Handshake: In the context of networking, a handshake is a protocol or process used to establish a connection between two systems. A common example is the TCP three-way handshake, which involves a synchronization (SYN) message sent by the client to the server, an acknowledgment of the synchronization (SYN-ACK) sent by the server back to the client, and a final acknowledgment (ACK) sent by the client to the server. This sequence of messages confirms that both parties are ready to communicate and establishes a reliable connection.
