Binary number is a numeral system (base-2 number system). This numeral system only includes two numbers: 0 and 1. For every 10 numbers in the decimal system that we use for calculation, we move it to next column. However, in the binary system, the number is moved to the next column for every 2 numbers. This numeral system started from about the 5th-2nd century BC, founded by an Indian scholar, Pingala. Binary numbers is a great foundation for Information Technology because computers can only understand two states: on and off (the state of electricity). That is why people developed a way to use the binary numeral system in the computer - 1 representing on and 0 representing off. This number (1 or 0 in binary number) equals to one bit.
