Only CPUs and RAM use 1024. Floppy disks and hard drives going way back to the 1970's used 1000. In software, both are used depending on the context (and also obviously depending on the software). Most modern operating systems use 1024 for RAM and 1000 for file sizes (in the early days of computing, that agreed upon approach didn't exist, and it varied from one computer to the next).
@smokin_shinoby's tech school was shit. There has never been consistency on this issue and it's really sad that they failed to teach both numbering systems as they are (and always were) widely used.
Fair on the floppy thing. I was too young to have worried about that.
