Binary numbers are a number system that only use two digits: 0 and 1. It differs from the decimal number system that uses ten digits from 0 to 9.
Binary numbers are fundamental in digital electronics and computer programming, as computers use an electric current to represent information as either 0 or 1. This basic building block of the binary number system enables computers to process and store data (CPU, RAM, SSD…)
But it’s not just computers that use binary numbers, the internet, monitors and sensors also use them.
