A.

The BEST statement that describes binary is A. "A notational system used to represent an on or off state."

Binary is a numerical system that uses two digits or values, typically 0 and 1, to represent information. It is also referred to as the base-2 system. Computers use binary to store and process data, as it is easy to represent the two states of an electrical circuit as either 0 or 1.

In binary notation, each digit represents a power of 2, and the position of the digit determines its weight. For example, the binary number 1011 represents the decimal value of (12^3)+(02^2)+(12^1)+(12^0) = 8 + 0 + 2 + 1 = 11.

Binary is not used to represent media access control or Internet protocol addressing, as these use different notational systems. Media access control uses hexadecimal notation, which represents numbers using 16 digits (0-9 and A-F), while Internet protocol addressing uses decimal notation, which represents numbers using 10 digits (0-9).

Finally, binary is not used to represent a storage unit of measurement, as this is typically done using decimal notation. Storage units such as bytes, kilobytes, and gigabytes are multiples of 10, not 2.
