MFC实现的，界面有好，实现了进程调度的算法 能够模拟操作系统的进程调度 适合初学者(MFC implementation, the interface is good, a process scheduling algorithm to achieve To simulate the operating system process scheduling for beginners)

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)

步进电机控制软件，可采用4、8、16、32、64、128细分，最大512细分(Stepper motor control software, can be used 4,8,16,32,64,128 subdivision, the largest 512 subdivision)

说明：  labview2018做的密码，主要实现控制系统登录，可以注册账号修改密码，密码成功进入主程序。(The password made by labview2018 is mainly used to log in the control system. You can register an account to change the password. The password successfully enters the main program.)

说明：  操作系统定时刷新功能，利用TIMER定时器定时后调用系统刷新功能，可做到计算机自动刷新、开机启动，并可设置刷新间隔时间并存档。(Operating system timing refresh function, using TIMER timer to call system refresh function after timing, can automatically refresh the computer, start, and set refresh interval time and archive.)
