The Internet


 
The internet service provider sends your request to other servers on the internet and transmits the files to you.   The internet is a world-wide network of servers. Your request bounces around until it finds the requested server with the information.

 

 

 

 

 

The browser on your computer sends requests for html (Hypertext markup language) files to a remote server by using addresses called URL's (Uniform Resource Locators). The http command (Hypertext Transport Protocol) is the standard for sending the data across the web

When the file arrives the browser displays the text, graphics and sound.

  The web server holds the information requested in the form of html text, graphics, sound and video files and will send them to you upon request utilizing gateway scripts.
