A browser is an application that provides a way to look at and interact with all the information on the World Wide Web. Technically, a web browser uses HTTP to make requests of web servers throughout the Internet on behalf of the browser user. In other words, a web browser is a software application that allows one to view pages on the World Wide Web.

The history of the web browser can be traced back to 1991, when a computer guru named Tim Berners-Lee invented the very first web browser. It premiered on February 26, 1991, and ran on NeXSTEP. It was called WorldWideWeb, but was later renamed Nexus in an effort to avoid confusion with the World Wide Web.

There are different web browsers that are available and in use today and they all come with a variety of features. Some of the available web browsers include Amaya, AOL Explorer, Arachne, Arlington Kiosk, Avant, Camino, Dillo, Elinks, Epiphany, Flock, Galeon, iCab, Internet Explorer, Internet Explorer for Mac, K-Meleon, KioWare, Konqueror, Links, Lynx, Maxthon, Mosaic, Mozilla, Mozilla Firefox, Netscape, OmniWeb, SeaMonkey, Safari, Opera and Off By One.

Web browsers also come with some features. Some common features that are included with web browsers are spell checkers, search engine toolbars, download managing, password managing, bookmark managing, as well as form managing. Accessibility features that may be included with many web browsers include page zooming, ad filtering, pop-up blocking, tabbed browsing, incremental finding, HTML access keys, voice controls, mouse gestures, spatial navigation, text to speech, and caret navigation.

A web browser is a powerful tool, and isn't just used for personal computers anymore; there are web browsers that can be used on mobile phones, handheld game systems, as well as pocket PC's.

Web browsers can also be personalized to an individuals needs by utilizing web browser accessories that are not included with the initial browser software.
