Web Browser.

Web browser as a computer program used for accessing sites or information on a network (as the World Wide Web).

The browser application retrieves or fetches code, usually written in HTML (HyperText Markup Language) and/or another language, from a web server, interprets this code, and renders (displays) it as a web page for you to view. In the majority of cases, user interaction is needed to tell the browser what web site or specific web page he or she would like to view. One way this is done is via the browser's address bar.

The web address, or URL (Uniform Resource Locator), that you type into the browser's address bar tells the browser where to obtain a page or pages from.
