• They actually carry out very simple operations,such as addition and subtraction.
• They achieve their fantastic computing power by carrying out these operations at incredible speed.
• The programme,or set of instructions for operating the computer,is therefore written as a sequence of very simple steps. Several computer languages have been developed for different applications,including BASIC ,COBOL,FORTRAN, and PASCAL.Writing programme is very skilled and time consuming work.
• But for most typical computer applications ready-written programmes are available,called "packages".

• By WAN all the computers of a large area are connected like the computers of all the offices of a city or town etc.
• In India a very large computer network namely INDONET has been installing through which all the main towns and cities has to be interlinked.

Computer Terminology

Bit : 

The bit is a unit of measurement of the electronic data.One bit is either 0 or 1 but not both. On composing 8 bits, 1 byte is formed.

Bug :  

The bug is the error in the computer program or system and its eradication is called debug.

Byte : 

Total eight bits compose a byte.

Thus 8 bits = 1 byte.

CD- ROM:

A CD like of music CD in which data can be stored substantially called CD-ROM.In a CD with comparison to floppy extremely more data can be stored but one problem in it is that one time recorded data can not be deleted or modified.

Chip: 

It is a thin slice on which by a special mechanism a circuit is designed which is normally made from silicon.

Memory system:

The place where computer data and program are temporarily kept is called memory system.Usually memory is implied from RAM.
