2. Suppose a digital camera has a storage capacity of 256MB. How many photographs could be stored in the camera
if each consisted of 1024 pixels per row and 1024 pixels per column if each pixel required three bytes of storage?
3. Suppose a picture is represented on a display screen by a rectangular array containing 1024 columns and 768
