The sequence of SYN, SYN/ACK, and ACK packets is known as the three-way handshake high five two-way handshake four-way handshake

Which segment is sent by the client to synchronize sequence numbers during the three-way handshaking process?ACK segmentSYN + ACK segmentFIN segmentSYN segment

What is meant by handshaking? Explain with neat diagram

TCP SYN Flood attack uses the three-way handshake mechanism.1. An attacker at system A sends a SYN packet to victim at system B.2. System B sends a SYN/ACK packet to victim A.3. As a normal three-way handshake mechanism system A should send an ACK packet to system B, however, system A does not send an ACK packet to system B. In this case clientB is waiting for an ACK packet from client A.This status of client B is called _________________Select one:a. "full-open"b. "half-closed"c. "half open"d. "xmas-open"

The figure below shows the timing diagram for a TCP connection between Hosts A and B from the beginning to the end. First, we see the 3-way handshake. The client (Host A) combines 50 bytes of data with the last ACK of the 3-way handshake. The server (Host B) combines 100 bytes of data with the ACK packet sent back to the client. The client (Host A) closes the connection at this point which results in a FIN segment being sent to the server (Host B), which is combined with the ACK for the 100-byte data. After a little while, the server (Host B) closes the connection as well.Enter the numeric values for a, b, c, d, e and f in the spaces provided below. No explanation is necessary. 0.5 mark for each.
