The sign on the bus read "Private: Not In Service."

公共汽车上的标志写着“私人所有：不运营。”

The service bus subsystem automatically provided for both types of interaction, given that it was purely message based and supported a read method that could wait for an incoming message.

如果服务总线子系统是纯粹基于消息的，而且支持某种用来等待传入消息的读取方法，它将自动提供这两种类型的交互。

For example, we wouldn't want ordinary user-level code to gain access to the system bus and directly read internal communication.

例如，我们不希望普通用户级别的代码能够访问系统总线以及直接读取内部通信。

For example, you wouldn't want ordinary user-level code to be able to gain access to the system bus and directly read internal communication.

例如，不希望普通用户级代码能够访问系统总线以及直接读取内部通信。

As you read through this series, you may find it useful to refer to the outline of the Bus architecture in Figure 1.

读过这个系列后，您也许会发现参见图1中的总线体系结构是有用处的。
