Short Bytes: Do you know about Ring topology or a Ring network? Here, I’ll tell you the types of a Ring network, Token passing system in a ring network and what are the advantages and disadvantages of a ring topology over other network topology.
What is a Ring Topology?R
Network topology is the interconnected pattern of network elements. A network topology may be physical, mapping hardware configuration, or logical, mapping the path that the data must take in order to travel around the network. There are many identified topologies but they are not strict, which means that any of them can be combined.
ing topology, also known as Ring network, is a type of network topology where each node is exactly connected to two other nodes, forward and backward, thus forming a single continuous path for signal transmission.
There are two types of the Ring Topology based on the data flow:
The Three Stooges are back, and going strong as ever! Twentieth Century Fox Studios and C3 Entertainment released the all new Three Stooges Movie as one of the biggest hit comedies of 2012. Larry, Moe and Curly made a triumphant return to the big screen with The Three Stooges madcap slapstick action from the greatest comedy trio of all time. Mar 22, 2009 THE THREE STOOGES: Sing a Song of Six Pants (1947) (Remastered) (HD 1080p) - Duration: 17:17. 8thManDVD.com™ Cartoon Channel 2,927,120 views. Free three stooges movies.
A Unidirectional ring topology handles data traffic in either clockwise or anticlockwise direction. This data network, thus, can also be called as a half-duplex network. A Unidirectional ring topology is thus easy to maintain compared to the bidirectional ring topology.
Ex: SONET network, SDH network etc.
A SONET/ SDH is a standardized network protocol that transfers data streams over optical fibers. Whereas, a bidirectional ring topology handles data traffic in both the direction and can be a full-duplex network.
Token Passing:What Is Mesh Topology Pdf
Token passing in a Ring Topology is often a term which is talked about. So, a token contains a piece of information which is sent along with data by the source computer. In easier terms, a token is like a permission packet which allows a particular node the permission to release information over the network.
A token is regularly passed from one node to another. And if a node has some information to pass on the network, the node releases the information. If the node does not have any data to release on the network, then it transfers the token to the next node.
The nodes with token are the ones only allowed to send data. Other nodes have to wait for an empty token to reach them.
Advantages of Ring topology:
Disadvantages of Ring topology:
Ex: Let’s say A, B, C, D, and E are a part of the ring network. The data flow is from A towards B and henceforth. In this condition, if E wants to send a packet to D, the packet must traverse the entire network to reach D.

Alternatively referred to as a line topology, a bus topology is a network setup in which each computer and network device are connected to a single cable or backbone. Depending on the type of network card used in each computer of the bus topology, a coaxial cable or an RJ-45 network cable is used to connect them together.
The following sections contain both the advantages and disadvantages of using a bus topology with your devices.
