kilobajt

Kilobajt is a unit of digital information storage, commonly used in computing and telecommunications. It is defined as 1,024 bytes, which is 2 raised to the power of 10 (2^10). This unit is part of the International System of Quantities (ISQ) and is used to measure the capacity of digital storage devices, such as hard drives, USB drives, and memory cards. The kilobajt is also used to measure the size of files and data transfers, such as downloads and uploads. It is abbreviated as "KB" or "Kb" (lowercase "b" is used to distinguish it from the kilobit, which is a unit of data transfer rate). The kilobajt is part of the binary prefixes used in computing, which are based on powers of 2, rather than the decimal prefixes used in the metric system, which are based on powers of 10. The kilobajt is also used in the context of data compression, where it is used to measure the amount of data that can be compressed into a smaller file.
