Explain the OSI model as you would to a capable student, in 3-4 sentences.

The OSI model is a seven-layer framework that describes how data travels from an application on one computer to an application on another across a network. Each layer handles a specific function—from the physical transmission of electrical signals at the bottom (Layer 1) to the actual application software at the top (Layer 7)—with each layer providing services to the layer above it. Think of it like sending a package: the top layers prepare your message, middle layers add addressing and route it through the network, and bottom layers handle the actual physical delivery. Understanding this model helps you troubleshoot network problems by isolating which layer is failing.
