    Study Notes

    Extranets

    • Extranets provide secure access to organizational networks for users from other organizations, enabling data sharing.

    Internet Access Technologies

    • Various methods connect users and organizations to the Internet, including broadband cable, DSL, wireless WANs, and mobile services.
    • Organizations require faster connections to utilize IP phones, video conferencing, and data centers effectively.
    • Business-class interconnections, such as business DSL, leased lines, and Metro Ethernet, are typically provided by service providers.

    Home and Small Office Internet Connections

    • Cable: Offers a high-bandwidth, always-on Internet connection through cable television providers.
    • DSL: Provides a high-bandwidth, always-on Internet connection via telephone lines.
    • Smart home technology integrates with everyday appliances, allowing devices to communicate (e.g., ovens coordinating cooking times with calendars).

    Powerline Networking

    • Powerline networking enables LAN connections where traditional data cables or wireless signals are unfeasible, using electrical outlets to transmit data signals.

    Wireless Broadband

    • Wireless Internet Service Providers (WISPs) offer connections mainly in rural areas, linking users to designated access points.
    • Wireless broadband utilizes cellular technology, delivering high-speed bandwidth to devices within a network.

    Wide Area Networks (WANs)

    • WANs connect multiple LANs over vast geographical areas (cities, states, countries) and are managed by multiple service providers.
    • They usually offer slower speed links compared to LANs.

    The Internet Overview

    • The Internet is a global network of interconnected LANs and WANs, linking them through various transmission methods (copper wires, fiber optics, wireless).
    • Not owned by any entity, it has several organizations maintaining structure:
      • IETF: Internet Engineering Task Force
      • ICANN: Internet Corporation for Assigned Names and Numbers
      • IAB: Interactive Advertising Bureau

    Intranets and Extranets

    • An intranet is a private network of LANs and WANs restricted to an organization’s members or authorized users, contrasting with the open nature of the Internet.
