What is the smallest unit of digital information?

The smallest unit of digital information is a bit. A bit, which stands for "binary digit," represents a single binary value of either 0 or 1. This fundamental building block of data is crucial in computing and telecommunications, as it serves as the basis for all digital data representation.

When bits are grouped together, they form larger units—like bytes, which are composed of 8 bits. Further divisions include kilobytes (1,024 bytes) and megabytes (1,024 kilobytes), making them significantly larger units of digital information. Understanding bits as the foundational unit of data is essential for grasping how digital systems encode, process, and transmit information.
