Networking refers to the technologies and techniques that enable the interconnection of devices and applications allowing them to communicate electronically.
Originally referring to local-area networks (LANs) designed to allow communication between computers in the same office or university, networking now covers a broad swathe of topics. To name but a handful:
- small-office/home-office
- campus/metro area networks (MANs)
- datacenters
- wide-area networks (WANs)
- optical networks
- telephone networks
- Voice over IP
- wireless LAN
- cellular telephony
