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.
CD (80 minute) (CD (80 min))
The 80-minute CD expanded storage to 700 MB, offering a modest but meaningful increase over the 74-minute version. This capacity became the industry standard for audio production, software, and media distribution. The slightly denser data-spacing required careful calibration but proved reliable for most computer and consumer hardware. For many users, CD-R and CD-RW discs became a primary means of personal backups, music burning, and long-term storage before USB drives became widespread.
