Data amounts is a term used to describe the size of digital information. BYTES are the smallest unit of digital information, and are typically used to measure the size of a file or data set. A byte is made up of 8 bits, and is usually represented by a number followed by the letter B. For example, 1KB (kilobyte) is equal to 1024 BYTES. Data amounts can also be measured in megabytes (MB), gigabytes (GB), and terabytes (TB).
