Layer 6: Presentation Layer – Data formatting, encryption, and compression. Layer 5: Session Layer – Managing sessions between applications. Layer 4: Transport Layer – End-to-end connections, flow control, and segmentation (e.g., TCP, UDP). Layer 3: Network Layer – Logical addressing and routing (e.g., IP). Layer 2: Data Link Layer – Physical addressing (MAC addresses) and error detection. Layer 1: Physical Layer – Raw data transmission over physical media (cables, radio waves) Last updated 15-feb-2026
