Header and footer are often used to display additional information about a document, such as time, company name, file name or author name, etc.
For example, if you work for a company, you can add important information like the company name that you want readers to remember and familiarize with in the header and footer of the document for promotion and publicity. Or if you are a student, you can insert your name or document title in the header and footer of your document so that viewers can easily find your information at any time.
