What is the equivalent of one kilobyte in bytes?

One kilobyte is equivalent to 1024 bytes. This measurement is rooted in the binary system used by computers, where data is often calculated in powers of two. A kilobyte, as defined traditionally in computing, represents 2 raised to the 10th power (2^10), which equals 1024 bytes.

The other choices refer to other metrics or misinterpretations. For example, 1000 bytes is sometimes used in contexts outside strict computing definitions, particularly in marketing or storage device specifications, but technically, it does not reflect the precise value of a kilobyte according to binary standards. The other options specifying 1 million bytes and 100 bytes do not relate to the definition of a kilobyte at all. A million bytes is typically denoted as a megabyte, while 100 bytes is simply a smaller number of bytes altogether.
