The word associated with practical scenarios where computer number systems are used is digital. Digital systems, including computers, rely on number systems, most prominently the binary number system (base-2), to represent and process data. Other number systems like hexadecimal (base-16) and octal (base-8) are also used in specific contexts within computing. Here's why "digital" is the best fit:Digital vs. Analog:Computers are digital devices, meaning they process information represented by discrete (separate) values, typically using binary code. Binary as the Foundation:The binary system, with its two digits (0 and 1), is the fundamental language of computers, enabling them to perform calculations, store data, and execute instructions. Other Number Systems:While binary is core, other systems like hexadecimal are used for representing memory addresses, and octal for encoding data, especially in older systems.
