Then someone opens a textbook with seven boxes while the operating system documentation shows only four.</p> <p>Nothing is necessarily wrong. The team is looking at the same communication through two different maps.</p> <p><strong>The OSI model is a seven-layer reference model for describing network functions. The TCP/IP model—more precisely, the Internet protocol suite architecture—groups communication into four layers built around protocols used on the Internet.</strong> OSI gives you finer vocabulary. TCP/IP follows the structure of a deployed protocol suite.</p>
