2. What is Topology ?
Types of topology?
Advantages and disadvantage
of topology

3. • The physical arrangement of the
devices in the network .
• It represent that how a device connect
to other device and what is the
behavior of data transmission among
the devices.

4. Physical
Topology
Logical

5. 5
• Single node topology
• Bus topology
• Ring topology
• Star topology
• Mesh topology
• Tree topology
• Hybrid topology

6. In a single node topology only two system can
communicate via single node .
Node :- Connected link between the
devices create node.

7. Benefits
• High speed
• Easy to create
• Security, no third party
can access.
• Easy to troubleshoot.
• Only to system can
communicate .
• Fixed network .
Drawbacks

8. Bus Topology
• There is a single cable (RJ 8 ,10Mbps) work
as a backbone cable and all systems
connected through its back bone.
• Terminator :- It blocks the flowing signals.
• Value of terminator is 50 ohms.

9. Benefits
• More than two
system can
communicate.
Drawbacks
• Single point of failure.
• If backbone fails entire
network will fail
• Low bandwidth because
of broadcasting.

10. • In this topology every pc connects to next pc in
a form of ring, so we required two NIC per
system, and data travels in form of token so it is
also known as token ring topology.
• Logical ring topology :- In a logical ring topology
MAU device is used .

12. • NO broadcast
• No use of co-axial
cable.
• Secure than bus
topology.
• Required two NIC
in system.
• Low performance.
• Very difficult to
create and
troubleshoot
• If one point fails
entire topology
fails.

13. • The world most popular
network communication
topology available .
• There is a central
network device (Switch,
HUB) by which every
device can communicate
to other device directly.

15. • Each Pcs are directly connected to each other .
• Easy to create and troubleshoot .
• Create a central point of management .
• High bandwidth because individual
transmission.

16. • In mesh topology every device is
individual connected to other PC.
• No central management available
in mesh topology.
• Mainly it is used for connect the
routers in the wide area network.

18. TREE TOPOLOGY
I t is a
combination
of bus and
star topology.

19. It is a combination of two or
topologies .
1st combination – star + bus topology
2nd combination – ring +star topology
