The TCP handshake process involves three steps: SYN, SYN-ACK, and ACK.
SYN (Synchronize): The client initiates the TCP connection by sending an SYN packet to the server, indicating its intention to establish a connection.
SYN-ACK (Synchronize-Acknowledge): Upon receiving the SYN packet, the server responds with an SYN-ACK packet, acknowledging the client's request and providing its initial sequence number.
ACK (Acknowledge): The client acknowledges the server's SYN-ACK packet by sending an ACK packet. This packet also contains the next sequence number the client expects to receive.
After the three-way handshake is completed, the TCP connection is established, and data transmission can begin.
