In digital systems, what term describes the smallest unit of data that can be 0 or 1?

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

Answer: (C)

The fundamental idea is that data in digital systems is built from the smallest possible binary unit: the bit. A bit can have only two states, 0 or 1, and everything a computer stores or processes is ultimately represented as sequences of these bits. A nibble is just four bits together, used for convenience in certain representations like hexadecimal. A byte is eight bits, the common unit for representing a character or a small value. A word is a larger, architecture-dependent unit that the processor handles as its basic data path. Because a bit is the smallest unit that can hold a binary state, it is the correct answer.
