Explanation:
A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.
Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.
Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
Basically, a DHCP server is designed to automatically assign internet protocol (IP) address to network devices connected to its network using a preconfigured DHCP pool and port number 67.
On a related note, when a computer that is configured with DHCP cannot communicate or obtain an IP address from the DHCP server, the Windows operating system (OS) of the computer automatically assigns an IP address of 169.254.33.16, which typically limits the computer to only communicate within its network.

While using PERT (Program Evaluation Review Technique) and CPM (Critical Path Method) techniques, activities that are on the critical path are more flexible than those activities which are not on the critical path.
a. True
b. False
Answer:
b. False
Explanation:
The Critical Path Method(CPM) is used to determine the maximum time to finish a project based on the total maximum time of the network of interdependent activities in the project. The CPM is usually used in conjunction with the Program Evaluation Review Technique(PERT). If an activity is in the critical path then it is at its maximum or longest duration time and cannot be more flexible at this point.
The process by which the kernel temporarily moves data from memory to a storage device is known as what?
Answer: Swapping
Explanation:
Swapping is referred to as the process by which the kernel temporarily moves data from memory to a storage device.
Swapping is simply a memory management scheme whereby the process can be swapped temporarily from the main memory to the secondary memory in order for the main memory to be available for other processes. Swapping is used for memory utilization.
Study the following two class interfaces: class Question { public: Question(); void set_text(string new_text); void set_answer(string new_answer); void display() const; private: string text; string answer; }; class ChoiceQuestion : public Question { public: ChoiceQuestion(); void set_text(string new_text); }; Which member function from the Question class is overridden in the ChoiceQuestion class?
Answer:
The question function
Explanation:
The ChoiceQuestion function inherits from the Question class and should have it's functions and attributes as it is now a child of the Question class. It however overides the Question class function where it sets the ChoiceQuestion class function in the first function definition of the ChoiceQuestion class definition. This allows the child class to have it's own functions as well have access to the attributes and functions of the parent class.

Imagine you are trying to choose what restaurant to visit. You have a list of restaurants, each with a collection of star ratings. You also have a minimum standard; you will only go to a restaurant whose star rating is at least your minimum standard. Write a function called restaurant_rating. restaurant_rating has two parameters. The first is a dictionary, where the keys are restaurant names and the values are lists of ratings. The second parameter is your minimum rating. If a restaurant's average rating is above your minimum rating, you might visit it. If it is not, you won't. restaurant_rating should return a list of restaurants eligible for you to visit. That is, it should return a list of restaurant names from the dictionary whose average ratings (the average of the ratings in their lists) is greater than or equal to your minimum rating. This list should be sorted alphabetically. For example: rest_and_rating
Answer:
The function in Python is as follows:
def restaurant_rating(restaurants,minRatings):
restaurantList = []
for key in restaurants:
if restaurants[key] >= minRatings:
restaurantList.append(key)
restaurantList.sort()
return restaurantList
Explanation:
This declares the function
def restaurant_rating(restaurants,minRatings):
This initializes the list of eligible restaurants
restaurantList = []
This iterates through the restaurant dictionary
for key in restaurants:
If the ratings is greater than or equal to minimum ratings
if restaurants[key] >= minRatings:
The restaurant name is appended to the restaurant list
restaurantList.append(key)
Sort the eligible lists
restaurantList.sort()
Return the list
return restaurantList
What are the types of Operating System
Answer:
1. Gestión de la memoria principal
Esta es una característica del sistema operativo básica. La memoria principal de la computadora almacena los datos que serán usados por el CPU en la ejecución de los programas. El sistema operativo se encarga de gestionarla, es decir, asignar partes de memoria a la nueva información usada, y evitar que se sature.
2. Gestión de la memoria secundaria
Es la memoria más “permanente” de una computadora. Al igual que la memoria principal, el SO sistema operativo asigna el orden de guardado en esta memoria y la mejor manera de aprovechar el espacio libre.
3. Gestión de procesos
Cuando envías un comando para que el ordenador realice una tarea, una de las funciones del sistema operativo es organizar los recursos de la computadora para ejecutarla. Esto incluye la memoria, el tiempo del CPU, los programas y archivos necesarios para ejecutar la tarea, los procesos que podrían entorpecerla y los periféricos que podrían ser necesarios para cumplirla.
4. Gestión de recursos
¡Esta es una de las características del sistema operativo más importantes! El sistema operativo coordina los recursos del hardware que integra la computadora para cumplir con las tareas requeridas. El CPU, los periféricos, las memorias principal y secundaria, los programas, todo tiene que trabajar al unísono para cumplir con las tareas de forma óptima.
5. Gestión de usuarios
El software operativo controla el acceso de los usuarios a las cuentas individuales o grupales. También, se encarga de administrar a qué recursos e información tiene acceso cada uno de ellos.
6. Gestión de la seguridad
Así como controla el acceso de usuarios, el sistema operativo también está encargado de gestionar los controles de seguridad de la computadora, entre ellos el firewall. Por ejemplo, en cuanto a la función del sistema operativo para la seguridad informática es evitar la pérdida de datos, controlar la confidencialidad de los datos y controlar el acceso a la información y a los recursos del equipo.
Write a Java program which displays a menu to allow user the following functionality: 1. Load employees’ data - prompts user for the number of employees to be loaded and then prompts for each employee name, id (5 digit number), and annual salary
Answer:
Explanation:
The code I created is written in Java. It creates an Employee class that holds the employee's name, id, and salary. Then the main method has a menu that asks the user if they want to load data, print data, or exit. Each of which is fully functioning. If the user wants to load data, it asks them how many employees they want to add and then allow them to add the employees by calling the Employee class every time and saving the objects in an ArrayList. The program has been tested and the output can be seen in the image below.
import java.util.ArrayList;
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
ArrayList<EmployeeData> companyData = new ArrayList<>();
boolean loopAgain = true;
while (loopAgain) {
System.out.println("Menu:");
System.out.println("1: Load Employee Data");
System.out.println("2: Print Employee Data");
System.out.println("3: Exit");
int answer = in.nextInt();
switch (answer) {
case 1: {
System.out.println("How many employees will you add?");
int loop = in.nextInt();
for (int i =0; i < loop; i++) {
companyData.add(new EmployeeData());
}
} break;
case 2: {
for (EmployeeData x : companyData) {
x.printData();
}
} break;
case 3: loopAgain = false; break;
}
}
}
}
class EmployeeData {
String name;
int id, salary;
public EmployeeData() {
Scanner in = new Scanner(System.in);
System.out.println("Enter Employee Name: ");
String name = in.nextLine();
System.out.println("Enter Employee ID:");
int id = in.nextInt();
System.out.println("Enter Employee Salary: ");
int salary = in.nextInt();
this.name = name;
this.id = id;
this.salary = salary;
}
public void printData() {
System.out.println("Employee: " + this.name);
System.out.println("ID: " + this.id);
System.out.println("Salary: " + this.salary);
}
}
It's currently 1:00 in the afternoon. You want to schedule the myapp program to run automatically tomorrow at noon (12:00). What two at commands could you use
Answer:
at 12 pm tomorrow
at now +23 hours
Explanation:
The at command could be used in the command line to perform a scheduled command in Unix related systems. The at command coule be ua d to program a complex script or used to perform simple scheduled reminders.
The at command is initiated by first writing the at string followed by the condition or statement to be performed.
Currently (1:00 pm) ; To make a schedule for 12pm then that will be at noon the following day:
at 12:00 pm tomorrow
Or :
Using the number of hours between the current tone and the schedule time : 12 pm tomorrow - 1:00 pm today is a difference of 23 hours ;
Hence, it can be written as :
at +23 hours
What opeartions will acquire memory from heap? Select all that apply. Group of answer choices malloc new free declaraion
Answer:
malloc, new
Explanation:
Heap memory is that part of the memory which is allocated to the JVM and it is shared by all the executing threads in the application. This memory is used by the programming languages to store the global variables. All the global variables are stored in the heap memory by default. This memory is also known as the dynamic memory.
In C programming, the library function, malloc is mainly used to allocate the block of the memory on the heap.
The new operation also acquires memory form the heap.
Thus, the answer is 'malloc' and 'new'.
For this assignment, you will use pointers to write a program that can be used to gather statistical data about the number of movies college students see in a month. The program should ask the user how many students were surveyed and dynamically allocate an array of that size. The program should then allow the user to enter the number of movies each student has seen. The program should then calculate the average, median, and mode of the values entered. Be sure to include comments throughout your code where appropriate.
Complete the C++ code
Answer:
Following are the program to the given question:
#include <iostream>//header file
#include <bits/stdc++.h>//header file
using namespace std;
int main()//main method
{
int x,i,sum=0;//defining integer variable
double average, median;//defining double variable
cout<<"How many students were surveyed? ";//print message
cin>>x;//input value
int *a = new int[x]; //dynamically created array
for(i = 0;i<x;i++)//defining for loop to input value in array
{
cout<<"Enter the number of movies seen by student number "<<i+1<<": ";//print message
cin>>a[i];//input value
}
for (int i = 0; i < x; i++)//defining loop for add value
sum += a[i]; //use sum to add array value
average = (double)sum/x;//defining average variable to calculate average
cout<<"Average is "<<average<<endl;//print average value with message
sort(a, a+x); //use sort method to sort array to find the median
if (x % 2 != 0)//use if to check the even value
median = (double)a[x/2];//calculating the median value
else//esle block
median = (double)(a[(x-1)/2] + a[x/2])/2.0;//calculating median value
cout<<"Median is "<<median<<endl;//print median value with message
int m_count=1 ,mode= a[0], c_count = 0;//defining integer variable
for( i=1;i<x;i++)//defining for loop arrenge value
{
if(a[i]==a[i-1])//use if to check array value
{
c_count++;//increment c_count variable value
}
else//else block
{
if(c_count>m_count)//use if to check c_count greater than m_count
{
m_count = c_count;//holding value in m_count
mode = a[i-1];//holding mode value
}
c_count = 1;//holding value integer value in c_count
}
}
cout<<"Mode is "<<mode;//print mode value with message
return 0;
}
Output:

Explanation:
Including header file.Defining the main method. Declaring integer and double type variables.Declaring integer array.Use the loop to the input value.After input, the value uses double variable "average, the median" that uses the for loop and conditional statement to check the value and hold in its variable.In the next step, another integer variable "m_count, mode, and c_count" is defined that uses the loop and conditional statement to check the median and mode value and hold its value into their variable.what is the printed version of what you see on the computer screen

We have an N x N square grid.
We will paint each square in the grid either black or white.
If we paint exactly A squares white, how many squares will be painted black?
A and N are integers,
Print the number of squares that will be painted black.
C++
Answer:
The solution in C++ is:
#include <iostream>
using namespace std;
int main(){
int N, A;
cout<<"Grids: "; cin>>N;
cout<<"White: "; cin>>A;
cout<<"Black: "<<N * N - A;
return 0;
}
Explanation:
This declares N and A, as integers
int N, A;
This gets inputs for N
cout<<"Grids: "; cin>>N;
This gets inputs for A, (the white grids)
cout<<"White: "; cin>>A;
This calculates and prints the number of black grids
cout<<"Black: "<<N * N - A;
PS
From the question, we understand that the grid is N by N square grids.
This means that:
[tex]Total = N * N[/tex]
So, the number of black grids is:
[tex]Black = Total - A[/tex]

A sales transaction was coded with an invalid customer account code (XXX-XX-XXX rather than XXX-XXX-XXX). The error was not detected until the updating run when it was found that there was no such account to which the transaction could be posted. A control procedure that would serve as a preventive control for this situation would be:
Answer:
a simple IF statement using Regex
Explanation:
In any coding language, a good control procedure for this would be a simple IF statement using Regex. In the IF statement you can grab the account code and compare it to a regular expression that represents the correct format. IF the account code is in the correct format (matches the regular expression), then you go ahead and save the account code for use. Otherwise, you would output an error and ask for another account code. This will prevent the program from trying to use an account code that is not valid.

Websites can send __________ to your computer that stay on your hard drive and can track your web movements. Multiple Choice freeware cookies viruses pop ups
Answer:
Cookies
Explanation:
Cookies are pieces of information stored as text strings on your computer.
A web server sends you a cookie and a web browser stores it. The browser then returns the cookie to the server the next time the page is referenced. One of the most common uses of cookies is to store user ID. For example, the cookie might contain the following ID = 456894.
An example of a website that uses a cookie is an e-commerce website. When you visit the site and fill out a form, the website assigns you a user ID, stores your information with this user ID in the database on the web server and then returns this ID to your browser as a cookie.
The next time you visit the page, the browser sends this ID to the server. The server looks up this ID and then customizes the page it sends back to you. For example, you might see on the page, "Welcome back, David!"
To dynamically change a reference line using parameter action, you first create a reference parameter. Next, add a parameter action for it. Finally, _____.a. add a reference line whose value follows a reference parameter.b. add the sheet you want to control as the bottom-right element in the layout.c. also add a URL action that points to the dashboard itself.d. add a reference line with a per pane scope and a tooltip.
Answer:
a. add a reference line whose value follows a reference parameter
Explanation:
To dynamically change a reference line using parameter action, you first create a reference parameter. Next, add a parameter action for it. Finally, "add a reference line whose value follows a reference parameter."
This is because to dynamically change a reference line using parameter action, one needs to do the following:
1. Attribute the reference line with a parameter
2. Utilize a parameter action to make the parameter interactive.
3. As your users interact with the view, the reference lines automatically update to deliver more context to the data.
Answer:
add a reference line whose value follows a reference parameter
Explanation:
add a reference line whose value follows a reference parameter

Which of the following represents knowledge as a set ofâ rules? A. Neural networks.B. Machine learning systems.C. Robotics.D. Expert systems.E. Genetic algorithms.
Answer:
D. Expert systems
Explanation:
Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.
Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.
Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;
I. Non-algorithmic processing.
II. Symbolic processing.
In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.
Hence, expert systems represents knowledge as a set of rules.
Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.
Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.
The Expert systems represent the knowledge as a set of rules. Thus option D is correct.
What is an expert system?The system is the computer-based system that emulates all decision-making abilities of man and is designed to solving the complex problems by use of reasoning through the representation of IF-THEN rules.
The expert system is divided into the two types of systems such as knowledge base and inference engines. The knowledge base shows the facts and rules. The inference applies those facts to know the rules.
