I am reading these 2 questions and I do not understand the answers??
1) If a switch has 4 ports, how many broadcast domains does it have? answer: 1 2) If a router has 4 ports, how many broadcast domains does it have? answer: 4 My questions: What does broadcast domain mean here?? is it physical port?? what is the relation between the number of ports and the broadcast domain. I do not understand why a switch with 4 ports has 1 broadcast domain?? and why the router with the same number of ports has 4 broadcast doamins?? Thanks a lot.. |
