wiki

Imagine a shared online notebook that people can build together: that is essentially what a wiki is. The name comes from the Hawaiian word for "quick," which fits the idea of creating and updating pages easily. While Wikipedia is the most famous example, this kind of site is also used for many other things, like documenting software projects, building company knowledge bases, or sharing information within a group.

Think of it like a community garden where many people help things grow together. You might read one before writing a paper, or your team might use one to keep track of project details. The main idea is simple: people can add, edit, and organize information in one shared place.

A wiki is a website that lets people create, edit, and organize content together, usually right in a web browser. Unlike a more fixed website, this kind of site is built for ongoing changes by its users. Some are open to the public, while others are private and limited to a team, class, or company. In both cases, the goal is the same: to make it easy for people to build and update a shared body of information.

The term "wiki" was introduced by programmer Ward Cunningham in 1995, when he created the first wiki software, called WikiWikiWeb. He wanted a simple way for people to share and connect ideas. Today, these sites appear in many forms. Wikipedia is the best-known example: a huge multilingual encyclopedia built by volunteers. But this type of site is also common in workplaces for internal documentation, in education for group projects, and in online communities that collect and update useful information.

The strength of a wiki comes from collaboration. Because many people can contribute, information can grow quickly and stay up to date. At the same time, open editing can sometimes lead to mistakes, so many such sites use tools like moderation, page history, and access controls to maintain quality. Whether you are researching a topic, working with a team, or sharing practical knowledge, a wiki gives people a flexible way to build knowledge together.
