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", ED) (floppy (3.5" ED))
The 3.5-inch Extended Density (ED) floppy disk increased storage to 2.88 MB, nearly double the HD version. Despite the additional capacity, ED disks never achieved widespread use. They required compatible drives, were more expensive, and emerged during a period when optical and magnetic storage technologies were advancing rapidly. Their brief existence reflects an inflection point in storage history—where incremental magnetic improvements could no longer keep pace with the exponential growth in software size and consumer demand.
