The process of connecting to a server that involves three packets being exchanged is the definition of:

The definition of the process involving the exchange of three packets when connecting to a server is known as the three-way handshake. This process is fundamental in establishing a TCP connection between a client and a server, ensuring both parties are ready to communicate.

During the three-way handshake, the first packet is a SYN (synchronize) packet sent from the client to the server, indicating the client's intention to establish a connection. The server then responds with a SYN-ACK (synchronize-acknowledge) packet, acknowledging receipt of the first packet and indicating its readiness to establish a connection. Finally, the client sends an ACK (acknowledge) packet back to the server, confirming the establishment of the connection. This sequence ensures that both the client and server are synchronized, and data can be transmitted reliably.

The understanding of the three-way handshake is crucial in digital forensics and cybersecurity, as it illustrates the mechanics of a TCP connection and sets the stage for further network security considerations.
