the main processes of the data link layer are to deal with transmission errors, regulate the flow of data, and provide a well-defined interface to the network layer.

The data link layer links the other layers of the OSI model together, so that the end to end devices are able to communicate with each other. More so to ensure that network errors do not occur, with your internet line

Detailed explanation-1: -The data link layer has three main functions: It handles problems that occur as a result of bit transmission errors. It ensures data flows at a pace that doesn’t overwhelm sending and receiving devices. It permits the transmission of data to Layer 3, the network layer, where it is addressed and routed.
Detailed explanation-2: -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-3: -Data-link layer: This layer is responsible for moving frames from one hop to next. The Data-link layer divides the stream of bits received from the network layer into manageable units called frames.
