Web 2.0 represents an important shift in the way digital information is created, shared, stored, distributed, and manipulated.
Web 2.0 pushes computing power off the desktop and onto the Internet, which means less time and money spent on PC software administration. As a general rule, Web 2.0 tools are also less expensive than traditional software — and many are even free. Because they’re Web-based, all you need to get started is an up-to-date browser.
In 1984, Sun Microsystems co-founder John Gage coined the phrase “the network is the computer” to describe his vision for the future of information technology. This was a bold statement at the time. because it anticipated a future in which data networks would be powerful enough to supplant mainframes and desktop PCs as a primary IT resource.
Fast-forward to the present: Though it’s taken more than two decades for the prediction to come true, Web 2.0 is at last turning the network into a vibrant computing platform. Today’s Web-based applications are fast and dynamic, and they behave much like software applications installed on desktop computers. For example, Google Spreadsheets is a spreadsheet tool that works much like Microsoft Excel, with three big differences: It’s Web-based, so users don’t need to download or install any software; it’s collaborative, so multiple users can work on one spreadsheet at the same time; and (best of all) it’s free.
Apart from the concept itself, some specific Web 2.0 technologies are also important to understand. These include:
- Atom: A format for the syndication of online content.
- Blog: Blogs are the backbone of Web 2.0’s democratic spirit.
- Mashups: Websites or applications that combine content from one or more sources. For example,.
- RSS: Shorthand for “Real Simple Syndication,”
- Social media
- Tags: User-generated keywords used to describe online content.
- Wikis: A dynamic Web document that allows users to add, change, or edit the content displayed on the page.
- XML: An abbreviation for “Extensible Markup Language
