How data conversion works
Data sizes come in two systems. Decimal units (kB, MB, GB, TB) step by 1,000 and are used by drive makers, networks and phone plans. Binary units (KiB, MiB, GiB, TiB) step by 1,024 and are what Windows and many apps actually count.
That gap is why a 1 TB drive shows as about 931 GB on a computer: nothing is missing, it is the same number of bytes counted in a different unit. A byte is 8 bits, so a 100 Mbps connection moves at most 12.5 megabytes per second.
