| WAN (Wide Area Networks) | WANs are used to link LANs that are separated by large distances ranging from a few ten of metres to thousands of kilometres. |
| LAN (Local Area Networks) | LANs are characterised by high-speed transmission over a restricted area. Signals need to be boosted if the LAN is too large. |
| VPN (Virtual Private Networks) | VPNs are a cheaper alternative to a WAN and use dedicated packet-switched links to interconnect two or more LANs. Several LANs are interconnected by using the existing internet infrastructure. |
| PAN (Person Area Networks) | PAN is a computer network organised around an individual person. PANs can involve smartphones and mobile computers. |
