Network Models

There are several network models which you may hear about but the one you will hear about most is the ISO network model described below. You should realize, however that there are others such as:

• The internet layered protocol
• The TCP/IP layered protocol
• The Microsoft networking protocol

If you don’t like any of these models, feel free to invent your own along with your own networking scheme of course, and add it to the list above. You can call it “The MyName Protocol”. Ever wonder why networking can be so complex and confusing? Welcome to the world of free enterprise!
