Question

State each networking topologies and compare their advantages and usage in today's networking environment

Answer 1

Network topology is the connection of the nodes (computers), in which the communications are taking place.

1) Star topology-

Advantages:

• Easy to add new stations
• Easy to monitor and troubleshoot
• It can accommodate different wiring.

Disadvantages:

• Failure of hub cripples attached stations.
• It requires more number of cables.

2) Ring Topology:

Advantages:

• All the nodes have the equal access.
• Growth in the system has the minimum effect on performance.
• Data travels in one direction.

Disadvantages:

• It is the most expensive topology
• The failure of one computer may affect others.

3) Bus topology:

Advantages:

• Easy to install
• Cheap to install
• Less number of cable required

Disadvantages:

• If cables fails then whole network fails.
• The cable has limited length.
• It is slower than the ring topology.

4) Tree topology:

Advantages:

• point to point for the individual computers
• It is supported by several hardware and software

Disadvantages:

• Overall length of each segment is limited by the type cabling used.
• If more backbone brakes then each system breaks from the network

5) Mesh topology:

Advantages:

• It is the most reliable network topology.

Disadvantages:

• Expensive as cable cost is high.
