Answer:
Network topology:Network
topology is the arrangement of the various elements of a computer network. Such
as links, nodes, etc.
Deferent type network topology:Computer
network topology can be classified 6 classes. The name are show down_
1. Star
network topology.
2. Ring
network topology.
3. Completely
connected network topology.
4. Bus
network topology.
5. Tree
network topology.
6. Hybrid
network topology.
Star network topology:In
a star configuration of computer network, there is a host computer which is
attached to local computer through multiple communication lines.
Ring Topology: This
configuration is non-host or ring arrangement of communicating equals. A
network topology is set up in a circular fashion in such a way that they make a
closed loop. This way data travels around the ring in one direction and each
device on the ring acts as a repeater to keep the signal strong as it travels.
Completely connected network topology:
A completely connected network has a separate physical link for connecting each
node to any other node. Thus, each computer of such network has direct
dedicated link, called a point to point link with all other computers of the
network.
Bus network topology:
The bus network topology is single transmission medium is shared by all nodes.
When a particular computer wants to send a message to another computer, it
appends the destination address to the message and checks whether the
communication line is free. As soon as the line become free, it broadcasts the
massage on the line.
Tree network 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.
Hybrid network topology:It
is two different types of topologies which is a mixture of two or more
topologies. For example if in an office in one department ring topology is used
and in another star topology is used, connecting these topologies will result
in Hybrid Topology.
