操作系统学习中的模拟CUP如何调度外部进程的算法—优先度调用算法(Analog CUP in the operating system, learn how to schedule external process algorithm- priority call algorithm)

1．虚拟存储器的引入 局部性原理：程序在执行时在一较短时间内仅限于某个部分；相应的，它所访问的存储空间也局限于某个区域，它主要表现在以下两个方面：时间局限性和空间局限性。 2．虚拟存储器的定义 虚拟存储器是只具有请求调入功能和置换功能，能从逻辑上对内存容量进行扩充的一种存储器系统 (1. The introduction of virtual memory locality principle: program execution in a relatively short period of time limited to a particular part of it Accordingly, it has access to the storage space is also limited to a particular region, it is mainly manifested in the following two aspects: the time limitations and space limitations. 2. The definition of virtual memory Virtual memory is just a request for redeployment of functions and displacement functions, from the logical to expand the memory capacity of a memory system)

说明：  操作系统提供一系列服务： 多任务、用户界面、内存管理、内存保护、 文件存取、网络、设备控制、硬件控制 、错误检测及恢复系统、安全(The operating system provides a range of services: Multitasking, user interface, memory management, memory protection, File access, network, device control, hardware control, error detection and recovery systems, security)
