The difference between Analog and Digital.

The movement of electrons is called current. Current flows through wires, resistors and other devices designed to transmit electricity. This process is seen everyday in this new modern age. When referring to analog and digital you are referring to quantity or how much current is flowing through a wire or circuit. Analog refers to quantity while digital has a set amount. A good example would be turning up the volume on your radio, that is an analog signal because you are adjusting the quantity of the sound wave flowing to your speakers. Then you have the digital signal which has a set quantity. Think of 1 and 0 or on and off. You allow one unit of electrons to flow to turn on the light. Then you allow zero units of electrons to flow to turn the light off. This is the difference between analog and digital.
