Nt1210 LAB3 3.1: Networking models Review: The two networking models are TCP/IP which had 5 different layers and the OSI model which has 7 layers. They mainly incorporate the same layers and the only difference is that the TCP/IP layer combines layers 5‚ 6 and 7 all into layer 5. Both models are along the same line of information and both explain how a network moves data. 3.2: OSI reference model: The OSI model includes two more layers that the TCP/IP layer already had but is constructed in

Vance Campbell NT1210 – Intro to Networking Lab 3.1 to 3.4 3.1 1. Why would a three-layer model of communication that has the layers physical‚ network‚ and application be insufficient to adequately describe network communication? A. Because there is no transport or application layer. 2. What is the history of the OSI reference model? How did it come about and why was it created? Use your textbook and Internet research to support your answer. A. It was created to standardize the way
