The network arrangement and data communication is given by logical topology.Token ring and token bus are the two logical topologies.A token passing mechanism is used in both token ring and token bus.100Base-FX, 100 Base SX and 100BaseBX and FDDI are types of fiber LAN.Single-attached station (SAS) and Dual-attached station (DAS) are the different types of FDDI stations.SAS is connected to the FDDI network through a single connector called S-port.Asynchronous Transfer Mode (ATM) network protocol converts data into a stream of fixed size cell before transmission.Apple Computers has designed a protocol suite known as Apple Talk.The network components of Apple Talk are sockets, nodes, network and zones.
Attached Resource Computer NETwork (ARCNET), the first LAN system and supports up to 255 nodes.The different types of devices used in ARCnet are, active hub, passive hub, ARCnet card and BNC terminator.
The most prominently used type of cabling for ARCnet are, coaxial cables, UTP and fiber optic.Point-to-point, distributed star, bus, daisy chain are the different topologies which are suitable for ARCnet.
