About these units
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.
Terabyte (TB)
A terabyte equals 1,099,511,627,776 bytes (2⁴⁰) in binary or 1 trillion bytes in decimal. Terabytes are associated with large-scale data storage: cloud drives, archival systems, scientific datasets, game installations, and high-definition video libraries. Modern personal computers often include terabyte-level drives, and enterprise systems may contain thousands of terabytes. The TB marks the boundary where storage becomes "big data," enabling machine learning training sets, genomic databases, and detailed satellite imagery archives. At this scale, efficient data management, compression, and redundancy become critical challenges.
