DOS - ç ，它的内核也是FreeDOS的内核。并在此基础上进行了一定的修改，使其更加实用。 FreeDOS的是项目设计 提供替代到MS - DOS，PC的DOS的和DR - DOS的自由 。-DOS-C started in 1988 as an experiment in writing device drivers in C for Microsoft s MS-DOS. Both block and character device drivers were written, along with special C data structures to match the MS-DOS request packet. It was then recognized that using the same techniques, an operating system could be written that would take advantage of the C language features and would require much less time to develop than the traditional assembly language techniques. Although UNIX had proven this earlier, it was not tried with a traditional pc operating system. At this time, a minimal operating system using the device drivers written earlier along with a new 8086 interrupt API was developed. It was called XDOS and proved to be a functional operating system. This new operating system was used to develop booting techniques and a C library SDK was dev

线程同步机制。 互斥器的功能和临界区域很相似。区别是：Mutex所花费的时间比Critical Section多的多，但是Mutex是核心对象(Event、Semaphore也是)，可以跨进程使用，而且等待一个被锁住的Mutex可以设定TIMEOUT，不会像Critical Section那样无法得知临界区域的情况，而一直死等。-Thread synchronization mechanism. Mutex" s function and the critical region is very similar. The difference is: Mutex spent more time than the multi-Critical Section, but the Mutex is the core object (Event, Semaphore is), you can cross-process use, and has been locked waiting for a Mutex can be set to TIMEOUT, not as Critical Section did not know the critical situation in the region, for so long and so die.

模拟内存换页算法，包括FIFO（先进先出first in first out）,OPT(动态分配optimal),LRU(最近不使用latest use recently),LFR(最近最低频率lowest frequency recently),NUR(最近不使用no used recently）-Analog memory paging algorithms, including FIFO (first in first out first in first out), OPT (dynamic allocation optimal), LRU (recently does not use latest use recently), LFR (the lowest frequency of the recent lowest frequency recently), NUR (do not use the recent no used recently)

职工信息包括职工号、姓名、性别、年龄、学历、工资、住址、电话等（职工号不重复）。试设计一职工信息管理系统，使之能提供以下功能： （1）系统以菜单方式工作； （2）职工信息录入功能（职工信息用文件保存）； （3）职工信息浏览功能； （4）职工信息查询功能，查询方式：按学历、职工号查询等； （5）职工信息删除、修改功能。 -Information including the number of workers union, name, sex, age, education, salaries, addresses, telephone numbers, etc. (number of workers of non-repetition). Workers try to design a management information system so that it can provide the following functions: (1) the way the menu system to work (2) staff input function information (information workers saved documents) (3) staff information browsing (4) Information trade unions function, query methods: according to their academic qualifications, trade unions, such as its inquiries (5) information workers to delete, modify function.
