Detailed explanation-1: -After receiving SYN packet, server sends the syn ack packet to the client. Not to mention that this is a single tcp packet with syn and ack bit set to 1. The syn sequence number is the initial sequence number of server accepting the connection. The ack part have client sequence number plus one.
Detailed explanation-2: -ACK-The acknowledgment flag is used to acknowledge the successful receipt of a packet. As we can see from the diagram above, the receiver sends an ACK as well as a SYN in the second step of the three-way handshake process to tell the sender that it received its initial packet.
Detailed explanation-3: -TCP connections can detect out of order packets by using the sequence and acknowledgement numbers.
