Just adding my 2 cents in here. Computer math is in Hexidecimal,
which is base 16. Versus our normal base 10. Some old PCs had
Octal (base 6). The Hexidecimal being a way for us to view
and write in a 16-bit format. Computers themselves are binary.
And binary numbers will always be a power of 2. So you have:
0, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, etc.
So, your friend is correct in a KiloByte being 1024 bytes.
And a MegaByte is 1024 x 1024.
