Network Topologies Flashcards
1
Q
What is the definition of a topology?
A
The layout of a network
2
Q
Give 3 examples of network topologies:
A
- Star
- Bus
- Ring
3
Q
What are the advantages of a star topology?
A
- If a node fails, the rest of the network is unaffected
- Simple to add more nodes
- Few data collisions
4
Q
What are the disadvantages of a star topology?
A
- Expensive due to all of the cables
- If there is a problem with the switch, the whole network is affected
5
Q
Describe a bus topology:
A
Devices arranged in a line, all connected to a backbone cable. Devices send data in both directions.
6
Q
Describe a ring topology:
A
Nodes arranged in a ring, all communicate with each other
7
Q
What is the difference between mesh and partial mesh topologies?
A
A mesh topology has every device connected to each other, but a partial mesh has some missing links
