What is Web 2.0?
The term "Web 2.0" describes the changing trends in the use of
World Wide Web technology and web design that aim to enhance
creativity, communications, secure information sharing,
collaboration and functionality of the web. Web 2.0 concepts have
led to the development and evolution of web culture communities
and hosted services, such as social-networking sites, video
sharing sites, wikis, blogs, and folksonomies.
Web 2.0 websites allow users to do more than just retrieve
information. They can build on the interactive facilities of "Web
1.0" to provide "Network as platform" computing, allowing users
to run software-applications entirely through a browser. Users
can own the data on a Web 2.0 site and exercise control over that
data. These sites may have an "Architecture of participation"
that encourages users to add value to the application as they use
it. This stands in contrast to very old traditional websites, the
sort which limited visitors to viewing and whose content only the
site's owner could modify. Web 2.0 sites often feature a rich,
user friendly interface based on Ajax, OpenLaszlo, Flex or
similar rich media.
The concept of Web-as-participation-platform captures many of
these characteristics. The characteristics of Web 2.0 are: rich
user experience, user participation, dynamic content, metadata,
web standards and scalability. Further characteristics, such as
openness, freedom and collective intelligence by way of user
participation, can also be viewed as essential attributes of Web
The sometimes complex and continually evolving technology
infrastructure of Web 2.0 includes server-software,
content-syndication, messaging-protocols, standards-oriented
browsers with plugins and extensions, and various
client-applications. The differing, yet complementary approaches
of such elements provide Web 2.0 sites with information-storage,
creation, and dissemination challenges and capabilities that go
beyond what the public formerly expected in the environment of
the so-called "Web 1.0".
Universities are using Web 2.0 in order to reach out and
engage with generation Y and other prospective students according
to recent reports. Examples of this are: social networking
websites – YouTube, MySpace, Facebook, Youmeo, Twitter and
Flickr; upgrading institutions’ websites in gen Y-friendly
ways – stand-alone micro-websites with minimal
