1. An image is 800 by 500 pixels, and each pixel can be one of four colors. How much memory would it require?
500 * 800 = 400,000 pixels, 400,000 * 2 = 800,000 bits
2. An image is 800 by 500 pixels, and each pixel can be one of four colors. How much storage space would it require?
500 * 800 = 400,000 pixels, 400,000 * 2 = 800,000 bits
3. How many different colors could one represent using two, three and four bit codes?
A two-bit code gives 4 different colors. A three-bit code gives 8 different colors. A four-bit code gives 16 different colors.
4. When you add one bit to a code, what happens to the number of possible colors?
When you add a bit to the code the number of different colors doubles.
