Wikipedia is a comprehensive, freely accessible online encyclopedia that anyone with an internet connection can edit and contribute to. It operates on a model of collaborative editing, where articles are written and updated by volunteers from around the world. The platform covers a vast range of topics and strives to present information in a neutral, verifiable manner, with content continuously reviewed and refined by its user community. Managed by the Wikimedia Foundation, Wikipedia's goal is to provide accurate and reliable information to the public, democratizing knowledge and making it universally accessible.
