he just explained it! the companies pretend that 1GB=1000mb 1mb = 1000KB and 1kb = 1000b wheras 1gb = 1024mb 1mb = 1024 kb 1kb = 1024b .. uve got 200gb of space, but each gb is only worth 1000mb, meaning ur losing 24mb each GB of space
ok bigtime this is what is happening. When you see 100 Gb advertized it is actually 100 Gb in decimal numbering. The computer dosnt read it as decimal but as binary.
Binary on left decimal on the right
0 - 0
1 - 1
10 - 2 (so what every is in the second value of binary is 2)
11 - 3
100 - 4 (the third binary value is 4... it doubles each time)
1000 - 8
10000 - 16
1000000 - 64
1000100 - 68
1000000000 - 1024 (thats a Gb in binary)
So because binary doubles each digit like that a 10 digit binary number is 1024. It sounds bigger if you put it in decimal (1000) so people will buy it dont worry tho you wernt ripped off. Its just the conversion difference.
