How many bits equal a nibble?

• A. One
• B. Two
• C. Four
• D. Eight

Answer: (C)

Four bits make up a nibble. This comes from how data is structured: a byte is eight bits, so a nibble is half a byte. Four bits also map to 16 values, which aligns with representing a single hexadecimal digit. So the number of bits in a nibble is four. The other options don’t fit because one bit is just a single binary digit, two bits form a smaller 2-bit group with no standard name, and eight bits is a full byte, not a nibble.
