De Byte [baɪt] ass e Begrëff aus der Digitaltechnik an Informatik, dee fir eng Zesummenstellung vu puer (haut bal ëmmer 8) Bit gebraucht gëtt. Am Fall wou et sech ëm 8 Bit handelt, gëtt de Byte als Oktett (fr. octet) bezeechent.
| Prefix | Numm | SI Bedäitung | binär Bedäitung | Differenz an der Gréisst |
|---|---|---|---|---|
| K or k | kilo | 103 = 10001 | 210 = 10241 | 2.40% |
| M | mega | 106 = 10002 | 220 = 10242 | 4.86% |
| G | giga | 109 = 10003 | 230 = 10243 | 7.37% |
| T | tera | 1012 = 10004 | 240 = 10244 | 9.95% |
| P | peta | 1015 = 10005 | 250 = 10245 | 12.59% |
| E | exa | 1018 = 10006 | 260 = 10246 | 15.29% |
| Z | zetta | 1021 = 10007 | 270 = 10247 | 18.10% |
| Y | yotta | 1024 = 10008 | 280 = 10248 | 20.90% |
1998, huet d'IEC, an dunn den IEEE, nei Standarde fir d'binaire Prefixe publizéiert:
| Prefix | Numm | SI Bedäitung | binär | Differenz an der Gréisst |
|---|---|---|---|---|
| Kibi | binary kilo | 1 kibibyte (KiB) | 210 bytes | 1024 bytes |
| Mebi | binary mega | 1 Mebibyte (MiB) | 220 bytes | 1024 KiB |
| Gibi | binary giga | 1 Gibibyte (GiB) | 230 bytes | 1024 MiB |
| Tebi | binary tera | 1 Tebibyte (TiB) | 240 bytes | 1024 GiB |
| Pebi | binary peta | 1 Pebibyte (PiB) | 250 bytes | 1024 TiB |
| Exbi | binary exa | 1 Exbibyte (EiB) | 260 bytes | 1024 PiB |
