Hub

2.

Switch

3.

Router

4.

Question 8

Describe 5 network topologies (briefly) and give an advantage and a disadvantage for each. Rank the technologies in order of least resilient to most resilient to faults.

Question 9

In what cases would you use an amplifier instead of a repeater? What is it about the behavior of each that makes one better than the other, and what specifically would be an issue for a WAN deployment cross country?
