The Session layer (Layer 5)
Explanation:
The OSI (Open Systems Interconnection) seven-layer model is a reference model that explains how devices (or applications) communicate over the network. The model consists basically of seven different layers which are;
i. Layer 1 or the physical layer
ii. Layer 2 or the data-link layer
iii. Layer 3 or the network layer
iv. Layer 4 or the transport layer
v. Layer 5 or the Session layer
vi. Layer 6 or the presentation layer
vii. Layer 7 or the application layer.
Out of the seven layers, the session layer (layer 5) keeps track of a system's connections to send the right response to the right computer by setting up, coordinating and managing these connections. It controls, establishes and maintains the connection between multiple computers or applications on a computer.
