A. Assume a computer has a physical memory organized into 64-bit words. Give the word address and offset within the word for eac

h of the following byte addresses:
0, 9, 27, 31,120, and 256.

b. Extend the above exercise by writing a computer program that computes the answer. The program should take a series of inputs that each consist of two values: a word size specified in bits and a byte address. For each input, the program should generate a word address and offset within the word. Note: although it is specified in bits, the word size must be a power of two bytes.

Answer:

Check the explanation

Explanation:

For 9th byte , it is from 8*8 bit to 9"8th bit so each word consists of 64 bits , to find word address u have to divide 8*8 by 64.

Offset within word = 9*8modulo 64.

For 27th byte , word address = 8*27/64.

Offset within word = 27* 8 modulo 64

For 21th byte , word address = 8*31/64

Offset within the word = 31*8 modulo 64

For 120 , word address = 8*120/64

Offset within the word = 120*8 modulo 64.

2.1 Changes in which factors could cause aggregate demand to shift from AD to AD1? What could happen to the unemployment rate? W
katrin [286]

Answer:

There are many factors that cause aggregate demand to shift from AD to AD1. The unemployment rate will fall and inflation will increase.

<u>Explanation:</u>

A Shift in aggregate demand from AD to AD1 means there has been a  fall in demand. Various factors that cause demand to decrease are:

  1. Increase in price of a good itself
  2. Increase in the price of complimentary goods-This will lead to a fall in demand. Like ink and pen are complementary goods. if the Price of ink increases then demand for pen will decrease.
  3. A Decrease in the price of substitute goods-Like tea and coffee.
  4. Expectation regarding future fall in price

So due to the decrease in demand finally the unemployment will increase and with that, the inflation rate will increase making  things dearer.

#include
gavmur [86]

Answer:

See explaination

Explanation:

#include <fstream>

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Fill in the code to define payfile as an input file

ifstream payfile;

float gross;

float net;

float hours;

float payRate;

float stateTax;

float fedTax;

cout << fixed << setprecision(2) << showpoint;

// Fill in the code to open payfile and attach it to the physical file

// named payroll.dat

payfile.open("payroll.dat");

// Fill in code to write a conditional statement to check if payfile

// does not exist.

if(!payfile)

{

cout << "Error opening file. \n";

cout << "It may not exist where indicated" << endl;

return 1;

}

ofstream outfile("pay.out");

cout << "Payrate Hours Gross Pay Net Pay"

<< endl << endl;

outfile << "Payrate Hours Gross Pay Net Pay"

<< endl << endl;

// Fill in code to prime the read for the payfile file.

payfile >> hours;

// Fill in code to write a loop condition to run while payfile has more

// data to process.

while(!payfile.eof())

{

payfile >> payRate >> stateTax >> fedTax;

gross = payRate * hours;

net = gross - (gross * stateTax) - (gross * fedTax);

cout << payRate << setw(15) << hours << setw(12) << gross

<< setw(12) << net << endl;

outfile << payRate << setw(15) << hours << setw(12) << gross

<< setw(12) << net << endl;

payfile >> hours ;// Fill in the code to finish this with the appropriate

// variable to be input

}

payfile.close();

outfile.close();

return 0;

}

Robert's computer is not starting due to an error in the BIOS. Which of these chips could have malfunctioned? Select the correct
timofeeve [1]

Hi;

In the question, Robert gives the explanation that there is an error in the BIOS. A BIOS (Standing for Basic Input & Output System) is a ROM chip, and is vital for the computer to initialize devices such as RAM, the CPU, etc. If there is ever an error there, a computer simply cannot boot.

From the options given, your answer given would be C. ROM.

I hope this helps!
