Binary Number System

What Does Binary Number System Mean?

The binary number system is a numbering system that represents numeric values using two unique digits (0 and 1). Mosting computing devices use binary numbering to represent electronic circuit voltage state, (i.e., on/off switch), which considers 0 voltage input as off and 1 input as on.

This is also known as the base-2 number system, or the binary numbering system.


Techopedia Explains Binary Number System

Microcontrollers only use binary logic in computing. Compare this to the decimal numbering system, which is comprised of 10 unique digits (0-9). For example, a user input of 345 (in decimals) is 101011001 in binary form.
