Definition of a computer

A computer is an electronic device which is capable of receiving the inputs (data from the user), storing it for a

desired period of time, manipulating it according to the set of instructions (called program) and producing the

output to the user in desired form. It performs a variety of operations in accordance to the set of instructions.

Also, Computer is an electronic because it contain some electronic component such as resistor, transistor,

capacitor and integrated circuits.

Your "computer" is a programmable electronic collection of devices that function as a unit which can store,

retrieve and process data. This collection includes a System Unit, a Keyboard, a Monitor and a Mouse.

Advantages of computers:

Increases speed of computing and processing information in any other way.

People can use sophisticated statistical and mathematical tools for decision making and further

purposes without learning in details the algorithms used for computing. This way people can use much

more sophisticated analytical tools that would have been possible with only manual information

processing.

Computers can store large volumes of information without occupying too much space, as is in the case

of information stored in form of books and paper documents.

Computer processing eliminates the human errors of computing and information processing.

Information once entered in computer system can be easily accessed by the same person or other

persons at different times for different persons. This reduces the work load of capturing same

information multiple times for different purposes. It also makes it possible for different person to work

with same information, avoiding the possibility of different persons using different versions of the same

information.

The work of entering and editing information is made mush more easy and simple by software that

offer many powerful user friendly features for performing these tasks.

Computer now offer sophisticated and powerful software for representing information in rich formats

with visual and video facilities.

Computers combined with communication technology offer very fast speed and rich communication

facility at low cost.

Computers, with all these features are now used for automating all kinds of equipments and processes.
