Examples of Sinlge Multiuser Operating System

For example Unix, Linux, Windows 2000 server

3) Single Tasking operating system

An operating system that allows the user to perform only one task at a time is called single tasking operating system.

Examples of Sinlge Tasking Operating System



For example, DOS is a single tasking operating system. In DOS, you can type and execute only one instruction at a time. you cannot use another command untill the first command is completed.



4) Multi Tasking operating system


An operating system that allows the user to perform more than one tasks at a time is called single tasking operating system.

Examples of Multi Tasking Operating System


For example Windows, Unix, Linux are multi tasking operating systems. In MS Windows we can perform many tasks at the same time. For example, we can type some letter in MS Word while listening music in an audio player software at the same time.



5) Stand Alone operating system

An operating system that works on a desktop or notebook computer is called standalone operating system,

Examples of Stand Alone operating system


for example DOS, Windows 2000 professional etc

6) Client operating system

A stand-alone operating system that works with a network operating system is called client operating system. e.g. Windows 2000 professional, Windows NT workstation

7) Network operating system


An operating system that supports network is called network operating system. It normally works on a server. Some examples of network operating system are Windows NT Server, Windows 2000 Server, UNIX, and Linux etc.

8) Real Time operating system


A real time operating system is a very fast operating system. It responds to a certain input extremely quickly.

Examples of Real Time operating system

Real time operating systems are needed to run medical diagnostic devices, machinery and industrial systems.

Some common examples of real time operating systems include:


  1.  Air Traffic Control Systems, 
  2. Command Control Systems and
  3. Networked Multimedia Systems.
  4. Real time OS for Medical diagnostic devices
  5. Real Time operating systems to run ATM machines

9) Time sharing operating system


A time sharing operating system is an operating system in which many users can execute their tasks nearly simultaneously. Operating system allocates a very small time period to each task. All tasks share CPU time. CPU executes each task for a very small time period turn by turn. CPU is so fast that all users think that CPU is doing their task.
