Multiprocessing in Operating System

Multiprocessing is a computing technique in which multiple processors or CPUs are used simultaneously to process more than one task at the same time. This technique is important for increasing the performance and efficiency of a computer system. Multiprocessing is mainly useful in situations where a large amount of data or multiple tasks need to be processed in parallel.

A multiprocessing system has more than one processor or core, which executes multiple tasks simultaneously. Each processor works independently, which increases the speed and efficiency of the system.

Symmetrical Multiprocessing (SMP): All processors share the same memory and operating system. All processors are equal and work independently with each other.

Asymmetrical Multiprocessing (AMP): There is one main processor that instructs other subordinate processors. The main processor performs primary tasks, while subordinate processors execute specific tasks.
