Computer Processor : What is it?
 A computer processor analyzes data and controls data flow. Also called the central processing unit (CPU), it is considered the “brain” of the computer because it performs the actual data processing. It carries out instructions of the program sequentially to execute the basic logical, arithmetical, and input-output system operations. The term “computer processor” has been the jargon used in the industry since the 1960’s. While the design, form, and implementation of processors have changed radically since, their fundamental operation is much the same.

Kinds of Computer Processors include the following:
Intel® computer processor
Intel has been using multicore approach to improve performance and keep up with constant upgrades in the industry. A “multi-core” processor is a chip containing more than one microprocessor core, thereby multiplying performance.
The latest and fastest Intel computer processor for demanding applications is the Core i7, a quad-core processor featuring 8-way multitasking capabilities. This second generation processor boasts the Intel Turbo Boost Technology 2.0 and Intel Hyper Threading Technology, which enables security protocols and applications to run very efficiently in the background without affecting productivity. It also boasts the Intel HD Graphics 2000 Technology, which renders discrete graphics cards non-essential, thereby reducing system cost and power consumption.
Intel Atom, meanwhile, is a line of ultra-low voltage computer processors designed for netbooks, mobile internet devices, and everyday PCs.
AMD® computer processor
The AMD computer processor is exclusively made by Advanced Micro Devices, Inc. (AMD). The latest is Bobcat, an x86 processor core used together with GPU cores in Accelerated Processing Units under the "AMD Fusion" brand. It is designed for low-power devices such as netbooks and similar consumer electronics. AMD is looking to release Bulldozer in the second quarter of 2011.

Quality: Choose a high-end computer processor if you use heavy applications, such as design software and games. It usually costs more, but it provides higher-quality images and graphics. Model: If you can afford it, choose a fairly recent computer processor so you do not have to upgrade for at least 2 years. If the latest is too expensive, opt for an 8- to 12-month old processor, which can save you hundreds of dollars.
Compatibility: Check the maximum processor your motherboard can support. Check the documentation, or the manufacturer name and model usually appearing on the upper side of the motherboard. It’s easy to find information for newer models online. You can also find datasheets for older models.
