How many bytes constitute one kilobyte?

• A. 512 bytes
• B. 1,024 bytes
• C. 2,048 bytes
• D. 1,000 bytes

Answer: (B)

A kilobyte is defined as 1,024 bytes. This measurement is based on the binary system, which is used in computing and digital communications. In binary, the base unit is 2, and thus, the kilobyte is calculated as 2 raised to the power of 10 (2^10), equating to 1,024. This understanding is crucial for IT professionals since it directly impacts data storage, file sizes, and memory calculations. While there are other measurements for kilobytes, such as the metric system indicating 1,000 bytes in certain contexts (as used in some commercial storage devices), the standard in computing and data structuring is 1,024 bytes. Understanding this distinction helps professionals accurately interpret size and capacity in various computing environments.
