Which base number system is also known as decimal?

The base number system known as decimal is referred to as denary. The denary number system uses base 10, which means it is composed of ten digits ranging from 0 to 9. This is the standard counting system used in most daily contexts, such as in mathematics, commerce, and in everyday life.

The other systems mentioned, such as binary, octal, and hexadecimal, are based on different bases, making them distinct from the denary system. Binary, for example, is base 2 and uses only the digits 0 and 1. Octal is base 8 and includes the digits from 0 to 7. Hexadecimal is base 16, utilizing the digits from 0 to 9 and the letters A to F to represent values. Understanding these distinctions is crucial in computer science, where different base systems are used for various applications, such as programming and data representation.
