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.
CD (80 minute) (CD (80 min))
The 80-minute CD expanded storage to 700 MB, offering a modest but meaningful increase over the 74-minute version. This capacity became the industry standard for audio production, software, and media distribution. The slightly denser data-spacing required careful calibration but proved reliable for most computer and consumer hardware. For many users, CD-R and CD-RW discs became a primary means of personal backups, music burning, and long-term storage before USB drives became widespread.
