Telecommunications is a general term for a vast array of technologies that send information over distances. Mobile phones, land lines, satellite phones and voice over Internet protocol (VoIP) are all telephony technologies -- just one field of telecommunications. Radio, television and networks are a few more examples of telecommunication.
Telephony is a term denoting the technology that allows people to have long distance voice communication. It comes from the word âtelephoneâ which, in turn, is derived from the two greek words tele which means far and phone which means speak, hence the idea of speaking from far. The termâs scope has been broadened with the advent of the different new communication technologies.
