About these units
Kilobyte (kB)
A kilobyte traditionally represents 1,024 bytes (2¹⁰), reflecting binary-based memory design. Historically, operating systems, RAM modules, and floppy disks all used the binary kilobyte because memory addressing naturally aligned with powers of two. Kilobytes were once considered large: early computer programs and operating systems were measured in just a few kB. The first text-based adventure games fit entirely within 32 kB. Although kilobytes seem tiny today, they remain important for low-level embedded systems, boot loaders, configuration memory, and microcontrollers. The kilobyte is a reminder of computing's early constraints and the precision of binary address spaces.
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.
