Editing Binary prefix (section)

=== Consumer confusion ===
The ambiguous meanings of "kilo", "mega", "giga", etc., has caused significant [[consumer confusion]], especially in the [[personal computer]] era. A common source of confusion was the discrepancy between the capacities of hard drives specified by manufacturers, using those prefixes in the decimal sense, and the numbers reported by operating systems and other software, that used them in the binary sense, such as the [[Timeline of binary prefixes#Mac1984|Apple Macintosh]] in 1984. For example, a hard drive marketed as "1&nbsp;TB" could be reported as having only "931&nbsp;GB". The confusion was compounded by fact that RAM manufacturers used the binary sense too.
