Procedure: I. Internet Standards To familiarize yourself with the Internet Standards, search the Internet for the IETF RFC website. Using the information you find on this site, answer the following questions:
a. Identify four types of Internet standards. (Hint: See RFC 2026)
b. Compare and contrast two of the RFC types you identified.
c. What is IAB?
II. RS-232 Communications In this section, we look at transmission of ASCII characters using (RS-232) binary asynchronous serial format.
a. Given a digital multi-meter and an RS-232 cable, describe the measurements you make to determine whether the cable is a NULL modem cable or not.
b. The following waveform represents the signal that appears on RS-232 output pin when the ASCII character: e is sent. What is the ASCII code for e?
a) Show the corresponding waveforms that you would see for the following ASCII characters: Waveform for ASCII Character: ? Waveform for ASCII Character: 4 Waveform for ASCII Character: y Waveform for ASCII Character: % Waveform for Character: A
b) How are upper- and lower-case letters distinguished in the ASCII character set?
c) What are the signal names and purpose of the RS-232C lines in the cable?
III. Cables and Connectors
a) Compare and contrast UTP and STP cables.
b) Provide a brief description and use of at least three examples each of coaxial, RJ, and Optical connectors.
Explanation / Answer
4. How Does the Internet Work?
While it is not necessary to understand how the Internet works in order to use it, a brief technical overview will introduce you to some concepts and terms that will be used in the sections ahead. As we go into more detail here, we are assuming that you, the reader, have at least a passing familiarity with computers. Section 6.2 provides more information on computer hardware and software. On one level, networks are built out of wires, phone lines, and other pieces of hardware, and the Internet is indeed built of all these things. The essence of the Internet however is built out of an idea called the Internet Protocol.
