Network Topologies

Question 1

What is a Star Topology?

Answer 1

A network set out in the shape of a star, branching from one central hub to the outliers

Question 2

Advantages of a Star Topology

Answer 2

• Easy to install and wire.
• No disruptions to the network when connecting or removing devices.
• Easy to detect faults and to remove parts

Question 3

Disadvantages of a Star Topology

Answer 3

• Requires more cables

- If the hub fails then the nodes attached are disabled.

Question 4

What is a Bus Topology?

Answer 4

A main run of cable with a terminator at each end. All nodes are connected to the cable.

Question 5

Advantages of a Linear Bus Topology

Answer 5

• Easy to connect a computer

- Requires less cable

Question 6

Disadvantages of a Linear Bus Topology

Answer 6

• Network shuts down if there is a break in the main cable.
• Terminators are required at both ends
• Difficult to identify the problem

Question 7

What is a Ring topology?

Answer 7

A localised network joined by a central line that forms a loop

Question 8

Advantages of a ring Topology?

Answer 8

• Information can flow both ways around the ring

- Easy to set up

Question 9

Disadvantages of a ring Topology?

Answer 9

• Loop needs to be completed at one end

- A break in the cable brings the server down.

Question 10

What is a Mesh Topology?

Answer 10

All computers are connected with eachother which requires a vast amount of cables
