[OS Develop] bochs-2.2.1.win32-src DL : 0: Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 and 3DNow! instructions. Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows 95/98 and Windows NT/2000. Bochs was written by Kevin Lawton and is currently maintained by the Bochs project at \"http://bochs.sourceforge.net\".

[OS Develop] textedit DL : 0: 操作说明该程序除源程序外，还需有另外一个存放记录的文件（此程序中使用的文件名为score.txt），本程序并没有创建这个文件的功能，要首先产生这个文件，可用记事本先作一个空的文件名为score.txt 的文件。程序运行与该文件的存放位置有关，位置是程序数据段的FNAME的值。二者要保持一致，否则会出错。程序运行时，在出现主菜单后，按l键，将显示学生的各科成绩；按i键后，执行插入功能，可以插入新的学生成绩；按m键，可修改学生成绩。由于本程序是个简单程序，在修改时，要输入学生的所有成绩，包括不要修改的成绩；按d键输入要删除的学生名，将使其成绩全为0；按q键输入要查询的学生的姓名，将显示其各可成绩；按c键将显示数学成绩的分段统计结果。以上功能在单独运行时可以实现（即在进入主菜单后，单击功能键选中该功能操作后关闭。运行其它功能，要重新进入主菜单单击别的功能键，即每次只能运行一项功能）。要特别说明的是，本程序主要目的是验证汇编程序实现的数据记录操作功能，为使程序不致过长，减少篇幅，程序处理都很简单。程序中没有错误处理程序，如果输入错误，如按退格键将会出错，因此输入时要注意不要输错。 -Operating Instructions In addition to the program source code, the need to have another record store file (the file used in this program called score.txt), this procedure does not create the file function, to first generate the file, use Notepad first as an empty file named score.txt file.

[OS Develop] OS_1_1 DL : 0: 进程调度算法的模拟 1．用语言来实现对n个进程采用不同调度算法的进程调度。 2．每个用来标识进程的进程控制块PCB用结构来描述，包括以下字段：（1）进程标识ID，其中0为闲逛进程，用户进程的标识数为1，2，3…。（2）进程优先级Priority，闲逛进程（idle）的优先级为0，用户进程的优先级大于0，且随机产生，优先数越大，优先级越高。（3）进程占用的CPU时间CPUtime，进程每运行一次，累计值等于4。（4）进程总共需要运行时间Alltime，利用随机函数产生。（5）进程状态，0：就绪态；1：运行态；2：阻塞态。（6）队列指针next，用来将多个进程控制块PCB链接为队列。 3．优先数改变的原则（1）进程在就绪队列中每呆一个时间片，优先数增加1。（2）进程每运行一个时间片，优先数减3。 4．在调度前，系统中拥有的进程数PCB_number由键盘输入，经初始化后，所有的进程控制块PCB链接成就绪队列。先到先服务优先级轮转法最短作业优先 -Process scheduling simulation 1. Use language to achieve the n processes using different scheduling process scheduling. 2. The process used to identify each process control block PCB used to describe the structure, including the following fields: (1) process identification ID, where 0 is the process of wandering, the identity of the user process number 1, 2, .... (2) process priority Priority, wandering process (idle) priority is 0, the user process priority greater than 0, and randomly generated, the greater the priority number, the higher the priority. (3) process CPU time CPUtime, each process runs once, the cumulative value equal to 4. (4) process requires a total running time Alltime, using random function generator. (5), process status, 0: Ready state 1: Run the state 2: blocking state. (6) queue pointer next, is used to link multiple process control block PCB for the queue. 3.

[OS Develop] rr DL : 0: 时间片轮转调度是一种最古老，最简单，最公平且使用最广的算法。每个进程被分配一个时间段，称作它的时间片，即该进程允许运行的时间。如果在时间片结束时进程还在运行，则CPU将被剥夺并分配给另一个进程。如果进程在时间片结束前阻塞或结束，则CPU当即进行切换。调度程序所要做的就是维护一张就绪进程列表，当进程用完它的时间片后，它被移到队列的末尾。-CPU will be denied and assigned to another process. If the process before the end of the time slice blocking or over, immediately switch the CPU. Scheduler to do is to maintain a ready list of processes, when the process runs out of its time slice, it was moved to the end of the queue.

[OS Develop] Linux_Shell_Scripting_With_Bash DL : 1: A shell is a program that runs operating system commands.Using a conventional desktop, the user selects an item with the mouse and then applies an action to it,such as highlighting an icon and choosing to copy it.In a shell,the person types instructions (or actions) followed by the targets and any special options.This counterintuitive interface can confuse new users who are used to conventional desktops.
