What the OSI model does is allow all users of the network to see the operation between layer and layer, this makes it easier for us to know and in this way learn how everything travels within a network, the ways of communication in them etx... In addition to this, this OSI model is used to visualize the data, from basic application programs that we use daily through a network. Taking the above into consideration, develop a Waterfall Model that shows the communication between all the layers of the OSI Model that contribute to the development of Network communications.
