  3. What does an Internet Browser do? • It goes to a computer at an address that you specify and retrieves a particular file of text • You provide the address, e.g.www.google.co.uk, and the filename is often assumed, e.g. index.html • The addressed computer is a Web Server • Displays the contents of this text file; this is a Web Page • Executes the embedded commands • Some common commands are: • Enhance the text, e.g. bold, italics • Display a picture • Give the user a place to select an alternative file to display, replacing the current one; this is a Hyperlink • Execute a Javascript program

  4. Browser Add-ons • These are small programs that you choose to install inside your browser (therefore making it bigger) • Similar to Apps on smartphones • They add useful automation to some of the interactive work you do with a browser, e.g. shopping • For example: • Fill in a form with your name & address • Check your spelling • Translate from a foreign language • Provide control over Javascript programs
