binary digits

Computer's counting symbols

Binary digits are the two numerals—0 and 1—used in the base-2 number system that underlies all digital computing.

Every piece of data a computer processes reduces to sequences of binary digits.

The term is usually contracted to bits: a 64-bit processor, bits per second.
