What do you understand about Multiprocessing and Multithreading in the context of Operating Systems? Differentiate between them.

Answer»
  • Multiprocessing: There are more than two processors in a multiprocessing system. The CPUs are added to the system to aid boost the system's computational speed. A CPU's registers and main memory are unique to it. However, because each CPU is independent, it is possible that one of them will be idle. One CPU may be idle while the other is overburdened with specific tasks. The PROCESS and resources are dynamically shared among the processors in this situation.
  • Multithreading: Multithreading is a system in which several threads of a process are established to increase the system's computational speed. Many threads of a process are PERFORMED simultaneously in multithreading, and process creation in multithreading is done economically.

The following table LISTS the differences between Multiprocessing and Multithreading:

MultiprocessingMultithreading
CPUs are added to increase computing power in multiprocessing. Multithreading, on the other hand, divides a single process into several threads to increase computational capability.
Multiprocessing is the execution of multiple processes at the same time.Many threads of a process are executed at the same time in multithreading.
Multiprocessing is divided into two TYPES: symmetric and asymmetric.Multithreading, on the other hand, is not classified in any of the categories.
Procedure creation is a time-consuming process in multiprocessing.In Multithreading, thread creation is economical.
Each process under multiprocessing has its own address space.When using multithreading, all threads share a COMMON address space.
