Final answer:
The OSI model's Session Layer is responsible for establishing, managing, and terminating connections to fulfill user requests. It is the fifth layer in the OSI model and is key in managing sessions and communication control between computers.
Step-by-step explanation:
The layer of the OSI model that provides control functions to establish, manage, and terminate connections (as required to satisfy the user request) is the Session Layer.
The Session Layer is the fifth layer in the OSI model and is responsible for managing and controlling the connections between computers. It establishes, maintains, and ends the connections (sessions) between the local and remote applications. This layer provides the protocols and services for organizing and synchronizing communication, including the control over the dialog between the two end systems, and it manages their data exchange. For instance, when you log into a web service, the session layer helps to keep the service from logging you out with each new web page you request.
Other layers such as the Application Layer, Presentation Layer, and Transport Layer serve different purposes. The Application Layer facilitates the user interface and user applications. The Presentation Layer ensures that data is in a usable format and is where data encryption occurs. The Transport Layer is responsible for reliable data transport, error correction, and flow contact
