Difference between Multiprocessing and Multithreading

Both Multiprocessing and Multithreading are used to increase the computing power of a system. Multiprocessing: Multiprocessing is a system that has more than one or two processors. In Multiprocessing, CPUs are added for increasing computing speed of the system. Because of Multiprocessing, There are many processes are executed simultaneously. Multiprocessing are classified into two categories:

1. Symmetric Multiprocessing
2. Asymmetric Multiprocessing 

Multithreading: Multithreading is a system in which multiple threads are created of a process for increasing the computing speed of the system. In multithreading, many threads of a process are executed simultaneously and process creation in multithreading is done according to economical. 

Difference between Multiprocessing and Multithreading:

S.NO	Multiprocessing	Multithreading
1.	In Multiprocessing, CPUs are added for increasing computing power.	While In Multithreading, many threads are created of a single process for increasing computing power.
2.	In Multiprocessing, Many processes are executed simultaneously.	While in multithreading, many threads of a process are executed simultaneously.
3.	Multiprocessing are classified into Symmetric and Asymmetric.	While Multithreading is not classified in any categories.
4.	In Multiprocessing, Process creation is a time-consuming process.	While in Multithreading, process creation is according to economical.
5.	In Multiprocessing, every process owned a separate address space.	While in Multithreading, a common address space is shared by all the threads.
