gigaoctet

La gigabyte (/ˈɡɪɡəbaɪt, ˈdʒɪɡə-/) is a multiple of the unit byte for digital information. The prefix giga means 109 dans le Système international d'unités (SI) (SI). Therefore, one gigabyte is un milliard de bytes. The unit symbol for the gigabyte is GB.

This definition is utilisé en all contexts of science, engineering, business, and many areas of computing, including hard drive, solid state drive, and tape capacities, ainsi que data transmission speeds. However, the term is aussi utilisé en some fields of computer science and information technology to denote 1073741824 (10243 or 230) bytes, particulièrement for sizes of RAM. The use of gigabyte may thus be ambiguous. Hard disk capacities as described and marketed by drive manufacturers using the standard metric definition of the gigabyte, but lorsque a 400 GB drive's capacity is displayed by, par exemple, Microsoft Windows, il est reported as 372 GB, using a binary interpretation. To address ce ambiguity, the International System of Quantities standardizes the binary prefixes qui denote a series of integer powers of 1024. With ces prefixes, a memory module que is labeled as having the size "1GB" has one gibibyte (1GiB) of storage capacity. Using the ISQ definitions, the "372 GB" reported for the hard drive is actually 372 GiB (400 GB). 


Bit

A bit (binary digit) is the most basic unit of digital information, representing a logical state with one of two possible values: 0 or 1. The term was coined by statistician John Tukey in 1946 and popularized by Claude Shannon in his foundational work on information theory. Eight bits form one byte, the standard unit of computer storage.
