Switches

Question 1

What is a collision domain?

Answer 1

Network segments with two or more devices sharing the same bandwidth
Ex: hub
You can create a much better network with switches

Question 2

What are bridges?

Answer 2

Used to break up collision domains (software)

Now router creates logical segmentation while swicthes uses physical

Question 3

What are switches?

Answer 3

Independent bandwidth on each port
Private, dedicated collision domains, low latency, low cost, harware based (ASIC)
No modification to data packet

Question 4

List 2 limitiations to Layer 2 switching

Answer 4

Absolutely need to break up domains properly.

Best when its working within 80% local

Question 5

What are the differences and similarities of bridges and switches

Answer 5

Bridges- soft ware based
Switches- hardware; ASIC chips help male filtering decisions
Switches can be used as a multiport bridge
Both- make forwarding decisions based on layer 2, and send layer 2 broadcasts
Both learn MAC address by examining source address of frame received
