Definition of Computer: Computer is an electronic device which stores data and gives the result consistently. The word “Computer” comes from the word “compute” which means calculate. So a powerful computer can handle some million instructions per second.

Block Diagram of Computer:

A Computer consists of number of components. They are: 1. Input Unit2. Output Unit3. CPU4. Secondary Storage Unit

1. Input Unit Input unit is used to send data (or) programs into computer. They are several kinds of input units are available .They are keyboard, mouse, joystick, light pen etc.

Secondary storage Devices

2. Output Unit Output unit is used to display the results from the computer. They are several kinds of output units are available. They are monitor, printer, projector, speaker, etc.3. Central processing Unit The CPU is most important part of the computer. All devises are connected to CPU. It is also called”processor”. CPU is considered as the brain of the computer. CPU performs all types of data processing operations. It stores data, intermediate results and instructions (program). It controls the operation of all parts of computer. It includes a) Arithmetic and Logical Unit

b) Control Unit c) Memory Unit

a) Arithmetic and Logical Unit: Arithmetic and Logical Unit is used to perform arithmetic and logical operations. Here arithmetic operations like additions, subtractions, multiplications and divisions. Logical operations such as comparing, selecting, matching and merging of data.b) Control Unit This unit controls the operations of all parts of computer but does not carry out any actual data processing operations.Functions of this unit are:

It is responsible for controlling the transfer of data and instructions among other units of a computer.

It manages and coordinates all the units of the computer. It communicates with Input/output devices for transfer of data or results from storage. It does not process or store data.

c) Memory or Storage Unit This unit is used to store data (or) programs. It is also known as internal storage unit or main memory or primary storage or Random access memory (RAM). The primary memories stores data temporarily. Functions of memory unit are:

It stores all the data and the instructions required for processing. It stores intermediate results of processing. All inputs and outputs are transmitted through main memory.

4. Secondary Storage UnitThe Secondary Storage Unit is used to store data permanently. It can store large amount

of data. There are several kinds of Secondary Storage Units. They are hard disk, floppy disk, etc.
