In the OSI model, which layer follows the Presentation layer?

The layer that follows the Presentation layer in the OSI (Open Systems Interconnection) model is the Session layer. The OSI model consists of seven layers, each serving a specific function in the data communication process. The Presentation layer is responsible for translating and formatting data so that it can be understood by the application layer; it handles data representation and encryption.

The Session layer, which comes next, is responsible for establishing, managing, and terminating sessions between applications. It enables applications to connect and communicate over the network by managing the dialog (the exchange of information) between the two entities. This includes handling the opening, closing, and managing of sessions, which are crucial for effective communication over a network.

Understanding the functions of these layers helps in grasping how network communication is structured and what roles each layer plays in ensuring that data is transmitted correctly and efficiently.
