Need help on these question please!!!

8. How many bytes of overhead are there in an Ethernet frame? Include the header and trailer,

but do not include the preamble in the frame. You will need to look up the length of the

header and trailer.

8a. An Ethernet frame contains 500 bytes of payload data, which is an encapsulated IP packet

from layer 3. Calculate the percentage of the frame that is overhead (do not include the

preamble in the frame). (You will need to use the number of overhead bytes calculated in

the problem above.)
