A) 1,000 B) 1,024 ü C) 1,080 D) It depends on your computer’s operating system
The prefix “kilo” usually means one thousand: a kilogram is exactly 1,000 grams. For technical reasons, however, computer memories are organized around numbers that are powers of two (numbers that can be obtained by repeatedly multiplying two by itself). 1,024 is such a number (2 raised to the 10th power). The term “kilobyte” is merely a convenient approximation. Similarly, a megabyte is 1,048,576 (1024 times 1024) bytes, rather than exactly one million as the “mega” prefix would suggest.
