Why does 8gb of ram display like 8192mb and not 8000mb?

Question

In informatics parts there’s always a little bit more when talking about GB or similars. Why it’s like that?

Answer 1

Because data units are binary and a whole value is always a power of two.

ie
1 byte = 8 bits (2^3)
1 kibibyte = 1024 bytes (2^10)
