Description : A friend told me that if I have a photo, for example, that they are basically just written numbers, is it true? I mean, for example, if I'm going to copy a photo to a CD, I'm just going to copy only the numbers and not the picture. It is so?
Last Answer : My friend is right. The computer works in binary system I = On 0 = Off. I'll simplify it now See a picture printed by a dot matrix printer or a newspaper page. Note that all characters are made up of dots ... (1) and empty (0) points - pulses - is written in the memory image. the base unit is 1bit.
