Chapter 14 - ISPs and Network Connections

  1. Introduction
  2. Internet Service Providers and Fees
    • A charge for using the Internet (everyone pays this); can be a flat rate or per usage
    • A charge for the connection to the Internet (paid to "phone company" for dedicated connection)
  3. Customer Connections Form the Last Mile
  4. Leased Circuits Are Expensive [$500-5000 USD] (T-1, T-3, etc.)
  5. Most Individuals Choose Dial-Up Access [requires modems]
    Using the conventional telephone system to access the Internet is extremely popular because it is the least expensive access technology.
  6. The Important Concept of Continuous Connectivity (Dedicated Circuit)
    • Usually higher-speed than dial-up
    • Instantaneous access and continous availablity (necessary for a website to be available 24/7)
  7. Instantaneous Access Changes Use
    A dedicated Internet connection that provides instantaneous access 24/7 changes the way an individual views the Internet because it encourages frequent and casual use.
  8. Newer Technologies Offer Inexpensive Dedicated Access
    • Cable Modems (uses existing cable-TV wiring) - shared cable
    • xDSL (Digital Subscriber Line) - uses existing phone lines
    • Wireless - uses cell phone technology
