a ring can operate as a communicationnetwork if it perform the following three functions. 1.data insertion 2.data reception 3.data removal
1.these functions are mainly provided by the repeaters.
2.each repeater also act as the device attachment point. hence the function of data insertion is accomplished by the repeaters.
3.data is transmitted in the form of packets.
4.each packets consists of a destination addrtess field.as this packet by a repeater , the destination address field is
Ring topology doesn't fare well if one of the "nodes" in the ring dies... because each node has to actively send any data that it has and then pass the token to the next node. This problem (of the whole network dying if one of its nodes dies) can be overcome using a double ring and some "wire-around-the-world" heroics, but this is cited as the classic and main disadvantage of that topology.
mother India..... (**********) i am still luking 4 the answer
The main advantage of ring topology is that data flows in a singular direction, eliminating collisions. However, if one node in the ring breaks down, the entire network ceases to function.

Advantage: No packet collisions Disadvantage: Single point of failure
Ring topology is the passive topology in computer networks
Topology: physical ring of trees, logical ring
This question is phrased badly, as all networks have a particular type of topology. Briefly, these resolve to 'cloud' (many to many), 'star' (many to a central point) and ring (each node connects to two others, which results in a complete ring). See topic 'Network topology'. The issues to be dealt with are latency, connectivity and fault tolerance.
