Answer 1

Answer:

the number of data bytes in the packet will be 980..

Answer 2

Answer:

Data bytes in the packet = 980

Explanation:

HLEN is 5.

The length of header is 20 bytes. 5 x 4 = 20 bytes

value of the TOTAL LENGTH field is 1000.

Data bytes in the packet = TOTAL LENGTH - HEADER

Data bytes in the packet = 1000 - 20 = 980
