Ring latency
Encyclopedia
In a ring network
, such as Token Ring
, ring latency is the time required for a signal
to propagate once around the ring. Ring latency may be measured in seconds or in bits at the data transmission
rate. Ring latency includes signal propagation delay

Data transmission
Data transmission, digital transmission, or digital communications is the physical transfer of data over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibres, wireless communication channels, and storage media...

Cable
A cable is two or more wires running side by side and bonded, twisted or braided together to form a single assembly. In mechanics cables, otherwise known as wire ropes, are used for lifting, hauling and towing or conveying force through tension. In electrical engineering cables are used to carry...
