Describe the Internet/DOD Model in detail as described in the textbook for the course (FitzGerald and Dennis). List each layer in order from top to bottom including the various functions that each layer performs. How does that compare to the OSI model? Identify typical protocols used at each layer of the Internet model and describe the process of what happens when a user creates and sends an email using a client such as MS Outlook. How is this different than when a web browser is used to access email? Describe that process.
