A bit is short for binary digit, let’s break it down. The binary number is made up from bits. Each bit a composed value of two things, 1 or 0, as in false or true, off or on, etc. A bit is the smallest unit of data in a computer.
Bits are the most basic unit of information that can be stored on a computer. A byte is made from eight bits. All information is larger than a bit, even a single character. So, in terms of measuring a file, a byte would be the smallest unit of measurement.
