A computer network is a collection of two or more computers which are connected together to share information and recourse's.

1. Welcome to Our Presentation
Network Topology

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

3. Types of Topology
1. Bus Topology
2. Star Topology
3. Ring Topology
4. Mesh Topology
5. Tree Topology
6. Hybrid Topology

4. A Bus topology consists of a single cable-called a bus
Connecting all nodes (Computer) On a network without
intervening connectivity device.
Bus Topology

5. Advantages
Works well for small network
Easy to install and configure
Inexpensive
Disadvantages
 Performance decreases
 Weak signals
Cables fails then whole network fails
Advantages and Disadvantages of
Bus Topology

6. A star network is designed with is node (File server, workstation,
peripheral) Connected directly to a central network hub or server.
Star Topology

7. Advantages
Good option for modern networks
Low startup costs
Multiple cable types supported by hub.
Disadvantages
 Cost of installation is high.
 If hub fails then entire network will fail
Require more cables
Advantages and Disadvantages of
Star Topology

8. A Ring topology is one where all workstations
and other devices are connected in a
continuous loop. There no central server.
Ring Topology

9. Advantages
It is cheap to install expand
Equal Access to the recourses
It performs well under a heavy load
Disadvantages
 Failure of one computer can effect the whole
network
 Difficult to troubleshoot the ring
Total dependence in on one cable
Advantages and Disadvantages of
Ring Topology

10. 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 also ring topologies.
Hybrid Topology

11. Advantages
Reliable as error detecting and trouble shooting
is easy
Effective
Flexible
Disadvantages
 Complex in design
 Costly
More hardware requirements
Advantages and Disadvantages of
Hybrid Topology
