The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. [1] The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux , although some variants of the latter can overcome this barrier. [ 2 ]

Cookies are restricted to 4 kilobytes. Web storage provides far greater storage capacity: Opera 10.50+ allows 5 MB [1] Safari 8 allows 5 MB [5] Firefox 34 allows 10 MB [5] (formerly 5 MB per origin in 2007 [6]) Google Chrome allows 10 MB per origin (formerly 5 MB per origin) [7] Internet Explorer allows 10 MB per storage area [8]
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
However, in some areas of information technology, particularly in reference to random-access memory capacity, kilobyte instead typically refers to 1024 (2 10) bytes. This arises from the prevalence of sizes that are powers of two in modern digital memory architectures, coupled with the coincidence that 2 10 differs from 10 3 by less than 2.5%.

Other computer capacities and rates, like storage hardware size, data transfer rates, clock speeds, operations per second, etc. are usually presented in decimal units. For example, the manufacturer of a "300 GB" hard drive is claiming a capacity of 300 000 000 000 bytes, not 300 × 1024 3 (which would be 322 122 547 200) bytes.
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte . A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).
