英语翻译
Data communications is the process of transmitting and receiving data in an orderly way so the data that arrives at its destination is an accurate duplication of the data that was sent.When data travels a short distance,such as when you send data from your computer to your printer,it is referred to as local communications.When data travels a long distance,the communication is referred to as telecommunications; the prefix “tele” is derived from a Greek word that means “far” or “far off.”
The difference between a short distance and a long distance is somewhat arbitrary (武断的).For example,if your computer sends data to a printer in the next room,it is regarded as local communications; if you phone the person in the next room,you are transmitting data over a telecommunications device.However,the same basic communications concepts apply to both local communications and telecommunications.
Basic data communications concepts are the building blocks for understanding how data travels on a communications system.These concepts come in handy (派得上用处) when you install,configure,or upgrade a local area network.In addition,these concepts help you set up modems,fax machines,and cellular data transfers.

数据通信是数据能有序地发送和接受的过程,并保证到达目的端的数据是发送端的一个精确的拷贝.
当数据在短距离传输时,例如,当你从你的PC发送数据到你的打印机时,就是一个本地通信.当数据在长距离传输时,这种通信就如电信.这个前缀”tele”源自于希腊语,”far”或”far off”.
明确判别短距离传输和远距离传输的区别某种程度上是主观臆断的.
举个例子,如果你的PC发送数据到另一个房间的打印机,这个过程可以被理解为本地传输；如果你打电话给另一个房间的人,你就是在通过电信设备传输数据(也就是可以被理解为远程传输了).
然而,运用于本地传输和电信时,通信概念的本义是一样的.
数据通信的本义是为了理解数据怎样在通信系统中传输的砌块.
这些概念在你安装、配置、或者更新一个局域网是是派得上用处的.
此外,这些概念也帮助你设置调制解调器、传真机和无线通信数据的传输.

信息传输是指信息以有序的方式进行传递和接收，从而使得原始信息完整，精确地复制并传递到目的地。当信息进行短距离传输时，例如信息由你的电脑传至打印机，称谓本地通信。当信息进行长距离传输时，我们称之为电信通信传输或远距离通信。其中的字母前缀“tele”源于古希腊单词意思为“远程/遥远”的意思。

信息传输是指信息以有序的方式进行传递和接收，从而使得原始信息完整，精确地复制并传递到目的地。当信息进行短距离传输时，例如信息由你的电脑传至打印机，称谓本地通信。当信息进行长距离传输时，我们称之为电信通信传输或远距离通信。其中的字母前缀“tele”源于古希腊单词意思为“远程/遥远”的意思。
关于本地通信与电信传输差异的界定是比较灵活的。例如电脑将信息传至隔壁房间的打印机，这就是进行的本地通信；如果你通过手机与隔壁房间的人通话，则这种信号传输则是通过电信设备进行的电信通信。但是总的来说，两者都是以基本的信息通信原理为基础的。
信息通信原理是我们了解信息如何在通信系统中传输的前提条件。当你进行本地局域网的安装，设置及升级的时候，就该它一显身手了。此外，信息通信原理也是我们进行modem，传真机包括手机通信设置所需要了解的。
