3. WHAT IS TOPOLOGY ?
A network topology is the
arrangement of network, including
its nodes and connecting lines.

4. continue
A network topology is the
arrangement with which computer
system or network device are
connected to each other.

5. There are two ways of defining network
geometry: the physical topology and the
logical (or signal)
Topology.

6. There are several common physical
topologies.

7. Bus topology
Bus topology is a network type in which every
computer and network device is connected to
single cable.
it is also called backbone.

9. Features of bus topology
• Its transmits data only one direction.
• Every device is connected to a single cable.

10. Advantages of bus topology
it is cost effective .
Used in small networks.
It is easy to understand.

11. Disadvantages of bus topology
Cables fails then whole network fails.
Cables has limited length.

12. Star topology
In these type of topology all the computers are
connected to a single hub through a cable.
This hub is a central node and all
node are connected to the central node.

13. Star topology

14. Features of star topology
Every node has its own dedicated
connection to the hub.

15. Advantages of star topology
Only that node is affected which has
failed , rest of the nodes can work
smoothly.
Easy to modify.

16. Disadvantages of star topology
Cost of installation is high.
If the hub is fails then the whole
connection is stopped.
