The World Wide Web (WWW)

  • The Web is an information system where documents and other resources are identified by URLs (e.g., https://example.com) and linked via hypertext/hypermedia, accessible over the Internet.
  • Tim Berners-Lee is the inventor (Father) of the Web.

The Web’s core idea

  • The Web provides access to a vast array of documents connected by hyperlinks; web browsers view and navigate these linked resources.
  • Hypertext lets users select a word or phrase to access related information elsewhere; hypermedia links also link to images, sounds, animations, and movies.
  • The Web operates on a client-server model: servers store and transmit documents; clients request documents; browsers retrieve and display content.

Tim Berners-Lee and the Web’s origins

  • Invented the Web in 1989 while at CERN.
  • Worked to ensure it would be freely available to all.
  • Recognized as a visionary innovator and one of Time Magazine’s “100 Most Important People of the 20th Century.”

Web 1.0: The Static Web

  • Most pages were static and non-interactive; Web 1.0 is the first stage of the Web.
  • Web 1.0 is also referred to as the Static Web (Web 1.0).

Web 1.0 characteristics and impact

  • Static web pages: content rarely updated; web resembled a digital library rather than an interactive space.
  • Basic functionality: pages largely contained text and images with limited interactivity or multimedia.
  • Curated content: webmasters curated content; users were passive consumers.
  • Slow adoption: limited home Internet access in early to mid-1990s; widespread adoption occurred late 1990s to early 2000s.
  • Limited e-commerce: online shopping was limited due to security/privacy concerns; mainstream online shopping emerged with Web 2.0.
  • Limited social interaction: interactions were primarily with content rather than with other users.

Web 2.0: The Social Web

  • Web 2.0 emerged in the early 2000s and marks a shift to user-generated content and dynamic, interactive experiences.
  • Characteristics: dynamic pages, user contributions, comments, and feedback.
  • Examples: social networks (Facebook, Myspace, Twitter, LinkedIn), blogs (WordPress, Blogger, Medium), wikis (Wikipedia), video sharing (YouTube), podcasts (SoundCloud), e-commerce (Etsy, eBay).
  • Impact:
    • Democratization of publishing: anyone with Internet can publish content.
    • Rise of participatory culture: everyone can collaborate and share.
    • Blurring of producer/consumer lines: users can both create and consume content (prosumer).
    • Increased connectivity and sharing: easier to connect and share information and media.
    • New forms of work and business: startups, new business models, and digital marketing emerged.

Key Features of Web 2.0

  • Folksonomy: user-generated tagging with free keywords; hashtags (e.g., #tag) for categorization.
  • Rich User Interface: dynamic content responding to user input; personalized local content on social networks.
  • User Participation: others can contribute through comments, reviews, and evaluations.
  • Long Tail: services offered on demand; subscriptions or usage-based models rather than one-time purchases.
