Kilobyte (KB) =

A kilobyte (KB) is defined as 1,000 bytes in the context of digital storage. This measurement is based on the International System of Units (SI), where the prefix "kilo" represents 1,000. In computing, this standard is widely accepted for measuring file sizes and data storage capacity.

While in some contexts, particularly those referring to binary values, a kilobyte might be represented as 1,024 bytes (2^10), the answer provided aligns with the SI definition used in most digital communications. Understanding the size of a kilobyte is fundamental in fields such as multimedia design, where file sizes significantly impact performance, storage requirements, and data transfer speeds.
