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.
Terabyte (10^12 bytes) (TB (10^12))
A decimal terabyte equals 1 trillion bytes, a unit that defines modern large-capacity storage devices—from consumer HDDs to enterprise backup systems. The distinction between binary (1.099 trillion bytes) and decimal terabytes becomes especially noticeable at this scale. Disk manufacturers universally use decimal TB, while many file systems report binary values unless specifically configured otherwise. Terabytes represent massive datasets, enabling high-resolution video libraries, large backups, and entire scientific databases.
