The scheduler maintains a record of the processes present in the computer system,introduces new processes to this pool,and remove completed processes from the pool.Thus when a user requests the execution of an application.it is the adds the scheduler that adds the execution of that applocation to the pool of current processes.To keep track of all the processes,the scheduler maintains a block of information in main memory called the process table.Each time the execution of a program is requested,the scheduler creates a new entry for that process in the process table.This entry contains such information as the memory area assigned to the process,the priority of the process ,and whether the process is ready or waiting.A process is ready if it is in a state in which its progress can continue;it is waiting if its progress is currently delayed until some external event occurs,such as the completion of a disk access,the pressing of a key at the keyboard,or the arrival of a message from another process.

调度程序会在计算机系统中记录一个当前进程,引进新的进程到这个池中,并且完全的从池删除进程.因此,当一个用户请求执行一个应用程序.它会增加执行该应用程序的当前进程池的调度.为了保持跟踪所有进程,调度程序会在一段内存中保留调用的信息被称为进程表.每一次执行一个程序请求,调度程序会在进程表中为当前进程创建了一个新条目.该条目包含了该进程在内存区域中分配该进程的内存区域,进程的优先级等信息,以及该进程是否已准备就绪或是等待.一个进程当它处于可以继续的状态下就是准备就绪,如果它正在推迟到一些外部事件发生时才继续,它就是处于等待的状态,例如完成磁盘的访问,在键盘上按下一个键,或者另一个进程的消息到来.
