Detailed explanation-1: -A wide area network (WAN) is a geographically distributed private telecommunications network that interconnects multiple local area networks (LANs). A LAN is a group of computers and network devices which are all connected to each other, typically from within a short relative geographical distance.
Detailed explanation-2: -In the case of a company that has a corporate headquarters and multiple branch offices scattered around the world, the WAN connects multiple LANs, While LANs typically connect end users through Ethernet technology, WANs can employ a variety of transport methods.
Detailed explanation-3: -Metropolitan area networks connect multiple LANs together through dedicated wired and wireless backbones. A MAN may use a local exchange carrier (LEC) to provide the connections between LANs and may connect to an internet exchange point for high-speed communication between the MAN and the public internet.
Detailed explanation-4: -WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other.
