2. 2 or more devices connected together via
wire or wire-less mode for the purpose of
communication.
The device could be a computer or laptop or
mobile or printer….etc.
3. Physical and logical arrangement of devices in
a network is known as Topology.
Topology types
◦ Mesh Topology
◦ Star Topology
◦ Bus Topology
◦ Ring Topology
4. Each device ha a dedicated point-point link to
every other devices on the network.
In Mesh topology if a network has n devices
then n(n-1)/2 links are there.
For example If there are 5 devices in a mesh
topology, then 5(5-1)/2=10 links are there.
5.
6. Each device in a network is connected with a
central device known as hub.
If a node wants to send date to other note
then should be through the hub.
7.
8. All devices in a network is connected in a
central back bone cable is known as Bus link
or Bus line.
It is a multi point network.
9.
10. In Ring topology each device is connected
with its immediate neighbor device.
