Why computers use binary

Comparison of 1-bit, 2-bit, and 3-bit binary patterns shown as switches, with 2, 4, and 8 possible states and notes that each extra bit doubles the patterns

Computers are electronic machines, so inside their circuits it is easiest to distinguish between two reliable conditions such as off/on or low/high voltage. That is why computers use binary, a system with just two digits: 0 and 1.
