2. I m heartly thank full to our respected sir
for giving me such a great opportunity to
Give the presentation.
I m also thanks full to our respected Beni Thomes
sir for helping me in making this presentation.

3. Network Topology is physical arrangement of
connecting various computer for networking.

4.  Ring topology
 Bus topology
 Star topology
 Tree topology

5. Here all the nodes are joined together to
form a ring. There is no central server in this
case.

6. ADVANTAGES:
 Short cable length
 Suitable for optical fibres
DISADVANTAGES:
 Network reconfiguration is difficult
 Topology affects the access protocol

7. Here all the nodes share a common bus of
connecting cables.

8. ADVANTAGES:
 Short cable length and simple wiring layout
 Easy to extend
DISADVANTAGES:
 Fault identification is difficult
 Fault isolation is difficult

9. Here all the nodes are connected to a
centralized computer.

10. ADVANTAGES:
 Fault identification is easy
 Fault isolation is easy
DISADVANTAGES:
 Long cable length
 Difficult to expand

11. Here nodes are linked in a stage or phase.

12. ADVANTAGES:
 Easy to expand
 Fault isolation is easy
DISADVANTAGES:
 Dependent on the root
 Difficult for installation
