    Study Notes

    Introduction to Computer Networks

    • Computer networks are interconnections of geographically distributed computers that facilitate information exchange.
    • The primary objectives of a computer network are sharing information, resources (hardware and software), and processing load.

    Internet

    • The internet is a massive global network of computers and other electronic devices.
    • It comprises networks scattered worldwide, connecting various computer types across continents using satellite and telephone lines.

    Internet Connectivity Methods

    • Dial-up Connection:
      • A temporary connection between a computer and an Internet Service Provider (ISP) server.
      • Requires a computer, modem, and an ISP account.
      • Analog connection that uses the public telephone network.
      • A modem converts analog data to digital and vice-versa.
      • Users dial an ISP's telephone number and provide their username and password.

    World Wide Web (WWW)

    • The WWW is a repository of information spread globally, linked together using hyperlinks.
    • It was created in 1989 at the European Particle Physics Laboratory in Geneva, Switzerland.
