A kilobyte is equal to approximately one ________ bytes.

• A. Hundred
• B. Thousand
• C. Million
• D. Ten Thousand

Answer: (B)

A kilobyte is a unit of data size in which the kilo- prefix means roughly a thousand. In computing, sizes are counted in bytes, and a kilobyte is commonly described as about one thousand bytes. In practice there are two common definitions: decimal kilobyte = 1000 bytes, and binary usage historically defined as 1024 bytes. Since 1024 is very close to 1000, the idea of “approximately” one thousand bytes fits best.

The other options are much farther away in scale: a hundred is too small, ten thousand is ten times larger, and a million is much larger still.
