What is the purpose of a footer in a document?

The purpose of a footer in a document is to contain information such as the page number, date, and document name. This section is usually located at the bottom of each page and serves as a consistent reference point for readers. Including this information in the footer helps maintain clarity and organization throughout the document, allowing readers to easily keep track of where they are, especially in lengthy or multi-page documents. This structural element enhances the usability and professionalism of the document, making it easier for users to locate specific information and remember key details associated with the content.
