Explain Different Types Of Operating Systems
Q. Explain different types of operating system
Following are different types of operating system |
| 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. 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. 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. 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. 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, for example DOS, Windows 2000 professional etc6) 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. Real time operating systems are needed to run medical diagnostic devices, machinery and industrial 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.
