Telecommunication is the sending of information in any form (example – Voice, data, tenet, and image) from places to another using electronic or light emitting media. However, all forms of telecommunications now rely on computers and computerized devices. It is a universal term that is used for a vast range of information-transmitting technologies such as mobile phones, landlines, VoIP and broadcast networks. Today, telecommunications are used to organize more or less remote computer systems into telecommunications networks.
Telecommunications devices include telephones, telegraph, radio, microwave communication arrangements, fibre optics, satellites and the Internet. On a smaller scale, examples include
- Corporate and academic wide-area networks (WANs)
- Telephone networks
