Kilobyte (KB)
The kilobyte, symbolized as KB, represents 1,000 bytes in the decimal system (SI), although in computing, it is commonly approximated as 1,024 bytes. The unit emerged in the 1960s as computer memory and storage expanded and was used for measuring small file sizes, such as text documents and early software. The kilobyte reflects the practical intersection of metric and binary measurements, which led to the introduction of binary-specific units, such as the kibibyte. Kilobytes are still used in some legacy systems and file specifications.
Tebibyte (TiB)
The tebibyte, symbol TiB, equals 1,099,511,627,776 bytes (1,024 GiB) and was introduced by the IEC in 1998. This binary unit provides precision for storage systems, servers, and cloud infrastructure, eliminating confusion between TB (decimal) and TiB (binary) in technical contexts. Tebibytes are essential for accurate reporting and planning in data centers, enterprise IT, and software development. Standardization supports consistency in global computing practices.
