Q
Delimiting and synchronization of data exchange is provided by __________
AA. Application layer
BB. Session layer
CC. Transport layer
DD. Link layer
Correct Answer:
B. B. Session layer
Explanation:
The session layer provides the mechanism for opening, closing and managing a session between end-user application processes. The session layer 5 is responsible for establishing managing synchronizing and terminating sessions. In TCP/IP protocol stack, the functions of the session layer are handled by the transport layer itself and thus the session layer is missing from the TCP/IP model.
