How is 1 kilobyte commonly represented?

1 kilobyte is commonly represented as KB, which stands for kilobyte. In digital data measurement, the prefix "kilo" indicates a factor of 1,000 (in the context of decimal-based measurements) or 1,024 (in binary-based measurements) depending on the context in which it is used. The use of "KB" is standard in computing and data size discussions, making it a universally recognizable abbreviation in related fields.

The representation "Kib" refers to a kibibyte, which is defined as 1,024 bytes and follows the binary measurement system, but it is less commonly used than KB. The other options "GB" and "MB" represent gigabytes and megabytes, respectively, which are larger measurements of data and not applicable to the definition of a kilobyte. Hence, "KB" is the accurate and most recognized abbreviation for 1 kilobyte.
