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)

用login二级目录的文件系统
这个程序是模拟采用二级目录结构的磁盘文件系统中的文件操作,它可以实现对文件的一些基本管理,如:读、写、删除文件等。通过这个程序可掌握文件子系统的原理,加深对二级目录结构的文件系统中用户管理、文件管理、目录管理的理解,并用程序实现对文件子系统的模拟。(the procedure is simulated using two disk directory structure of the file system file manipulation, it can be achieved on some basic document management, such as : read, write, delete files. Through this procedure can grasp the principle document subsystems to enhance the structure of the two file system user management, document management, directory management, understanding, and the procedures to achieve the right documents subsystem simulation.)
