Question 1

What does the Data Link layer do with a frame after it receives it?

Accepted Answer

first, it checks the destination MAC address to make sure that it is intended for itself. then it calculates the CRC and compares it to the incoming frame's CRC to make sure that the values are the same. Next, it strips off the header and trailer information. then the resulting packet is sent up to the Network layer.

Question 2

What is encoding, and where does it take place?

Accepted Answer

Encoding is a process performed by the Physical layer that takes the frame from the Data Link layer and changes it into 1s and 0s to be transmitted onto the medium. the type of signal that it is changed into is dependent on the type of media.

Question 3

One job that a router performs is that of gatekeeper, which means that it can be configured to only allow certain packets access into the network based on a list of rules. What is that process called?

Accepted Answer

A)  media control 
B)  packet forwarding 
C)  access control 
D)  signal bounce 
A)  media control
