About these units
Kilobyte (10^3 bytes) (kB (10^3))
A decimal kilobyte equals 1,000 bytes, reflecting the SI prefix kilo = 10³. Storage device manufacturers standardize on this definition because it scales cleanly and simplifies marketing and specification. This creates a mismatch with binary kilobytes (1,024 bytes) historically used in RAM and file systems. As storage capacities grew, this discrepancy became increasingly noticeable, leading standards bodies to promote explicit binary prefixes (KiB, MiB) for clarity. Despite these efforts, decimal kilobytes remain dominant in contexts such as hard drives, flash memory packaging, and communication standards.
DVD (2 layer, 1 side) (DVD (2L, 1S))
A dual-layer, single-sided DVD stores 8.5 GB using a semi-transparent layer that allows the laser to focus at two depths. This innovation enabled longer movies, higher-quality video, and special editions packed with supplemental content. Dual-layer DVDs became standard for commercial video distribution and professional data storage. Although burning DL DVDs at home was initially slow and expensive, they played a crucial role during the transition to higher-capacity optical storage.
