The correct choice signifies that a kilobyte is indeed the measurement equivalent to 1,000 bytes in digital file size. In computing, file sizes are often quantified using various units based on powers of two or ten. The kilobyte is defined as a unit of digital information that is commonly understood to be 1,000 bytes in the context of decimal-based measurements, particularly in terms of storage media and file sizes.

In practice, while some contexts might use the binary definition where a kilobyte is regarded as 1,024 bytes, the more widely adopted and simplified decimal definition in consumer technology refers to a kilobyte as 1,000 bytes. This distinction is crucial in understanding how file sizes are communicated, especially in the realms of data transfer and storage capacity where clarity around size can significantly impact usability and user experience.

Understanding these units—such as how a kilobyte relates to larger units like megabytes (1,000 kilobytes) and gigabytes (1,000 megabytes)—is essential in software and app design, as it impacts how data is stored, processed, and transferred.
