在网络工程通讯系统中,计算机及网络设备之间需要传输介质来进行信息与数据的联接与传递。假设将网络上钩算机比作货站,而数据信息是汽车的话,那么,网络传输介质便是不可缺少的公路。现在计算机数据通讯的传输介质包含有线介质(双绞线、铜轴电缆、光纤)和无线介质(无线电波、红外线和微波)两种,

(In the network engineering communication system, a transmission medium is required between the computer and the network equipment for the connection and transmission of information and data. Assuming that the computer hooked on the network is compared to a freight station, and the data information is a car, then the network transmission medium is an indispensable road. At present, the transmission medium of computer data communication includes wired medium (twisted pair, copper coaxial cable, optical fiber) and wireless medium (radio wave, infrared and microwave).)
