About these units
DVD (2 layer, 2 side) (DVD (2L, 2S))
The dual-layer, double-sided DVD provides the maximum DVD capacity: 17.1 GB. With two layers on each side, these discs offered exceptional storage for large software packages, high-definition video masters (before Blu-ray), and professional archival applications. However, they were rarely used in consumer markets due to cost, complexity, and the inconvenience of double-sided handling. They remain an interesting pinnacle of DVD engineering—pushing the medium to its physical limits.
Kilobyte (kB)
A kilobyte traditionally represents 1,024 bytes (2¹⁰), reflecting binary-based memory design. Historically, operating systems, RAM modules, and floppy disks all used the binary kilobyte because memory addressing naturally aligned with powers of two. Kilobytes were once considered large: early computer programs and operating systems were measured in just a few kB. The first text-based adventure games fit entirely within 32 kB. Although kilobytes seem tiny today, they remain important for low-level embedded systems, boot loaders, configuration memory, and microcontrollers. The kilobyte is a reminder of computing's early constraints and the precision of binary address spaces.
