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.
Floppy Disk (5.25", HD) (floppy (5.25" HD))
The 5.25-inch HD floppy stored 1.2 MB and represented the final evolution of the large-format floppy. HD versions were common in late-1980s IBM business systems and were used to distribute larger software packages and operating systems. However, the rise of the more compact and durable 3.5" floppy soon overshadowed the HD 5.25" format. Their rapid decline highlights how the industry moved toward miniaturization and higher reliability in portable storage.
