It is a form of media where data is stored in digital form.
Questions:

Digital media includes anything that is presented in an audio (sound) or video (visual) form that can be seen and heard by others. Examples of digital media can include music files such as mp3, Midi or WMA files, video feeds found on the Internet at popular video websites, and animated flash or graphic design files and images used to create interactive websites and games.Computers, Iphone, Ipod.

What is a bit? What is a byte?
The byte is a unit of digital information in computing and telecommunications. It is an ordered collection of bits, in which each bit denotes the binary value of 1 or 0.
What is “sampling rate”? Find an image that explains how sampling works
The sampling rate defines how many samples there are per second or per unit taken from a continous signal to make a discrete signal.This image shows an example of a sample rate. The first image is 8 samples per second and the second one is 16 samples per second.
How does Colour Depth (Color Depth) or bit depth effect the appearance of an image?
The higher the colour depth the most distict the image's colour will be. The number of bits a coloured picture has the more clearer the image will be. here are some images that will show the effect.
