What is WIKI?

I suppose everyone's heard about wiki. Wiki is a web technology used for collaborative publishing on the web. The well-known example of wiki is Wikipedia.

A group of co-authors can freely add and change information on the wiki website: rewrite texts, add images, new texts, links etc. The wiki owner can restrict editing to a group of collaborators.

Unlike other publishing platforms wikis are:

• Heavily based on collaboration
• Non-linear and not based on time
• Are purely content-oriented

Wiki sites can be:

1) Encyclopedias (like I said, Wikipedia)

2) Corporate wikis are used to train new employees and harness the power of corporate synergy

3) Fan wiki sites are sites dedicated to specific field that excites a group of people (The Elder Scrolls Wiki) 

4) Educational wikis are mainly collective research projects. Focused around focused-oriented issues, these projects are typically developed by students and moderated by their teachers.

Free wiki tools:

• Wikispaces
• Wikia
• Zohowiki
• Wiki site
• WikiDot

As for me, I use wikis very often. Wikipedia helpes me to search useful information for my reports, essays and even when I want to know more about some questions. Such sites have advantages over the ordinary ones, 'cause it refers to a great number of authors. Information of wikis can be updated and that's a significant advantage.
