What is a switch?
A switch is a device for changing the course or flow of a circuit. The switch is referred to as a "gate" when abstracted to mathematical form.

What does analog mean?
A continuously varying signal. For example, if an analog signal's range is from 0V to 5V, the signal can assume any voltage within that range such as 1.2, 2.4, or 4.7V. Microprocessors and microcontrollers usually cannot process analog signals directly and require conversion by an A/D converter before they can process the signal.
