## Question

What is Web2.0? What are the difference between Web1.0 and Web2.0?

## Short answer

Web 2.0 is the read-write, interactive phase of the Web where users create and share content. Key differences from Web1.0: static vs dynamic, user-generated content, two-way communication, AJAX/APIs, tagging, and web as platform (e.g., Wikipedia, Facebook).

## Answer

#### Web 2.0
**Web 2.0** is the second stage of the Web (the term was popularised by Tim O'Reilly in 2004) in which websites focus on user participation, collaboration, sharing and rich interactive experiences. Users are not just readers; they create and share content (blogs, videos, photos, wiki articles). The Web is treated as a platform, with services delivered through browsers using AJAX, RSS, APIs and mashups.

Key features: user-generated content, social networking, collective intelligence, rich user interface, tagging, open APIs, and "perpetual beta" software. Examples: Facebook, YouTube, Wikipedia, Flickr, Twitter, Blogger.

| Basis | Web 1.0 | Web 2.0 |
|---|---|---|
| Nature | Read-only, static pages | Read-write, interactive |
| Content | Created by webmasters | User-generated |
| Communication | One-way | Two-way, social |
| Technology | HTML, CGI | AJAX, XML/JSON, RSS, mashups |
| Software | Desktop applications | Web applications (Web as a platform) |
| Classification | Directories | Tagging and folksonomy |

| Revenue | Banner ads, selling products | Targeted ads, subscriptions, services |
