This is a TCP/IP 3-Way Handshake and Data Exchange Diagram Template. It illustrates the Transmission Control Protocol (TCP) communication process between client and server, showing the 3-way handshake (SYN, SYN-ACK, ACK), data segment exchange, and connection termination (FIN, ACK) with sequence and acknowledgment numbers. Ideal for network engineers, IT students, or protocol analysts, this template helps visualize TCP’s connection-oriented data transmission, session establishment, and teardown to support network protocol learning and troubleshooting.
