Why do computers use Binary

The binary number system is at the heart of digital computing. Having two components, alternatives, or outcomes. The binary number system has 2 as its base, so values are expressed as combination of two digits, 0 and 1. These two digits can represent the logical values true and false as well as numerals, and they can be represented in an electronic device by the two states on and off, recognized as two voltage levels. Therefore, the binary number system is at the heart of digital computing.

Although ideal for computers, binary numbers are usually difficult for people to interpret because they are repetitive strings of 1s and 0s. To ease translation, programmers and others who habitually work with the computers internal processing abilities Computers translate information into binary numbers in a process called digital encoding. Every letter is replaced with its numerical position in the alphabet. Sounds are encoded as numbers measuring pitch and volume at each instant. Images are encoded as numbers representing the color and brightness of each portion. The computer can convert the numbers back into letters, sounds, or images. All computer instructions and data are converted into binary numbers.
