a) In order to execute a program, instructions must be transferred from memory along a bus to the CPU. If the bus has 8 data lines, at most one 8 bit byte can be transferred at a time. How many memory accesses would be needed in this case to transfer a 32 bit instruction from memory to the CPU?
Answer: 4 memory accesses

A particular talent competition has five judges, each of whom awards a
score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A
performer’s final score is determined by dropping the highest and the lowest score received, then
averaging the three remaining scores. Write a program that uses these rules to calculate and
display a contestant’s score. It should include the following functions:
• getJudgeData() should ask the user for a judge’s score, validate it, and then return it. This
function should be called by main once for each of the five judges.
• calcScore() should drop the highest and lowest score and then calculate and print the
average of the three scores that remain. This function should be called at least once by
main and should be passed the five scores. These averages should be rounded to the
tenths decimal place. Make sure you are rounding after your calculation (3.57 = 3.6 and
3.54 = 3.5)
Two additional functions, described below, should be called by calcScore, which uses the
returned information to determine which scores to drop.
• findLowest() should find the lowest of the five scores passed to it.
• findHighest() should find and return the highest of the five scores passed to it.
In JAVA programing
Using the C++ code we can say that it will be possible to calculate the points as follows:
Writing this code we will have:#include <iostream>
using namespace std;
void getJudgeData(double *);
void calcScore(double[], int);
double findLowest(double[], int);
double findHighest(double[], int);
int main()
{
double scores[5];

int s=5;
double avgScore;
cout << "\n Enter each Judge's score.\n\n\n";
