Q. Explain different types of operating system
What is an Operating system or OS
The operating system is the most important program
that runs on a computer. Every general-purpose computer
must have an operating system to run other programs
and applications. The Operating system or OS provides the base on which other programs and applications are installed and executed . Operating systems perform basic tasks in computer systems, like:
Basic Functions of Operating System
- Providing the user interface
- Receiving the input from the keyboard,
- Sending the output to the monitor screen,
- Keeping track of files and folders on the disk,
- and controlling the functions of peripheral devices such as printers, etc.

Different types of operating system with examples
Following are different types of operating system with examples: |
| Explain different types of operating systems |
1) Single User Operating system
An operating system that allows a single person to use or access a computer at a time is called single user operating system.Examples of Sinlge User Operating System
For example, DOS and Windows 95 are single user operating systems.
2) Multiuser Operating System
An operating system that allows more than one user to access a computer at a time is called multi user operating system.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 workstation7) 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:
- Air Traffic Control Systems,
- Command Control Systems and
- Networked Multimedia Systems.
- Real time OS for Medical diagnostic devices
- Real Time operating systems to run ATM machines
- Medical devices, machinery, life support system use Real time operating systems
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.
Operating system uses CPU scheduling and multiprogramming to provide each user with a
small portion of a time. Computer systems that were designed primarily as batch systems
have been modified to time-sharing systems.
Advantages of Timesharing operating systems are following
• Provide advantage of quick response.
• Avoids duplication of software.
