What is the name for the smallest amount of digital storage?

The smallest amount of digital storage is referred to as a bit. A bit is a binary digit, which can have a value of either 0 or 1, and represents the most basic data unit in computing and digital communications.

In the context of data storage, bits are the building blocks for more complex data structures. For example, a byte, which is composed of 8 bits, is the most common unit for measuring data storage. Other terms like nibble and word refer to larger groupings of bits; a nibble consists of 4 bits, and a word can vary in size (typically 16, 32, or 64 bits) depending on the computer architecture. Thus, the bit, as the smallest unit, serves as the foundation upon which all other digital storage measurements are built.
