CPU: central processing unit
The CPU (or Central Processing Unit) is found within a computer's motherboard. The CPU carries out all of the instructions it is told from the programs installed on the computer. The CPU uses logical operations such as basic maths and input/output operations. A CPU is comprised of millions of transistors, however, because they are so small, they are commonly called "micro-processors". These transistors "process" the instructions given to it from the computer's programs.
The CPU heats up very quickly due to the power and number of instructions needed to be carried out. To fix this problem, a fan is attached to the top of the CPU. The attached fan usually comes with the CPU when purchased.
