Radix

Radix, in the context of computer science, refers to the base of a number system. For example, the familiar decimal system is base 10, using digits 0-9, while binary is base 2, using 0 and 1. Radix determines how numbers are represented and understood by computers. Radix sort is a specific algorithm that sorts numbers by processing each digit from the least significant to the most significant, which makes it efficient for large datasets with uniform digit lengths. Essentially, radix provides a foundation for translating and organizing numbers in different numeral systems or sorting techniques.
