Tutorial: The OSI Reference Model for Network Protocols

Learn how network protocols work by studying the OSI reference model. Includes a correlation between TCP/IP and the OSI reference model.

Here is a snippet: "OSI is a model that is used to understand how network protocols work. Usually when we are studying how networks work this is one of the first topics on the study guide. The problem, however, is that usually people don't understand why this model exists nor how it really works - even people that memorized the names of all the seven layers of this model to take an exam at college or a certification exam still have no clue. In this tutorial we will explain you why the OSI model exists and how it works and we will also present a quick correlation between TCP/IP and the OSI model."
