Techopedia Explains Computer Networking

A router, network card and protocols are the essential pillars upon which any network is built. Computer networks are the backbone of modern-day communication. Even public switched telephone networks are controlled by computer systems; most telephonic services are also working with IP.

The increasing scope of communication has led to much advancement in the networking field and in its relative industries like hardware, software manufacturing and integration. As a result, most households have access to one or more networks. There are three broad network types:

  • Local Area Network (LAN): Used to serve a small number of people located in a small geographical space. Peer-to-peer or client server networking methods can be employed.
  • Wide Area Network (WAN): Formed to connect a computer with its peripheral resources across a large geographical area.
  • Wireless Local Area Network (WLAN)/Wireless Wide Area Network (WWAN): Formed without the use of wires or physical media to connect hosts with the server. The data is transferred over radio transceivers.
