此为操作系统实验报告:处理器调度 内含:程序流程图 设计目的与思路 主要源码等. 简介:在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。当就绪状态进程个数大于处理器数时，就必须依照某种策略来决定哪些进程优先占用处理器。本实验模拟在单处理器情况下处理器调度，帮助学生加深了解处理器调度的工作。-experimental operating system for this report : Processor Scheduling consisting of : flowchart designed and ideas such as major source. Introduction : the introduction of multi-channel programming system, often there are a number of processes at the same time readiness. When the readiness of the process is greater than the number when the number of processors, it must, in accordance with a strategy to determine which process priority processor. Experimental simulation of the processor in a single processor scheduling circumstances, to help students better understand processor scheduling work.

如果对Windows开发有什么问题的话，请翻阅PetZold的著作吧。在《Window程序设计》（第5版）中，这位杰出的“Windows先锋 奖”（Windows Pioneer Award）获得者根据最新的Windows操作系统权威技术修订了他的经典著作――再一次演示了基本的Win32程 序设计的API核心内容。本书的内容包括： ** 基本内容――输入、输出和对话框 ** Unicode概述 ** 图形――绘图、文本和字体、位 图和元文件 ** 内核和打印机 ** 声音和音乐 ** 动态链接库 ** 多任务和多线程 ** 多文档界面 ** Internet和 Intranet的程序设计 其中采用的大多是具有代表性的示例，这本Petzold著作为使用 Windows 95、Windows 98或 Windows NT的各级windows程序员提 供了最基本的参考和指导。没有经验的开发人员也可以从中获取大量的新知识。 -err
