Quizplus · Accepted Answer

The physical layer is responsible for transmitting and receiving data over communication channels, including the physical aspects of cables, connectors, and transmitters. It deals with the transmission of raw bits and doesn't concern itself with interpreting the data. The data link layer, on the other hand, adds error checking and control information to each packet to ensure correct transmission, making it responsible for reliable and error-free data transfer. The application layer deals with the presentation of the data to the user and the network layer is responsible for routing data between different networks.
