Question
9)The table lists conflicting prefix meaning for Decimal and Binary values
a) Define each of the standards/groups involved {SI, IEC, JEDEC}
b) Explain in what circumstances usage of the SI or IEC respectively prefixes are appropriate.
c) What is the percentage discrepancy between the two meanings at the K and G magnitude levels?
d) In the context of microprocessor systems, what should be the most common usage of the IEC prefixes?
Prefixes for multiples of bits (bit) or bytes (B) Decimal Binary Value SI Value IEC JEDEC 1000 k kilo 1024 Ki kibi K kilo 10002 M mega 10242 Mi mebi M mega 10009 G giga 10243 Gi gibi G giga 10004 T tera 1024+ Ti tebi 10005 P peta 10245 Pi pebi 10000 E exa 10240 Ei exbi 1000 Z zetta 1024' Z i zebi 10005 Y yotta 10243 Yi yobi V.T. EExplanation / Answer
Definations are as follows:
1. JEDEC: Its basically a memory standard and its provides the specifications for the various semiconductor memory circuits. JEDEC stands for Joint Electron Device Engineering council.
2. SI: It stand for International System of Units. Its mostly used as an system for measurement.
3. IEC: Its stand for International Electrotechnical Commission. Its also an international organization of standards.
The circumstances where usage is appropirate are:
i) In electrial engineering problems calculation we can use these standards
ii) As all computer science students count all the things in powers of two , so these stands can be used there also.
In microprocessor systems varioius calculations and manipulations are being done in IEC stands. So you can say that IEC stands are the core of any microprocessor systems
