How many layers are in the OSI and TCP/IP models, respectively?
7/5
Name the layers of the OSI model.

What two documents present and detail the use of the TCP/IP model?

There are two forms of communication described in both standards. These forms are predominantly part of Layers 3 and 4. What are they?
Connection mode (oriented) and connectionless-mode
Network administrators typically have the ability to use whatever protocols they wish, regardless of the layer in question. True or false?
One big difference between the documentation of the TCP/IP and OSI standards is that the TCP/IP RFC specifies the protocols to be used and the OSI ITU-T model documentation does not. True or False?
