Which unit is defined as eight bits?

• A. Nibble
• B. Word
• C. Byte
• D. Bit

Answer: (C)

Eight bits form a byte—the standard unit used to store a single character or a small amount of data. Each bit is a 0 or 1, so eight of them create 2^8 = 256 possible patterns, enough to represent characters, numbers, and other data. A nibble is four bits, which is half a byte, and a word is a larger unit that varies by architecture (often 2, 4, or 8 bytes). So the unit defined as eight bits is the byte.
