An electronic page is a term to encompass the grouping of content between basic breaking points in documents that originate or remain as visual electronic documents. This is a software file and recording format term in contrast to electronic paper, a hardware display technology. Electronic pages may be a standard sized based on the document settings of a word processor file, desktop publishing application file, or presentation software file. Electronic pages may also be dynamic in size or content such as in the case of HTML pages. When end user interactivity is part of the user experience design of an electronic page, it is better known as a graphical user interface (GUI). The number and size of electronic pages in a document are limited by the amount of computer memory, not by the display devices or amount of paper. Most electronic pages are for either display (screen output) on a computer monitor or handheld device, or output to a printing device. PDF and e-book pages are designed to do both. Most applications will print electronic pages without the need for a screen capture. However, not all software supports WYSIWYG printing of pages. Pages exclusively for screen output are more commonly known as screens, windows, interfaces, scenes, or cards. In the case of presentation software, electronic pages are known as slides.
