This lab will help to develop a better understanding of the seven layers of the OSI model. Specifically as they relate to the most popular functioning networking model in existence, the TCP/IP model. The Internet is based on TCP/IP. TCP/IP has become the standard language of networking. However, the seven layers of the OSI model are the ones most commonly used to describe and compare networking software and hardware from various vendors. It is very important to know both models and be able to relate or map the layers of one to the other.

Relate the seven layers of the OSI model to the four layers of the TCP IP model. Name the primary TCP IP protocols and utilities that operate at each layer. Background This lab will help to develop a better understanding of the seven layers of the OSI model. Specifically as they relate to the most popular functioning networking model in existence the TCP IP model. The Internet is based on TCP IP. TCP IP has become the standard language of networking. However the seven layers of the OSI model are the ones most commonly used to describe and compare networking software and hardware from various vendors. It is very important to know both models and be able to relate or map the layers of one to the other. An understanding of the TCP IP model and the protocols and utilities that operate at each layer is essential when troubleshooting. Steps 1. Use the table below to compare the OSI layers with the TCP IP protocol stack. In column two indicate the proper name for each of the seven layers of the OSI model corresponding to the layer number. List the TCP IP layer number and its correct name in the next two columns. Also list the term used for the encapsulation units the related TCP IP protocols and utilities that operate at each TCP IP layer. More than one OSI layer will be related to certain TCP IP layers.
