Traffic - the amount of users using a network at once trying to access data
Bandwidth - Amount of data distributed in a certain time - 7Topology s we need to know pt.1•Breaks are found easily

•Instillation and configuration complicated - 8Topology s we need to know pt.2•Very fast
•If the hub or switch fails, the nodes go down
- 9topology s•Very Simple
•Only supports a certain number of nodes
•The whole network breaks if there is a break
- 10topologys•Data flows in one direction so if there is a break with one of the nodes some of the data cannot moved.
