Explanation:
Different protocols have different functionalities. The OSI model is
an attempt to conceptually describe where these different functionalities take place
in a networking stack. The model is basically trying to draw boxes around reality
for people to better understand the stack. Each layer has specific functionality and
several different protocols that can live at that layer and carry out that specific
functionality.
