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

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

Answer: (B)

A bit is the smallest unit of data used in computer processing. It’s a binary digit that can hold one of two values, 0 or 1, and all data and instructions in a computer are ultimately represented as sequences of bits. Logical and arithmetic operations are performed by manipulating these bits according to Boolean rules. Larger groupings like a nibble (4 bits) or a byte (8 bits) are handy for representing information and for practical processing, but they are just convenient bundles of bits. A zettabyte is a huge unit of storage capacity, not a unit used for processing data.
