what does an internet browser do
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

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
