What is Web 2.0? - Item 1

A lot of people do not know what Web 2.0 is when it is thrown around today. I've personally asked many people in my spare time who use computers all the time for work purposes and all their answer was, "There's a newer version of the Web now?".

Web 2.0 is often referred to as a read/write Web or a database-backed Web because all information is sent to a database and received from it. Web 2.0 is a reference to many web applications online. These include: 

• Blogs
• Wikis
• Sharing media
• Collaboration 

It is these technologies that help us grab information from somebody else's contribution or giving some ourselves. (e.g. Facebook, basic chat rooms.)

What is the difference between a blog and a wiki?
A blog is short for "Web Log" (e.g. We"b log"). They function as online journals and are usually run by a single owner. This means most of the information is contributed by the owner themselves unless they give other user's permission. A collection of bloggers is called a blogosphere.


A wiki is a collection of searchable, linked web pages that users can create or edit as a community. (e.g. Wikipedia is a collection of Web pages created and edited by users from all over the globe.)
