About these units
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.
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.
