C. synchronous, parallel transfer using start and stop bits. D. synchronous, serial transfer using start and stop bits. 8. What links the design/graphics computer and the dedicated machine control com- puter in a CAD/CAM system? A. Mini-floppy disk drive programs B. Machine control programs on paper tape C. Coordinate measurement machine D. Graphics plotter and digitizer 9. In the diagram of an industrial work table drive system shown here, block 1 is a /an and block 2 is a/an A. ADC, ADC B. ADC, DAC C. DAC, ADC D. DAC, DAC MPU SYSTEM 2 AMP SIG CONDX SENSOR DC MTR WORKPIECE LEAD SCREW The X random variable shows the data transfer rate (MB/s) on a particular type of computer. The average rate of data transfer rate u and variance is o^2 and has a normal distribution a) When the data transfer rate 190 MB/s and 200 MB/s values are converted to standard normal it corresponds to == -1.1 and == 0.9, respectively. find the average and variance of this distribution? b)What is the probability that the data transfer rate is between 185 MB/s and 210 MB/s? c)What is the highest transfer rate of, 14% of the slowest transferred data? d)what is the probability of 25 similar computers has an average of 197 MB/s and MORE data transfer speed?
