A computer system has both hardware and software.

The hardware component of a computer classified into 4, they are

The Input Unit

The Output Unit

The Central Processing Unit

The Memory Unit

These units are interconnected by electrical wires which allow communication between them.

Input unit

A computer uses input devices to accept the data and program from user. Some example for Input devices are keyboard, mouse, light pen, touch screen.

Output Unit

Output devices used to display final results to the user. Example monitors, Printers

Central Processing Unit

CPU is the brain of computer system. Which control all the operation of computer. It consists of arithmetic and logic units (ALU), which performs all arithmetic and logical operations. Control unit that control hardware operation and internal memory used to store data in memory.

Memory Unit

In this , the computer stores the program and data that are currently being used. The main memory holds data temporarily so secondary storage devices is used to provide backup. Secondary storage devices can hold more storage than main memory.

There are basically four main components of computer and they are Input devices, Output devices, Processing unit and Memory of computer. Input devices are used to input data to computer. Output devices are used to to take data from computer. Processing unit is used to process the stored data and Memory unit is used to store data.

There are different parts of computer which help in its effective functioning and processing. They are used to make processing of data easier. Computers parts are made up of many different parts. These parts are made up of smaller parts, called components. No computer can function without these components.
