Pagination is a design technique used in web applications to break large volumes of content into smaller, more navigable sections. It typically includes navigation features such as page numbers, 'Next' and 'Previous' buttons, the ability to directly enter a page number via a numeric textbox, and sometimes a page selector or options for adjusting the number of items displayed per page. By presenting content in smaller chunks, pagination enhances the user experience, making it easier to browse and find relevant information without overwhelming users with excessive content at once.
