Virtual Private Network (VPN)
A VPN provides access to a private internal network over a public network such as the Internet. It uses tunneling protocols such as PPTP, L2TP, or SSTP.
Wide area network (WAN)
A network spanning a large physical area. Typically it is a group of two or more LANs connected from separate geographical locations. The connection between the LANs is almost always slower than the speed within the LANs themselves.
