  • Chapter 6, Telecommunications and Networks, describes basic concepts and components of networks used for data communications. After studying chapter 6, you should be able to address the learning objectives described in the following 2 slides.
  • Transcript

    • 1. Telecommunications and Networks Chapter 6
    • 2. Principles and Learning Objectives <ul><li>Effective communication is essential to organizational success. </li></ul><ul><ul><li>Define the terms communication and telecommunications and describe the components of a telecommunications system. </li></ul></ul>
    • 3. Principles and Learning Objectives <ul><li>An unmistakable trend of communications technology is that more people are able to send and receive all forms of information over greater distances at a faster rate. </li></ul><ul><ul><li>Identify three basic types of communications media and discuss the basic characteristics of each. </li></ul></ul><ul><ul><li>Identify several types of telecommunications hardware devices and discuss the role that each plays. </li></ul></ul><ul><ul><li>Identify the benefits associated with a telecommunications network. </li></ul></ul><ul><ul><li>Name three distributed processing alternatives and discuss their basic features. </li></ul></ul><ul><ul><li>Define the term network topology and identify five alternatives. </li></ul></ul>
    • 4. Principles and Learning Objectives <ul><li>The effective use of telecommunications and networks can turn a company into an agile, powerful, and creative organization, giving it a long-term competitive advantage. </li></ul><ul><ul><li>Identify and briefly discuss several telecommunications applications. </li></ul></ul>

    • 10. Basic Communications Channel Characteristics <ul><li>Simplex channel </li></ul><ul><li>Half-duplex </li></ul><ul><li>Full-duplex channel </li></ul>
    • 11. Bandwidth <ul><li>The range of frequencies that an electronic signal occupies on a given transmission medium. </li></ul>
    • 12. Broadband <ul><li>Telecommunications in which a wide band of frequencies is available to transmit information, allowing more information to be transmitted in a given amount of time. </li></ul>
    • 13. Shannon’s Fundamental Law of Information Theory <ul><li>The information carrying capacity of a channel is directly proportional to its bandwidth - the broader the bandwidth, the more information that can be carried. </li></ul>
    • 14. Types of Media <ul><li>Twisted-Pair </li></ul><ul><li>Coaxial Cable </li></ul><ul><li>Fiber-Optic Cable </li></ul><ul><li>Microwave Transmission </li></ul>
