Computer Communications: Bus Network
Bus Network, in computer science, a topology (configuration) for a local
area network in which all nodes are connected to a main communications line
(bus). On a bus network, each node monitors activity on the line. Messages are
detected by all nodes but are accepted only by the node(s) to which they are
addressed. Because a bus network relies on a common data "highway," a
malfunctioning node simply ceases to communicate; it doesn't disrupt operation
as it might on a ring network, in which messages are passed from one node to the
next. To avoid collisions that occur when two or more nodes try to use the line
at the same time, bus networks commonly rely on collision detection or Token
Passing to regulate traffic.Star NetworkStar Network, in computer science, a
local area network in which each device (node) is connected to a central
computer in a star-shaped configuration (topology); commonly, a network
consisting of a central computer (the......
