Which layer of the OSI reference model is responsible for end-to-end process-to-process communication, flow control, and error recovery using protocols such as TCP and UDP?
Answer and explanation
Correct answer: A. Transport layer
- Step 1: Trace the 7 OSI layers: Physical, Data Link, Network, Transport, Session, Presentation, Application.
- Step 2: Layer 4, the Transport Layer, manages end-to-end communication between application processes on host devices, providing port addressing, segmenting, flow control, and reliability (TCP).
Answer
Transport layer.
Why not the others: Network layer manages packet routing and IP addressing; Data Link manages frame delivery and MAC addresses; Session establishes dialogue checkpoints.
