What is a web browser?
A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources. A web browser can also be defined as an application software or program designed to enable users to access, retrieve and view documents and other resources on the Internet.
A browser is the program you use to view the internet with. The most popular (shudder) is Internet explorer, but others include Firefox, which I love, as well as Netscape, Opera, Mozilla, and more.
