Data Link Communications

Data link communication refers to the process of transmitting information between two devices over a dedicated communication channel. It involves establishing a reliable connection, framing data into manageable units, and ensuring accurate delivery through error detection and correction. This layer manages how devices access the shared medium, coordinates data exchange, and maintains synchronization. In essence, data link communication is responsible for the dependable transfer of data between nearby devices, such as computers or networking hardware, forming the foundation for more complex network interactions.
