Byte (B)
A byte, represented by the symbol B, is made up of 8 bits and serves as a standard unit for digital information. The idea of the byte was established in the 1950s when early computers needed a consistent way to group bits to encode characters like letters and numbers. As the fundamental element for organizing and storing digital data, bytes are used in everything from documents to multimedia files. Today, the byte is the universal reference point for measuring memory, storage capacities, and file sizes, forming the foundation for all larger digital units.
Mebibyte (MiB)
The mebibyte, symbol MiB, equals 1,048,576 bytes (1,024 KiB) and was introduced by the IEC in 1998 to eliminate ambiguity between MB (decimal) and MiB (binary). It is commonly used in operating systems, memory specifications, and technical documentation where exact binary measurement is required. Mebibytes provide clarity and consistency, especially in software development and systems engineering, ensuring accurate memory allocation, storage calculations, and file size reporting.
