For computers to communicate with one another, information has to be bundled and each computer has to have a known address. Think of a post office with many mailbox addresses to serve. How does the post office know to which mailbox to deliver a letter? There is specific information on each letter with zip code, state, city, and street address. It is the same with transferring information from one computer to another. The difference is that, with computers, you use protocols to bundle up the information and send it to the correct computer that needs that information.

The Internet protocol suite is a collection of communications protocols commonly used in networks. Although this suite is commonly known as TCP/IP, these are only two of the many protocols necessary for network communications.

Choose one such protocol to share with the class. Use your post title to identify your chosen protocol so that it is easy for others both to know what your post is about and to scan quickly to identify what protocols have already been explained in the Discussion
