Its function is to absorb signals on the line, thereby keeping them from bouncing back and being received again by the network. Token - A special packet that contains data and acts as a messenger or carrier between each computer and device on a ring topology. Each computer must wait for the messenger to stop at its node before it can send data over the network. Usually uses a star-wired ring topology. The physical topology of a network refers to the configuration of cables, computers, and other peripherals.
Logical topology is the method used to pass the information between workstations.
In networks, it is generally used to allow for the connection between two different types of cable connectors, such as AUI and RJ-45. Tree Topology - LAN topology similar to linear bus topology, except that tree networks can contain branches with multiple nodes. Twisted Pair - Network cabling that consists of four pairs of wires that are manufactured with the wires twisted to certain specifications. Available in shielded and unshielded versions. A network connecting computers within very large areas, such as states, countries, and the world.
