Networks did not just spring up overnight. Rather, it took years for scientists and engineers to advance this technology. The first networks were relatively simple, but now, we have networks that span the whole world, like the Internet!
LANs are one of the two types of networks. Usually, they connect computers within a few kilometers (or less) of each other and are found in homes or small office buildings.

Token Rings are less-popular alternatives to Ethernet.
WANs are usually comprised of two or more LANs. They can span large distances. The Internet, a type of WAN spans the whole world!
