Description: 看一下UNIX系统中的进程和Mach的任务和线程之间的关系。在UNIX系统中，一个进程包括一个可执行的程序和一系列的资源，例如文件描述符表和地址空间。在Mach中，一个任务仅包括一系列的资源；线程处理所有的可执行代码。一个Mach的任务可以有任意数目的线程和它相关，同时每个线程必须和某个任务相关。和某一个给定的任务相关的所有线程都共享任务的资源。这样，一个线程就是一个程序计数器、一个堆栈和一系列的寄存器。所有需要使用的数据结构都属于任务。一个UNIX系统中的进程在Mach中对应于一个任务和一个单独的线程。

In UNIX systems, a process includes an executable program and a range of resources, such as file descriptors table and address space. In Mach, a task only a series of resources; Threads handle all the executable code. A Mach task can have any number of threads and its associated, and each one must thread related tasks. And to a certain set of tasks related to the threads are sharing all the resources. Thus, a thread is a program counter, a stack, and a series of registers. All need to use the data structures are covered by the mandate. A UNIX system in the process of Mach which corresponds to a mandate and a separate thread.

Description: 线程的同步
虽然多线程能给我们带来好处，但是也有不少问题需要解决。例如，对于像磁盘驱动器这样独占性系统资源，由于线程可以执行进程的任何代码段，且线程的运行是由系统调度自动完成的，具有一定的不确定性，因此就有可能出现两个线程同时对磁盘驱动器进行操作，从而出现操作错误；又例如，对于银行系统的计算机来说，可能使用一个线程来更新其用户数据库，而用另外一个线程来读取数据库以响应储户的需要，极有可能读数据库的线程读取的是未完全更新的数据库，因为可能在读的时候只有一部分数据被更新过。-thread synchronization Although multithreading can bring us benefits, but there a lso many problems to be solved. For example, as disk drives such exclusivity system resources and can thread the process of implementation of any code, and the thread running by the scheduling system automatically and to a certain extent the uncertainty, So, then there could be two threads while the disk drives operate, which have operational errors; For example, For the computer banking system, may use a thread to update users of its database, and use another thread to read a database to respond to the needs of depositors, Reading is very likely to read threads database is not fully update the database, Reading may be because the time was only part of the updated data.

Description: 8. MFC的进程和线程
1. Win32的进程和线程概念
进程是一个可执行的程序，由私有虚拟地址空间、代码、数据和其他操作系统资源（如进程创建的文件、管道、同步对象等）组成。一个应用程序可以有一个或多个进程，一个进程可以有一个或多个线程，其中一个是主线程。
线程是操作系统分时调度分配CPU时间的基本实体。一个线程可以执行程序的任意部分的代码，即使这部分代码被另一个线程并发地执行；一个进程的所有线程共享它的虚拟地址空间、全局变量和操作系统资源。
之所以有线程这个概念，是因为以线程而不是进程为调度对象效率更高：
• 由于创建新进程必须加载代码，而线程要执行的代码已经被映射到进程的地址空间，所以创建、执行线程的速度比进程更快。
• 一个进程的所有线程共享进程的地址空间和全局变量，所以简化了线程之间的通讯。
