A

It is now called a Packet

18
Q

What does the Data Link Layer do to the packet once it hits the NIC?

A

It encapsulates the data with its own header and trailer

19
Q

Once the header and trailer are added on the Data Link Layer what is the new name of the packet?

A

It is now called a Frame

20
Q

What does the Layer 2 Frame include?
