Osi Model Questions Medium
The purpose of the OSI Model's Session layer is to establish, manage, and terminate communication sessions between two or more network devices. It provides services that allow applications running on different hosts to establish and maintain a connection, synchronize their communication, and manage the flow of data between them. The Session layer is responsible for session establishment, maintenance, and termination, as well as handling session checkpoints, recovery, and synchronization. It ensures that data is delivered reliably and in the correct order, and also handles security and authentication mechanisms for the session. Overall, the Session layer plays a crucial role in facilitating and managing the communication between applications across a network.
