A nibble has how many bits?

Explanation:
A nibble is four bits. A bit is the smallest binary unit that can be 0 or 1, and with four bits you can represent 2^4 = 16 different values, which matches the range of a single hexadecimal digit (0 through F). Since a byte is eight bits, a nibble is half a byte, which helps explain the naming. The other options correspond to different sizes: two bits cover 4 values, eight bits make a full byte, and sixteen bits make a larger unit like a word.
