Which of the following statements about the OSI

Solution

The Transport Layer (Layer 4) of the OSI model is responsible for providing end-to-end communication, ensuring reliable data delivery, and managing flow control between devices. It uses protocols like TCP and UDP to establish logical communication between processes, handle error detection, and ensure that data is delivered in the correct sequence. This layer also controls the flow of data to prevent congestion. Option A (Defines data formatting): Data formatting is done at the Presentation Layer (Layer 6), not the Transport Layer. Option B (Ensures reliable data transfer): While the Transport Layer does provide reliable data transfer (e.g., using TCP), error detection and correction are done at both the Data Link (Layer 2) and Transport Layer, not solely at Layer 4. Option C (Routing data): Routing is the responsibility of the Network Layer (Layer 3), which is concerned with the logical addressing and forwarding of packets across networks. Option E (Logical addressing): Logical addressing is handled by the Network Layer (Layer 3) using IP addresses, not the Transport Layer.
