Topologies

Question 1

Bus Topology

Answer 1

One common linking cable​

Nodes connected off the cable​

Cheap

Question 2

disadvantages of bus topology

Answer 2

Slows down when heavy traffic

​Lots of data collisions​

Breakage to cable affects the whole network​

Limited distance possible

Question 3

Ring Topology

Answer 3

One common linking cable​

Passes all nodes​

One direction traffic​

Fast performance

Question 4

disadvantages of ring topology

Answer 4

But if the cable gets damaged the ​

whole network goes down.

Question 5

Star Topology

Answer 5

Shared link to server(s)​

Most common​

Few data collisions​

Fast

Question 6

Mesh Topology

Answer 6

Each component is linked to every other component.​

If one node goes down, the network will continue to work.​

Can handle a lot of data, as there are multiple paths to each node

Question 7

what must happen to data when it is sent across the network?

Answer 7

must be split into small, equal size chunks.​

Question 8

Each chunk of data includes some important information:

Answer 8

The destination address​

The source address​

The packet number (To help the file to be reassembled at the destination)​

Error checking (To make sure the data arrived safely.)​

Question 9

packet switching

Answer 9

Once the data is split into packets, the packets will take different routes across the network to avoid heavy traffic and damaged cables.
