Question	Answer
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.
