Explain how binary number can give a signal or convert into a digital signal?

The binary number consists of either 0 or 1, in simple words number 1 represents the ON state, and number 0 represents the OFF state. These binary numbers can combine billion of machines into one machine or circuit and operate those machines by performing arithmetic calculations and sorting operations.
