What is the smallest unit of data in a computer?

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

Answer: (D)

Bits are the basic unit of data in computers; each bit can hold a value of 0 or 1, representing the simplest piece of information. All data—numbers, text, images—are ultimately stored and processed as long sequences of these bits. Larger data units are built from bits: a nibble is four bits, a byte is eight bits, and a word is a chunk defined by the machine’s architecture (often two, four, or eight bytes). Because you can’t split information into smaller pieces than a single bit, the bit is the smallest unit of data.
