多程序和多线程之间的区别

1.多重编程：
多重编程是一次运行的多个进程，它通过组织作业(代码和数据)来提高CPU利用率，从而使CPU始终有一个要执行的进程。目的是在主存储器中保留多个作业。如果一个作业被输入/输出占用，则可以将CPU分配给其他作业。

2.多线程：
多线程是一种技术，可以在一个进程中创建多个线程以提高系统的计算速度。在多线程中，进程的许多线程是同时执行的，并且根据经济性来完成多线程中的进程创建。

多程序和多线程之间的区别：

S.No.	Multiprogramming	Multithreading
1.	The concurrent application of more than one program in the main memory is called as multiprogramming.	The process is divided into several different sub-processes called as threads, which has its own path of execution. This concept is called as multithreading.
2.	It takes more time to process the jobs.	It takes moderate amount of time for job processing.
3.	In this, one process is executed at a time.	In this, various components of the same process are being executed at a time.
4.	The number of users is one at a time.	The number of users usually one.
5.	Throughput is less.	Throughput is Moderate.
6.	Its efficiency is Less.	Its efficiency is moderate.
7.	It is economical.	It is economical.
