K, M, G, T vs. Ki, Mi, Gi, Ti

This technical article clarifies the distinction between decimal (kilo, mega, giga, tera) and binary (kibi, mebi, gibi, tebi) unit prefixes. It explains that frequencies and data rates use base-10, while memory sizes traditionally use base-2, though the KiB/MiB notation is preferred. The post highlights real-world confusion in marketing, like drive capacities vs. network speeds, and the growing percentage difference between units like TB and TiB.
