6 CLIENT/SERVER AND PEER-TO-PEER NETWORKING Networks generally fall into one of two broad network categories: Client/server networks Peer-to-peer networks

9 Networks Local Area Networks (LANs) A local area network (LAN) is a group of computers and network communication devices interconnected within a geographically limited area, such as a building or a campus. LANs are characterized by the following: They transfer data at high speeds (higher bandwidth). They exist in a limited geographical area. Connectivity and resources, especially the transmission media, usually are managed by the company running the LAN.

10 Networks Wide Area Network (WAN). A WAN can be located entirely within a state or a country, or it can be interconnected around the world. WANs are characterized by the following: They exist in an unlimited geographical area. They usually interconnect multiple LANs. They often transfer data at lower speeds (lower bandwidth). Connectivity and resources, especially the transmission media, usually are managed by a third-party carrier such as a telephone or cable company

11 INTRANETS AND INTERNETS Intranet describes an internetwork of computers on a LAN for a single organization Internet describes the network of computers you can connect to using a browser—essentially, an internetwork of LANs available to the public.
