进程   进程模型     进程就是一个正在执行的程序的实例  值得注意的是,若一个程序运行了两遍,则算作两个进程 创建进程 在通用系统中,有四种主要事件导致进程的创建 ①系统的初始化 ②执行了 正在运行的进程 所调用的 进城创建系统调用 ③用户请求创建一个新进程 ④一个批处理作业的初始化  进程的状态 运行态(该时刻进程实际占用CPU) 就绪态(可运行,但因为其他进程正在运行而暂时停止) 阻塞态(除非某种外部事件发生,否则进程不能运行) 在Operating Systems Concept中还…

开始核心级线程 内核级线程对多核的支持怎么样? 和用户级相比,核心级线程有什么不同? ThreadCreate 是系统调用,内核管理TCB ,内核负责切换线程 如何让切换成型? − − 内核栈,TCB 用户栈是否还要用? 执行的代码仍然在用户态,还要进行函数调用 一个栈到一套栈:两个栈到两套栈 TCB 关联内核栈,那用户栈怎么办? 用户栈和内核栈之间的关联 所有中断( 时钟.外设.INT指令) 都引起上述切换 中断( 硬件) 又一次帮助了操作系统… 仍然是那个A() ,B() ,C() ,D()…

树的最小表示法 给定两个有根树的dfs序,问这两棵树是否同构 题解:http://blog.sina.com.cn/s/blog_a4c6b95201017tlz.html 题目要求判断两棵树是否是同构的,思路是用树的最小表示法去做.这里用的最小表示法就是将树的所有子树分别用1个字符串表示,要按字典序排序将他们依依连接起来.连接后如果两个字符串是一模一样的,那么他们必然是同构的.这样原问题就变成了子问题,子树又是一颗新的树. Source Code Problem: User: sdfzyhy…
