Answer:False

Explanation: Pipeline architecture works in a way where the processing or execution of one stage is done and then processes instruction in the next stage in a sequence to achieve the good performance of program. But due to conditional branching the stalls are caused which creates error and the program has to restart from different node because sequence get disrupted.Therefore the statement given is false.

What would a world where we have 2^128 (340 undecillion) Internet connected devices look like? How could that much Internet usag

cluponka [151]

A world have 2^128 (340 undecillion) of IPv addresses that helps to connect to the internet. IPv6 addresses can make it easier for working organizational teams connecting to the Internet, IP addresses that are created by IPv6 are 128 bits.

<h3>What is internet?</h3>

Internet is the system uses the Internet protocol suite (TCP/IP) and interconnected computer networks that communicate between two or more individuals.

Today, almost 20 IP addresses are taken by7 each home for each electronic device. The internet usage is so wide, that even a simple task is not possible without it. Even a simple task can be done using internet.

If you wanted to detect x-rays coming from the sun,where would you place the detector? Why?

Temka [501]

You would place it in orbit around Earth, as most X-rays are absorbed by the atmosphere, so you would want the detector outside of the atmosphere to accurately detect the X-rays.

Suppose we wanted to make change for purchases and wanted to use the least number of coins possible. Here is a greedy algorithm:

love history [14]

Answer:

Explanation:

The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.

import math

def amountOfCoins(change):

print("Change: " + str(change))

quarters = math.floor(change / 0.25)

change = change % 0.25

dimes = math.floor(change / 0.20)

change = change % 0.20

pennies = math.floor(change / 0.01)

print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))

Design a generic post-implementation evaluation form. The form should consist of questions that you could use to evaluate any in

irina1246 [14]

Answer:

Project Identification

Provide the identifying information associated with the project, including the applicable project control code, system acronym, and system title.

System Proponent

Provide the name of the System Proponent.

History of the System

Briefly describe the system’s history and predecessor, if any. State the mission needs and information requirements, including how the system is expected to help users.

Functional System Description and Data Usage

Briefly describe what the system does functionally and how the data are used by the system.

Explanation:

Overview

The Post-Implementation Review is used to evaluate the effectiveness of the system development after the system has been in production for a period of time (normally 6 months). The objectives are to determine if the system does what it is designed to do: Does it support the user as required in an effective and efficient manner? The review should assess how successful the system is in terms of functionality, performance, and cost versus benefits, as well as assess the effectiveness of the life-cycle development activities that produced the system. The review results can be used to strengthen the system as well as system development procedures.

The review is scheduled to follow the release of a system or system revision by an appropriate amount of time to allow determination of the effectiveness of the system. A representative from the functional development group or other member of the major user organization participates in the review. The System Proponent ensures that all documentation and all personnel needed to participate in the review are accessible.

The reviewer and an assigned team collect the information needed for the Post-Implementation Review by interviewing end users and their managers, system administrators, and computer operations personnel. The report is then prepared and provided to the user organization that requested it and the information systems organization, which may jointly use the findings to initiate other actions.

The Post-Implementation Review is a free-form report, and not all sections are relevant or necessary to the final product. A description of the Post-Implementation Review Report is attached.

Answer:

maxSum = FindMax(numA, numB) + FindMax(numY, numZ);

The maxSum is a double type variable which is assigned the maximum of the two variables numA numB PLUS the maximum of the two variables numY numZ using FindMax function. The FindMax() method is called twice in this statement one time to find the maximum of numA and numB and one time to find the maximum of numY numZ. When the FindMax() method is called by passing numA and numB as parameters to this method, then method finds if the value of numA is greater than that of numB or vice versa. When the FindMax() method is called by passing numY and numZ as parameters to this method, then method finds if the value of numY is greater than that of numZ or vice versa. The PLUS sign between the two method calls means that the resultant values returned by the FindMax() for both the calls are added and the result of addition is assigned to maxSum.

Explanation:

This is where the statement will fit in the program.

#include <iostream>

using namespace std;

double FindMax(double num1, double num2) {

double maxVal = 0.0;

if (num1 > num2) { // if num1 is greater than num2,

maxVal = num1; // then num1 is the maxVal. }

else {

maxVal = num2; // num2 is the maxVal. }

return maxVal; }

int main() {

double numA;

double numB;

double numY;

double numZ;

double maxSum = 0.0;

maxSum = FindMax(numA, numB) + FindMax(numY, numZ);

cout << "maxSum is: " << maxSum << endl; }

Lets take an example to explain this. Lets assign values to the variables.

numA = 6.0

numB = 3.0

numY = 4.0

numZ = 9.0

maxSum =0.0

maxSum = FindMax(numA, numB) + FindMax(numY, numZ);

FindMax(numA,numB) method call checks if numA>numB or numB>numA and returns the maximum of the two. Here numA>numB because 6.0 is greater than 3.0. So the method returns numA i.e. 6.0

FindMax(numY, numZ) method call checks if numY>numZ or numZ>numY and returns the maximum of the two. Here numZ>numY because 9.0 is greater than 4.0. So the method returns numZ i.e. 9.0

FindMax(numA, numB) + FindMax(numY, numZ) this adds the two values returned by the method FindMax for each call.

FindMax returned maxVal from numA and numB values which is numA i.e. 6.0.

FindMax returned maxVal from numY and numZ values which is numZ i.e. 9.0.

Adding these two values 9.0 + 6.0 = 15

So the complete statement FindMax(numA, numB) + FindMax(numY, numZ) gives 15.0 as a result.

This result is assigned to maxSum. Hence

maxSum = 15

To see the output on the screen you can use the print statement as:

cout<<maxSum;

This will display 15
