If this is a computer related question; a WAN is a Wide Area Network. If you have 2 or more computers in your home or business and they are connected to each other you have a network. This is considered a local area network - LAN.
If you have 2 of these groups of computers in separate locations they are each individual LANs. When you connect the separate LANs together either with dedicated phone lines (like T1) or through the internet using a 'private' (VPN is one type) connection they become a WAN.
