About these units
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.
Gigabyte (GB)
A gigabyte is 1,073,741,824 bytes (2³⁰) in binary notation, or 1,000,000,000 bytes in decimal form. Gigabytes serve as one of the most common units of modern computing: RAM capacities, smartphone storage, software downloads, and video file sizes frequently range from a few GB to dozens of gigabytes. The gigabyte era represented a massive shift in capability—allowing high-resolution multimedia, complex software, virtual machines, and databases to flourish. While once enormous, gigabytes are now considered routine, illustrating the exponential growth of digital storage.
