It shares with other threads belonging to the same process its code section, data section, and other operating-system resources, such as open files and signals.

the difference between a traditional single-threaded process and a multithreaded process.

An application typically is implemented as a separate process with several threads of control.

一个应用程序通常是作为一个单独的进程运行，同时由线程控制。

例如：

A word processor may have a thread for displaying graphics, another thread for responding to keystrokes from the user, and a third thread for performing spelling and grammar checking in the background.

一个文本处理器也许有一个线程复杂现实图形，另外一个线程对用户的键盘输入做出反应，还有第三个进程在后台负责检查语法。
