Evolution of the Web

1. Web 1.0 (The Static Web):

  • Timeline: Late 1980s to early 2000s.
  • Characteristics:
    • Static HTML pages with basic text and images.
    • Limited user interactivity.
    • Primarily informational websites.
  • Key Technologies: HTML, early forms of CSS.

2. Web 2.0 (The Social Web):

  • Timeline: Early 2000s to mid-2010s.
  • Characteristics:
    • Rise of user-generated content and social media.
    • Increased interactivity and dynamic content.
    • Emergence of blogging, forums, and collaborative platforms.
  • Key Technologies: AJAX (Asynchronous JavaScript and XML), CSS2, JavaScript frameworks (e.g., jQuery).

3. Web 2.5 (The Mobile Web):

  • Timeline: Mid-2000s to present.
  • Characteristics:
    • Mobile responsiveness becomes a priority.
    • Proliferation of smartphones and mobile browsing.
    • Introduction of responsive design practices.
  • Key Technologies: Responsive Web Design, mobile-first development.

4. Web 3.0 (The Semantic Web):
