How binary works?

 

Binary is a number system that uses only two digits: 0 and 1, and it forms the foundation of all modern computing. Unlike the decimal system, which uses ten digits (0–9), binary is simpler and perfectly suited for electronic devices. Computers are built from millions or even billions of microscopic switches called transistors, and each transistor can be in one of two states: off (0) or on (1). Because of this, binary becomes the ideal language for computers to store and process information. A single binary digit is called a bit, and combinations of bits can represent much more complex data. For example, eight bits form a byte, which can represent values from 0 to 255—enough to encode letters, colors, and small pieces of data. Larger groups of bits can express huge numbers, detailed images, or even entire programs. When you type, click, or watch a video, your computer is constantly translating everything into long streams of 0s and 1s, performing calculations at incredible speed to make it all work.
