What is the primary function of the Data Link layer in the OSI model?

Step 1: Understand that the OSI model has 7 layers, and the Data Link layer is the second layer.
Step 2: Know that the main job of the Data Link layer is to prepare data for transmission over a physical medium.
Step 3: Learn that the Data Link layer creates 'frames' which are packets of data that include both the actual data and control information.
Step 4: Recognize that the Data Link layer checks for errors in the data being sent and can correct them if necessary.
Step 5: Remember that the Data Link layer also manages how devices on the same network communicate with each other.
