Let’s just talk about this… You have just purchased a new automobile for your personal use. driving the car for a week or so, you find that it is not working correctly. discussing the problem with several of your peers, you decide to take it to an automotive repair facility that they highly recommend. It is the only repair facility located in close proximity to you. When you arrive at the repair facility, you find that all of the mechanics speak another language. You are having difficulty explaining the automobile’s performance problems, but the repairs really need to be done. You are not sure you can drive it back home to research other options. You must find a way to work with the repair facility to ensure that your automobile is fixed correctly. How will you communicate with the mechanics in this firm? Design a communications to ensure that the car is properly repaired. 3.1.1.1 What is Communication? Rules of Communication The Rules A network can be as complex as devices connected across the Internet, or as simple as two computers directly connected to one another with a single cable, and anything in-between. Networks can vary in size, shape, and function. However, simply having the physical connection between end devices is not enough to enable communication. For communication to occur, devices must know “how” to communicate. People exchange ideas using many different communication methods. However, regardless of the method chosen, all communication methods have three elements in common. The first of these elements is the message source, or sender. Message sources are people, or electronic devices, that need to send
Standards organizations include: The Internet Society (ISOC) The Internet Architecture Board (IAB) The Internet Engineering Task Force (IETF) The Institute of Electrical and Electronics Engineers (IEEE) The International Organization for Standardization (ISO) Each of these organizations will be discussed in more detail in the next couple of pages.

ISOC facilitates the open development of standards and protocols for the technical infrastructure of the Internet, including the oversight of the Internet Architecture Board (IAB). The Internet Architecture Board (IAB) is responsible for the overall management and development of Internet standards. The IAB provides oversight of the architecture for protocols and procedures used by the Internet. The IAB consists of 13 members, including the chair of the Internet Engineering Task Force (IETF). IAB members serve as individuals and not representatives of any company, agency, or other organization. The IETF’s mission is to develop, update, and maintain Internet and TCP/IP technologies. One of the key responsibilities of the IETF is to produce Request for Comments (RFC) documents, which are a memorandum describing protocols, processes, and technologies for the Internet. The IETF consists of working groups (WGs), the primary mechanism for developing IETF specifications and guidelines. WGs are short term, and after the objectives of the group are met, the WG is terminated. The Internet Engineering Steering Group (IESG) is responsible for the technical management of the IETF and the Internet standards process.
