3. Network Topology refers to layout of a network. How different
nodes in a network are connected to each other and how they
communicate is determined by the network's topology.

4. Logical topology: how data is transmitted between
nodes
Physical topology: physical layout of nodes on a
network
Physical and logical topology:

5. NETWORK TOPOLOGIESNETWORK TOPOLOGIES
There are three basic There are three basic
configurations used to connect configurations used to connect
computers they are the computers they are the
Bus Bus
Ring Ring
StarStar
Mesh Mesh

6. Bus topologyBus topology
 All networked nodes are interconnected, peer to All networked nodes are interconnected, peer to
peer, using a single, open-ended cable.peer, using a single, open-ended cable.
Both ends of the bus must be terminated.

7. Bus topology

8. BUS TOPOLOGY

9. Ring TopologyRing Topology
In Ring topology each node is connected to the In Ring topology each node is connected to the
two nearest nodes so the entire network forms a two nearest nodes so the entire network forms a
circle. circle.
Data only travels in one direction on a Ring Data only travels in one direction on a Ring
network. network.

10. Each networked workstation had two connections:
one to each of its nearest neighbors.

12. Ring topology

13. Star topologyStar topology
In a Star topology every node is connected In a Star topology every node is connected
through a central device such as a Hub, through a central device such as a Hub,
Switch or Router Switch or Router
HUB

14. Star topology

16. What is a Hub?What is a Hub?
A hub is usually a small rectangular box, A hub is usually a small rectangular box,
often made of plastic, which receives its often made of plastic, which receives its
power from an ordinary wall outlet power from an ordinary wall outlet

17. What is a Switch?What is a Switch?
A A network switchnetwork switch is a small hardware is a small hardware
device that joins multiple computers device that joins multiple computers
together within one local area network together within one local area network
(LAN).(LAN).

18. What is a Router?What is a Router?
RoutersRouters are physical devices that join are physical devices that join
multiple wired or wireless networks together.multiple wired or wireless networks together.

19. A network setup where each computer and
network device is interconnected with one another.
Mesh topology

20. The number of connections in this network can be
calculated using the following formula (n is the
number of computers in the network): n(n-1)/2.
