短期和中期计划程序之间的区别

先决条件–流程计划程序

1.短期计划程序：
短期调度程序也称为CPU调度程序。其主要目的是根据某些设定标准来提高系统性能。短期调度程序有助于选择准备执行的进程组，并为每个进程分配CPU。与中期计划程序不同，它更频繁地执行，即在几秒钟内。短期调度程序对DOM(多程序程度)的控制较少。

2.中期排程器：
中期调度程序也称为交换调度程序。它的主要目的是从主内存中换出挂起的进程。如果正在运行的进程发出I / O请求，它将被挂起。暂停的过程不会显示完成方面的任何进展，因此应将其移至辅助存储，从而为新过程提供空间。与短期调度程序不同，它的执行不是很频繁。中期调度程序减少了DOM(多程序程度)。

短期和中期调度程序之间的区别：

S.No.	SHORT-TERM SCHEDULER	MIDDLE-TERM SCHEDULER
1.	Short-Term scheduler is also known as CPU Scheduler.	Middle-Term scheduler is also known as Swapping Scheduler.
2.	Speed of Short-Term scheduler is very fast as compared to middle-Term scheduler.	Its speed is less than Short-Term scheduler.
3.	It provides less control over Degree of programming.	It reduces the Degree of Programming.
4.	Its presence in Time sharing system is very minimal.	Middle-term scheduler is a part of Time sharing system.
5.	In short-term scheduler, there occurs transition of process from ready to executing state.	In middle-term scheduler, no process transition state occurs.
6.	Its function is to selects those processes which are ready to execute.	Its function is to reintroduce process back in the memory.
