Telecommunications and Networks (Repost)

Telecommunications is an old and stable technology if you think only of telephones and telegraph. But in the 1960s came computers and the processing of data. Soon, we needed data communications to transmit data to remote PCs connected by networks. Later, these points of communications increased in number, with the transmission being no longer limited to data but included text, voice and even images and video.
This book explains in clear and simple language the development of this technology, the management of telecommunications and the many applications that are now possible because of telecommunications.
