Advantages:
- Advantages:
- Provides the advantage of quick response.
- Avoids duplication of software.
- Reduces CPU idle time.
- Disadvantages:
- Problem of data communication and security.
- Problem of reliability.
What are the advantages of time sharing operating system?
It provides the advantage of quick response. This type of operating system avoids duplication of software. It reduces CPU idle time….
- Time sharing has problem of reliability.
- Question of security and integrity of user programs and data can be raised.
- Problem of data communication occurs.

What is Time Sharing System explain?
time-sharing, in data processing, method of operation in which multiple users with different programs interact nearly simultaneously with the central processing unit (CPU) of a large-scale digital computer. Commonly used time-sharing techniques include multiprocessing, parallel operation, and multiprogramming.
How is time sharing usually implemented?
A time shared operating system allows multiple users to share computers simultaneously. A time shared operating system uses CPU scheduling and multi-programming to provide each with a small portion of a shared computer at once. Each user has at least one separate program in memory.
Under what circumstances would a user be better off using a time sharing system?
A user is better off under three situations: when it is cheaper, faster, or easier. For example: 1. When the user is paying for management costs, and the costs are cheaper for a time-sharing system than for a single-user computer.
What are the examples of time sharing operating system?
Some Examples of Time Sharing Operating System
- UNIX.
- Multics.
- Linux.
- Windows 2000 server.
- Windows NT server.
- TOPS-10 (DEC)
- TOPS-20 (DEC)
Is an example of timesharing scheduling policy?
Explanation: In order to schedule processes fairly, a round-robin scheduler generally employs time-sharing, giving each job a time slot or quantum (its allowance of CPU time), and interrupting the job if it is not completed by then. It is designed especially for time-sharing systems.
What is the priority of a real time task?
Most real-time systems are priority based. – Priorities are application-specific. The scheduler always gives the CPU to the highest-priority task which is ready to run. Context switches occur only when tasks explicitly give up control of the CPU.
When the process issues an I O request?
Explanation: When the process issues an I/O request it is placed in an I/O queue. I/O is a resource and it should be used effectively and every process should get access to it.
Which generation time sharing became possible?
Time-sharing became possible with the second-generation computers. In today’s era, a specialized computer can serve multiple users at the same time.
What is the purpose of interrupts?
Interrupts are commonly used by hardware devices to indicate electronic or physical state changes that require attention. Interrupts are also commonly used to implement computer multitasking, especially in real-time computing. Systems that use interrupts in these ways are said to be interrupt-driven.
