Conceptually, a thread context switch can be viewed as a process changing its state.
从概念上讲，一次线程上下文切换相当于进程改变它的状态。

在建立受信任连接之后，应用程序将用户切换到受信任上下文中定义的允许的用户。
Within each context, each author's interpretation of the term makes sense, but readers must make the switch between contexts on their own, which is often not easy.
