Bits et octets
| bit |
octet (byte) |
Ko (KB) | Mo (MB) |
Go (GB) |
To (TB) |
|
| 1 bit | 1 | |||||
| 1 octet (byte) | 8 | 1 | ||||
| 1 Ko (KB) | 8 192 | 1024 | 1 | |||
| 1 Mo (MB) | 8 388 608 | 1 048 576 | 1024 | 1 | ||
| 1 Go (GB) | 8 589 934 592 | 1 073 741 824 | 1 048 576 | 1024 | 1 | |
| 1 To (TB) | 8 796 093 022 208 | 1 099 511 627 776 | 1 073 741 824 | 1 048 576 | 1024 | 1 |
Exemple de lecture du tableau : 1 Mo = 1 048 576 octets
1 octets = 1 byte
1 Ko = 1 KB
1 Mo = 1 MB
1 Go = 1 GB
1 To = 1 TB
| bit | Kb | Mb | Gb | |
| 1 bit | 1 | |||
| 1 Kb | 1 000 | 1 | ||
| 1 Mb | 1 000 000 | 1 000 | 1 | |
| 1 Gb | 1 000 000 000 | 1 000 000 | 1 000 | 1 |
Exemple de lecture du tableau : 1 Kb = 1000 bits
| Ko | = | Kilo-octet | Mo | = | Méga-octet | Go | = | Giga-octet | To | = | Tera-octet | |||
| KB | = | Kilobyte | MB | = | Megabyte | GB |
=
|
Gigabyte | TB | = | Terabyte | |||
| Kb | = | Kilobit | Mb | = | Megabit | Gb |
=
|
Gigabit | Tb | = | Terabit |
et voila
