CASE II AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosin

g between two (2) CPU (CPUA and CPUB) implementations based on their performance. Both CPU are expected to have the same instruction set architecture. CPUA has a clock cycle time of 60 ns and CPUB has a clock cycle time of 75 ns. The same number of a particular instruction type is expected to be executed on both CPUs in order to determine which CPU would executes more instructions. CPUA is able to execute 2MB of instructions in 5*106 clock cycles. CPUB executes the same number of instructions in 3*106 clock cycles. a) Using the MIPS performance metric, which of the two (2) CPU should be selected to be implemented in the new computer system. Justify your choice. b) Compute the execution time for both CPUs. Which CPU is faster?

Answer:

(a)The CPU B should be  selected for the new computer as it has a low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A.

(b) The CPU B is faster because it executes the same number of instruction in a lesser time than the CPU A .

Explanation:

Solution

(a)With regards to  the MIPS performance metric the CPU B should be chosen for the new computer as it low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A and when we look at the amount of process done by the system , the CPU B is faster when compared to other CPU and carries out same number of instruction in time.

The metric of response time for CPU B is lower than the CPU A and it has advantage over the other CPU and it has better amount as compared to CPU A, as CPU B is carrying out more execution is particular amount of time.

(b) The execution can be computed as follows:

Clock cycles taken for a program to finish * increased by the clock cycle time = the Clock cycles for a program * Clock cycle time

Thus

CPU A= 5*10^6 * 60*10^-9 →300*10^-3 →0.3 second (1 nano seconds =10^-9 second)

CPU B= 3 *10^6 * 75*10^-9 → 225*10^-3 → 0.225 second

Therefore,The CPU B is faster as it is executing the same number of instruction in a lesser time than the CPU A

Match the installation type to its description.
MariettaO [177]

Answer:

Following are the types of installation matched to its respective definitions.

<h3>Upgrade installation:</h3>

What you do when you have a computer with an existing operating system that needs to be upgraded.

This means that while working on a window when you get attracted by the update introduced recently and you upgrade your window accordingly.

For example: Updating a window from 8 to 10 or desired features.

<h3>Multiple boot installation:</h3>

What you do when you have several operating systems on one computer.

In this type of installation, a computer has different windows for different accounts. You can boot to the desired installed window by switching account.

<h3>Clean installation:</h3>

What you do on a brand new computer that has never been set up before and does not have an operating system on it yet.

It can be defined as the installation of window done very first time on to the computer. Sometimes when the window gets deleted due to virus or any other factor, the installation at that time will also be termed as Clean Installation.

Write a fragment of code that will test whether an integer variable score contains a valid test score. Valid test scores are in
Klio2033 [76]

Answer:

Following are the code in the C Programming Language.

//set integer datatype variable

int score;

//check condition is the score is in the range of 0 to 100

if(score > 0 && score < 100){

//print if condition is true

printf("Valid test scores");

}else{

//otherwise print the following string.

printf("test scores are Invalid");

}

Explanation:

<u>Following are the description of the code.</u>

In the following code that is written in the C Programming Language.

  • Set an integer data type variable i.e., score.
  • Then, set the if conditional statement to check the condition is the variable "score" is greater than 0 and less the 100.
  • If the following statement is true then print "Valid test scores".
  • Otherwise, it print "test scores are Invalid".

You are to calculate the property tax for tax payers. You will ask the county tax clerk if they want to run the program and init
andre [41]

Answer:

Explanation:

The following code is written in Java. It creates the loop as requested and validates the information provided before continuing, if the information is invalid it prints "Invalid Information to the screen" and asks the user to enter the information again. Finally, outputing all the requested information at the end of the program. The code has been tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int totalValues = 0;

       int totalTaxes = 0;

       int count = 0;

       while(true) {

           int lotNumber, value;

           double tax;

           System.out.println("Would you like to add an Entry: 1=Yes 0=No");

           int answer = in.nextInt();

           if (answer == 1) {

               System.out.println("Please enter lot number: ");

               lotNumber = in.nextInt();

               if ((lotNumber >= 0) && (lotNumber <= 999999)) {

                   System.out.println("Please enter assessed value: ");

                   value = in.nextInt();

                   tax = value * 0.05;

                   System.out.println("Lot Number: " + lotNumber);

                   System.out.println("Property Value: " + value);

                   System.out.println("Property Tax: " + tax);

                   totalTaxes += tax;

                   totalValues += value;

                   count += 1;

               } else {

                   System.out.println("Invalid Lot Number");

               }

           } else {

               break;

           }

       }

       int average = totalTaxes / count;

       System.out.println("Total Property Values: " + totalValues);

       System.out.println("Total Property Taxes: " + totalTaxes);

       System.out.println("Average Property Tax" + average);

   }

}
