英语翻译Data communications is the process of transmitting and r

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.
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 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.
