at network are you examining? What is flowing? What are the different forms of the object that is flowing? What are the rules for flow? Where does the flow occur? The networks listed in this chart give you more analogies to help you understand computer networks. Another example of how you might use the concept of layers to analyze an everyday subject is to examine human conversation. When you create an idea that you wish to communicate to another person, the first thing you do is choose how you want to express that idea, then you decide how to properly communicate it, and finally, you actually deliver the idea. Imagine a young boy seated at one end of a very long dinner table. On the other end of the table, quite a distance away, sits the young boy's grandmother. The youngster speaks English. The grandmother prefers to speak Spanish. The table has been set with a wonderful meal that the grandmother has prepared. Suddenly the young boy shouts at the top of his lungs, "Hey, you! Give me the rice!" and reaches across the table to grab it. In most places, this action is considered quite rude. What should the young boy have done to communicate his wishes in an acceptable manner? To help you find the solution to this question, analyze the communication process by using layers. First there is the idea the young boy wants rice; then there is the representation of the idea spoken English (instead of Spanish); next is the method of delivery "Hey, you"; and finally, the medium shouting (sound) and grabbing (physical action) across the table for the rice. From this group of four layers, you can see that three of them prevent the young boy from communicating his idea in an appropriate/acceptable manner. The first layer (the idea) is acceptable. The second layer (representation), using spoken English instead of Spanish, and the third layer (delivery), demanding instead of a politely requesting, most definitely do not follow acceptable social proto...
