What would happen if wireless devices were not governed by the Wi-Fi Alliance and each vendor had its own standards and protocols? What impact would this have on your personal life or business communications?

3. Given the purpose of each, is it necessary to retain the top three layers of the OSI model as separate entities? Use your textbook and internet research to justify your answer.
It is not necessary to keep the top three layers of the OSI model when TCP/IP combines the top three layers of OSI into one layer that ultimately does the same functions.
Using your textbook and internet research, create a mapping between the TCP/IP model and the OSI reference model. What are the distinct differences between them?
One major difference between OSI and TCP/IP is the first three layers of OSI are combined into a single layer in TCP/IP known as the Application Layer. The other difference is the last two layers, Data link and Physical layer are combined into one layer known as Network Access or Link Layer.
Identify the layer in which each protocol resides according to the TCP/IP model.
OSI Layer Name
TCP/IP Layer Name
FTP, HTTP, POP3, IMAP, telnet, SMTP, DNS, TFTP
