[单选题]● 建筑物综合布线系统中的工作区子系统是指（66）。（66）

由终端到信息插座之间的连线系统

解析：解析：工作区子系统由终端设备连接到信息插座的连线(软线)组成。它包括装配软线、连接件和连接所需的扩展软线，并在终端设备和输入/输出(I/O)之间搭接，相当于电话配线系统中连接话机的用户线及话机终端部分。在智能大厦综合布线系统中，工作区常用术语服务区(coveragearea)替代，通常服务区大于工作区。

[单选题]In information theory, "information" is regarded as knowledge which reduces or removes(71) about the occurrence of a specific event from a given set of possible events. The concept "event" is to be understood as used in the theory of probability. For instance, an event may be the occurrence of a(72) character or word in a given message or in a given position of a message.In communication theory, channel is defined as that part of a communication system that connects the message source with the message sink. An encoder may be inserted between the message source and the input to the channel, and a(73) between the output of the channel and the message sink. Generally, these two units are not considered as being parts of the channel. In certain cases, however, they may be considered as pans of the message source and message sink,(74) In information theory(75) to Shannon, the channel can be characterized by the set of conditional probabilities of occurrence of all the messages received at the message sink when a given message emanates from the message source.
