Multitasking/Multi programming operating system


Multitasking: - Multiprogramming is a fundamental form of parallel process in which several programs are run at the same time on a processor. In the case of a computer with a single CPU, only one task is said to be running at any point in time, meaning that the CPU is actively executing instructions for that task. Multitasking solves the problem by scheduling which task may be the one running at any given time, and when another waiting task gets a turn. The most commonly used personal computers usually run such OSs; include MS WINDOWS and the MACHINTOSH operating system.
