Since the beginning of the digital computer, and even before this (when computers were mechanical), computers have always used "ones" and "zeros" for every calculation and operation.

*The processor and circuitry operate using electrical pulses.  A pulse is a "one" while a pause (no additional energy sent) is a "zero."   

*The processor and circuitry operate using electrical pulses.  A pulse is a "one" while a pause (no additional energy sent) is a "zero."   

*The [[Random-access memory|RAM]] switches are held in one position ("one") or released to the other ("zero")

*The [[Random-access memory|RAM]] memory bits are represented by charges ("one") or the absence of a charge ("zero")

*Magnetic disks are magnetized to positive or negative, which represent "zero" and "one"

*Magnetic disks are magnetized to positive or negative, which represent "zero" and "one"

*Optical disks have their foil melted by laser to show "zero" vs. "one"
