Topologies

Question 1

What is a ring network?

Answer 1

Components connected in a loop so the data goes through all of them.

Question 2

What is a bus network?

Answer 2

Central cable with components attached so the data is sent to all but only the intended one receives it.

Question 3

What is star network?

Answer 3

Connected through one central hub.

Question 4

Name 2 advantages of ring?

Answer 4

All the data travels (very quickly) in one direction; performance is better than in a bus topology; additional computers or other clients don’t affect the performance and there is no need for a server.

Question 5

Name 2 advantages of bus?

Answer 5

Adding and taking away computers is easy with a bus network; setting one up is a lot more simple and it normally costs less than a ring or star network.

Question 6

Name 2 advantages of star?

Answer 6

Better performance than a Bus network because the signal does not pass through every device; adding new items or taking ones away doesn’t affect the rest of the network; the central hub means it can be easier to monitor the network and it is easier to detect problems from individual clients.

Question 7

Name 2 disadvantages of ring?

Answer 7

The data must pass through every computer before reaching the one it needs so a ring topology is slower than a start one; it can often be more expensive and when one computer is broken the ring will be disconnected and the other computers will no longer be able to share data.

Question 8

Name 2 disadvantages of bus?

Answer 8

There is a limit to how many devices can be added to the Bus cable; the speed of the network will decrease as more devices are added to it; security is lower and if the central cable breaks down, the whole network will be destroyed.

Question 9

Name 2 disadvantages of star?

Answer 9

If the central device goes down so does the whole network, the performance/ speed of the network depends on the hub and the number of computers (etc.) that can be added depends on the main device.
