I don't know where to ask this question so I posted it here.

I see that in Ubuntu the sign for Gigabytes, Megabyte etc are used as GiB, MiB etc. So my question is: What is the reason for using i between GB.

1KB = 10^3 = 1000, 1KiB = 2^10 = 1024

1MB = 10^6 = 1000000, 1MiB = 2^20 = 1048576

and so on ;)

An KB is actually 1024 B. However, some people (like hard disk manufacturers) use 1 KB = 1000 B, because K means 1000 (like KG, KM) or in case of hard disk manufacturers because their hard drives appear to have more space (or that's what I would do). If you see KiB it is always 1024 B.
