What are some Examples of time sharing operating system?

Answer 1

A special case of multiprogramming in which users access the computer through terminals, typically the devices with keyboards and screens. Dozens of users share the computer at once. The computer actually does not run them all simultaneously but it runs a small portion of ones user's job then moves the service to the next user providing service to each user several times and then it appears that is is actually doing all its actions at one time but it's not. After all the requests are done they all get responses about the same time.
