What are the Layers of the OSI Model?

The OSI model is a system-level networking model that describes the topology of a network. The model consists of seven layers: Physical, Data Link, Transport, Network, Application, and Management. Each layer is responsible for providing a specific function. For example, the Physical layer provides connectivity between devices and the Data Link layer is responsible for data transmission. The Transport layer is responsible for routing data and the Network layer is responsible for managing the network. The Application layer is responsible for providing services to the devices on the network and the Management layer is responsible for managing the network. Each layer in the OSI model has a specific purpose and each layer in the OSI model has a specific role to play in the overall system.
