Important Information About Computers

A short definition of a computer is that a machine use to perform calculations automatically. The basic origin of computer is related to computing. In this modern world everybody should know how computers work. One should know about the different components of a computer. Let's discuss the main parts of a computer.

1) CPU (central processing unit) is the main part. The other devices required to complete your computer set are monitor, keyboard, speakers and mouse. Mainly central processing unit is the combination of four parts. These parts are ALU, control unit, RAM and ROM.

2) ALU is the abbreviation of arithmetic logic unit. ALU can perform two types of functions. These functions are arithmetic and logic. Arithmetic function solves all the mathematical problems such as addition, subtraction, multiplication and division.

3) Another very important part of CPU is control unit.

The brain of human controls all the activities happening in the body. Similarly control unit acts as the brain of computer. It controls all the activities happening in the body of a computer. It controls all other parts of the computer.

4) A very useful component of a computer is the memory. There are two main categories of a computer memory; one is RAM (random access memory) and the other is ROM (read only memory). RAM can read and write anytime when CPU commands it, but ROM is pre-loaded with data and software that never changes, so the CPU can only read from it. ROM is used to store the computer's initial start-up instructions. In general, the contents of RAM are erased when the power to the computer is turned off.
