What is the smallest unit of data used in computer processing?

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

Answer: (A)

Bits are the fundamental building blocks of digital information. A bit is a single binary digit that can be either 0 or 1, and it represents the most basic unit of data that a computer can process. All larger data items and instructions are built by combining bits into bigger units, such as a nibble (4 bits) or a byte (8 bits). While bytes and bigger groups are common for storing and handling data, the actual processing at the hardware level starts with individual bits. A zettabyte, by contrast, is a measure of data size, not a unit of processing.
