2- A bus-organized CPU has registers with 36 bits each, an ALU and a destination decoder. The control word is given below. output Clock Input R1 R2 PN SETA SRT. Toad MUX MUX A bles BELLE decoder +||+ SET. D Arit 11 logic (ALU) OPR Output SELA SELB SELD OPR i- Complete the missing bits of the control word if the number of registers is 60 and the number of operations is 30 SELECTA SELECTB SELECTD OPR ii- How many multiplexers in the A-B buses, and what is the size of each multiplexer? BUSA BUSB MUX inputs to output iii- If the data transfer from each register to MUXA=15 ns, MUXB=15 ns and ALU needs 35 ns to produce an output, what is the total time needed to output the result of an operation that needs data from registers? iv. How many inputs and outputs are there in the ALU for data? ALU inputs ALU outputs

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.

You will be given two character arrays of the same size, one will contain a number of ships. ships will move around the character array based on which way they are facing and the route they are on. routes are given in the other array. the route consists of '-' and '|' for straight paths, '\' and '/' for curves, and '+' for intersections. there are ships on these routes. ships always face a direction, '^' for up, '> ' for right, 'v' for down, and '< ' for left. any time the ships hit a '\' or a '/' it will turn as you would expect a ship to turn (e.g. a '^' that moves into a '/' will turn right). at an intersection, ships will always continue straight through. all ships move at the same speed, ships take turns moving and all ships move during one 'tick'. the one in the most top left goes first, followed by those to its right, then the ones in the next row. it iterates along the rows and then down the columns. each ship moves one space on its turn moving along the route. your function needs to return the position of the first collision between two ships and the number of ticks before the crash occurred.
