COMPUTER SOFTWARE

A computer is the most versatile machine in the history that has ehanced the mental capability of human and has relieved him from mental labour.

The print routine programme is executed, performing the internal operation needed to print your spreadsheet. Computer hardware is useless without software, that runs the computer for specific task. Similarly software is useless without hardware.

The step in a programme is written in a language that the computer can interpret or understand. It is the programme that controls the processing activities of a computer and tells the computer what to do and is referred as software. In order to produce useful output, the hardware and software must work together.

• Sytem Software: Which coordinate the operation of the computer and helps the computer to carry out its basic tasks.
• Application Software: Which solve particular user problems and helps the user to carry out a task.

They are designed to facilitate the use of the hardware and to help the computer system run quickly and efficiently. They direct the fundamental operations of your computer such as displaying information on the screen, storing data on disks, sending data to the printer, interpreting the typed commands and communicate with peripheral devices. In addition system software provides a foundation so that application software operates correctly and use peripheral devices properly. System software can be divided into three main groups.
