What does it mean for an operating system to support multitasking? How is multitasking different from time sharing?
What will be an ideal response?
Multitasking is where a single user can have multiple programs executing simultaneously. On a single processor computer, this is accomplished by the operating system which quickly switches control of the CPU between programs. Time sharing is similar to multitasking, except that the programs sharing the computer belong to different users. In a sense, multiple users share the CPU via time sharing.
