What are the seven OSI model layers in order from Layer 1 to Layer 7?
- APhysical, Data Link, Network, Transport, Session, Presentation, Application
- BPhysical, Data Link, Transport, Network, Session, Presentation, Application
- CPhysical, Network, Data Link, Transport, Session, Presentation, Application
- DPhysical, Data Link, Network, Transport, Presentation, Session, Application
Why this is the answer
Bottom to top the order is Physical, Data Link, Network, Transport, Session, Presentation, Application (mnemonic: Please Do Not Throw Sausage Pizza Away). The distractors each swap an adjacent pair: Network/Transport (L3/L4), Data Link/Network (L2/L3), and Session/Presentation (L5/L6) — a common ordering mistake.
