Using the information below, CPU X = 0.3 ms (the average time to execute 1,000 instructions)Drive A = 0.7 ms (average data access speed)Drive B = 4 ms (average data access speed)Drive C = .03 ms (average data access speed)Calculate I/O access speed using this CPU and each of the disk drives as they evaluate the following track requests in this order: 16, 4, 9, 16, 29, 31, 5. Then, in each case, calculate the access speeds after the track requests are reordered and rank the three disk drives before and after reordering.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. internet speed levels of "fast comma " "medium comma " and "slow" choose the correct answer below. a. the ordinal level of measurement is most appropriate because the data can be ordered comma but differences left parenthesis obtained by subtraction right parenthesis cannot be found or are meaningless. nothing nothing nothing nothing nothing b. the interval level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is no natural starting point. c. the nominal level of measurement is most appropriate because the data cannot be ordered. nothing d. the ratio level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is a natural starting point.
