Power used in binary positions – UGC NET Question

In binary, each digit position corresponds to a power of 2, reflecting the base of the system. The rightmost bit is 2^0, the next is 2^1, then 2^2 and so on. This structure allows binary to represent any integer using only the digits 0 and 1. Therefore, each position represents a power of 2.

Option A:
Option A suggests powers of 8, which would be correct in an octal system, not in binary. Octal uses base 8, whereas binary is strictly base 2.

Option B:
Option B indicates powers of 10, which define the decimal system. Decimal numbers are based on 10 distinct digits, unlike binary.

Option C:
Option C is correct because binary's base is 2 and all positional weights are powers of 2. This is fundamental to how digital systems interpret bit patterns.

Option D:
Option D, 16, is the base of the hexadecimal system where each position is a power of 16. That system uses digits and letters to represent values.
