Catherine is designing the backup strategy for the new private cloud that her company is implementing. She specifies that a full backup will be done weekly on Sunday mornings. She also specifies that another backup will be run every morning after that. Which of the following backup types will use the least amount of disk space for the daily backups?
a. Cumulative
b. Additive
c. Incremental
d. Differentia

Answers

Answer:

Incremental ( C )

Explanation:

The incremental backup system should be used since Catherine intends to backup files every morning and this is because Incremental backup  uses the least amount of disk space by simply copying data of files that have been changed after its previous backup session . Instead of copying all the files that it has previously copied in the previous backup session

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

Answers

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

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

Answers

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!"

This allows the child class to have it's own functions as well have access to the attributes and functions of the parent class.

I need to create a method named "root positive". which will either print the square root of the number passed to it or if the number is less than zero, it will print out the statement "Number must not be negative."?
1. Ask the user to input a number of type double which you will find the square root of the number.

2. Create a method called rootPositive which will either print the square root of the number passed to it or if the number is less than zero, it will print out the statement "Number must not be negative.".

3. Call your rootPositive method and pass to it the number the user enetered.

Answers

Answer:

Explanation:

The following code is written in Java. It is a method that calculates the square root of a number as requested. The method first checks with an IF statement if the parameter value is a positive number and then calculates the square root and prints it to the screen. Otherwise, it prints Number must not be negative. A test case has been provided in the main method and the output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.print("Enter a number of type double to calculate square root:");

       double num = in.nextDouble();

       rootPositive(num);

   }

   public static void rootPositive(double num) {

       if (num > 0) {

           System.out.println(Math.sqrt(num));

       } else {

           System.out.println("Number must not be negative.");

       }

   }

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.

Answers

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.

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

Answers

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);

What opeartions will acquire memory from heap? Select all that apply. Group of answer choices malloc new free declaraion

Answers

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'.

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.

c. x->id = 12345;
d. x.empl.id = 12345;

Answers

Answer:

The answer is "Option d".

Explanation:

In the above-given code, two-class is defined that is "employee and manager", in which the first class "employee" defines two variables that are "name, id". In this name is pointer type character and id is a long type variable.

In the second class "manager" one variable "rank" and the employee object is created. In this class, the rank variable is a pointer type character, and outside this class, a reference "x" is created.

In this code, we use both class object that uses the "employee" class variable that is id to hold value in it.

Answers

Answer:

Explanation:

This program is written in Python. It is a function that takes in two arrays. Then it loops through the first array twice, adding each element with the others and comparing the sum to the values in the second array. If a similar value is found in the second array, the program prints out the value and returns True to the user. Otherwise, it returns False. A test case has been created with two array variables that print out False, the output can be seen in the attached image below.

def sumArray(arr1, arr2):

   for i in range(len(arr1)):

       for x in range(len(arr1)):

           sum = 0

           if i != x:

               sum = arr1[i] + arr1[x]

           if sum in arr2:

               print(str(sum) + "Found in Second Array")

               return True

   return False

arr1 = [1, 9, 10, 44]

arr2 = [2, 4, 8, 14]
