Operating System (OS) / System Software Types and examples

Operating System is a software that commands over hardware as well as application software. It is also known as system software because it is responsible to run that system.

You can not use any computer or mobile device(s) without an OS. An operating system has three main functions:

  1. Manage the computer’s resources, such as the central processing unit, memory, disk drives, and printers,
  2. Establish a user interface, and
  3. Execute and provide services for applications software.

Types of Operating System(OS)

There are basically 4 types of Operating System (OS).

  • Single User OS
  • Multi-User OS
  • Single Tasking OS
  • Multi-Tasking OS

Let’s understand one by one:

Single User Operating System

It allows a single user at a time. Only one user can perform an action in this OS. Multiple users are not allowed in this OS. You can only execute instructions. E.g. Windows 9x, DOS.

Multi-User OS

Multiple users can perform an action at the same time. It can be possible only client-server architecture. Everywhere we can see the example of Multi-User OS. Indian railway reservation is a big example of multi-user OS. We have other examples too.

Single-Tasking OS

These types of OS perform only a single task at a time. If you are working on MS-Word so you can not listen to any music etc. E.g. Ms-DOS, Windows 95
