About these units
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.
Kilobit (kb)
A kilobit represents 1,000 bits (decimal), commonly used in telecommunications and networking. Unlike computer storage, networking units generally favor decimal prefixes, making kilobits distinct from kibibits (1024-bit units). Kilobits are often used to express low-bandwidth data rates—such as early dial-up Internet speeds (e.g., 56 kbps), small sensor networks, or radio telemetry. Though kilobits appear small today, many communication systems still operate efficiently at kilobit speeds, especially low-power IoT devices designed for long battery life and minimal bandwidth usage.
