The word bit should be derived from "binary digit" (digit = finger, digit, number, bit = binary number)
and bytes come from nothing other than "bit times eight" (B-eight = byte).

 In January 1999 the International Electrotechnical Commission im Addendum to IEC 60027-2 a new standard as prefixes kibi- (kibibyte), mebi-, gibi-, etc. and the symbols Ki, Mi, Gi, etc. introduced to the multiples of Binary numbers from being confused with the SI multiples of the powers of ten to exclude. Kibibit sounds a little getting used to. This is the new standard, but hardly anyone wants to use it:

The following designations were published in IEC standard 60027-2 in December 1998
(bi stands for binary), but have not yet really caught on in practical use:

1 Kibibyte [KiB] = 1024 = 210 byte
1 Mebibyte [MiB] = 1 048 576 = 220 byte
1 Gibibyte [GiB] = 1 073 741 824 = 230 byte
1 tebibyte [TiB] = 1 099 511 627 776 = 240 byte
1 pebibyte [PiB] = 1 125 899 906 842 624 = 250 byte
1 Exbibyte [EiB] = 1 152 921 504 606 846 976 = 260 byte
1 zebibyte [ZiB] = 1 180 591 620 717 411 303 424 = 270 byte
1 Yobibyte [YiB] = 1 208 925 819 614 629 174 706 176 = 280 byte
1 Nobibyte [NiB] = 1 237 940 039 285 380 274 ​​899 124 224 = 290 byte
1 dobibyte [DiB] = 1 267 650 600 228 229 401 496 703 205 376 = 2100 byte

Calculation: transmission rates and bandwidth

Byte = the common information measure unit

bit = the common data transfer unit

1 kilobit = 1 000 bits
1 megabit = 1 000 000 bits

Files on the hard drive are in kilosbyte calculated, but transfer rates in kilosbit.
In addition, bits and bytes can be added or removed using transmission parameters.

Conclusion: A 56k modem = 56,000 bits needs = 458,753 bits to transmit a 56k file
not 1 second, but at least 8.2 seconds.
This is confusing and must always be taken into account when calculating transmission rates.

Rule of thumb: Kbyteof the file / seconds = transfer rate.

 +) With WLAn, maximum data rates of around 40% - 50% of the line capacity are achieved. *) The value is heavily dependent on the hardware used (hard drive, network card connection ...) A home PC may reach 20,000 - 45,000 kB / s (~ 20 - 45 MB / s) here

... this also applies to incorrect data.

The effective speed depends on many parameters: the hardware, the
Operating system, the provider, the network load, the connection of the target server, etc.

 In data communication, the metric definition is a kilobyte (1000 bytes per kilobyte) common and correct. The binary definition of a Kilobytes (1024 bytes per kilobyte) are used in the fields of data storage (Hard drive, memory) used, but not for bandwidth representation.
