This document discusses different network topologies. It defines a network topology as how computers are arranged and connected in a network. There are several types of topologies including bus, star, ring, tree, mesh, and hybrid. Each has their own advantages and disadvantages related to things like cost, scalability, reliability, and ease of management. The document provides details on each topology type through examples and explanations of their characteristics.

2. What is Network Topology?
A computer network is a collection of
two or more computers which are
connected together to share
information and resources.

5. Bus Topology
A Bus topology consists of a single cable—called a
bus— connecting all nodes on a network without
intervening connectivity devices
- Shubham Agrawal

6. Advantages of Bus Topology
• Works well for small networks.
• Relatively inexpensive to implement.
• Easy to expand joining two cables together.
• Used in small network.

7. Disadvantages of
Bus Topology
• Management costs can be high
• Cables fails then whole network fails.
• Cables has a limited length.
- Shubham Agrawal

8. Star Topology
A star network is designed with each node
(file server, workstation, peripheral)
connected directly to a central network hub
or server.
- Shubham Agrawal

9. Advantages of Star Topology
• Good option for modern
networks
• Low startup costs
• Easy to manage
• Offers opportunities for
expansion
• Most popular topology in
use wide variety of
equipment available
- Shubham Agrawal

10. Disadvantages of
Star Topology
• Hub is a single point of failure
• Requires more cable than the bus
• Cost of installation is high.

11. Ring topology
A ring network is one where all workstations
and other devices are connected in a
continuous loop. There is no central server.
- Shubham Agrawal

12. Advantages of Ring Topology
• Easier to manage; easier to
locate a defective node or
cable problem
• Well-suited for
transmitting signals over
long distances on a LAN
• Handles high-volume
network traffic
- Shubham Agrawal

13. Disadvantages of
Ring Topology
• Expensive
• Requires more cable and
network equipment at the
start
• Not used as widely as bus
topology
– Fewer equipment options
– Fewer options for expansion
to high-speed communication
- Shubham Agrawal

14. Tree topology
• It has a root node and
all other nodes are
connected to it forming
a hierarchy. It is also
called Hierarchical
Topology.
- Shubham Agrawal

15. Advantages Of Tree Topology
• Extension of Bus and Star Topology.
• Expansion of nodes is possible and easy.
• Easily managed and maintained.
- Shubham Agrawal

16. Disadvantages Of Tree Topology
• Heavily cabled.
• Costly.
• If more nodes are added maintenance is
difficult.
• Central hub fails, network fails.
- Shubham Agrawal

17. Mesh Topology
It is a point-to-point connection to other
nodes or devices. Traffic is carried only
between two devices or nodes to which it is
connected. Mesh has n(n-2)/2 physical
channels to link hn devices.
- Shubham Agrawal

18. Advantages Of Mesh Topology
• Each connection can carry its own data load.
• Fault is diagnosed easily.
• Provide security and privacy.
- Shubham Agrawal

19. Disadvantage of mesh topology
• Installation and configuration is difficult.
• Cabling cost is more.
• Bulk wiring is required.
- Shubham Agrawal

20. Hybrid Topology
It is the mixture of two or more topologies.
Therefore it is called Hybrid topology. A
hybrid topology combines characteristics of
linear bus and star and/or ring topologies.

- Shubham Agrawal

21. Advantages of hybrid topology
• Reliable as error detecting and trouble
shooting is easy.
• Effective.
• Scalable as size can be increased easily.
• Flexible.

22. Disadvantages Of Hybrid
Topology
• Complex in design.
• Costly.
