The room was silent for a moment, the audience mentally traversing the layers she had described. Then, the applause began—not just for her presentation skills, but for the profound elegance of the protocol suite she had so vividly brought to life.

While OSI has 7 layers, Forouzan’s TCP/IP is simplified into 5 layers (Physical, Data Link, Network, Transport, Application). This is the standard for his PPT decks. tcp ip protocol suite behrouz a forouzan ppt top

"On the left, TCP," Elena explained. "Think of this as a registered mail service with a signature required. It uses the 'Three-Way Handshake'—SYN, SYN-ACK, ACK. It establishes a connection.
