Unix Operating System use ________ Multitasking
The correct option is A Preemptive
Unix Operating System use
Preemptive Multitasking.
The term preemptive
multitasking is used to distinguish a multitasking operating system, which
permits preemption of tasks, from a cooperative multitasking system wherein
processes or tasks must be explicitly programmed to yield when they do not need
system resources.
Preemptive multitasking is
task in which a computer operating system uses some criteria to decide how long
to allocate to any one task before giving another task a turn to use the
operating system. The act of taking control of the operating system from one
task and giving it to another task is called preempting.
If a program is not using
the CPU, however, it can allow another program to use it temporarily. OS/2,
Windows 95, Windows NT, the Amiga operating system and UNIX use preemptive
multitasking, whereas Microsoft Windows 3.x and the MultiFinder (for Macintosh
computers) use cooperative multitasking.
