Question
Which layer in the OSI model is responsible for
end-to-end communication and error-free delivery of data between hosts?Solution
The transport layer (Layer 4) is responsible for ensuring reliable data transfer between two hosts. It manages flow control, segmentation, error detection, and retransmission of lost data packets, ensuring that data is delivered correctly. Why Other Options are Wrong: a) Physical layer handles the transmission of raw data. b) Data link layer provides error detection and correction within a single network. d) Network layer handles routing and logical addressing, not end-to-end communication. e) Application layer interacts directly with end-user applications but doesn’t handle data transmission.
