How many bits are in a nibble?

• A. 8
• B. 4
• C. 2
• D. 16

Answer: (B)

A nibble is four bits. It’s half of a byte (since a byte is eight bits), and this half-size idea is why each hexadecimal digit represents four bits. So the nibble holds four distinct values, from 0000 to 1111. The other options don’t fit because eight bits make a full byte, two bits is smaller than a nibble, and sixteen bits equal two bytes.
