Nov 1, 2022 · The OSI Model is a framework for understanding network communications. It breaks the network stack down into seven layers. The layers range from the low-level physical layer up to the application layer residing closest to a computer user. At the heart of the model are the mid-level network and transport layers. Foundation Models Defined.
