local area network

A local area network (LAN) is a computer network covering a small local area, like a home, office, or small group of buildings such as a home, office, or college.

A local area network (LAN) is a system for linking private telecommunications equipment, as in a building or cluster of buildings.

A computer network covering a small geographic area, like a home, office, or group of buildings. The defining characteristics of LANs, in contrast to Wide Area Networks (WANs), include their much higher data transfer rates, smaller geographic range, and lack of a need for leased telecommunication lines 

• Storage Area Networks — Separate network handling storage needs — Detaches storage tasks from specific servers — Shared storage facility across high-speed network — Hard disks, tape libraries, CD arrays — Improved client-server storage access — Direct storage to storage communication for backup

• High speed office networks — Desktop image processing — High capacity local storage

• Backbone LANs — Interconnect low speed local LANs — Reliability — Capacity — Cost
