Advantages of Ring Topology 1) This type of network topology is very organized. Each node gets to send the data when it receives an empty token. This helps to reduces chances of collision. Also in ring topology all the traffic flows in only one direction at very high speed. 2) Even when the load on the network increases, its performance is better than that of Bus topology. 3) There is no need for network server to control the connectivity between workstations. 4) Additional components do not affect the performance of network. 5) Each computer has equal access to resources. Disadvantages of Ring Topology 1) Each packet of data must pass through all the computers between source and destination. This makes it slower than Star topology. 2) If one workstation or port goes down, the entire network gets affected. 3) Network is highly dependent on the wire which connects different components

Dear friend, **Meaning** A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travel from node to node, with each node along the way handling every packet. Rings can be unidirectional, with all traffic travelling either clockwise or anticlockwise around the ring, or bidirectional (as in SONET/SDH). Because a unidirectional ring topology provides only one pathway between any two nodes, unidirectional ring networks may be disrupted by the failure of a single link. **Advantages** -Data is quickly transferred without a ‘bottle neck’. (very fast, all data traffic is in the same direction) -The transmission of data is relatively simple as packets travel in one direction only. -Adding additional nodes has very little impact on bandwidth -It prevents network collisions because of the media access method or architecture required. -This type of network topology is very organized. Each node gets to send the data when it receives an empty token. This helps to reduces chances of collision. Also in ring topology all the traffic flows in only one direction at very high speed. -Even when the load on the network increases, its performance is better than that of Bus topology. -There is no need for network server to control the connectivity between workstations. **Disadvantages** -Data packets must pass through every computer between the sender and recipient therefore this makes it slower. -If any of the nodes fail then the ring is broken and data cannot be transmitted successfully. -It is difficult to troubleshoot the ring. -Because all stations are wired together, to add a station you must shut down the network temporarily. -In order for all computers to communicate with each other, all computers must be turned on. -Total dependence upon the one cable.

What are the Advantages & Disadvantages of Ring Topology Advantages • Very orderly network where every device has access to the token and the opportunity to transmit • Performs better than a bus topology under heavy network load • Does not require a central node to manage the connectivity between the computers • Due to the point to point line configuration of devices with a device on either side (each device is connected to its immediate neighbor), it is quite easy to install and reconfigure since adding or removing a device requires moving just two connections. • Point to point line configuration makes it easy to identify and isolate faults. • Reconfiguration for line faults of bidirectional rings can be very fast, as switching happens at a high level, and thus the traffic does not require individual rerouting Disadvantages • One malfunctioning workstation can create problems for the entire network. This can be solved by using a dual ring or a switch that closes off the break. • Moving, adding and changing the devices can affect the network • Communication delay is directly proportional to number of nodes in the network • Bandwidth is shared on all links between devices • More difficult to configure than a Star: node adjunction = Ring shutdown and reconfiguration

Ring Topology: Advantages are Adding additional nodes is easy. All computers have equal access on network. Disadvantages are Difficult to configure If Cable breaks, then whole Network will goes down. If any link goes down, then network will also goes down. Only one medium for Data Transmission so Transmission Speed is very slow.
