Detailed explanation-1: -The data link layer is an interface between the network and physical layer. It is further subdivided into two modules: Medium Access Control (MAC) and Logical Link Control (LLC). The MAC module plays a critical role in conserving network life by efficiently allocating medium access to the contending nodes.
Detailed explanation-2: -The OSI model consists of seven separate but related layers. The second of these layers is the Data Link layer (DLL), located between the physical layer (first layer) and the network layer (third layer). The Internet consists of many hosts and connected devices known as the nodes and networks known as the links.
Detailed explanation-3: -From a software perspective, the network interface defines how the Ethernet device driver gets packets from or to the network. The physical layer describes the way data is actually transmitted on the network medium. The data link layer defines how these streams of bits are put together into manageable chunks of data.
