What is Gibibyte?

The gibibyte is an IEC binary prefix unit equal to exactly 2 to the 30th power bytes (1,073,741,824 bytes). Linux and many other operating systems display memory and disk capacity in gibibytes for precision. There is approximately a 7.4 percent difference between a gibibyte and the SI-based gigabyte (one billion bytes), which explains why a new hard drive appears to have less capacity than advertised.

What is Kibibyte?

The kibibyte is an IEC binary prefix unit equal to exactly 1,024 bytes (2 to the 10th power). It was introduced in 1998 to resolve the ambiguity of "kilobyte," which historically referred to both 1,000 and 1,024 bytes depending on context. In systems programming, memory page sizes (commonly 4 KiB) and buffer sizes are specified in kibibytes. The distinction matters most in large-scale computing where the cumulative difference between powers of ten and powers of two becomes significant.
