In IT, the term kilobyte (KB) is traditionally used to connote which of the following?

EXPLANATION

Because computers are binary (base 2) instead of decimal (base 10), 1KB would be 2 to the 10th bytes, or 1024.

In fact, the definition of KB (kilobytes) was changed in 1998 to match up with SI units, the current term for 1024 bytes is Kibibyte (https://en.wikipedia.org/wiki/Kibibyte). That said, most IT pros still prefer the traditional definition of KB as 1024 bytes, since it's the most common way to refer to computing capacity.
