1- The main purpose of the CPU is to execute programs. It does this by doing three basic steps.

a) The CPU uses it ALU (Arithmetic/Logic Unit) to perform mathematical operations like addition, subtraction, multiplication and division.

b) Moving data from one location in memory to another.

c) Making decisions and jumping to a new set of instructions based on those decisions.

2- It's works as brain of your computer...

3- CPU purpose is to quick reading data

4- Its give the instruction to your computer.its the hard of your computer

5- it is the main processor in a computer that processes all the logic statements put to it.

What is the purpose of the fan in the CPU?

Most heat is dispersed from the CPU by the heat sink - a large aluminium blob stuck onto the actual CPU. The fan is there to assist in the distribution of heat away from the CPU and into the surrounding atmosphere. So CPU's run so cool - laptops, phones etc, don't have a fan as the CPU's run relatively cool, and the heat generated can be dispersed by convection.
