TCP/IP three-way handshake is a technique used to establish a communication session between two devices on a network. It consists of three steps:
1. SYN (synchronization): The sender sends a SYN packet to the receiver which contains the initial sequence number (ISN) and other information that both parties need to start communicating.
2. SYN-ACK (acknowledgement): The receiver sends back an acknowledgement (ACK) packet, containing its own ISN and the ISN from the sender.
3. ACK (acknowledgement): The sender sends back an ACK packet with its own ISN and the ISN from the receiver. This establishes a communication session between the two devices.
