About these units
Quadruple-Word (quad-word)
A quadruple word (quad-word) is a grouping of four standard words. On a 64-bit system, this equals 256 bits, forming the basis of advanced operations such as wide integer arithmetic, extended SIMD instructions, cryptographic keys, and high-precision floating-point values. Modern CPUs support quad-word operations through SIMD extensions like AVX and AVX-512, allowing parallel processing of large blocks of data in scientific computing, video encoding, machine learning, and physics simulations. Quad-words illustrate how data grouping evolves with hardware capability: as processors grow more powerful, software increasingly relies on larger and more complex data units.
Gigabyte (10^9 bytes) (GB (10^9))
A decimal gigabyte is 1,000,000,000 bytes and is the standard unit for hard drive and SSD capacities. As storage technology scaled into the hundreds of gigabytes and then terabytes, the decimal definition became more practical, allowing consistent scaling across consumer and enterprise devices. However, operating systems often report capacities using binary units, causing user confusion (e.g., a "500 GB" drive showing only ~465 "GB"). This mismatch persists despite standardization efforts.
