Network Topologies

Question 1

What is a network topology

Answer 1

the layout of connections in a network

Question 2

Describe a star topology

Answer 2

The star network has a central device directly connected to all the other nodes

Question 3

What are the advantages of a star topology

Answer 3

• Very Reliable
• Very few data collisions
• Good security
• Simple to add computers or remove

Question 4

What are the disadvantages of a star topology

Answer 4

• Expensive
• Extra hardware (Switch or hub)
• If the hub/switch goes down the whole network does

Question 5

Describe a mesh topology

Answer 5

Each node relays the data it receives to other nodes and there are no central hub

Question 6

What are the advantages of a star topology

Answer 6

• Very robust
• There is no central node to fail
• It can handle high data traffic
• Data packets can be sent simultaneously

Question 7

What are the disadvantages of a star topology

Answer 7

• Very expensive

- Lots of cable

Question 8

Describe a bus topology

Answer 8

Bus topology is a network topology in which all of the various devices in the network are connected to a single cable or line

Question 9

What are the advantages of a bus topology

Answer 9

• Its easy to set up
• Cheap
• Good for LAN

Question 10

What are the disadvantages of a bus topology

Answer 10

• Dependant on the central cable
