CPU

Definition:
The ** central processing unit ** ( ** CPU ** ) is the component of a computer system that carries out commands of a computer program, to perform the basic operations of the system that the user requires.

Function and Purpose:
There are two typical components of the CPU. One is the arithmetic logical unit (ALU) and the second is the control unit (CU). ALU performs the arithmetic and logical operations, and the (CU) which extracts instructions from memory and decodes and executes them, requiring the ALU when necessary.

In a more understandable context: The CPU is the brains of the equipment where most of the calculations take place to run the computer.

Description and Concrete example of how it affects the end user:
For just normal use (writing letters, playing basic games) a standard 1.8 GHz CPU is very fast. But there is the option of paying more for a computer that will contain a CPU that is faster so future software is able to still run on your computer.

As a bonus faster CPU's also improve Internet speed and game playing for those computer users that are not just looking to accomplish homework, but also interact with social media and other interests.

Recommendations:
If you are looking for a more out performing computer than I recommend purchasing a computer that contains a Celeron, Pentium 4, Athlon XP or a Intel Core i7 (which is common in most Macs) that will base the computer in a 1.8 - 2.8 GHz range.
