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 (3.5", HD) (floppy (3.5" HD))
The 3.5-inch High Density (HD) floppy stored 1.44 MB, becoming one of the most iconic storage formats of the 1990s. HD floppies were ubiquitous—used for school assignments, office documents, driver disks, BIOS updates, and even early game installations. Their capacity was sufficient for word processing files, spreadsheets, and modest multimedia content of the era. Although minuscule by modern standards, the HD floppy revolutionized everyday computing by offering a cheap, standardized, nearly universal storage medium. Its influence persisted until USB drives and CDs supplanted it in the early 2000s.
