My question is this, while taking some courses Im asked to convert bytes to kb or MB to GB. Well my numbers are off and a coworker told me sometimes they convert using Binary and sounded like I was going by Decimal? So in a question I am asked to move files and that the syntax has to be (robocopy) max: n where n is the number in bytes. So if they asked to move files that are no more then 10 KB I thought it was 10000, the answer claimed it to be 10241?
Thanks
There is a whole insane debate on this issue here
So the break down is this:
1000 kilobytes mathematically is 2^10 bytes =1024 bytes. This is working off the fact that a byte is technically 2 nibbles = 8 bits
1mb has always been 2^20 = 1024 kilobytes
1gb has always been 2^30 = 1024 megabytes
1tb has always been 2^40 = 1024 gigabytes
Hardware manufacturers and software developers still refer the math. Everyone else refers to a generic sense of rounding of the few extra bits. So to differentiate the match from the marketing...newer terms have been implemented... giby..mebi...etc to refer to the math..
When using something like robocopy, it's based on programming and exactness rather than a rounding off nature of numbers. so you get 1024.1..etc.
