多处理和多线程之间的区别

多处理和多线程都用于增加系统的计算能力。

多处理：
多处理是具有一个或两个以上处理器的系统。在多处理中，增加了 CPU 以提高系统的计算速度。由于多处理，有许多进程同时执行。多处理分为两类：

1. Symmetric Multiprocessing
2. Asymmetric Multiprocessing 

多线程：
多线程是在一个进程中创建多个线程以提高系统计算速度的系统。在多线程中，一个进程的多个线程同时执行，多线程中的进程创建是根据经济性来完成的。

多处理和多线程的区别：

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.
