It was initially developed to meet the needs of integrated broadband services digital network, in the late 1980s and designed to combine telecommunications networks and computer networks. It was originally designed for use in public networks, but has now also been implemented as a major backbone technology for private networks. ATM uses asynchronous time-division multiplexing to encode and transfer data in the form of fixed-size cells or packets. It is normally used by Internet service providers on their private long-distance networks. It operates at the data link layer (Layer 2 in the OSI model) over fiber or twisted-pair cable. It uses a connection-oriented model where a virtual circuit must be established between two endpoints before the actual data exchange occurs. These virtual circuits can be dedicated connections, usually pre-configured by the service provider, or "switched", meaning they are set up per call via signaling and disconnected when the call ends. ATM is basically a cellular relay technology that divides higher level data units into 5...half of the sheet...most are sorted based on the network protocol standards in use today.
