Binary Numerals

/ˈbaɪ.nɛr ˈnjuː.mə.rəlz/

noun — “the number system that thinks in ones and zeros so your computer doesn’t have to.”

Binary Numerals are a numeric system that uses only two digits—0 and 1—to represent all numbers. This base-2 system is the foundation of modern digital computing because electronic circuits naturally have two states: off and on. Every file, program, or computation inside a computer ultimately reduces to a long sequence of binary digits, making this system invisible yet absolutely essential in the modern world.
