A binary prefix is a unit prefix for multiples of units in data processing, data transmission, and digital information, principally in association with the bit and the byte, to indicate multiplication by a power of 2. As shown in the table to the right there are two sets of symbols for binary prefixes, one set established by International Electrotechnical Commission(IEC) and several other standards and trade organizations using two letter symbols, e.g. Mi indicating 1,048,576 with a second set esta…

- For writing, discourage use of SI prefixes in either sense (binary or decimal), and instead use, respectively, KiB/MiB/GiB/... (IEC) or KdB/MdB/GdB/... (new in this proposal, and modelled on IEC). For speaking, or writing in full, abandon the (to say it politely) "problematic" IEC pronunciation proposal, instead use SI pronunciation for both, but a...

Z4 was a relay-based machine. The corresponding contract was signed in the fall of 1949, and the machine reassembled in Zurich after its arrival in July 1950. The Z4 was replaced by ERMETH, a computer developed at the ETH in Switzerland from 1953 to 1956, one of the first electronic computers on the European continent.
