A Wiki is a collaborative Web site that allows users to create, add to, modify, or delete the Web site content via their Web browser. Most wikis are open to modification by the general public. Wikis ususally collect recent edits on a Web page so that someone (like the moderator or owner of the wiki) can review them for accuracy.
But you might be thinking - we can already collaborate on a document online using e-mails! If you look at the next image, you will understand why using wikis is a more efficient and quicker way to write collaboratively. All the information is stored at a central location. No more e-mailing everybody after a tiny update.
Alright then, what about blogs? Can't we collaborate using blogs as well? Well, the difference between a wiki and a blog is that users cannot modify original posts made by the blogger. In a wiki, provided you have the necessary permissions, you can practically edit and change anything on the wiki. However, the older versions of the same document will be stored in database, just in case somebody is spamming the wiki and we need to revert to the previous versions.
A popular wiki is Wikipedia, a free Web encyclopedia. You can obtain more information about wikis at this Wikipedia Wiki page.
Just to get you acquainted with the wiki software, you will go to this trial-scsj wiki to personally experience what you can do in a wiki. Spend some time to familiarize yourselves to the user interface and start editing this wiki to your heart's content!
