1.  Define Aspect Ratio

~ Aspect ratio is an indicator of the proportional relationship of the width to the height of the screen and is depicted with the expression x:y, where x equals the number of units wide and y equals the number of units high.While the physical size of a display screen can vary, the aspect ratio remains constant

2.  List the aspect ratios for the following formats:

• 10" tablet (9.7" display)
• 4:3
• Smartphone (4.7" display)
• 16:9
• Leaderboard Ad
• 728:90
• HDTV 16:9
• 16:9

3.  Explain the difference between Interlaced & Progressive scanning.  Embed an image(s) that illustrate each. 

~ Interlace scanning is used to minimize bandwidth use and flickering where progressive scanning is consecutively scanning lines of the picture from top to bottom, just as you type on a typerwriter.
