Which term best describes a binary digit?

• A. Pixel
• B. Array
• C. Bit
• D. Encryption

Answer: (C)

A bit is the smallest unit of data in computing, representing a choice between two values—0 or 1. This binary foundation is what all digital information is built from; many bits together form bytes and larger structures that store text, images, and programs. A pixel, on the other hand, is the smallest element of a digital image and requires multiple bits to encode color. An array is simply a collection of items stored together, not a single data unit. Encryption is a process that transforms information to hide its meaning, not a single digit. So the term that describes a binary digit is bit.
