Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.
