'''Multitasking''' [[operating system]]s are a subset of operating systems - now, by far the predominant form - which allow multiple programs to run at the same time. There are two principal types: '''preemptive''' multitasking, in which computations can be (unkownst to them) interrupted in the middle of their work to allow other computations to run, and '''cooperative''' multitasking, in which a running computation has to explicitly 'give up' the machine, in order for another computation to run.
