A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web.
A Web Browser is a Tour Guide
If you wanted to visit a specific building in a new city, and were taking a tour, you could ask a tour guide to take you there. If the address is valid, he or she can point to the building on a map and look there for what you want.
Everything on the web lives in a specific building: a web server identified by an IP Address and DNS entry. When you ask to see a web page, the browser looks at the URL you are requesting and finds the web server corresponding to that request. It then asks for the specific web page in that building.clintandrewhall
