About these units
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.
Byte (B)
A byte consists of 8 bits, forming the standard grouping used in computing for representing characters, numbers, and machine instructions. This 8-bit size became dominant due to hardware design choices in early microprocessors, especially the IBM System/360 architecture. Bytes allow computers to represent values from 0 to 255, enabling ASCII encoding, color values, file metadata, and vast amounts of structured data. The byte is the basis for nearly all storage units—kilobytes, megabytes, gigabytes—and remains the fundamental digital "counting unit" for memory, disk space, and network transfers.
