The speed inscriptions are average practical values, not the theoretical maximal values. For DSL and optical fiber, there are many more speed rates. With many and small files, the transfer speed can decrease. The conversion factor for the prefixes is 1000, e.g. 1 GB = 1000 MB. If you want to know how fast your internet connection is, search for "internet speed test".
