>Number of the linkages in the mesh topologies is given by=

N(N-1) =no of nodes(no of nodes -1) 2 2

>It is categorized as point to point.

> It is categorized as multipoint.> It consist of the back bone to which all the

nodes are connected> Its main advantage is that , any message can

be conveyed to all usingsingle link.> If there is a failure in any of the link then it

doesnot concer with other nodes

• >Star topology is arrangement of all nodes connected to a single controlling device

• Known as hub.• > as many nodes can connected in this

topology depending upon the number of• Available port• >if a single node is blown there is no effect

of it on other

• >Ring topology is arrangement of all nodes connected to each other in circular manner, as shown in figure.

• >its size depends on number of nodes.• >if a single node is blown whole

arrangement is disturbed.

• >Tree topology is arrangement of all nodes ,as a mixture of bus topology as well as star topology, as shown in figure.

• >It is in a hierarchical structure so as it is called as tree topology.

• >if a single node is blown ,there is no effect on other.

• >Hybrid topology is arrangement of all topologies connected or linked to each other, as shown in figure.

• >It is in a hierarchical structure so it can be categorized easily.

• >Large amount of the work can be divided and different departments can linked depending upon ther topological requirement.
