Defining the Internet Defining the Web Defining Web 2.0 Technologies Websites Applications Library 2.0
The Internet (from Wikipedia) The Internet is a global system of
interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.
It is a network of networks that consists of millions of private, public, academic, business, & government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies.
The World Wide Web (from Wikipedia) The Web is a system of interlinked
hypertext documents accessed via the Internet.
With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks.
Tim Berners-Lee and his team originated the WWW.
Web 2.0 Who coined the phrase? Tim O’Reilly of
O’Reilly Media and MediaLive International
Web 2.0 applications are built for user-added content
Before, a web manager added content to a website but the exchange was one-way
Today, anyone with Internet access can add content to a Wiki, Blog or other social networking site
Web1.0 vs Web2.0 Term Web2.0 suggests a new version of the Web,
but actually it does not refer to an update to any technical specifications. Rather it refers to cumulative changes in the ways software developers and end-users use the Web.
It is the difference betw Britannica online and Wikipedia
In Web 1.0 content was written, edited and published by a select group of people much the same way books are published.
In Web 2.0 anyone can add to the collective pool of knowledge and anyone can access it.
Web 2.0 Applications can run on mobile devices, not only PCs
O’Reilly quote:“A core concept of Web 2.0 is that peoplepeopleare the content of sitesare the content of sites. That is, a site is notpopulated with information for users toconsume. Instead, services are provided toindividual users for them to build networks offriends and other groups (professional, recreational, etc.).
