Web Browser:
An Internet Browser is a computer program that allows you to view pages, images and multimedia available on the World Wide Web (WWW). The two most popular are Netscape Navigator and Microsoft Internet Explorer.
This is the software that allows a user to view HTML documents (In other words, surf the net). Examples of Web browsers include Netscape, Mosaic, Internet Explorer and Lynx.
A Web browser is your window to the Internet. The browser reads the HTML code in the Web document and translates the code into the final product. The page appears as the author intended it to, with text, graphics and hypertext jumps to other Web Pages.
