Binary numeral system

The binary numeral system uses only two digits: 0 and 1. It’s the foundation of how computers process and store data. Instead of using ten digits like the decimal system, binary assigns each position a power of 2. For example, in binary, 101 translates to (1×4) + (0×2) + (1×1) = 5 in decimal. Computers interpret these binary digits as signals, with 0 representing off and 1 representing on. This simple system allows precise, efficient digital operations, making it essential for computing, data transmission, and digital technology.
