In the OSI model, which layer directly follows the Application layer when moving down the stack?

Explanation:
In the OSI model, the layer right beneath the Application layer is the Presentation layer, which handles data formatting, encoding, and security features like encryption and compression. This layer ensures that data produced by applications is represented in a standard form that the receiving end can interpret, regardless of differences in data representation. The Session layer sits below the Presentation layer and manages dialogue and control functions, but it doesn’t handle data formatting, so it isn’t directly below the Application. So, the direct follower of the Application layer is the Presentation layer.
