What term describes the binary numbering system?

The binary numbering system is referred to as Base 2 because it uses only two symbols to represent all values: 0 and 1. In this system, each digit (or bit) represents a power of 2, which is fundamental to digital electronics and computing. Every increase in position to the left in a binary number corresponds to an increasing power of 2, just as each position in the decimal system corresponds to an increasing power of 10. This unique property of binary makes it suitable for digital circuits, which utilize two states (on and off) to perform operations and store data.

The other numbering systems mentioned, such as Base 8 (octal), Base 10 (decimal), and Base 16 (hexadecimal), correspond to different sets of symbols and bases. Base 8 uses digits 0-7, Base 10 uses digits 0-9, and Base 16 uses digits 0-9 and letters A-F to represent values. Each of these systems has its own special applications and contexts, but they do not apply to the binary system itself. Therefore, the correct designation for the binary numbering system is indeed Base 2.
