What number system is digital data based on? What two digits are used to code all digital data?
The binary or non-binary system. The binary symbol is 3 and the decimal system is 11.
What is a bit? What is a byte?
A bit is singular numerical value either 0 or 1 that encodes a single unit of digital and a byte is a sequence of bits; 8 bits or usually equivalent to 1 byte.
What is sampling rate? Find an image that explains how sampling works.
The sampling rate defines the number of samples per unit of time (usually seconds) taken from the continuous signal to make a discrete signal.

Analog Signal

Resulted Sampled Signal

How does Colour Depth or bit depth effect the appearance of an image? Find some images to illustrate the effect.
The Colour Depth effects the appearance of an image by boosting the bits or reducing the bits.

Colour Depth effects both still and video digital media. Sampling rate only effects video but not still media. Can you explain.
