Explanation: The Data Link layer attaches a trailer to the end of a packet and includes a header. The trailer typically contains error detection and correction information, while the header contains information about the source and destination of the packet. The Data Link layer is responsible for delivering packets over a single link of a network, such as a local area network (LAN), and it is one of the two layers of the OSI model that make up the network interface layer. The other layer is the Physical layer, which is responsible for transmitting bits over a physical medium.
