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", DD) (floppy (3.5" DD))
The 3.5-inch Double Density (DD) floppy disk typically held 720 KB of data and represented the evolution from earlier, more fragile 5.25-inch formats. Encased in a rigid plastic shell, 3.5" floppies provided improved durability, portability, and reliability. DD floppies became widely used in the late 1980s, particularly on early Macintosh and IBM-compatible computers. They were ideal for document storage, small software programs, and system utilities. Their limited capacity symbolized the constraints of early personal computing, forcing developers to design highly compact code and carefully manage file size. Despite their modest storage, DD floppies played a crucial role in early software distribution and data portability.
