2. graphics calculating

   • e.g
     • 200 pixels x 200 pixels for black and white pictures
     • 200 pixels x 200 pixels x the amount of colour in binary
       • then divided into the smallest number you can get in unties
     • 6 inch by 2 inch picture
       • 10 pixels per box
       • (6X10)X(2X10)
         • 60 X 20
           • 1200
             • DIVIDED BY 8 TO GET BYTE
             • 150 BYTES
             • TO GET KILOBYTE DIVIDE BY 1024
