"Bus: all stations attach, through appropriate hardware interfacing known as a tap, directly to a linear transmission medium, or bus. Full-duplex operation between the station and the tap allows data to be transmitted onto the bus and received from the bus. A transmission from any station propagates the length of the medium in both directions and can be received by all other stations. At each end of the bus is a terminator, which absorbs any signal, removing it from the bus. Tree: a generalization of the bus topology. The transmission medium is a branching cable with no closed loops. The tree layout begins at a point known as the headend. One or more cables start at the headend, and each of these may have branches. The branches in turn may have additional branches to allow quite complex layouts. Again, a transmission from any station propagates throughout the medium and can be received by all other stations. Ring: the network consists of a set of repeaters joined by point-to-point links in a closed loop. Each station attaches to the network at a repeater and can transmit data onto the network through the repeater. Star: each station is directly connected to a common central node. Typically, each station attaches to a central node via two point-to-point links, one for transmission and one for reception."

Jalopy topology Within local area cpa networks where bus topology is utilized, every single lymph gland is actually connected to 1 cable television. Just about every computer or maybe forum will be connected to the individual coach cable television. A signal in the supply travels both in guidelines to everyone machines connected about the shuttle cable tv until finally it confirms this supposed receiver."
