 Data storage

 
Data storage volume is commonly quoted in base10, as are most other units. However, in computer science base2 units are more convenient. Thus, two very similar sets of units developed, one based on a multiples of 1000, and the other on multiples of 1024.
 
While many encourage the use of the form "GiB" for binary units (as used here), this practice is not universal. The term "GB" is therefore ambiguous unless it is explicity stated to be binary or decimal. The discrepancy between binary and decimal data storage units has been a matter of some controvesy, with suggestions that it can be used for marketing putposes or to deceive without explicity lying.
