Network Topologies

Network Topologies

1. BUS Topology

   • Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called Linear Bus topology.

2. RING Topology

   • It is called ring topology because it forms a ring as each computer is connected to another computer, with the last one connected to the first. Exactly two neighbours for each device.

3. STAR Topology

   • In this type of topology all the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node.

4. MESH Topology

   • It is a point-to-point connection to other nodes or devices. All the network nodes are connected to each other. Mesh has n(n-2)/2 physical channels to link n devices. There are two techniques to transmit data over the Mesh topology, they are :
     • Routing
     • Flooding

5. TREE Topology

   • It has a root node and all other nodes are connected to it forming a hierarchy. It is also called hierarchical topology. It should at least have three levels to the hierarchy.

6. HYBRID Topology

   • It is two different types of topologies which is a mixture of two or more topologies.

7. snowflake topology

   • is a star network of star networks

8. point to point

   • Is the simplest topology, with a link between two endpoints.
