2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

JAVA

butalik [34]

Answer:

import java.util.*;

public class MyClass {

public static void main(String args[]) {

Scanner input = new Scanner(System.in);

System.out.print("Input a word: ");

String userinput = input.nextLine();

for(int i =0;i<userinput.length();i+=2) {

System.out.print(userinput.charAt(i));

}

Explanation:

This line prompts user for input

System.out.print("Input a word: ");

This declares a string variable named userinput and also gets input from the user

String userinput = input.nextLine();

The following iterates through every other character of userinput from the first using iteration variable i and i is incremented by 2

for(int i =0;i<userinput.length();i+=2) {

This prints characters at i-th position

System.out.print(userinput.charAt(i));

Molodets [167]

Answer: rootkit

Explanation:

Hi, A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.

A rootkit provides continued privileged access to a computer while hiding its presence. Because of this hiding characteristic it is very difficult to detect.

Once a rootkit has been installed, it allows someone to have total remote control of a computer and do things such as files executions and system changes.

I'm programming in javascript, I tryed to put a code like this, but it doesn't work. could someone help me?

VMariaS [17]

Answer:

Your computer does not support this code because you have put spaces in between the code, or maybe that is how you have written the question.
