LAN and WAN. It sounds like a progressive band name. While they were progressive in their time, LAN and WAN is not a band name but area networks of connected computers. Nearly everyone who has interacted with a computer has accessed a LAN, and most people have encountered a WAN without even realizing it.
A LAN is a local area network and connects network devices over a relatively short distance. They can typically be found in office buildings, schools, and homes. As the term implies, a wide area network or WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth. A common interaction with WAN's is through bank ATM's.
