Answer:

ALU :An arithmetic logic unit (ALU) is a digital circuit used to perform calculations and logic operations

Registers:register holds the address of memory where CPU wants to read or write data.

CU:The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor.

BIU:BIU takes care of all data and addresses transfers on the buses for the EU like sending addresses, fetching instructions from the memory, reading data from the ports and the memory as well as writing data to the ports and the memory.

Cache:Cache is used to temporarily hold instructions and data that the CPU is likely to reuse.

FPU:A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers.

Write a program to read a list of exam scores given as integer percentages in the range 0-100. Display the total number of grade

Tju [1.3M]

Answer:

import java.util.Scanner;

public class Program

{

public static void main(String [] Args)

{

int totalAGrades = 0, totalBGrades = 0, totalCGrades = 0, totalDGrades = 0, totalFGrades = 0, counter=0,maximum = 0, minimum = 9999, num, total = 0,smallest = 0,largest = 0;

Scanner in = new Scanner(System.in);

System.out.println("Enter exam percentage: ");

System.out.println("Enter a negative examScore: ");

int examScore = in.nextInt();

while(examScore > 0)

{

counter++;

if(examScore < 0){

break;}

else if(examScore > maximum){

maximum = examScore;}

else if(examScore < minimum) {

minimum = examScore;}

total = total + examScore;

if(examScore <= 50 && examScore>0)

smallest = examScore;

if(examScore > 90 && examScore <=100)

largest = examScore;

if(examScore>=90 && examScore<=100)

totalAGrades++;

else if(examScore>=80 && examScore<=89)

totalBGrades++;

else if(examScore>=70 && examScore<=79)

totalCGrades++;

else if(examScore>=60 && examScore<=69)

totalDGrades++;

else if(examScore>=0 && examScore<=59)

totalFGrades++;

examScore = in.nextInt();

}

System.out.println("Total number of scores is = " + counter );

System.out.println("Total Number of each Letter grade : " + counter);

System.out.println("Percentage of total for each letter grade : ");

System.out.println("Total number of A grades = "+ totalAGrades);

System.out.println("Total number of B grades = "+ totalBGrades);

System.out.println("Total number of C grades = "+ totalCGrades);

System.out.println("Total number of D grades = "+ totalDGrades);

System.out.println("Total number of F grades = "+ totalFGrades);

System.out.println("Lowest exam Score is :"+smallest);

System.out.println("Highest exam Score is :"+largest);

System.out.println("Average exam Score = "+ (total / counter));

}

Explanation:

Get the exam information from user as input and run a while loop until examScore is greater than zero.
Use conditional statement to check the scores of students and increment the relevant grade accordingly.
Finally display all the information including grades and scores.
