Lessons 1 & 2

Local Area Networks

• One basic distinction between types of network is between Local Area Networks (LANs) and Wide Area Networks (WANs). A LAN is a self-contained network that spans a small area, such as a single building, floor, or room. In a LAN, all the nodes or hosts participating in the network are directly connected with cables or short-range wireless media. A LAN is typically a single site or possibly several sites in close proximity connected by high-speed backbones. 

• The term campus area network (CAN) is sometimes used for a LAN that spans multiple nearby buildings. Any network where the nodes are within about 1 or 2 km (or about 1 mile) of one another can be thought of as "local."
