The base-10 number system is primarily known as the Decimal system. It uses ten symbols or digits (0 through 9) to create numbers, and it is the most widely used number system in everyday life for counting and performing arithmetic tasks. The Decimal system is effective for representing quantities and performing calculations in a manner that is intuitive for humans, as it aligns with our natural counting system based on ten fingers.

In contrast, the other systems mentioned have different bases: the Binary system operates on base-2 and uses only two digits (0 and 1), which is fundamental in computer science as it represents the on/off states of transistors. The Hexadecimal system, or base-16, extends this concept by using sixteen symbols (0-9 and A-F), enabling a more compact representation of binary data. Lastly, the Octal system, based on base-8, also has unique applications in computing but is less common than the Decimal system for day-to-day activities and calculations.
