What is the nature of binary code regarding representation of values?

Binary code is defined by its use of a two-symbol system, specifically zeros and ones. This dual nature is foundational to digital systems, as it aligns with the on/off states of electronic circuits. When we talk about binary code, we refer to its ability to represent all types of data—whether it be numbers, letters, or symbols—using combinations of these two digits.

In digital computing, every piece of data is ultimately converted to binary because computers operate on this binary level. For example, the letter 'A' in ASCII is represented as 01000001 in binary. Thus, what makes the correct answer valid is the recognition that binary code has the capacity to represent a vast array of values and data types through arranged sequences of zeros and ones.

The other answers don’t accurately reflect the characteristics of binary code. While numeric characters and special symbols are used in other coding systems, they do not describe binary itself, which is solely about zeroes and ones. Alphanumeric systems incorporate letters and numbers but do not form the base of binary representation, which is exclusively built on two symbols.
