So What Can Be Stored In Binary?
In binary we can store text, image, and sound using various different methods of binary storage.
How Would We Would Store Image?
My Method
We would store image by representing different pixels by different binary digits. For example a black pixel would be a 1 and a white pixel would be a 0.
Exam Style Answer
Split the image into a grid/pixels
Each square = 1 binary bit of information
Black = 1
White = 0
Encode groups of black and white together or whole rows
How Is Colour Image Encoded?
Colour image is encoded by RGB. These three colours (Red, Green and Blue) can make up any other colour. This would mean Red is FF0000 and Green would be 00FF00 and Blue would be 0000FF. So to make purple you would mix Red and Blue so purple would be FF00FF. So to encode the colour image each colour pixel would be different RGB value.

Colour uses RGB which is Red, Green and Blue
For Red it would be
FF0000
00FF00 would be Green
0000FF would be Blue
Black would be 000000
White would be FFFFFF

Sound is encoded by having sample points at different points in a grid. The computer will make up the sound in between the sample points because of how clever they are although will not be completely accurate. To stop this happening all you do is add more sample points so the computer does not have to fill in as many gaps so the sound will be more accurate. It is good to have a lot of sample points on curves because otherwise the computer will see it as a spike rather than a curve and the sound will not sound accurate.
