Local area network architecture is categorized as either peer-to-peer or client-server. On a client-server local area network, multiple client-devices are connected to a central server, in which application access, device access, file storage, and network traffic are managed.

Applications running on the Local Area Network server provide services such as database access, document sharing, email, and printing. Devices on a peer-to-peer local area network share data directly to a switch or router without the use of a central server. LANs can interconnect with other LANs via leased lines and services, or across the Internet using virtual, private network technologies.

Local Area and Wide Area Networks differ in their range. The first step in Local Area Network design is determining network needs. Before building a Local Area Network, identify the number of devices, which determines the number of ports required. A switch can extend the number of ports as the number of devices increases. In order to connect devices wirelessly, a router is required to broadcast a wireless LAN. A LAN might serve an office, a floor of a building, and entire building, or a campus area, but generally does not cross a public right-ofway such as a street.

The distance limitation generally is in the range of a few kilometers, at most, although that is sensitive to the transmission media employed, which include coaxial cable, twisted pair, optical fiber, infrared IR light, and radio frequency RF systems.

Raw bandwidth ranges up to 10 Gbps, although actual throughput generally is much less. LANs generally are private networks, although public wireless hotspots offering wireless Internet access currently are popular.
