Telecommunication has become an important part of our daily life and deeply effects modern society.Generally telecommunication is the transmiion(传送)of signals over a distance for the purpose of sending information.By sharing information, people can get such a development today.Information is even considered to be a standard criteria(评判准则,尺度)to ae life quality of a man.Telecommunication is now understood as a system consists of three elements: a transmitter(发射机,传送者)that takes
information and converts(使转变)it to a signal;a transmiion that carries the signal;and a receiver that receives the signal and converts it back into usable information.Some other
telecommunication systems such as mobile phones, computers in net work act as both a transmitter and receiver or transceiver.In earlier times telecommunication was done slowly by mean of simple methods such as the use of smoke signals, and
semaphore(打旗语), and usually could transfer a bit of information.For a longer distance and more detail maage, pigeon post was
used.People wrote letters and pigeons carried them to others.Since the electronics was established and applied in
communication, telecommunication has made a great advance
toward all the fields of life today.Step into the Information Age(信息时代),our communication depends on the mobile telephones and internet.Advatages
