| Question | Answer |
| LAN | Local-area-network High-speed transmissions over a restricted geographical area. Signals need to be boosted if the LAN is too large. |
| WAN | Wide-area-network Used to link LANs separated by large distances, from tens of meters to thousands of kilometers. |
| PAN | Personal-area-network A computer network organised around an individual person, often involving mobile computers and smartphones. |
| VPN | Virtual-private-network Cheaper than WAN, VPN uses dedicated packet-switched links to interconnect two or more LANs, creating a VPN that interconnects several LANs by using the existing internet infrastructure. |
