About these units
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.
Terabyte (10^12 bytes) (TB (10^12))
A decimal terabyte equals 1 trillion bytes, a unit that defines modern large-capacity storage devices—from consumer HDDs to enterprise backup systems. The distinction between binary (1.099 trillion bytes) and decimal terabytes becomes especially noticeable at this scale. Disk manufacturers universally use decimal TB, while many file systems report binary values unless specifically configured otherwise. Terabytes represent massive datasets, enabling high-resolution video libraries, large backups, and entire scientific databases.
