What is Web 2.0 technology?
Web 2.0 is the term used to describe a variety of web sites
and applications that allow anyone to create and share online
information or material they have created. A key element of
the technology is that it allows people to create, share, collaborate
and communicate. Web 2.0 differs from other types of websites as it
does not require any web design or publishing skills to participate,
making it easy for people to create and publish or communicate their work to the world. The nature of this technology makes it an easy and popular way to communicate information to either a select group of people or to a much wider audience. The University can make use of these
tools to communicate with students, staff and the wider academic community. It can also be an effective way to communicate and interact with students and research colleagues.
There are number of different types of Web 2.0 applications including wikis, blogs, social networking,
folksonomies, podcasting and content hosting services. Many of the most popular websites are Web 2.0
sites such as Wikipedia, YouTube, Facebook, MySpace, Flickr and more.
A Wiki is a collaborative website that anyone within the community of users can
contribute to or edit. A Wiki can be open to a global audience or can be
restricted to a select network or community. Wikis can cover a specific topic or
subject area. Wikis also make it easy to search or browse for information.
Although primarily text, wikis can also include images, sound recordings and films.

A blog is a contraction of the words web log. Blogs usually provide
commentary or information on a particular issue, event or topic. In some
cases, blogs can be about a particular person, an online, public or personal
diary. A blog is usually maintained by a single person or a small group of
contributors. Visitors to the blog can comment on the entries made or
respond to comments made by other visitors. Blogs are primarily text but
can also be the form of photos or other images, sounds or films.
Social networking allows an individual to create a profile for themselves
on the service and share that profile with other users with similar interests
to create a social network. Users can choose to have public profiles
which can be viewed by anyone or private profiles which can only be
viewed by people that the users allow. Users can usually post
photographs, music and videos on their site. Popular social network
services include Facebook.
Content Hosting Services
Content hosting or content sharing sites allow users to upload content that
they have created for others to view. Two of the most popular of these sites
are YouTube, www.youtube.com for videos and Flickr, www.flickr.com for
photographs. Users can also create an individual profile and list their
favorite photos or videos. Users are able to rate and comment on the videos
or photos posted and provide feedback to the creator and other users.
Copyright infringement is an issue for some of these services as many users
do not upload original content.
