This standard, which had been approved in 1998, introduced the prefixes kibi-, mebi-, gibi-, tebi-, pebi-, exbi-, to be used in specifying binary multiples of a quantity. In 1999, the International Electrotechnical Commission (IEC) published Amendment 2 to "IEC 60027-2: Letter symbols to be used in electrical technology - Part 2: Telecommunications and electronics". However, as computing equipment has grown in memory capacity, these differences have led to increasingly large errors when expressed as percentages. In the days of 32K RAM computers, this confusion was not serious, since the difference between 210 and 103 was approximately 2%. ![]() Floppy disk manufacturers are even more confusing. Telecommunications also uses the SI factors, so a 1 Mbit/s connection transfers 106 bits per second. Hard disk manufacturers are the only group in computing that habitually uses the lower SI factors, so what is advertised as a 30 GB hard disk will actually only hold about 28 × 2 power(30) bytes. It is widely regarded as confusing that the common usage of "kilobyte" means 1024 bytes, while the "correct" value is 1000 bytes. ![]()
