The lowest layers of the OSI model are: the Physical and Data Link layers. These layers specify standards for the computer’s interaction with the physical transmission media. As the network administrator, you should understand what each layers does.

Devices, protocols, and programs that run at the network layer are responsible for identifying, selecting, and directing traffics through the internetwork.

OSI model is the most widely used method for describing network communication.

OSI model divides networking tasks into the following seven layers.
