Explanation

The physical layer exists in the OSI model, but not in the TCP/IP model. The TCP/IP Protocol Architecture Layers are: [1] Application (Determines the protocols for the Transport layer); [2] Transport (Allows for data to move among devices); [3] Internet (Creates and inserts packets); [4] Network Interface (Governs how data will move through the network) (for more on this, see ISC2 Study Guide, Chapter 4, Module 1).
