What is web2.0 ?•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 & communicate. • Web 2.0 is the network as platform (Cloud

computing), spanning all connected devices.• Web 2.0 differs from other types of websites as it does not

require any webdesign or publishing skills to participate, making it easy for people to create and publish or communicate their work to the world .

6

• 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.• Example : The University can make use of these tools to

communicate withstudents, staff and the wider academic community. It can also be an effective way to communicate and interact with students and research colleagues.

7

WEB 2.0 & CLOUDS• Web 2.0 concentrate on the private user and clouds are descendants' of data centers which service the Enterprise.• However Web 2.0 promoted SaaS which is part of the cloud.• Web 2.0 companies needed massive scaling technologies which promoted cloud (Amazon).• User centric Web2.0 companies (Twitter, Slide Share) are relaying on Cloud Service.

8

WEB 2.0 FEATURES •Search: the ease of finding information through keyword

searching.

•Links: guides to important pieces of information. -The best pages are the most frequently linked to.

•Authoring: The ability to create constantly updating content that is co-created by users.

-In wikis, the content is iterative in the sense that the people undo and redo each other’s work.

-In blogs, it is cumulative in that posts and comments of individuals are accumulated over time.

9

•Tags: Categorization of content by creating tags that are simple, one-word descriptions to facilitate searching and avoid having to fit into rigid, pre-made categories.

•Extensions: Automation of pattern matching for customization by using algorithms (i.e. Amazon.com recommendations).

•Signals: The use of RSS (Real Simple Syndication) technology to create a subscription model which notifies users of any content changes.

BLOGS

• Blog stands for Web Blog.• The term web-log, or blog, was coined by Jorn Barger

in 1997 and refers to a simple webpage consisting of brief paragraphs of opinion, information, personal diary entries, or links, called posts.

14

•Most blogs also allow visitors to add a comment below a blog entry.•Each post is usually ‘tagged’ with a keyword or two, allowing the subject of the post to be categorized within the system so that when the post becomes old it can be filed into a standard, theme-based menu system.•Clicking on a post’s description will take you to a list of other posts by the same author on the blogging software’s system that use the same tag.

15

• Linking is also an important aspect of blogging as it deepens the conversational nature of the blogosphere and its sense of immediacy. • It also helps to facilitate retrieval and referencing of

information on different blogs.• The large number of people engaged in blogging has

given rise to its own term – blogosphere – to express the sense of a whole ‘world’ of bloggers operating in their own environment.

PODCAST• A podcast is made by creating an MP3 format audio file (using a voice recorder or

similadevice),uploading the file to a host server, and then making the world aware of its existence through the use ofRSS (see next section).• This process (known as enclosure) adds a URL link to the audio file, as well as

directions to the audio file’s location on the host server, into the RSS file (Patterson, 2006).• Podcast listeners subscribe to the RSS feeds and receive information about new

podcasts as theybecome available.• Distribution is therefore relatively simple. • The harder part, as those who listen to a lot of podcasts know, is to produce a good

quality audio file. Podcasting is becoming increasingly used in education and recently there have beenmoves to establish a UK HE podcasting community.

19

WIKI• Wikipedia is a free encyclopedia, written

collaboratively by the people who use it.- It is a special type of website designed to make collaboration easy, called a wiki.• Wiki pages have an edit button displayed on

the screen and the user can click on this to access an easy-to-use online editing tool to change or even delete the contents of the page in question.•Unlike blogs, wikis generally have a history function, which allows

previous versions to be examined, and a rollback function, which restores previous versions.Proponents of the power of wikis cite the ease of use of the tools, their extreme flexibility and open access as some of the many reasons why they are useful for group working.•Many people are constantly improving Wikipedia, making thousands of changes per hour.
