Central Processing Unit (CPU)

The CPU is also called miro-processor or simply a processor. It is located inside the computer case on the motherboard. It is termed as brain of the computer because it is one of the most important parts of any computer. The primary job of processor is to carry out the instructions. Whenever you run any application such as Micrsoft Word or Power Point Presentation you are actually sending instructions to the processor.

The processor is very small in size. A typical processor is a two-inch ceramic square with a silicon chip located inside. Chip is generally about the size of a thumbnail. The processor fits into the motherboard’s processor socket (also called CPU socket). Each socket is covered by the heat sink to absorb heat from the processor.

Processor speed is measured in megahertz (MHz), millions of instructions per second; & gigahertz (GHz), billions of instructions per second. Faster processor takes a very little time to execute instructions. However, computer speed depends on the speed of its different different components, ram, latest genaration of processor or latest hardware or technology of computer system.

Nowaday there are many computer processor manufacturers for personal computers or other gadget, but the most well-known company or brands are Intel and AMD.

In the ALU and control units are combined into one unit called the central processing unit (CPU). This is commonly done to separate the actual “brains” of the computer from the other units. In a microcomputer the CPU is usually implemented on a single chip silicon wafer.
