A TCP Header from Host A to Host B includes these fields SEQ

A TCP Header from Host A to Host B includes these fields: SEQ=5 ACK=80 Data=\"computer\"

Show the equivalent fields for the acknowledgement from Host B to Host A with no data:

SEG=____ ACK=____

Solution

Host B will resend SEQ=80 and ACK=6.

Reason the reciever machine will send the sequence number of the ack value and in turn it will wait for the next message and so it will increment the sequence value by 1 stating it is ready to recieve next message
