Role of Web Browser & Web Servers


web browser

A Web browser is a program that displays Web pages and other documents on the Web. Unfortunately, different browsers may interpret the HTML of Web pages somewhat differently, and thus, when you create Web pages remember that they may appear different when viewed in various browsers. The University supports the browsers illustrated below, which can be downloaded free from the company’s Web site.

A visitor can customize many display features of a browser, including:

background color


font size

text and link colors, and

whether or not to download images.


How Browsers Display Web pages

When a Web page is opened in a browser, the browser reads and interprets the HTML file and formats the Web page for display. If there are references to external files, such as images or multimedia, these files are downloaded from the server and displayed in the browser window. It is important to note that HTML files are text files that only contain references to the external files – you do not “embed” these files into the Web page

Web Server

Web servers are computers that deliver (serves up) Web pages. Every Web server has an IP address and possibly a domain name. For example, if you enter the URL in your browser, this sends a request to the Web server whose domain name The server then fetches the page named index.html and sends it to your browser.


Any computer can be turned into a Web server by installing server software and connecting the machine to the Internet. There are many Web server software applications, including public domain software from NCSA and Apache, and commercial packages from Microsoft, Netscape and others.
