What is the base-16 number system that includes digits 0-9 and letters A-F?

The base-16 number system is known as the Hexadecimal System. In this system, numbers are represented using 16 unique symbols: the digits 0 through 9 represent values zero to nine, while the letters A through F represent values ten to fifteen. This system is widely used in computer science and programming because it can compactly represent large binary numbers, making it easier to read and write. For example, the binary number 1111 1111 can be succinctly written as FF in hexadecimal.

The Hexadecimal System is valuable in various applications, such as color coding in web design (where colors are represented in hexadecimal format) and memory addresses in computer architecture. Its combination of numerical and alphabetic characters allows for a broader range of values to be represented with fewer digits compared to the decimal or binary systems.

The other options refer to different concepts:

• Categorical Data involves classifications or categories rather than numerical values.

• The Decimal System is base-10, utilizing the digits 0-9.

• The Binary System is base-2, using only two digits: 0 and 1.

Thus, the Hexadecimal System is specifically tailored for scenarios requiring a base-16 representation, making it the accurate choice for
