Q1. What is Process Management?
Ans. A batch system executes jobs, whereas a time-shared system has user programs, or tasks. Even on a single-user system such as Microsoft Windows, a user may be able to run several programs at one time: a word processor, a web browser, and e-mail package. Even if the user can execute only one program at a time the operating system may need to support its own internal programs activities, such as memory management. In many respects, all these activities are similar, so we call all of them processes.
