Network Topologies

Question 1

What is a bus topology?

Answer 1

A bus topology is a network in a linear pattern with all computers connected to a single cable acting as the super highway

Question 2

What are the advantages of a bus topology?

Answer 2

The advantages are:
1.It is easy to set up, handle, and implement.
2.It is best-suited for small networks.
3.It costs very little.

Question 3

Disadvantages of Bus Topology

Answer 3

1.It is heavily dependent on the central bus. A fault in the bus leads to network failure.
2.It is not easy to isolate faults in the network nodes.

Question 4

What is a ring topology?

Answer 4

It’s a series of wires forming a ring with computers linking parts of the wire with each other.

Question 5

Advantages of ring topology

Answer 5

1. Is fairly cheap
2. The configuration makes it easy to identify faults in network nodes.
3. The adding or removing of network nodes is easy, as the process requires changing only two connections.

Question 6

Disadvantages of ring topology

Answer 6

1. The failure of a single node in the network can cause the entire network to fail.
2. It stops the whole circuit if you need to place in a new computer

Question 7

What is a star topology?

Answer 7

A star topology is a network with a central hub connected to all other computers surrounding it.

Question 8

What is mesh topology?

Answer 8

Its a network where all computers are connected with all other computers in the system

Question 9

What are the advantages of star topology?

Answer 9

1. It is very reliable – if one cable or device fails then all the others will still work
2. It is high-performing as no data collisions can occur
   3.Less expensive
   4.Easy fault detection because the link are often easily identified.
   5.Easy to add or remove devices

Question 10

What are the disadvantages of star topology?

Answer 10

1. If the central hub fails all computers will go down.

Question 11

What are the advantages of mesh topology?

Answer 11

1.Multiple devices can transmit data at the same time, allowing for high amounts of traffic
2.If one device fails, data transmission is not impacted in the rest of the network (High redundancy)
3.Troubleshooting is easier than with alternative topologies

Question 12

What are the disadvantages of mesh topology?

Answer 12

Very expensive due to all the cables required.
