Web browser is a software application that retrieves, present and traverses information resources on the World Wide Web (www). Initially, it is only able to access the www but now enables information access offered by web servers and private networks or files in file systems. Moreover, it can be used to view the HTML-formatted documents.
The examples include Internet Explorer, Google Chromes and Mozilla Firefox.
