Question

after receiving the syn-ack, what is the value of the acknowledgement number sent in the ack, given the syn-ack's sequence number is a hexadecimal 73ff?

Answer 1

After receiving a SYN-ACK with a sequence number of 0x73FF, the acknowledgement number sent in the ACK packet would be 0x7400, which is one more than the received sequence number.

Step-by-step explanation:

• The question involves understanding the Transmission Control Protocol (TCP), which is a core protocol of the Internet Protocol Suite.
• In the TCP three-way handshake process, the step after receiving a SYN-ACK (synchronize-acknowledge) packet is to send an ACK (acknowledge) packet back to the sender.
• The ACK's sequence number will be the SYN-ACK's sequence number plus one.
• If the sequence number of SYN-ACK is given in hexadecimal as 73FF, the acknowledgement number to be sent back in the ACK would be 73FF + 1, which is 7400 in hexadecimal.
