When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?
Answer:
I. You should enter interface configuration mode.
II. Configure the IP address and subnet mask.
Explanation:
A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.
Some examples of network nodes are modem, hubs, computer, switches, phone and printers.
In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.
In Cisco devices, there are five (5) main types of command modes;
1. Sub-interface configuration mode.
2. Interface configuration mode.
3. Line configuration mode.
4. Router configuration method.
5. Global configuration mode.
Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.
In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;
I. You should enter interface configuration mode using the "configure terminal" command.
II. Configure the IP address and subnet mask.
See an example below;
"Router(config-if)# IP address 192.168.1.2 255.255.255.0"
Select the correct statement(s) regarding PONS. a. only MMF cables can be used, since MMF enables greater data capacities compared to SMF b. PONS systems require active amplifiers, since high frequency signals attenuate quickly over distance c. PONS systems use passive devices between OLT and ONT d. all are correct statements
Answer:
The correct statement regarding PONS is:
c. PONS systems use passive devices between OLT and ONT
Explanation:
PON means Passive Optical Network. Based on fiber-optic telecommunications technology, PON is used to deliver broadband network access to individual end-customers. It enables a single fiber from a service provider to maintain an efficient broadband connection for multiple end-users (homes and small businesses). OLT means Optical Line Terminal, while ONT means Optical Network Terminal. They provide access to the PON.

This criterion is linked to a Learning OutcomeCreate checkDuplicates method that receives an array of ints, and an int as parameters. It will return true if the int is found in the array, and false if the int is NOT found in the array. Call the checkDuplicates method from both the MegaMillionsLottery constructor, and the getUserPicks() method.
Answer:
Explanation:
The MegaMillions Lottery class was not provided and neither was the getUserPicks() method. Since they were not found online either, I have created the checkDuplicates method so that it works standalone. Therefore, you can simply call the method from wherever you need by pasting the call line where it needs to be called. A test case has been created in the main method so that you can see the method in action. The output is seen in the attached image below.
public static boolean checkDuplicate(int[] myArr, int element) {
for (int x : myArr) {
if (x == element) {
return true;
}
}
return false;

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:

when describing a software lincense what does the phrase "open source" mean?
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

If one wish to create a loop such that it will continuously add time elapsed between two functions with variable computation time until 1 hour is passed, what type of loop would be best
"Between two functions" not sure of what you mean there but here's a quick way to execute a function for an hour
Answer and Explanation:
var interval=setInterval(function(){
var i=0;
for (i=0; i <=60; i++){
for (i=0; i <70; i++){
console.log(i); }
}}, 60000);
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.

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);
}
}

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.

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.
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:
Please find the attachment file.
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.
