Megabyte (MB)
The megabyte, symbolized as MB, is equal to 1,000,000 bytes in the decimal (SI) system, although in computing, it is often regarded as 1,048,576 bytes (1,024 KB). The term emerged in the 1960s as computers and storage capacity increased, making kilobytes insufficient for describing larger files. Megabytes are used for text, images, and small software applications, providing a human-readable scale for digital data capacity while bridging metric and binary conventions.
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.
