How many bytes are in one kilobyte?

One kilobyte is defined as 1024 bytes in the context of computer science and digital storage. This measurement is part of the binary system used in computing, where data is processed in powers of 2. Since 1 kilobyte (KB) equals (2^{10}) bytes, performing the calculation results in 1024 bytes.

The distinction can sometimes be made when considering the decimal system, where one kilobyte might be interpreted as 1000 bytes, but in the context of memory addressing and file sizes in computing, 1024 bytes is the standard definition. This binary representation is pivotal for various computing functions, including memory allocation and data handling, where the binary progression aligns with how computer memory is structured.

Understanding this distinction helps clarify why the answer is 1024 bytes, as it is commonly adopted in the fields of computer science and information technology.
