Define Time Sharing Operating System.

Definition: Time-Sharing Operating System

A time-sharing operating system is an OS that allows multiple users and programs to share the CPU by rapidly switching between them, giving each a small time slice (time quantum). This fast context switching creates the illusion that all tasks are running simultaneously, enabling interactive use and efficient CPU utilization.

  • Uses scheduling (often Round Robin) to allocate short time slices to each process.
  • Supports multiple users and interactive applications.
  • Improves responsiveness and resource utilization through multiprogramming.
  • Relies on context switching to alternate between processes quickly.
