Introduction of Operating System

When you start to learn anything in Computer System we have to work on Operating System.
Computer Software can be divided into two main categories:

  • Application Software
  • System Software
Application software consist of the program for performing tasks particular to the machine's utilization. This software is designed to solve a particular problem for users. Examples of an application software include word processor, spread sheet, database system, desktop publishing systems, program development software and games.

On the other hand, system software is more transparent and less noticed by the typical computer user. This software provides a general programming environment in which programmers can create specific applications to suit their needs.

This environment provides new functions that are not available at the hardware level and performs tasks related to executing the application program. System software acts as an interface between the hardware of the computer and the application software that users need to run on the computer. The most important type of system software is the OS.
