    • A network of networks allowing communication across a wide range of devices
    • The internet has its roots in the 1960s, initially created for government research
    • The ARPANET was a precursor to the internet, using a new communication protocol called TCP/IP to enable different networks to communicate
    • The World Wide Web (WWW) is a collection of information organized as Web pages containing text and images.

    How to Access the Internet?

    • Many schools and businesses have direct access to the internet using special high-speed communication lines.
    • You can use an Internet Service Provider (ISP) to access the internet.

    Client/Server Structure of the Web

    • Web clients are the devices that connect to the internet and use web browsers to access web servers.

    Internet Protocol (IP) Addressing

    • Each computer on the internet has a unique IP address, a four-part number.

    Business Intelligence (BI)

    • A collection of methods, processes, and technologies used to transform raw data into useful information for making better decisions.
    • BI involves data collection, analysis, and visualization

      • Structured, unstructured, and semi-structured data
      • Information overloading
      • Big data
      • Difficulty accessing data
      • Lack of data

    Decision Making in BI
