What role does the session layer play in the OSI model, and how does it facilitate communication between applications?

The session layer, the fifth layer in the OSI model, provides services to establish, manage, and terminate sessions between applications. It handles session establishment, synchronization, and dialog control, ensuring that data exchange between applications occurs reliably and in the correct order. This layer helps coordinate communication by establishing, maintaining, and terminating connections between hosts, allowing applications to communicate seamlessly.
