What are the essential properties of time sharing in OS?

Time sharing in operating systems allows multiple users to interact with a computer simultaneously by allocating a small time slice for each user’s process. This approach ensures responsiveness and efficient CPU utilization by quickly switching between tasks, giving the illusion of parallelism. Essential properties include process scheduling, where the OS manages the order and duration of execution; context switching, which saves and restores the state of processes; and user interactivity, enabling real-time user engagement with applications. Overall, time sharing enhances system efficiency and user experience by maximizing resource utilization.
