Think of a wiki as a website with a collection of pages that any of the wiki members can edit; each change is recorded, with every version saved so that if a mistake is made, you can just revert back to a previous version. It is possible to see which users made any changes. Common Craft have a video explaining the idea of a wiki. It is possible to lock individual pages so that members cannot edit them.
