A computer has many resources. A resource can be memory, disk drive, network bandwidth, battery power, or a monitor. It can also be system objects such as shared memory or a linked list data structure. This principle is based in object-oriented programming (OOP). In OOP, a class definition encapsulates all data and functions to operate on the data. The only way to access a resource is through the provided interface. Which security principle are we referring to
Answer:
The security principle being referred to here is:
Resource Encapsulation.
Explanation:
Resource Encapsulation is one of the cybersecurity first principles. It allows access or manipulation of the class data as intended by the designer. The cybersecurity first principles are the basic or foundational propositions that define the qualities of a system that can contribute to cybersecurity. Other cybersecurity first principles, which are applied during system design, include domain separation, process isolation, modularization, abstraction, least principle, layering, data hiding, simplicity, and minimization.

JavaFX application for the Sublime Sandwich Shop. The user can order sandwiches by using list boxes and the application displays the price. Each sandwich should allow a choice of at least three main ingredients (chicken, for example) at three different prices. The user should also be able to choose between three different bread types. Use CheckBoxes for additional ingredients - lettuce, tomato, etc.
Create an ArrayList to hold all of the sandwiches associated with an order. Display information about all the sandwiches that were ordered.

A good machine should have the mechanical advantage of......?
Answer:
The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, the so-called run-to-rise ratio. The mechanical advantage increases as the slope of the incline decreases, but then the load will have to be moved a greater distance.

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer
Answer:
c. Copy the executable file to the user’s computer
Explanation:
When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.
To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.
The program will work fine without errors.
However, do not mistake the executable file for the source file. The source file ends in .cpp.

g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

Why are data silos problematic?
Answer:
Hampers collaboration
Resource wastage
Lack of data integrity
Explanation:
Data silos comes into play When different departments of an orgainiziations independently collects data needed for its operations. The finance, HR, administrative departments and so on collects their data and keeps it to themselves. As a result there is a repetitive and needless gathering and storage of already existing data, that is the data required by one group will have to be gathered again while it currently exists with another group. This leads to inefficient resource management and wastage. This practice also leads to data integrity as data stored differently across departments becomes inconsistent and less accurate over time. Team work and collaboration is gradually eroded as each group continues to hold on to its resources which poses a problem towards organizational growth.
The tax calculator program of the case study outputs a floating-point number that might show more than two digits of precision. Use the round function to modify the program to display at most two digits of precision in the output number.
Answer:
Explanation:
The following code is written in Python. The tax calculator program was not provided, therefore I created a tax calculator that takes in the total price as an input and adds a 7% tax to it. Then it uses the round() function to make sure that the total is outputted as a decimal with two decimal digits at most.
def taxCalculator(price):
total = price * 1.07
formattedTotal = round(total, 2)
return formattedTotal
Write a program that takes a date as input and outputs the date's season. The input is an integer to represent the month and an integer to represent the day. Ex: If the input is: 4 11 the output is: spring In addition, check if both integers are valid (an actual month and day). Ex: If the input is: 14 65 the output is: invalid The dates for each season are: spring: March 20 - June 20 summer: June 21 - September 21 autumn: September 22 - December 20 winter: December 21 - March 19
Answer:
Explanation:
The following program is written in Java. It is a function that takes in the two parameters, combines them as a String, turns the combined String back into an integer, and uses a series of IF statements to check the parameters and determine which season it belongs to. Then it prints the season to the screen. The code has been tested with the example provided in the question and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
getSeason(4, 65);
getSeason(4, 11);
}
public static void getSeason(int month, int day) {
String combined = String.valueOf(month) + String.valueOf(day);
int combinedInt = Integer.parseInt(combined);
if ((month > 0 && month < 12) && (day > 0 && day < 31)) {
if ((combinedInt >= 320) && (combinedInt <= 620)) {
System.out.println("The Season is Spring");
} else if ((combinedInt >= 621) && (combinedInt <= 921)) {
System.out.println("The Season is Summer");
} else if ((combinedInt >= 922) && (combinedInt <= 1220)) {
System.out.println("The season is Autumn");
} else {
System.out.println("The Season is Winter");
}

return i
print ( summation(l, r))
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Answer:
The program in Python is as follows:
current_price = int(input("Current Price: "))
last_price = int(input("Last Month Price: "))
change = current_price - last_price
mortgage = (current_price * 0.051) / 12
print('Change: {:.2f} '.format(change))
print('Mortgage: {:.2f}'.format(mortgage))
Explanation:
This gets input for current price
current_price = int(input("Current Price: "))
This gets input for last month price
last_price = int(input("Last Month Price: "))
This calculates the price change
change = current_price - last_price
This calculates the mortgage
mortgage = (current_price * 0.051) / 12
This prints the calculated change
print('Change: {:.2f} '.format(change))
This prints the calculated monthly mortgage
print('Mortgage: {:.2f}'.format(mortgage))
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='0.\n')
