Base of a number system is also known as:
- Shift
- Count
- Value
- Radix
Correct answer: 4. Radix
Explanation: In the context of number systems, the base is referred to as the radix. The radix represents the number of unique digits (including zero) used to represent numbers in that system. For example:
- In the decimal system (base 10), the radix is 10 because it uses ten digits (0 through 9).
- In the binary system (base 2), the radix is 2 because it uses two digits (0 and 1).
- In the hexadecimal system (base 16), the radix is 16 because it uses sixteen digits (0 through 9 and A through F).
The base or radix is crucial in determining the value of a number and understanding its positional notation within the number system. It’s the foundation upon which the entire numbering system is built. So, “Radix” is the correct term for the base of a number system.
