Local area networks (LANs) originated in the 1970s from the idea to interconnect relatively inexpensive but powerful desktop workstations since they provided low- cost computing capabilities . The basic drive for developing LANs was to link these computers with each other and with more expensive resources, such as high -quality printers, disk storage systems. Central files, and database. Today LANs are playing a major role in our lives both at work and at home. They have applications in every conceivable area where humans work and interact , including businesses, educational institutes research organization, medical facilities, government building, warehouse, and stock exchanges environments for voice LANs are used in home, office areas, stores, restaurants, and other environments for voice LANs are used i home office areas, stores, restaurants, and other environments for voice and data transfer among computing and communication devices, such as personal computers cordless telephones, a personal digital assistant computer games, and other portable devices.
Developers proposed a variety of technologies over the years, but only several continents managed to gain support. For example. An evolution of Ethernet , which was the first LAN architecture. It not only offers reliable service but owing to its widespread installations, users feel comfortable with its texture to new technology extensions to higher speeds and greater versatility. Ethernet evolved significantly at 10- Mbps hub-based architecture to a 10 Gbps switched technology using high performance twisted pair wires and optical fiber cables. In addition it is migrating from pure LAN use to transport of information within a metropolitan area (MAN)
