Study Notes
What is the Web?
- Refers to the World Wide Web (WWW), a system of interlinked hypertext documents accessed via the Internet.
- Pages contain various formats, such as text, images, audio, and video, interconnected by hyperlinks.
How the World Wide Web Works
- The WWW functions like a vast electronic book, with interconnected pages stored on global servers.
- Hyperlinks enable navigation between different documents and sections within a document.
Key Technologies of the Web
- HTTP (Hypertext Transfer Protocol): Protocol for transmitting data between web servers and browsers, defining message formatting and transmission.
- HTML (Hypertext Markup Language): Standard markup language for creating and structuring web pages using specific tags or elements.
- URLs (Uniform Resource Locators): Addresses that identify resources on the web, specifying location through components like protocol, domain name, and resource path.
History of the World Wide Web
- Invented by Tim Berners-Lee at CERN in 1989, aiming for user-friendly global communication and information sharing.
- First demo of a web server and browser conducted in 1990 at CERN; first web page launched in 1991.
- CERN made WWW technology publicly available in 1993 on a royalty-free basis.
Evolution of the Web
- Web 1.0: Static, focused on providing information; lacked dynamic features and interactivity.
- Web 2.0: Emerged early 2000s, allowing for interactive experiences and user collaboration, underpinning platforms like Airbnb and TikTok.
- Web 3.0: In development, aims for intelligent, decentralized, and user-controlled online spaces.
