#Binance binary is a base-2 numeral system using only two digits, 0 and 1, to represent numbers and data. Each digit is called a bit, and combinations of bits form binary codes. This system is fundamental to computing, where "0" represents off or false, and "1" represents on or true, enabling computers to process information. Binary is used to represent text, numbers, images, and other data, making it the language of computers and digital devices.
