"MiB" stands for "Mebibyte," a unit of digital information storage. It is equal to 1,048,576 bytes, which is 2^20 bytes. The term is part of the binary system used in computing, where data is often measured in powers of two. Mebibytes are commonly used to describe file sizes and memory capacities in computer systems. The use of MiB helps avoid confusion with the similar term "MB," which stands for "Megabyte" and is equal to 1,000,000 bytes. This distinction is important in fields like computer science and data storage, where precise measurements are crucial for performance and compatibility.
