Difficulty: Medium (Learn More)

The Data Link Layer or the Network Access Layer, one of the five layers in the TCP/IP 5 Layer Model, represent the standards used to communicate between network devices.

The data link layer is responsible for defining a common way of interpreting these signals, so network devices can communicate properly. There are lots of protocols that exist at the data link layer, but the most common is known as Ethernet, although wireless technologies are becoming more and more popular. Beyond specifying physical layer attributes, the standards also define a protocol responsible for getting data to nodes on the same network or link.
