Read Chapter 1: An Introduction to Networking (up to the Chapter Summary) in CompTIA Network+ N10-005 In Depth and the document The OSI Model’s Seven Layers Defined and Functions Explained for a brief explanation of the OSI model, including a mnemonic that may help you remember the different layers of the OSI and their roles.
Consider the types of communication that can occur over a network. Pay attention to the difference between peer-to-peer networks and client-server networks. Note the different types of network topologies and how data is transmitted.
After reviewing these resources, discuss the following:
- Discuss differences in various network types (i.e. peer-to-peer, client-server, etc.)
- Be creative and come up with an analogy to explain network communication to your friends/family who do not understand basic networking.
Example network analogy: DNS servers behave like telephones do when we type in a number that we have in our contact list. If the phone number matches that of one of our contacts, the phone shows the name of the individual rather than his or her phone number. Also, you can simply click on a name in your contacts list, and the phone will dial the correct corresponding number.
