what is header and footer in ms word

In Microsoft Word, a header is a section of the document that appears in the top margin, while a footer is a section that appears in the bottom margin. They generally contain additional information such as page numbers, dates, an author's name, and footnotes, which can help keep longer documents organized and make them easier to read. Text entered in the header or footer will appear on each page of the document. You can add or change text for the header or footer, and Word has a variety of preset headers and footers you can use to enhance your document's design and layout. To insert a header or footer, you can go to the Insert tab and select Header or Footer, then choose from a list of standard headers or footers or create your own. To edit a header or footer that's already created, you can double-click on it. If you want to delete a header or footer, you can select Insert > Header (or Footer) > Remove Header (or Remove Footer)
