Web versions; Web 2.0 versus Web 3.0
Short answer
Web2.0 emphasizes user-generated content and social interaction on centralized platforms. Web3.0 focuses on machine-readable data (semantic web) and decentralization via blockchain, enabling intelligent, user-owned applications.
Explain the web version in detail and differentiate between Web 2.0 and Web 3.0.
Web versions
- Web 1.0 (about 1991-2003) – read-only web: Static HTML pages published by a few authors; users only read. Hyperlinks, directories, early search engines. Little interaction.
- Web 2.0 (2004 onward) – read-write, social web: Users create content through blogs, wikis, social networks and video sharing. Uses AJAX, RSS, APIs and cloud services. Platforms are centralised and owned by large companies (Google, Facebook, YouTube).
- Web 3.0 – two views:
- Semantic Web (Tim Berners-Lee): data given machine-readable meaning (RDF, OWL, ontologies) so computers can understand and combine information; intelligent agents and personalised search.
- Decentralised web: blockchain, cryptocurrencies, smart contracts and user-owned data, together with AI and 3D/immersive experiences.
- Web 4.0 / Web 5.0 (emerging): Proposed ideas of an intelligent "symbiotic" web with AI assistants and IoT; not standardised.

Web 2.0 versus Web 3.0
| Basis | Web 2.0 | Web 3.0 |
|---|---|---|
| Focus | User-generated content and social interaction | Meaning of data, intelligence and decentralisation |
| Data | Understood by humans only | Machine-understandable (semantic) |
| Control | Centralised by big companies | Decentralised, user ownership (blockchain) |
| Technology | AJAX, XML, RSS, APIs, cloud | RDF, OWL, AI, blockchain, smart contracts |
| Search | Keyword-based | Context- and meaning-based, personalised |
| Examples | Facebook, YouTube, Wikipedia | Ethereum-based apps, semantic search, smart assistants |
