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.
CD (74 minute) (CD (74 min))
A 74-minute CD typically holds 650 MB of digital data. Originally designed for audio playback, CDs later became a major format for software distribution, backups, and digital media. The 74-minute length was chosen to accommodate Beethoven's Ninth Symphony on a single disc—a blend of engineering, commerce, and cultural symbolism. As CDs pivoted to data storage (CD-ROM), their precise reflectivity patterns and error-correction codes allowed reliable long-term archival. These discs became essential for installing software, distributing games, and storing personal files throughout the 1990s and early 2000s.
