About these units
Gigabyte (GB)
A gigabyte is 1,073,741,824 bytes (2³⁰) in binary notation, or 1,000,000,000 bytes in decimal form. Gigabytes serve as one of the most common units of modern computing: RAM capacities, smartphone storage, software downloads, and video file sizes frequently range from a few GB to dozens of gigabytes. The gigabyte era represented a massive shift in capability—allowing high-resolution multimedia, complex software, virtual machines, and databases to flourish. While once enormous, gigabytes are now considered routine, illustrating the exponential growth of digital storage.
Megabyte (10^6 bytes) (MB (10^6))
A decimal megabyte equals 1,000,000 bytes, used widely for describing hard disk storage, file sizes, and digital media capacity. Manufacturers favor decimal prefixes because they produce cleaner, larger-sounding numbers compared to binary equivalents. For example, a "500 MB" device would be smaller in binary units. Consumers and engineers must interpret megabytes within context, distinguishing whether a manufacturer intends binary or decimal. Although decimal megabytes dominate mass-storage descriptions, binary megabytes remain common in system memory and software.
