A '''bit''' is a single [[binary]] character. it is either a zero or a one. This is because data is stored in a "yes/no" format. On a magnetic drive, a point it magnetized as north or south. If it is recorded as north, this means 0, if South, then 1. In all other cases, a pulse or change is a one. A lack of signal or change means a zero. Optical drives have the foil backing melted in points to make these ones--gaps are zeros. Flash memory uses physical switches, which are set to "yes" or "no" (one or zero) by electric impulses. As a computer works and "thinks," it sends pulses through it's various systems for ones, and pauses for zeros. <ref>https://web.stanford.edu/class/cs101/bits-bytes.html</ref> | A '''bit''' is a single [[binary]] character. it is either a zero or a one.
