Answers of blanks:

1. 3 bits

2. 20 bits

3. 64 MB

4. 16 MB

5. 64 KB

6. 64 MB

Explanation:

Following is the solution for question step-by-step:

No. of Tag bits = No. of bits to represent

Tag bits = Main memory - cache size bits -------- (A)

Given:

Main memory = 128 KB = $2^7 * 2^{10} = 2^{17}$

Cache Memory = 16 KB = $2^4 * 2^{10}= 2^{14}$

Putting values in A:

Tag bits = 17 - 14 = 3 bits

Tag bits = Main memory - cache size bits -------- (A)

Given:

Main memory = 32 GB = $2^5 * 2^{30} = 2^{35}$

Cache Memory = 16 KB = $2^5 * 2^{10}= 2^{15}$

Putting values in A:

Tag bits = 35 - 15 = 20 bits

Given:

Tag bits = 7

Cache Memory = 512 KB = $2^9 * 2^{10} = 2^{19}$

So from equation A

7 = Main Memory size - 19

Main Memory = 7 + 19

Main memory = 26

OR

Main Memory = $2^6 * 2^{20} = 64 MB$

Given that:

Main Memory Size = $2^4 * 2^{30} = 2^{34}$

Tag bits = 10

Cache Memory Bits = 34 - 10 = 24

Cache Memory Size = $2^4 * 2^{20} = 16 MB$

Given that:

Main Memory Size = 64 MB = $2^6 * 2^{20}$

Tag bits = 10

Cache Memory Bits = 26 - 10 = 16

Cache Memory Size = $2^{16} = 2^6 * 2^{10} = 64 KB$

Cache Memory = 512 KB = $2^9 * 2^{10} = 2^{19}$

Tag Bits = 7

Main Memory Bits = 19 + 7 = 26

Main Memory size = $2^{26} = 2^6 * 2^20 = 64 MB$

i hope it will help you!

4. Give four reasons why a laptop computer is more expensive than a desktop computer of the

kipiarov [429]

<h3>ANSWER:The main reason why laptops are more expensive than desktops is in the development costs to create hardware that is compact enough and at the same time meeting an expected level of performance.</h3>

<h3>And it’s not just performance that is a big challenge. It is also keeping the system cool enough that stability is maintained under most common usage conditions</h3>

Write Java program to allow the user to input the amount of deposit, yearly interest rate (percentage), and income tax(percentag

Vedmedyk [2.9K]

Answer:

import java.util.Scanner;

public class num12 {

public static void main(String[] args) {

Scanner scr = new Scanner(System.in);

System.out.println("Enter a Deposit Amount");

double amt = scr.nextDouble();

System.out.println("Income tax in percentage");

double incomeTaxRate = scr.nextDouble()/100;

System.out.println("Yearly interest rate:");

double rate = scr.nextDouble();

double intRate = rate/100;

double interest = (amt*intRate)-(amt*incomeTaxRate);

System.out.println("The Interest on "+amt+" at "+rate+"% after one year is "+interest);

}

Explanation:

Find the sample output attached

Java's Scanner class is used to prompt and receive values for deposit amount, income tax rate and interest rate

The yearly interest is calculate by interest = (amt*intRate)-(amt*incomeTaxRate);
