What is Wiki ?
Refers to any page or collection of pages on the Internet or an intranet that can be easily edited by the public or a select group of registered visitors. Wikis are examples of collaboration. See “Wikipedia,” the most famous example of a wiki, below.
A wiki is run using wikis software, otherwise known as a wikis engine. The engine is a type of content management system, but it differs from most other such systems, including blog software, in that the content is created without any defined owner or leader, and wikis have little inherent structure, allowing structure to emerge according to the needs of the users. There are dozens of different of the engines in use, both standalone and part of other software, such as bug tracking systems. Some engines are open source, whereas others are proprietary. Some permit control over different functions (levels of access); for example, editing rights may permit changing, adding, or removing material. Others may permit access without enforcing access control. Other rules may be imposed to organize content.
It enables communities of editors and contributors to write documents collaboratively. All that people require to contribute is a computer, Internet access, a web browser, and a basic understanding of a simple markup language (e.g., HTML). A single page in a wikis website is referred to as a “wiki page”, while the entire collection of pages, which are usually well-interconnected by hyperlinks, is “the wikis”. A wiki is essentially a database for creating, browsing, and searching through information. It allows non-linear, evolving, complex, and networked text, while also allowing for editor argument, debate, and interaction regarding the content and formatting. A defining characteristic of wikis technology is the ease with which pages can be created and updated. Generally, there is no review by a moderator or gatekeeper before modifications are accepted and thus lead to changes on the website. Many are open to alteration by the general public without requiring registration of user accounts. Many edits can be made in real-time and appear almost instantly online. However, this feature facilitates abuse of the system. Private servers require user authentication to edit pages, and sometimes even to read them.
