How many layers does the OSI model have?

Explanation:
Seven layers form the OSI model, a standard framework for network communication. They are, from bottom to top: Physical, Data Link, Network, Transport, Session, Presentation, Application. Each layer handles a distinct set of tasks, from sending raw bit streams over physical media to providing end-user network services. The option with eight layers isn’t part of the official OSI model, so seven is the correct count.
