The network layer is responsible for adding header information to data packets received from the transport layer to identify the route the packet needs to take to reach its destination. This process is called routing. The physical layer is responsible for transmitting bits over a communication channel. The data link layer provides error-free transmission of data frames between nodes over the physical layer. The transport layer ensures reliable data transfer between end-to-end nodes.
