The smallest unit of measurement used for measuring data is a bit. A single bit can have a value of either 0 or 1. It may contain a binary value (such as On/Off or True/False), but nothing more. Therefore, a byte, or eight bits, is used as the fundamental unit of measurement for data. A byte can store 28 or 256 different values, which is sufficient to represent standard ASCII characters, such as letters, numbers and symbols.
Since most files contain thousands of bytes, file sizes are often measured in kilobytes. Larger files, such as images, videos, and audio files, contain millions of bytes and therefore are measured in megabytes. Modern storage devices can store thousands of these files, which is why storage capacity is typically measured in gigabytes or even terabytes. Larger units of measurement are usually reserved for measuring the sum of multiple storage devices or the capacity of large data storage networks.
Below is a list of all the standard units of measurement used for data storage, from the smallest to the largest.
