About these units
DVD (1 layer, 2 side) (DVD (1L, 2S))
A single-layer, double-sided DVD offers 9.4 GB, with 4.7 GB per side, requiring the user to physically flip the disc. Double-sided DVDs were ideal in early DVD-era box sets and archival applications, but their inconvenience—no label side, no artwork, and manual flipping—limited consumer adoption. They represent a transitional form of optical media designed to increase capacity before dual-layer technologies became mainstream.
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.
