Since the first disk drive, the IBM 350, disk drive manufacturers expressed hard drive capacities using decimal prefixes.

This definition is synonymous with the unambiguous unit gibibyte.

This usage is widely promulgated by some operating systems, such as Microsoft Windows in reference to computer memory (e.g., RAM). The binary definition uses powers of the base 2, as does the architectural principle of binary computers.

The file manager of Mac OS X version 10.6 and later versions are a notable example of this usage in software, which report files sizes in decimal units. This definition is used in networking contexts and most storage media, particularly hard drives, flash-based storage, and DVDs, and is also consistent with the other uses of the SI prefix in computing, such as CPU clock speeds or measures of performance. This is the recommended definition by the International Electrotechnical Commission (IEC). 1 GB = 1 000 000 000 bytes (= 1000 3 B = 10 9 B)Д«ased on powers of 10, this definition uses the prefix giga- as defined in the International System of Units (SI).Nevertheless, the term gigabyte continues to be widely used with the following two different meanings: By the end of 2007, the IEC Standard had been adopted by the IEEE, EU, and NIST, and in 2009 it was incorporated in the International System of Quantities. In 1998 the International Electrotechnical Commission (IEC) published standards for binary prefixes, requiring that the gigabyte strictly denote 1000 3 bytes and gibibyte denote 1024 3 bytes. As 1024 (2 10) is approximately 1000 (10 3), roughly corresponding to SI multiples, it was used for binary multiples as well. The latter binary usage originated as compromise technical jargon for byte multiples that needed to be expressed in a power of 2, but lacked a convenient name.

The term gigabyte has a standard definition of 1000 3 bytes, as well as a discouraged meaning of 1024 3 bytes. This 2.5 inch hard drive can hold 500 GB (i.e., 500 billion bytes) of data. Using the ISQ definitions, the '372 GB' reported for the hard drive is actually 372 GiB (400 GB). With these prefixes, a memory module that is labeled as having the size ' 1 GB' has one gibibyte ( 1 GiB) of storage capacity.

To address this ambiguity, the International System of Quantities standardizes the binary prefixes which denote a series of integer powers of 1024. Hard disk capacities are described and marketed by drive manufacturers using the standard metric definition of the gigabyte, but for example, when a 400В GB drive's capacity is displayed by Microsoft Windows, it is reported as 372В GB, using a binary interpretation. Thus the use of gigabyte may be ambiguous.

However, the term is also used in some fields of computer science and information technology to denote 1 073 741 824 (1024 3 or 2 30) bytes, particularly for sizes of RAM. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard drives, solid state drives, and tapes, as well as data transmission speeds. Therefore, one gigabyte is one billion bytes. The prefix giga means 10 9 in the International System of Units (SI).

This should come as no surprise, as the typical storage capacity of a smartphone is now generally between 2 and 4 gigabytes.The gigabyte ( / Л€ ЙЎ ЙЄ ЙЎ Й™ b aЙЄ t, Л€ dК’ ЙЄ ЙЎ Й™ b aЙЄ t/) is a multiple of the unit byte for digital information. So, we can see how these numbers will exponentially add up. To make sense out of this large figure, let's use it in reference: This second figure will often be used when speaking about different sizes of RAM within an operating system. Still, many fields of computer science will refer to this number as 1,073,741,824 (1,024^3) bytes. What is a gigabyte?ДЄ gigabyte is the equivalent of 1,000,000,000 bytes. Every other form of computing measurement is based off of the humble (and yet very important) bit. A bit is the simplest unit of data storage and its value can represent a 0 or a 1 at any give time. You might not be aware that the term 'bit' is actually a shorter version of the phrase binary digi t. Figures rounded to a maximum of 5 decimal places (7 with smaller numbers).ДЄdvertisement How many bits are there in 1 gigabyte?
