电信有助于在一定距离上传输信号以进行通信。 在早期,这可能涉及使用烟雾信号,鼓,标语,旗帜或镜子闪光。 从电报开始,电信通常涉及使用电子发射器,例如电话,电视,无线电,光纤和计算机。

Telecommunications helps to transmit signals over a distance for communication. In the early days, this may involve using smoke signals, drums, slogans, flags or mirror flashes. Starting with telegrams, telecommunications typically involve the use of electronic transmitters such as telephones, televisions, radios, fiber optics and computers.
