This document discusses the differences between web browsers and web servers. A web browser is software that retrieves and displays web pages and allows users to navigate between them. A web server stores web pages and other content and delivers it to users in response to their requests via HTTP. Some popular web browsers mentioned are Internet Explorer, Google Chrome, Mozilla Firefox, Safari, Opera and Lynx. Popular web servers include Apache, Microsoft, Nginx and Google. The key difference is that browsers view content while servers store and deliver content to browsers.
