An image has a resolution of 100 X 200 pixels and has a 16 bit colour depth (i.e. 16 bits used per pixel to represent a colour), what will the minimum memory requirements be for this image? Hint 1 byte=8 bits!!
40,000 bytes
30,000 bytes
40 bytes
400 bytes
An image has a resolution of 15 X 15 pixels. How many bytes is required for the whole image if the colour of each pixel was represented by 32 bits?

If 32 bits are used to represent the colour of one pixel and so 8 bits are used for Green, 8 bits for Red and 8 bits for Blue, then what are the remaining 8 bits used for?
They are ignored or used for providing transparency.
Used of determining the size of a pixel.
The remaining 8 bits are divided over the 3 parts of the colour (R,G and B).
