In networking and communications, the formats, codes and procedures for transmitting a unit of data (frame, packet) from one node to another. Known as a "layer 2 protocol," the data link protocol ...

The transmitted bits are divided into frames, most commonly Ethernet. Layers 1 and 2 are required for every type of communications. For more on this layer, see data link protocol.

Ethernet is a computer networking technology that defines physical and data-link layers of the Open Systems Interconnection (OSI) model. The IEEE 802.3 standard describes these functions in an ...
