Star topology
Bus topology

5. • Star topology is a network topology in which each network
component is physically connected to a central node such as a
router, hub or switch. In a star topology, the central hub acts
like a server and the connecting nodes act like clients

6. • 1.Less expensive
• 2.Easy to install and
reconfiguration.
• 3.Robustness
• Failure of central hub will
effect the entire network.
• Performance is based on the
single concentrator i.e. hub.

7. • In a tree topology, there is one central node (the “trunk”),
and each node is connected to the central node through a
single path. Nodes can be thought of as branches coming
off of the trunk.

8. .We can add new devices to the existing
network.
.Error detection and error correction are very
easy in a tree topology
• If the central hub gets fails the entire
system fails.
• The cost is high because of the cabling.
• If new devices are added, it becomes
difficult to reconfigure

9. • A ring network is a network topology in which each node
connects to exactly two other nodes, forming a single
continuous pathway for signals through each node a ring.

10. • The data transmission is high-speed.
• The possibility of collision is minimum in this
type of topology.
• Cheap to install and expand.
• It is less costly than a star topology.
• Troubleshooting is difficult in this topology.
• Less secure.

11. • The mesh topology is a type of topology in which every
device or computer is connected to every other device. Each
device not only sends its signals but also receives signals
from other devices.

12. • Mesh topology is robust.
• Provides privacy & security.
• Fault identification and isolation is easy.
• Huge amount of cabling and I/O ports
required.
• Installation and reconnection is difficult.
