Categories of networks Local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs) are the primary categories of networks. In addition to these three categories, hybrid networks are created using internetworking devices. Hybrid networks often combine the best characteristics of pure LAN, WAN, or MAN networks. LANs, WANs, and MANs differ in the way they are used and in the technologies
LAN- Local Area Network LANs connects microcomputers and other workstation devices located in a single office, a single building, or on a campus. The use of LANs allowed the sharing of resources, including hardware, software, and data. LAN characteristics include: •a common transmission medium throughout the network •bus, ring, or star topologies •lengths of less than 10 km •usually owned by their users •typical data rates of 10 Mbps (Megabits per second) , 100 Mbps, 1Gbps and 10 Gbps systems in development
