Which of the following represents the number of bytes in one Kilobyte (KB)?

One Kilobyte (KB) is commonly represented as 1,000 bytes in the decimal system, which is widely used in various contexts such as storage devices and data transfer. This interpretation aligns with the International System of Units (SI), where the prefix "kilo-" signifies a factor of 1,000. In everyday usage, especially in marketing and specifications for storage media, 1 KB is typically rounded to this decimal figure, making it easier for users to understand the capacity of devices like hard drives and flash storage.

While in computing contexts, the binary interpretation of a Kilobyte is sometimes referred to as 1,024 bytes (since it is 2^10), the question specifically seeks the decimal representation. Thus, the figure of 1,000 bytes is the more correct answer in this instance. The other figures represent larger byte values: 1,000,000 is the number of bytes in a Megabyte (MB), 1,000,000,000 refers to a Gigabyte (GB), and 1,000,000,000,000 denotes a Terabyte (TB). Therefore, the choice indicating 1,000 bytes accurately reflects the conventional understanding of a Kilobyte.
