    Study Notes

    Basic Concepts of the Internet and the World Wide Web

    • The internet is a vast computer network connecting billions of devices globally, making everyday tasks easier. Appropriate usage relies on individual needs and goals.
    • Objectives include understanding internet and World Wide Web concepts, history, standards bodies (like W3C), and web application development.

    What is the Internet?

    • The internet is a network of networks, decentralized in design.
    • Key components include computers/hosts (devices accessing information), servers (specialized hardware handling requests), routers/switches (routing internet traffic), and communication channels (phone lines, cable, satellite, wireless).
    • Bandwidth refers to data transmission capacity, usually measured in bits per second (bps).
    • Transmission Control Protocol/Internet Protocol (TCP/IP) is crucial for formatting, ordering, and error-checking data transmission across networks.

    Internet Addresses and the Web

    • Every device connected to the internet has a unique IP address (e.g., 192.168.4.2).
    • Domain Name System (DNS) translates IP addresses into human-readable domain names (e.g., www.google.com).

    Client-Server Architecture

    • The internet follows a client-server model.
    • Clients request information, servers respond with the requested data.
    • Web browsers (e.g., Firefox, Chrome) are client software, while web servers handle client requests.
    • Electronic mail also follows client-server model, using client software such as Gmail or Thunderbird and server software (mail server).

    Packet Switching

    • Packet switching is the fundamental data transfer method on the internet.
    • Data is broken down into packets with source and destination addresses.
    • Packets may travel different routes to reach the destination, and are reassembled afterward.

    History of the Internet and the World Wide Web

    • In 1945, Vannevar Bush discussed Memex, envisioning a system for organizing and accessing information.
    • Ted Nelson conceptualized hypertext and Xanadu which were important ideas for the World Wide Web.
    • The Advanced Research Projects Agency (ARPA) initiated the ARPANET in 1969 during the Cold War.
    • The development of TCP/IP, DNS, emails (SMTP), and FTP is credited to ARPANET.
    • Tim Berners-Lee created the World Wide Web (WWW) in 1990 to facilitate information sharing among researchers.

    Explosive Growth of the Internet

    • Internet penetration has rapidly increased due to factors such as improved bandwidth, reduced government regulations, and cost-effective connection options.

    The World Wide Web (WWW)

    • The World Wide Web is a system of hypertext-based documents accessible via the internet.
    • Hypertext Markup Language (HTML) defines content structure (e.g., headings, paragraphs).
    • Hypertext Transfer Protocol (HTTP) is the protocol behind website communication.
    • Mosaic was one of the first web browsers.

    Anatomy of a Website

    • Uniform Resource Locator (URL) identifies specific web pages (e.g., www.example.com/page.html).
    • Every webpage has a server and a path.
    • Web servers host web pages and related files.

    Web Standards and Bodies

    • Web standards create essential guidelines for building accessible and compatible web pages.
    • Important organizations that create and maintain standards include: IETF, W3C, WHATWG, and ECMA TC39.
    • Standards contribute to compatibility, accessibility, and maintainability.
