WANT TO BUY A COMPUTER?
Having computer today is absolutely a necessity today for your office. Now a days computer allows you to operate your business from sitting at home. Thus saving your time spent in travel as well stress you go through. Or if you have kids then it becomes so much more important to buy a computer for you home. As kids today need as much knowledge and literacy in computer as possible for their brighter future or we can say for even their survival in cut throat competitive world.
Before starting on points to consider to buy a computer, I will like to say that there is every chance after buying a computer in month or so you will find that there are even faster and cheaper computers available in market. So just try and find fastest and best suitable machine with your budget. Because even if technology going to evolve everyday your computer not going to be a junk on table in one day.
Now when we start hunting for a computer, decide if you want to go with branded computer or assembled one. My suggestion will be assemble one as it will cheaper and you can select best components and assemble them together. Only negative point will be for servicing you have to contact different people for different components.
Configuration for computer:- (This will help you select your branded or assembled computer)
Processors (CPUs):
The CPU (Central Processing Unit) is the brain of your computer. In general, the faster the better. Processor speeds are measured in gigahertz (GHz), the fastest models available now is in the range of 4GHz, but this is for mean ******** machines. If you are in ******** animation, gaming industry you can go with it but it will be really expensive. For the basic everyday office or home use processors starting from 1.5 GHz, is good enough. Then you have to make choice between Intel core duo or AMD core duo. General assumption if you want to play games on your machines then AMD processors serves the purpose better. Or Intel is common in use and will be cheaper option than the AMD processor.
Memory (RAM):
Most computers now use a type of memory called DDR2. Some high performance one might use DDR3, but this is quite expensive. Avoid systems using DDR1 or SDRAMS as for the amount of memory go for at least 1GB of memory. Memory speed will have immediate impact on performance as well. More the memory faster the PC. When buying computer try to buy as few DIMMs as possible to allow for future memory upgrades if needed.
Hard Drives:-
Hard drives are where all your data is going to be saved so it is also a very important part of your computers. Now a days Hard drives going down on sizes and going up on storage space. You must have at least 250GB of hard disk. Almost all of them are running at 7200rpm now.
Optical Drives (CD/DVD):
Most of the systems now comes with DVD writer, CD writers are things of past now. And there is no need to make any adjustment in the budget. As for floppy drives, they are part of ancient history of PC’s, nobody use it anyway.
Motherboard:
Choice of motherboard will depend on the processor you have selected, it has to be compatible with processor. You have to take care that, the motherboard you have selected has onboard video graphic card, sound card as well as there is provision for external video card and sound card in case of high end use. The motherboard should allow you to add LAN card, Wireless LAN, Bluetooth, USB 2.0 connectors. And try to have as many USB connectors as possible as most of the Upgrades and Peripherals of computers use USB nowadays.
Cabinet:
This will have to be compatible with hardware you have selected. Ithas to have SMPS into it to power up the hardware. Then it has to as less bulky as possible and with arrangement for air ventilation so that your PC will be safe from overheating.
Monitors:
Monitor is also a as important part of PC as CPU is. Previously when LCD’s were really expensive people used to go with CRT, but now LCD is the option everyone goes for. If anybody think of CRT he goes for Flat Panel CRT. But LCD is still far better because it gives sharper picture, it is not bulky, it occupies lesser space, and it is easy on your eyes too. As for the size 17 inch is standard size now a days. Just take care to buy a monitor which should be capable of 1024 x 768 resolution, you might use most commonly 800 x 600 resolution. But it is always better to have provision.
Input/Output Interference Peripherals:
Keyboard and mouse has to be the first thing to buy as they will help you to communicate with you PC. There are wired and wireless Keyboard and Mouse available in the market so it will depend on anyone’s personal taste.
Then you can add “All in one printer” in your set up which will help you to print, scan, copy as well as fax your documents.
You will also need LAN card installed in your system to connect Internet. As modem is provided by Internet Provider nowadays so you don’t have to worry about it.
Then there will speakers to listen to music and movies, if you prefer to watch DVD’s on your PC then you can add 5.1 home theatre speaker set in your system.
If you want to use your PC for chatting then you need to have a Headphone with Microphone and Webcam of 2 – 3 megapixel.
You can also add TV tuner card to your PC to watch TV on your desktop computer.
Softwares:
After all the hardware in place you have to think about the softwares as they are essentially decides how you want to use your computer. There are two popular and user-friendly operating systems available in the market, WINDOWS and MAC. Windows has captured most of the PC market than the MAC. As it is more compatible to most of the softaware and it has been used by almost everyone it is better bet as it is lot cheaper than MAC, and it is only because of ‘Supply and Demand’ Rule. Don’t judge quality by there price difference. Although buying MAC is in thing now a days, it is somewhat style statement. As MAC’s other product Apple ipod and iphone becoming really popular. So it’s again personal choice.
Then there are various softwares available to enhance the use of your computer, there is MS OFFICE which contains MS Word, MS Excell, Powerpoint, Outlook etc. to help in your office and school, college work. Then there is Adobe, Corel, Macromedia’s softwares like photoshop, coreldraw, Flash, dreamweaver, etc. to help you with your artistic work.
After installing all the softwares don’t forget to install Antivirus software to protect your PC from Virus specially if you are using Internet.
So in Nutshell go and find suitable PC for yourself and enjoy the limitless possible things your PC can do for you.

Computer Processor – Before, Now And Eventually
Kevin Dark asked:
The fact is that a computer comprises several processors however the one regularly used by advertisers when they want to draw attention to the power of a computer commonly relates to the Central Processing Unit (CPU).
Few individuals will not have heard of Intel or AMD processors while their significance to the advertising community and thereby the general public at large is comparable to the way motor manufacturers sell their cars. If in the market for a sports car an individual usually wants as much performance as is available hence manufacturers will sell their most powerful cars simply by stating the number of cylinders a particular model possesses. By using just two letters such as V8 – a message is sent to the public consumer who will automatically recognize that this indicates a potentially powerful engine. The equivalent term to excite the adrenalin rush in the computer buyer today is probably a “Dual Core Processor”.
However before describing the merits of dual core processing or any other electronic component or semiconductors it seems reasonable to first explain why the CPU attracts so much attention, possibly more than any other electronic component lurking within a computer.
The specification of a CPU is defined by its speed for example 900 MHz provides an approximation of the number of instructions that a CPU is able to process by the second – 900 million in this example. In addition the data handling capability of a CPU defines its power: a 64-bit CPU is able to combine, stage-manage or subtract numbers that are 64-bits wide. In the early nineties computers with 16-bit CPUs were considered powerful while today 64-bits are the norm, a reflection of how far the IT public sector experience has developed in a little over fifteen years.
A CPU today would seem like something from an alien world to the computer geeks of fifteen years ago, Not only have they become much more powerful but in addition their use of new materials as semiconductors increases efficiency beyond anything thought manageable fifteen years ago. The intention of these new semiconductors is directly aimed at the speed with which a CPU operates. Making the CPU faster is an ongoing challenge that drives this industry because ultimately all computers are limited by the capability of their CPU and, because IT has become an established ingredient in the daily routine people now have to handle we are much more proficient at using them.
The knock on effect from the IT development of the past fifteen years relates to people and their improved functionality when interacting with computers. The demands made on electronic components will continue to increase as people learn how to add, manipulate and subtract using their IT on a daily basis and it seems that no matter how fast electronic components become they will never quite be capable of matching the speed of the brain whose fingers deftly work a keyboard.
In addition a fast CPU back in the early nineties ran at around 386 MHz, an electronic component that would today freeze being within close proximity of a modern PC game.

What Are The Benefits Of Mobile Dual-Core Processors?
Tim Childree asked:
When browsing through different notebook computer models, you are guaranteed to encounter the “Intel Core 2 Duo” or the “AMD Turion 64 x2″ labels. These labels indicate dual-core processing technology for mobile computing. Multi-core processing is the buzz-word of the day, but what does it mean for you?
Mobile Dual-Core Processors
Mobile dual-core processors refer to a processor system consisting of two independent processor cores combined in one integrated circuit (IC) or, as industry professionals say, in a single die. Basically, mobile dual-core processors place two central processing unit (CPU) cores in one processor. Dual-core processing was first applied to desktop computing and home console gaming, but it was quickly adapted for mobile computing. As expected, AMD and Intel both have numerous mobile dual-core processing options available.
Dual-core processors have a different architecture than twin- or double-core processors. Dual-core processors refer to a processing system where two processors are integrated in one IC die. On the other hand, twin-core processors refer to a processing system where two independent processors – each on its own die – are directly plugged into the motherboard.
Each of the processors in a dual-core processor has a built in cache (Level 1 cache) so each has its own potential for speedy and efficient recovery and processing of frequently used instructions. More than that, however, there is a Level 2 cache, in the same IC board, which the two processors share in Intel’s Mobile Core 2 Duo chipsets (either 2 or 4 MB); In AMD’s Turion 64 x2 chipsets, each of the two processor has a dedicated 512 kb cache per core. The L2 cache is the processor’s backup cache in case the L1 cache is not enough.
The Benefits of Mobile Dual-Core Processing
The foremost advantages of dual-core processors are speed and efficiency. Instruction processing and data retrieval are handled by two processors, so more processing speed can be achieved without overheating either processor. The fact that the two processors have their own easily accessible L1 cache also assures more speed. Furthermore, especially in the case of the Intel Core 2 Duo where the L2 cache is shared, full L2 cache memory can be quickly utilized by either one or both processors as the need arises.
In a nutshell, a notebook computer which has a dual-core processor is assured of fast and efficient processing performance with a greatly reduced risk of overheating. Multi-tasking is much improved. Dual-core processors also consume less power than twin-core processors.
One other benefit of dual-core processors in notebook computers is the possibility of lighter and smaller notebooks that can approximate desktop PC performance. Since two processors share one IC die, one can enjoy the benefits of dual-CPU processing without having to deal with extra bulk.
It is important to note that users of older programs will not see any benefit from their dual-core processors if they only run one program at a time. Older programs were not designed for dual-core processing, so they are only able to take advantage of a single core. A dual-core processor still gives considerable advantages in multi-tasking, however, as each core is able to handle a different program, speeding up multi-tasking considerably when compared to a single-core computer.
As time goes on, more and more software developers are developing their products with dual-core processors in mind, so users will see more and more benefit out of their dual-core processors in the near future.
