messaging didn’t stop there. It has also invaded the world of internet as people are now allowed to send text messages from their computer to mobile phones without any charges.

Do you want to know how to send a text message from your computer to a mobile phone for free? Here are the things that you need to do:

1. Find a website that offers this kind of service. There are many free text messaging sites so it won’t be difficult for you to find one. Some of them have their own text editors included in their website, and some of them would ask you to install a text messaging software. You must be aware that some free text messaging websites have limited number of text messages you can send within a day. If you want, you can sign up to all these websites, and use them as they don’t have strict terms and conditions. Instant messaging softwares, as well as free email service websites also offers free text messaging.

2. Check if the text messaging website can really send text messages to any kind of mobile phone. You can try sending text messages to your friends numbers and ask them if they received a text from you.

All free text messaging websites shares the same procedure on how to send a text message from your computer for free. First is to type your message on the text editor. Free text messaging websites normally have this empty box on their home page that looks like the standard message editor of a mobile phone. You can start typing your message there. Then, if you want to express your emotions on your message, you can select the appropriate emoticon which is provided in the text editor. Now, most free text messaging websites only allow you to type at least 160 characters so make sure that you have typed-in the important message that you need to send. After typing your message, type in the recipient’s number. Finally, click the send button or press enter.

If you will be using a text messaging software, you may be able to receive the reply of your recipient. However, they will be charged for every reply they make. The fee is much higher than the standard rate for text messaging, so expect to receive a reply on your mobile phone.Jeff Blackwood writes articles about how to register a dll file and how to uninstall windows live messenger.

Every experience you've had, every person you've met even there names almost all books you have read till date. Now you must be thinking if this is the case than why don't I remember everything from my past? Well look at it this way what if you have files scattered all over your desk and you are looking for a specific file. You would probably have to search for it going through all other files and you may or may not find it.

Same applies to your brain and memory. Everything which is fed into your brain is scattered, it's not organized yet.

Is it a sofa, television, door, fan, chairs or any other sort of thing? Now close your eyes and try to have a picture of your room in your mind. See all the things such a sofa, the television and so on. Now come back to the list of things you want to memorize. For example you want to memorize the history dates. American Independence Day is on 4th of July. You can simply relate this to something in your room. For example think of a guy sitting on your sofa with American flag in his hand watching channel 4 on the TV sitting with Julie.

Now this image is very easy to remember and you can track it back to the guy holding the American flag as the Independence Day, watching channel 4 as 4th and sitting next to Julie as July. In the similar manner you can develop your own picture relations and your own stories.

Ram Make A Computer Powerful

Ram Make A Computer Powerful

Author: JAIPREETSINGH

The functioning of the RAM, or Random Access Memory, in a computer is of immense importance. The function of the RAM is mainly storage capacity, as all programs, operating systems, applications and software must be loaded onto the Random Access Memory before they are used. All computer functions rely on the capacity of the RAM. The name of the entity itself, Random Access Memory, shows the various functions and the various aspects with which it is related. The name explains that all of the things loaded on to the memory can be randomly accessed. Without loading things onto the memory, they cannot be accessed on the computer. Without the RAM, there is nothing that you can do on the computer. A computer without RAM is worth nothing. Nowadays, there are numerous types of RAM that are used in a computer to make it run and work fast. These different types of RAM are being used based on the importance and urgency of a particular task in the computer. The varieties of RAM that are available are SIMM, SODIMM, DIMM, DRAM, FPM, RDRAM-RIMM, BEDO, DDR SDRAM, and EDO. After the invention of these varieties of RAM, the working of RAM has become even faster than before. The FPM is commonly known as the Fast Page Mode and is used to access the data located in the same row quickly. Another memory is called SIMM, which is known as the Single In-line Memory Modules. This is used for the same purpose for which the BEDO, DRAM or the EDO are used. The general functions of all of these types of RAM mentioned are basically the same because they ultimately support all computer functions. However, the look of the SIMM is a bit different from the others as there are several chips in this kind of RAM. The DRAM is known as the Dynamic Access Memory and this is the most familiar type of RAM among all those are present and available. But this is not as powerful as some of the other ones are. The DRAM can hold the memory for a short span of time, while some others can support memory functions for a longer time span. Also, these have to be refreshed constantly or else there is no assurance that the memory to last long. The RAM capacity is measured in bytes and based on this amount only the capacity of the computer is determined. Hence it has also been established that in the absence of the working of RAM, it would have never been possible for a computer to run and to function well.

PC Runs Slow and Crashes? Trick to Make Your Computer Run Like New Again

PC Runs Slow and Crashes? Trick to Make Your Computer Run Like New Again

Author: Omar Pugh

"Take good care of your PC, and it will take good care of you."


Computers are great machines when they are running smoothly and effectively... but as soon as they start to run slowly or with errors, it's a different story altogether. Having a computer that crashes and runs slow is a big problem, but there's actually an easy way to fix it. Here's what you need to do to make your system run like it did when it was new.

The reason why many computers run slowly is not because of the hardware of your system or even the amount of programs you have installed on it,the biggest cause of an unstable PC is the registry of Windows. The registry is simply a database which stores information and settings for your computer, allowing it to recall such details as your email address, desktop wallpaper and even your most visited web pages. The registry is one of the main components of your computer and is vital for making your system run quickly & smoothly. However, it's also a double-edged sword, which can constantly make your PC run slowly and crash.



Think Outside the Box

Cleaning the Prefetch Directory



WindowsXP has a new feature called Prefetch. This keeps a shortcut to recently used programs.

However it can fill up with old and obsolete programs.



To clean this periodically go to:



Star / Run / Prefetch

Press Ctrl-A to highlight all the shorcuts

Delete them



Not Displaying Logon, Logoff, Startup and Shutdown Status Messages



To turn these off:



Start Regedit

Go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionpoliciessystem

If it is not already there, create a DWORD value named DisableStatusMessages

Give it a value of 1



---------------------------

If you want to clear the page file on each shutdown:



Start Regedit

Go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementClearPageFileAtShutdown

Set the value to 1



---------------------------

The program is called BootVis



Uncompress the file.

Run BOOTVIS.EXE

For a starting point, run Trace / Next Boot + Driver Delays

This will reboot your computer and provide a benchmark

After the reboot, BootVis will take a minute or two to show graphs of your system startup.

Note how much time it takes for your system to load (click on the red vertical line)

Then run Trace / Optimize System

Note how much the time has decreased

Mine went from approximately 33 to 25 seconds.

Increasing Graphics Performance



By default, WindowsXP turns on a lot of shadows, fades, slides etc to menu items.

Most simply slow down their display.



To turn these off selectively:



Right click on the My Computer icon

Select Properties

Click on the Advanced tab

Under Performance, click on the Settings button

To turn them all of, select Adjust for best performance

My preference is to leave them all off except for Show shadows under mouse pointer and Show window contents while dragging

4096 - 32megs of memory or less

8192 - 32+ megs of memory

16384 - 64+ megs of memory

32768 - 128+ megs of memory

65536 - 256+ megs of memory




Know your rights

Windows XP comes bundled with Windows Media Player 8.0. While Media Player plays just about any digital media file format-it supports 35, including MP3, it records music only in the Windows Media Audio, or WMA, format. The reason? Content protection.

When recording, or ripping, music from CDs, Media Player allows you to make protected recordings so that no one will be able to copy the recording from one computer to another. You can turn copy protection on or off on the Copy Music tab by checking or unchecking the box that says Protect Content.

Protect your identity

Like many other audio players, Windows Media Player rushes out to the Internet to find information for you when you play a CD. Some of this information, such as song titles and album art, is useful, but Media Player also identifies your copy of Media Player to the site where it's getting data. Why? According to the help file, "The server uses this unique identifier to monitor your connection. By monitoring your connection, the server can make adjustments to increase the playback quality and to alert you about events that occur when receiving streams over the Internet."

If you're disturbed by this exchange of information, here's how to stop it. In Windows Media Player, click Tools > Options and go to the Player tab. Notice the option that says "Allow Internet sites to uniquely identify your player?" Turn it off.

Reduce Temporary Internet File Space

The temporary internet files clutter your hard drive with copies of each page visited. These can build up over time and take up disk space. Even more bothersome is that instead of getting new pages each time IE often takes the page out the temp internet files. This can be a problem if you are viewing a website that is updated all the time. If you are on a slow connection such as a 56K or lower then this can be good but if you are on a fast broadband connection, like me, then you can get away with decreasing the size of your temp internet files to just one meg without any performance decrease

Turn Off System Recovery

Right click on My Computer and choose Properties. Click on the System Restore tab and check the box Turn off System Restore. (This will increase Windows performance & save disk space)




SO THIS WAS THE TOTAL FASTER MAKER PROCESS TO SPEED UP COMPUTERS AND
DONT FORGET TO INSTALL ANY GOOD REGISTERY CLEANER.

Common Causes of Slow Computers and What You Can Do About Them

Common Causes of Slow Computers and What You Can Do About Them

Author: Debt Free

It’s a common source of frustration for too many people; the slow computer. In many cases the thing will freeze up entirely, leaving you stranded in an electronic limbo. Thankfully there are some common causes for the freezing and slowdowns afflicting many computers and their frazzled owners. Here are some of the most common causes and some ways you can do about them.

Slow computer cause #1 - Insufficient memory (RAM). A lack of RAM will affect your computer the most when you are running multiple applications simultaneously. That’s a fairly common occurrence these days. Think about how many times you run multiple apps at the same time. It’s not tough. In fact, you’re probably doing it now. In fact, it would be pretty difficult to run one at a time for most people.

Now that many computers ship with 1GB of memory or greater you may think that having computers slow down due to insufficient memory would be a thing of the past, but thanks to Microsoft’s new Vista OS, we may actually see it continue or even increase. It looks like Vista has a prodigious appetite for RAM. For all but Vista Home Basic edition, Microsoft recommends at least 1GB, but you’d do well to double that, and bring 2GB to the party.

Slow computer cause #2 â€" Spyware and adware These sometimes malicious applications get on your PCs in all different ways, from legitimate applications installing them for tracking marketing data, to key loggers and other programs used to steal your passwords, account numbers, and other sensitive data. The bottom line is, the stuff is dangerous and slows down your computer. Even the stuff that’s not malicious can easily be a culprit. It takes up valuable hard drive space and eats up clock cycles you could use for other things.

Slow computer cause #3 â€" Viruses and worms Hopefully you have a good antivirus application that’s updated regularly. That will nip most virus problems in the bud, but it’s still possible to get a virus. In fact, even if take all standard precautions, such as not opening unrecognized email or attachments, etc., you could still get one. If you’re lucky, these malicious applications will only slow you machine down, in many cases, it will do that and much more, such as data corruption or deletion.

Slow computer cause #4 Too much stuff going on in there. You may just plain be asking too much of the old girl, or you may have to restructure your start menu so apps you don’t use al the time aren’t started automatically. That can not only impact your computer’s speed as you’re using it, but dramatically lengthen its startup time.

Slow computer cause #5 â€" Registry errors These are one of the most common causes of slowdowns and crashes experienced by most users. Registry problems can also make your computer take a longer time to start up. The registry is where, on a Windows machine, all the important settings and other information is stored that the computer and the applications use to run. It’s actually a database that’s created by the system itself.

As you constantly add and remove programs, it creates problems in the registry. When most applications are installed they put new entries in the registry that’s used to run the application. One of the most common problems occurs when entries in the database called registry keys are missing or corrupted. These keys contain information that’s sorted as either computer or user specific. This enables the machine to support multiple users and applications simultaneously, so it’s easy to see how important the registry is. Incorrectly uninstalling an application is one of the most common ways a registry entry gets corrupted or deleted.

Thankfully it’s not too difficult to find and repair Windows registry problems. There are applications available that will do it for you, or you can try to do it yourself if you’re especially well versed in Windows. The software route is usually the preferred route. The applications are pretty sophisticated and easy to use. Typically you just install them and let them run. They'll take care of the problems for you. Do it every month or so to keep your registry in good shape and your computer running smoothly.

These common causes of a slow computer are, in most cases, easily fixed, either through a little tweaking with your machine, or with a specific application designed to solve the problem.

For how you can easily solve your slow computer problems, go to the fix a slow computer guide and see how fast you can put a stop to your problems.

Tips On How to Get the Ideal Previously Owned Laptop Computer System for the Amount of Money You Pay

Tips On How to Get the Ideal Previously Owned Laptop Computer System for the Amount of Money You Pay

Author: MHelphrey

There are lots of different ways to locate a adequate laptop computer for your own or another. Ä°t is possible to order a fresh laptop computer straight through the retailer or company or else you can find a second hand and restored laptop computer belonging to the comparable outlets. Way too many people today believe that typically the refurbished laptops usually are Second rate and therefore are not going to amount to a superior quality working unit much like the brand-new types. Frankly the refurbished laptops tend to be exactly the same when compared with the newest ones.

A computer system that is refurbished simply signifies that the entire hardware, software, as well as computer specs are actually reconditioned back to the way they were when they were new. Which means the reconditioned computer is basically a completely new laptop computer. In reality, that is why you will notice vendors provide whole warranties and guarantees on restored computers, simply because operating wise, they are just as good as brand-new.

Regardless if it's refurbished back to completely new, laptop companies can’t price the restored laptops for the exact same price as the new ones, they simply would not easily sell. Therefore, when in the market for a good mobile computer unit, it again just makes sense to move after a restored one in which delivers all the accessories and features you want. Commonly you will see these at loads of dollars under the new in the store selling price.

You'll find these enormously lowered low-price laptop computers through the actual manufacturers themselves or even via one of their countless outlet retail sellers. Going through the same supplier to get a refurbished laptop should virtually guarantee you that you are going to receive a top quality machine for the price you pay. Purchasing beyond the actual brand is not going to normally assure that you are likely to buy a superior mobile computer.

If you end up seeking a restored computer system on the net, be aware that lots of people advertising such computing devices mistake refurbished to suggest used. A used mobile computer, although still a good purchase in most cases, might not exactly signify the laptop have been refurbished back to standard qualities. It could mean that what you see is actually exactly what you get, in which example might be a broken or perhaps nonworking machine. Some other occasions it might be as basic as needing the right battery power or maybe replacing particular laptop power adapters. If this describes the actual case, simply do an easy look up AC adapters for laptops and discover one that appropriately matches to the second-hand mobile computing device.

A previously owned computer which has definitely not been overhauled with the correct specifications mustn't be a higher priced purchase you will want to make. In the event that you are going to purchase a computer as is, then you should always check with and discover precisely what “as is� stands for. Do not get faked into expending a good amount of cash over a machine because it was once great. Determine if it really is running properly and ensure that there aren't any critical viruses or difficulty with the way in which it operates.

Refurbished laptop computing devices are an excellent way for you to get a superior just like new machine for a cheaper price. Just simply bear in mind the actual difference of used and restored and also what people you might be obtaining the laptop computer from prior to deciding to make a major investment over a laptop portable computer.

Understanding The High Voltage Transistor In Computer Monitor

Understanding The High Voltage Transistor In Computer Monitor

Author: VineetB



High voltage transistors are transistors with higher specification than the normal transistor. It is usually located in the area of power transformer such as the switch mode power transformer and flyback transformer. In television and monitor that uses the flyback transformer to generate high voltage, a high voltage transistor is required to perform the job. It's location mainly beside the flyback transformer and attach to a heat sink in order to transfer heat faster. Otherwise it may blow in a very short time due to the hard work of this transistor in switching. Typical part number of high voltage transistor that used in monitor and TV is BU2508DF, C3998, C5148, C5047, C5589, C5803 and etc. Usually their rating of volt, amp and watt is in the 1500 volt and above, 10 amps, 50 watt and more. Their sizes are much bigger than the common signal transistor. If this high voltage transistor is shorted, you have to find the exact replacement part number in order for the equipment to last longer. Substitution part number usually won’t last long-perhaps in the few weeks or few months time and it will blow again unless you know the storage and the fall time of the transistor.

Higher voltage, ampere and wattage will not guarantee that your transistor will last long. Many times a bigger specification will blow in a split of seconds the moment you switch on the equipment. You have to go to that particular manufacturer to get the transistor datasheet and find out the spec of the transistor. Look for the fall time and storage time value. The original and the replacement value should have tolerance of not more than 20%. If not the replacement transistor will run hot and eventually blow the transistor. This will waste your precious time.As to why sometimes even the nearest specification transistor also won't work well is because the particular equipment such as monitor-the yoke coil and the flyback transformer is designed based on the specification of the transistor.

Thus, only original part number transistor that can be install in that particular equipment. I have seen even the original number with different batch of transistor when install in the monitor causing the display to curve in (pincushion out) and the transistor runs very hot. I've checked all the circuit and components that connected to the transistor to be okay. Even replacing the flyback transformer also won’t help. The transistor's temperature keeps rising and if I don't turn off the monitor, I believe it will eventually blow the transistor. I took out the transistor and compared with the original one and discovered that the replacement logo is a little bit different from the original transistor logo. When I called my electronic supplier about the logo, they said that the transistor that I bought is of a newer version, thought from the same factory. After long hour of searching for the original transistor, I managed to find one. Unbelievable, the original transistor that i replaced runs cool and the picture is perfectly fine. Guess what is the high voltage transistor part number? It was C5148!

In another case, there was one Monitor came in with no power symptom. Upon carefully check the high voltage area; I confirmed that only HOT shorted causing no power. After the replacement (the part number was BU2508DF), when the monitor is switch on, the power blink. I thought that there was some other bad components are causing the power to blink. I check again the power and high voltage section but just could not locate the fault. I took out the HOT that I had just replaced and realize that it was a little bit different from the original one. I took out another HOT that is exactly the same from my spare parts compartment and voila the monitor works perfectly okay. I begin to compare both HOT and you can clearly see the different from the picture shown below.

The lesson that I learned from this mistake is always must replace with an original part number (if possible) and don’t buy any components that is cheaper than the normal market price.

How to Write a Master's Thesis in Computer Science

How to Write a Master's Thesis in Computer Science

Author: Maki Kopper

The Master's Thesis in Computer Science is considered as practice for the PhD thesis. MSC research thesis is too hard to embark on without research. The vital requirement of a Master's Thesis is that it factually reveals the mastery: that you have fully understood the state of the art in your MSC research thesis and that you are competent of working at that level. This is principally significant when the function to be achieved by the structure is too complex to be explained in code, or maybe the condition-action mappings are unidentified in Masters Thesis.
Writing a Master Thesis is an important task. Though in some ways, Master’s Thesis appears comparable to many other structures of academic writing like research paper, dissertation and essay.
The MSC thesis offers the challenge to demonstrate your ability to set up and to carry out a scientific research project in a self-responsible and independent manner. MSC research thesis includes:


• To provide a sufficient explanation and meaning of your research topic,

• To build a sound hypothetical structure for direction of the research,

• To collect data in a systematic and confirmable way,

• To analyze the data significantly and suitably,

• To present the results in an understandable manner,

• To draw sound conclusions based on a thorough discussion of the outcomes, and

• To show the prospective involvement of your research to the procedure of theoretical modernization of the topic
Emblematic questions that need to be answered during a Master Thesis:
* What problem are you solving?

* Why is this problem imperative?

* Who else is working on this dilemma, on allied research?

* What process have you used to solve this problem?

* Why did you select this process/technique? Is this method superior to other methods?

* What was the most complicated part of your work?

* What are the lingering troubles?
We know this all sounds understandable, but every year there are students who get so marsh down in methodological aspect that by the time they are prepared to defend, they cannot persuasively answer these questions. So, you are preparing to write a Masters Thesis in a tentative area of Computer Science. Unless you have written many formal documents prior to, you are in for a revelation; it's complicated.
Good writing is necessary in a MSC research thesis. However, good writing cannot recompense for a rareness of ideas or impressions. Quite the differing, a clear appearance always exposes flaws.
If you simply follow the implications outlined and discussed in this paper, you will be well on your way to fruitfully carrying out the Master Thesis requirements for achievement of a Master's Degree in Computer Science at any Institute of Technology.

Networking Interview Questions

Networking Interview Questions

Author: B. Bashir

Computer Networking Interview Questions

Here are the basic interview questions for the network administrators, system administrators and IT manager posts. These questions provide the basic information about the network communication technology, network topologies, network troubleshooting techniques, network devices and the basic overview of the LAN/WAN communication model.

What is DHCP?

DHCP stands for Dynamic Host Configuration Technology. The basic purpose of the DHCP is to assign the IP addresses and the other network configuration such as DNS, Gateway and other network settings to the client computers. DHCP reduces the administrative task of manually assigning the IP addresses to the large number of the computers in a network.

What is DNS and how it works?

DNS stands for Domain name system and it translates (converts) the host name into the IP address and IP address into to the host name. Every domain and the computer on the internet is assigned a unique IP address. The communication on the internet and in the network is based on the IP addresses. IP addresses are in this format 10.1.1.100, 220.12.1.22.3, 1.1.1.1 etc. IP addresses can’t be remembered but the host names (e.g. www.networktutorials.info, xyz.com, abc.com) are easy to remember instead of their IP addresses.

What is a Firewall?

Firewall is a protective boundary for a network and it prevents the unauthorized access to a network. Most of the Windows operating system such as Windows XP Professional has built-in firewall utilities. There are the large number of the third party firewall software and the basic purpose of all the firewall software and hardware is same i.e. to block the unauthorized user access to a network.

What is WAN?

WAN stands for wide area network and it covers the broader geographical area. Basically there are three types of a computer network LAN (Local Area Network), MAN (Metropolitan Area Network) and WAN (Wide Area Network). The communication in a WAN is based on the Routers. A WAN network can cover a city, country or continents.

Define VOIP Communication Technology

VOIP stands for Voice over IP and this technology is used for transmitted the voice over the IP based long distance network to make phone calls. VOIP phone calls are very cheap and a large number of the corporate offices and home users are using VOIP technology to make long distance phone calls.

What is Wi Max Technology?

Wi Max is a wireless broadband technology and it is a advance shape of the Wi Fi (which was a base band technology). Wi Max supports data, video and audio communication at the same time at a very high speed up to 70 Mbps.

Define Network Gateway

Network Gateway can be software or a hardware. A gateway is usually a joining point in a network i.e. it connects two networks. A computer with two LAN cards can act as a gateway.

What is a Router?

A router routes the traffic to its destination based on the source and destination IP addresses, which are placed in the routing software known as routing table.

How Fiber Optic Cable Works

Fiber optics provides the fastest communication medium for data and voice. Data can travel at the speed of light through the fiber optic cables. ISPs and corporate offices are usually connected with each other with the fiber optic cables to provide high speed connectivity.

What is File Server?

A file server is a computer in a network that authenticates the user access in a network such as Windows 2000/2003 Servers.

Define Seven Layers of OSI Model

There are seven layers of the OSI model. The basic purpose of these layers is to understand the communication system and data transmission steps. The seven layers are Application, Presentation, Session, Transport, Network, Data Link and Physical. You can remember the name of these layers by this phrase. “All people seems to need data processing�.

Define GSM Technology

GSM is a short range wireless technology and is usually used in the mobile phones, hand help devices, MP3 players, Laptops, computers and in cars.

A Simple Reason-Why your Computer Freezes Frequently?

A Simple Reason-Why your Computer Freezes Frequently?

Author: Peter Paul

The computer system is being freeze and you can’t judge out the exact reason. Is this the case with you? Well, if you can prepare, then there goes a long list of the possible reasons. The most common could be your Windows registry. This is the most integral part of your system, whenever your operating system needs to load some application or access some data. Even when the operating system gets loaded itself, the registry keeps track of the valuable information.

In other words the Windows registry is a repository of all the information like which hardware are attached, computer memory set up, which system files are required to present when the operating system gets started etc. To access even a single bit of data, the system software will access the registry to determine the file location and version like information.

The incorrect or corrupt entries in the registry may raise several complications for the OS, which may be confusing to it and the ultimate result could be the slow response or probably non-functioning (freezing) of the system. Some of the weirdest situations may also raise the need of data recovery. These mishaps can be the product of incorrect play with them or may be due to some external reasons like viruses. The dynamic nature of the system and the installed programs and latest service packs and update installations may also contribute in this regard.

The third party applications, registry cleaners, can address few of the related problems. These software are able to clean and repair few of the errors and find out the incorrect and invalid entries to fix them.

But if the corruption is extensive in nature, being unresolved by the registry cleaner software, the situation is the clear threat to your data. As this is the requirement of reinstalling the operating system and hence formatting of the primary partition of the hard drive. If the primary partition do poses some relevant information related to your organization or the dynamic partition has been used, the loss is all yours in terms of data.

Fortunately, there is a mean of overcoming the situation, called data recovery software. For Windows operating system these are specifically called Windows data recovery software and have the power to scan the hard drive through the use of the influential algorithms and thus give the results of data recovery.

Giving the abstract view to the users through their intuitive interface, the software comes with varying number of features. So there is nothing to worry about the easy data recovery options.

Stellar Information Systems Limited, being the foremost data recovery company, provides you the most supreme solution for data recovery-Stellar Phoenix Windows Data Recovery. This data recovery utility maintains the primacy by the use of powerful algorithms, oriented for perfect and complete data recovery. Suitable for FAT and NTFS file systems, the software is the well built tool to address each data loss poser, identifying each kind of file.

Disk Maintenance with Disk Utility and fsck

Disk Maintenance with Disk Utility and fsck

Author: brad jerry

For the Mac operating system, Apple has offered a wonderful tool for ending the disk-related tasks- disk utility. One more utility is there which checks the consistency of the file system. Both these utilities perform wonderful tasks and are able to address few of the startup issues in Mac.

These utilities can also be used for the perfectly running systems, just to check the inconsistency problems with the disk and the file system, if any. There are few symptoms and error messages which make you feel that you need either of the utilities. Some file system errors may prevent the system from boot which can be the outcome of the unexpected system shutdown. Your computer starts but either it won't reach the login screen, or it may reach the login screen but not load the desktop after you log in. These are the cases when you need disk utility to get access to your valuable data.

The first approach should be to start the system in the safe mode. But if the problem persists then using disk repair is andatory. The disk repair performs various tasks for verifying the disk integrity and repairing if the disk is damaged in few of the cases.

fsck is a command line utility which is recommended if the disk utility is not able to perform the task. These are the cases when you can’t start with the safe boot or the optical drive isn’t visible. fsck utility provides options for either interactively repairing damaged file systems ,automatically deciding how to fix specific problems, or reviewing the problems that need to be resolved on a file system without actually fixing them. Thus this prevents you from Mac data recovery options.

But sometimes both these utilities don’t act as the perfect answer for the complicated data inaccessibility problems. These may yield the error messages like:

“overlapped extent allocation�

Or

“The underlying task reported failure�

In few of the cases the incorrect application of the utility leads to the problems, needed to be addresses by anothe alternative, like running fsck on a mounted file system can potentially cause severe data corruption/loss.

Alternative to fix the problem of the data inaccessibly due to hard drive damage and file system related issues are termed as Mac recovery tools. If this is the case of some physical mischief with the hard drive, then you need to fetch it to Mac data recovery services and for rest of the reasons, Mac data recovery software would be a great deal.

Stellar Information Systems Limited is the company which avails you both the solutions. Data recovery Mac service is provided in the Class 100 Clean Rooms by the expert and the experienced Mac data recovery professionals. They undergo a wide analysis of the affected hard drive and take the respective measure.

Stellar Phoenix Macintosh Data Recovery software is the most ultimate and exquisite Mac recovery utility accomplishing the dat retrieval tasks in all the possible data loss cases. The software is applicable with HFS, HFS+, HFSX and HFS Wrapper file systems.

Remote Computer Repair. Is it Safe?

Remote Computer Repair. Is it Safe?

Author: Mark Tabesh

Remote computer repair is still a new idea to many; however it’s been available to you for years now. Rather than an expensive on-site visit, technicians connect securely to your computer using an advanced screen sharing program. This in turn, allows you to have your computer fixed right away, and at a lower cost due to the lower amount of overhead costs to the companies. But is it really safe?

The short answer is yes. Let me explain why… First, you remain with your computer at all times. When you drop your computer off at the store, you will be asked to return in a week or whenever they finish it. During this time, who knows if anyone is reading or copying your files? Can you be sure they haven’t taken or switched some piece of hardware? Will they even do anything to it before recommending you purchase their new model on isle 9? When having your computer repaired remotely, you’ll be able to watch the repair taking place as it is happening. Your tech should be available for questions through a chat window or the phone if you need him, however no one will know if you are watching or not thus ensuring the techs integrity. Ask your local super store geek if you can sit and watch them fix the computer and see what they say.

With on-site repair, not only do you have to pay very high fees, but you have to wait for the tech to fit you into the schedule when you need your computer working now! Then you must allow a stranger into your home. I’m reminded of a recent news story regarding a national on-site support chain and a camera phone left in a bathroom. If you want to watch what the on-site tech is doing you’ll have to literally watch from over his shoulder because he or she will be sitting in your seat.

With remote computer repair, you must pay with a credit card. Some people still have reservations on using credit cards online. The fact is that credit card companies want you to use their card online for everything. Ask your card company if you’ll be responsible for any fraud or stolen activity. You’ll likely be happy with their response. Plus if you think you are getting ripped off by the online computer repair service, you can use your credit card company to dispute the charge. Note: that a bank debit cards with a Visa or MasterCard usually don’t offer dispute services.

Because this new option for residential computer repair is so popular, a lot of new companies are sprouting up constantly. There are a few important things to look for in a remote computer repair service. Are they in the same country as you? This important because if laws are different, you’ll have a tough time disputing a problem with them should you come to have one. Do they have a No Fix, No Fee guarantee? Many per minute or hour services charge you for their time and do not guarantee to fix anything. What does that say about their trust and training of their own techs? Finally, be cautious of an insanely low price. In my experience, low pricing always means inexperience or a scam. You can expect to get a better deal than any in-shop or on-site service however.

So the next time you have a computer problem, give the remote approach a try. If you find a no fix, no fee guarantee companies then you truly have nothing to lose and such a convenience to gain.

Deciding Between a Custom-Built and Pre-Built Computer

Deciding Between a Custom-Built and Pre-Built Computer

Author: LeeCooper

Deciding Between a Custom-Built and Pre-Built Computer
In the Computer Stone Age - say, 25 years ago or so - just about every computer was custom built. Before the big computer makers turned PCs into commodities, you would order a certain motherboard, a certain CPU, a certain amount of RAM (at up to $400 a megabyte in the mid-1980s) and even specify the wattage of your power supply. Then the marketing people took over from the entrepreneurs, and pre-built computers started to rule the roost.
Today, computer components have become so powerful and so relatively inexpensive, and manufacturing processes so sophisticated, that it is a simple thing for the "majors" - Dell, H-P/Compaq, IBM, Gateway - to offer custom-built computers as well as pre-built ones. How do you decide what is best for you?
What'cha gonna do?
The most important consideration is what you are going to use your computer for. If you are going to do some word processing, web surfing, music playing and a little photo work, an off-the-shelf pre-built computer is the way to go. Unless you have some high-octane processing to do, such as high-end game playing or professional video editing, you don't need anything more than a company's entry-level model. You could probably even make do with two- to five-year-old technology, even, if you don't mind buying used or refurbished PCs without warranties.
On the other hand, if you are going to make more demands on your computer, you need more horsepower. For gamers, it is not just the CPU (Central Processing Unit, or "main brain") strength that matters. Today's computer games also require a great deal of graphics processing, meaning more powerful graphics subsystems. The lower-end computers have less powerful graphics chips "integrated" on the main circuit board, while higher-end machines have separate graphics "cards."
More money vs. more smarts
If you need more power, for games or video or what-have-you, and don't really know the technical side of things, get a more expensive computer. The CPU and the graphics subsystems are the first things that computer makers upgrade as they fill out their lines. If you do know the tech stuff, then you are the kind of person who can do well in the custom-built computer market.
Remember that "custom-built" can mean a few different things. For Dell and HP, for example, it means starting out with a basic, "barebones" setup to which you add your choice of standard or upgraded components. However, there are a thousand and one (a million and one?) PC storefronts around the country that offer "custom-built" computers, and this time the term involves real customizing. With this kind of dealer, you can "spec" everything from the computer case and power supply to the amount of RAM, the kind of CPU, the size of the hard drive and the sophistication of the DVD burner. Every choice is yours.
Final considerations
Don't spend money that you don't have to spend. Spend only what you need to get the job done, unless you know you will doing other, more power-hungry operations in the near future. In that case, spend what you need to and get the capability that will hold you for at least a year. Whether you go with a pre- or custom-built computer is not as important as what you need to do, and how to do it cost-effectively. The fact is that a solid, capable, new computer can cost as little as $200-300 now, and will do all the basics like web surfing, photo editing and music/video playing right out of the box.
Remember, too, that it is not just PCs that can be approached this way, as Apple offers custom-built computers and various outfitting options for its new Macintosh models, as well. Dealers in used and refurbished computers have also made room for the Mac models, which are now powered by Intel CPUs and share many components with the rest of the PC world now, a real change from the "founding era" of the 1970s and 1980s.
So, for you "power users" out there, whether you want a PC or a Mac, you can have it the way you want it with just a little effort. And you folks who make fewer demands on your computers will find a great selection of pre-built computers that will do everything you want for precious little coin. But now that you've learned a little more about how it all works, deciding between a custom-built and pre-built computer might not be quite as easy as before!

Easy DIY Steps to Fixing a Noisy Computer

Easy DIY Steps to Fixing a Noisy Computer

Author: Dave C

There's nothing more irritating than a noisy, overheating notebook when one is trying to stay focused on tasks at hand. Listed below are a few simple tips that can hopefully enable you to restore your laptop to function quietly and efficiently.

I don't know about you, but I can't imagine how I'd survive without my laptop. It takes up much less workspace than a desktop PC would, however if I require to use a computer away from home or the workplace, I can simply pick it up and take it with me, enabling me to work on the go . But when I'm trying to concentrate, there's nothing more irritating than the hum of its fan. I am also amazed at just how hot it can become when it's sitting on my lap.
Too much noise and high temperature are typically the notification signs of an inefficient laptop that's wasting power.

Fed up with the racket as I watched the battery level drain quickly before my eyes, I decided to look into what I might figure out to bring my previously reliable machine back to full power and efficiency - and how to make it run more quietly, too.

It turns out that both laptops and desktop PCs can be easily tweaked to run cooler, faster and quieter. Not all the options covered throughout this article are straightforward to implement but, depending on your level of expertise and confidence, you can have a quieter work companion within no time.

How to repair a noisy, overheating laptop
Probably more than likely the culprit for a noisy laptop is going to be its cooling fan. But before you start panicking about the complexity of replacing the fan, there is a easy way to reduce the noise output. The only things you will require are a screwdriver and a can of compressed air.
First of all, ensure that your laptop is turned off. Afterward remove the battery and unplug the AC adaptor. Look for an air vent on the outer edge of the laptop; there should be an access panel on the base nearby. Loosen the panel and remove it. The fan should be directly underneath. This design isn't universal, but nearly all laptops use a similar chassis and internal configuration.

Now it's time to blow out the dust. You may possibly consider doing this outdoors rather than indoors. Blow the fan with small bursts from various angles, blowing most frequently in the direction of the air vent.
If you're using an air compressor, keep the pressure relatively low and don't get too close with the nozzle. You don't want to damage any of the internal components.

Raising your laptop just an inch or so away from your lap or desk can also considerably improve things. Not only will this increase the airflow around the vents on your laptop, which means the fan won't have to work as rigorously and won't be as noisy, it'll additionally prevent whatever lies underneath the laptop from getting hot.

Most laptop cooler stands also allow you move the display closer to eye level and place the keyboard at a more ergonomic angle.
There are many notebook stands accessible in the marketplace and Kensington's Easy Riser Cooling Notebook Stand is a good example. It's suitable for laptops with screens sized from 12 to 17in and it folds flat for easy transportation. The tiltable plastic device features a lip and rubber pads to grip your laptop into place. You can then adjust both the incline of the display and the base - thereby altering the height - to achieve a comfortable viewing position. Note that you will need to use a separate keyboard, however, since the stand doesn't afford a comfortable typing position.
If you don't want to cart around a spare keyboard, or you'd prefer to sit your machine on your lap instead of a desk, Antec's Notebook Cooler 200 is ideal. The device rests on your lap, with the laptop placed on top. It contains a 200mm USB-powered 'Big Boy' fan that runs at either 400 or 600rpm, depending on the amount of cooling required. The Antec isn't a cheap buy, however it's recommended for high-spec laptops.

If you own a mid-range laptop, you'll probably have a preference to shell out less and acquire a less high-tech solution. A high-quality device at this point is the Targus HeatDefence for Laptops This quilted plastic mat is filled with heat-absorbing crystals that liquify as they absorb heat and crystallise as they cool. Be warned that as soon as the crystals liquify under the part of your laptop base that gets hot, the underside of the pad in that location can become pretty warm itself. You can simply turn the mat to move a crystallised part under the hot spot.
The 10mm-thick Targus HeatDefence is suitable for laptops with screen sizes up to 15.4in and is available in red or black. It's easy to fold up and take with you, so expect to be able to spread it out and get to work wherever you may possibly be.

It's not always the fan that is to blame for a noisy laptop however. The hard drive has a number of moving parts that can produce a racket as they spin. Although you can't essentially silence the hard drive, it's worth taking into account that solid-state disk (SSD) drives have no moving parts and are therefore quieter than traditional hard drives.
If you're feeling sure of yourself, exchange your hard drive with an SSD. Alternatively, if you are wishing to upgrade your laptop, it might be worthwhile considering a model that uses an SSD.

Microsoft developed many programs and they put safety in them to prevent hackers from getting the information that you have input. The Active X software helps for those who like to play games online to keep the PC safe. Microsoft windows offers service packs, critical updates and patches that you need. Still before you do install any update make sure that you have your PC set to the NOTIFY me when new updates are released.

Never go into an unknown neighborhood looking for the best deal on line. Make sure that the address has an (s) at the end of the http(s) because the (s) means a secure site.

You probably never need to purchase it is just used for your enjoyment. Then there are other websites that you use to arrange travel, rental cars, motels etc. these sites need more protection because you are releasing vital financial and personal information. Then you should change your password often and make sure that you use a difficult password. Then the high secure websites that cover your bank accounts, investments, credit cards and personal information for your clients should have a very secure password changed monthly along with an anti-virus software program that you can update.

Make Beats On Computer

Make Beats On Computer

Listening to music is a good way to relieve stress, express yourself, and let go of all the tension building up in you. Of all the music genres existing today, there could probably be nothing that is as close to Hiphop in making you feel in the mood and uplifted. With its different beats and styles, you would definitely be bouncing all your worries away.

Hiphop is said to be a culture: a combination of art, fashion and music. Originating from the African Americans, a rapper named Keith Cowboy coined the term 'hiphop' during the time when he was singing a song to a friend who is off to be part of the US Army. Since then, the evolution of Hiphop as a music genre has been dramatic. With various artists focusing on Hiphop, the world has known of it and has been introduced with its distinct upbeat qualities and urban poetry.

With beats that are a mixture of different sounds created either manually or digitally, Hiphop as a music genre is not complete without the pulsing sounds that seem to make anyone groove and jounce to its rhythm. Hopping and bouncing cannot be helped when this music is played: this is because Hiphop gives a certain "feel" to the atmosphere, which is basically why it is a favorite in clubs and other parties. A lot of effects also add up to the overall impact of the music. And with the current advancements in technology, Hiphop is redefined to make a fuller and richer mixture of a variety of sounds and effects that could not be found in any other means.

As Hiphop artists, musicians are very particular with the technicality of the music that they create. They often seek for innovations or new ways to improve their performances, and a very significant aspect that may help in attaining such is the introduction of digital mastering. As opposed to popular belief, music is not a random mixture of musical elements and sounds: which is basically why it is called art. With this, Hiphop makes it to the list of genres because it is not just haphazardly positioned notes, tunes, and beats; rather, it is a work-of-art that is a gift to mankind.

Many times you buy a music production program and you find out eith its way out of your league or it under delivers, then your stuck with something you are not happy with so... Which ever music production software you choose make sure you do have a chance to try it out first before you buy or at least have a chance to get your money back if you don't like it. With digital mastering and integration of other music techniques, Hiphop is brought to its finest. Whether it is for a career in the music industry or just for fun, anyone who wants to appreciate and experience the unique feel of Hiphop may do so by listening to some of the best tunes available online today. Visit Make Beats On Computer for high quality music that everyone can enjoy!

How to Hook Up a TV to a Computer as an Alternate Monitor

How to Hook Up a TV to a Computer as an Alternate Monitor

Author: miss ec

My computer right now is hooked up to my 53" TV across the room. It's a pretty cool trick, and if you have a computer and television in the same room you should see if you have a way to hook them up. Doing actual work is best on a real computer monitor (LCD preferred, but CRT acceptable), but watching videos, playing games, and surfing the web are pretty fun things to do from the couch.

The resolution of TVs compared to actual computer monitors is pretty bad, unless you have an LCD tv. Mine is not, but even still I find that it is a very cool thing to have hooked up, and it works just fine for watching movies/videos. Games are doable if there isn't a lot of text on-screen that you have to read, but you won't be chatting to your buddies in World of Warcraft if you want to keep from going blind.

Word processing / web browsing is tolerable, but can be eye-straining after long periods. Definitely increase the text size as big as you can stand it for reduced eye strain. All in all, I just use my TV for videos because it's much easier to just sit at my desk and use my computer LCD monitor for doing actual work.

Most newer video cards have an S-video port on them, and this is the easiest way (and the way I use) to hook your TV up to your computer. Some newer video cards will also have other outputs, and some newer TVs will have VGA or DVI inputs to take a regular monitor cable. Just look at the ports on both devices and you should be able to tell if they have one in common, then you just have to figure out what they are. If they do not have one in common, look on your TV for an S-video port (it's a black circle about the width of your finger), and if you find one, you just need to buy a video card (they can be had for less than $100) that has an S-video out.

Once you have them hooked up with a cable (S-video or otherwise), you'll need to go into your driver settings on the PC. In Windows, right-click on the desktop and hit Properties to access the Display Properties window, then go to the Settings tab. On some video cards you can select/enable an alternate monitor (the TV) right from this window, but on most video cards you have to click the Advanced button and configure it there.

Most of the good video cards will let you display the screen on both devices (your monitor and your TV) simultaneously, but the geForce card I have right now will only let me use the two displays as side-by-side desktops. This actually works out better for me, because I can have news or whatever playing on the TV, and keep working on my normal desktop. I'm not sure if you've heard or seen it, but Bill Gates uses a triple desktop on his computer (3 LCDs) -- I hope you're as jealous as I am!

Computer Careers: Your First Job And Salary Hype

Computer Careers: Your First Job And Salary Hype

Author: Chris Bryant

Computer careers can be highly lucrative, and I'll be the first to say that starting a career in information technology is one of the smartest decisions I ever made. Most computer training schools and tech schools are realistic with you about the kind of money you can make in getting started, but occasionally I still hear radio ads for schools using a salary survey or "average salary" as a recruiting tool.


This is in no way meant to talk you out of starting a career in computers, but keep in mind that the average salary survey in no way reflects the kind of money you should expect to make when starting out in IT. One recent survey I read reflected an average salary of $70,000 a year. While you can certainly make that kind of money in a computer career - and frankly, you can make even more - there are so many other factors involved in an "average salary" that I'd go as far to say that there really isn't such a thing as an average salary. Salaries are affected by your geographic location, your certification, your education, and your job role.


As I've written in other computer career articles, the most important factor in your first job should be the experience you will gain. Make sure to use long-range planning when it comes to your IT career, and ask yourself "What will my resume look like in two years if I take this job?" Once you get a little experience to go along with your initiative and computer certifications, you'll be unstoppable - and you'll be able to make more than any "salary survey" says you will make!
