Why computers think in only two numbers

In short: Every piece of data on your device, from photos to complex code, is distilled into a sequence of two digits. This video explains the fundamental logic of the binary system and how it serves as the bedrock of modern computing.

The binary system functions by using digits that represent powers of 2. Unlike the decimal system we use in daily life, which relies on ten digits, computers utilize a system where each position in a sequence represents a specific power of 2.

At the most basic level, computers store all information using one bit for each digit. This binary foundation allows hardware to process complex instructions by interpreting sequences of these simple units.
