What is the value of a kilobyte in bytes?

A kilobyte is defined as 1024 bytes. This specific value comes from the binary system that underpins computing. In binary, data is represented in powers of two, and 1024 is equivalent to (2^{10}). Therefore, in the context of data measurement, one kilobyte consists of (2^{10}) bytes, making it 1024 bytes.

This definition is important for understanding data storage and memory sizes in computers, as it establishes a consistent method for measuring smaller sections of digital information. When dealing with larger data values, this same principle is extended, leading to terms like megabytes (1,024 kilobytes) and gigabytes (1,024 megabytes), all rooted in the binary system.

In contrast, the other options provided do not correspond to the standard definition of a kilobyte in the context of binary measurement. They represent byte values that do not align with how computer memory and data units are typically understood.
