About these units
Megabyte (MB)
A megabyte is traditionally 1,048,576 bytes (2²⁰), though storage manufacturers sometimes use the decimal version of 1,000,000 bytes. Throughout the 1980s and 1990s, megabytes represented substantial storage: early PCs had 256 kB or 512 kB of RAM, and hard drives with 10–40 MB were considered spacious. Software developers worked within tight memory budgets, optimizing every byte. Megabytes remain relevant today for file sizes such as images, audio files, small binaries, and executable programs. They mark a transitional era when computing moved from kilobytes to the far larger storage capacities we now expect.
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.
