随着社会的快速发展,生活水平的不断提高,出于对智能化技术发展要求,为用户提供方便,操作简单,快捷,可靠的服务,开发了银行帐户管理系统.-With the rapid development of society, the standard of living continues to improve, based on the requirements of the development of intelligent technology. to provide users with convenient, simple, fast, reliable service and the development of the bank account management system.

操作系统课程设计设计文档题目一的内容实现UP、DOWN原语产生3个进程：两个进程模拟需要进入临界区的用户进程。当需要进入临界区时，显示：“进程x请求进入临界区…”，同时向管理进程提出申请；申请返回，表示进入了临界区。在临界区中等待一段随机时间，并显示：“进程x正在临界区…”；当时间结束，显示：“进程x退出临界区…”,同时向管理进程提出退出申请；当申请返回，显示：“进程x已退出临界区。”一个进程作为原语的管理进程，接受其他进程的临界区进入请求：如果允许进入，则根据DOWN 原语的操作步骤设置相应变量，然后返回； 如果不允许进入，则进入循环等待，直到允许为止； 退出时模拟UP 操作。 进程间通信可以采用信号、消息传递、管道或网络通信方式。-Operating system design documents subject curriculum design content of the UP, DOWN primitives have three process

WINDOS2000下不需要弹出对话框，直接自动关机或者重新启动-WINDOS2000 pop-up dialog box under no direct automatic shutdown or restart

用VB实现生产者与消费者问题-VB producer and consumer issues

本次程序的题目为：进程管理――支持多个进程并发运行的简单的进程管理模拟系统，对本实验的分析要求是：⑴系统中的同步机构采用信号量上的P、V操作的机制；⑵控制机构包括阻塞和唤醒操作；⑶时间片中断处理程序处理模拟的时间片中断；⑷进程调度程序负责为各进程分配处理机；⑸根据用户的需求来创建n个进程(n为即满足用户需求,又不超出系统可容的最大进程数),各进程互斥地访问使用临界资源 S1、S2；⑹使用动态优先数(如：随阻塞次数的增加而减小优先数，以提高其优先权)；⑺进程结束后应能够撤消；⑻进程间能实现“发送”和“接收”两个消息缓冲通信操作；⑼系统在运行过程中随机打印出各进程的状态变换过程、系统的调度过程及公共变量的变化情况，在一个进程运行完毕，进入完成状态后，可以将该进程撤消，也可以动态的创建另一个新的进程。-the procedures on the topic of : process management-- to support multiple concurrent processes running a simple process management simulation system for the analysis of the experimental requirements are : 1 system of institutions using synchronous signals on the amount of P, V operation of the mechanism; 2 control agencies, including obstruction and awaken operation ; 3-time interrupt handling procedures-time simulation of interruption; 4 process scheduler is responsible for the allocation process processors; together according to the user"s needs to create process n (n that meet user needs, without exceeding the system can accommodate

《自己动手写操作系统》一书里面的源码，个人认为对学习操作系统的朋友有点帮助。-"to write his own operating system," a book which the source code, personal view on learning the system a bit to help a friend.

是操作系统的置换算法，主要用于操作系统的阻塞与执行还有就绪-Operating system replacement algorithm is mainly used for blocking the implementation of the operating system still in place

我自己写的一个实模式的操作系统，支持fat12文件系统和一个和shell整合到一起的简单的键盘驱动，目前正在实现pci总线驱动程序。以后将会转入到保护模式下开发-I wrote it myself a real mode of the operating system, support FAT12 file system and a shell and the integration with a simple keyboard-driven, are currently achieving pci bus driver. After that it will enter a protected mode development
