Web 2.0 is the term given to describe a second generation of the
World Wide Web that is focused on the ability
for people to collaborate and share information online. Web 2.0 basically refers
to the transition from static
HTML Web pages to a more
dynamic Web that is more organized and is based on
serving Web applications to users.
Other improved functionality of Web 2.0 includes open communication with an
emphasis on Web-based communities of users, and more open sharing of
information. Over time Web 2.0 has been used more as a marketing term than a
computer-science-based term.
Blogs, wikis, and
Web services are all seen as components of Web
2.0.
Web 2.0 was previously used as a synonym for
Semantic Web, but while the two are similar, they do not share precisely the same
meaning.
