Which layer of the OSI model manages connections between local and remote applications?

The layer of the OSI model that manages connections between local and remote applications is the Session layer, which is the fifth layer. This layer is responsible for establishing, maintaining, and terminating sessions between applications. It provides services such as dialog control, which determines whether the communication is half-duplex or full-duplex, and it ensures that data is properly synchronized between connected applications.

By managing sessions, the Session layer plays a crucial role in enabling the smooth transfer of information and maintains the state of the connection across the communication process. This includes handling session tokens, controlling dialog, and managing the closure of sessions once the communication is complete.

Understanding the role of the Session layer is critical, as it enables users to connect and interact with services reliably, regardless of whether they are on the same local network or connected over the internet.
