Briefly compare a WAN to a LAN and explain how to differentiate LANs from one another.
What will be an ideal response?
A WAN is nothing more than a group of two or more interconnected LANs. For a WAN to work, each LAN needs some form of unique identifier called a network ID. To differentiate LANs from one another, each computer on a single LAN must share a very similar, but not identical, IP address. Some parts of the IP address will match all the others on the LAN.
