Answer:
B. Role-based access controls
Explanation:
Roll-based access control is a way to control access to the network and to data which depends on the position of employees in a department. This way the permission to access information are granted according to roles that are assigned to employees. This type of access control allows access privileges to employees only to the folders and data files which they need in order to perform their tasks and it does not allow them to access the data or information which is not relevant to them. This helps the department to secure the sensitive information and data files and reduces the risk of data breaches.

6.21 LAB: Swapping variables Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is:
Answer:
Here is the C++ and Python programs:
C++ program:
#include<iostream> //to use input output functions
using namespace std; //to identify objects like cin cout
void swapvalues(int& userVal1, int& userVal2); //function to swap values
int main() { //start of main function
int integer1,integer2; //declare two integers
cout<<"Enter first integer: "; //prompts user to enter the first number
cin>>integer1; //reads first number from user
cout<<"Enter second integer: "; //prompts user to enter the second number
cin>>integer2; //reads second number from user
cout<<"Integers before swapping:\n"; //displays two numbers before swapping
cout<<integer1<<endl<<integer2;
swapvalues(integer1, integer2); //calls swapvalues method passing two integers to it
cout << "\nIntegers after swapping:\n"; //displays two numbers after swapping
cout<<integer1<<endl<<integer2; }
void swapvalues(int& userVal1, int& userVal2){ //method that takes two int type numbers and swaps these numbers
int temp; //temporary variable
temp = userVal1; //temp holds the original value of userVal1
userVal1 = userVal2; //the value in userVal2 is assigned to userVal1
userVal2 = temp; } //assigns value of temp(original value of userVal1) to userVal2
The program prompts the user to enter two integers and then calls swapvalues() method by passing the integers by reference. The swapvalues() method modifies the passed parameters by swapping them. The method uses a temp variable to hold the original value of first integer variable and then assigns the value of second integer variable to first. For example if userVal1 = 1 and userVal2 =2. Then these swapping statements work as follows:
temp = userVal1;
temp = 1
userVal1 = userVal2;
userVal1 = 2
userVal2 = temp;
userVal2 = 1
Now because of these statements the values of userVal1 and userVal2 are swapped as:
userVal1 = 2
userVal2 = 1
Explanation:
Python program:
def swap_values(user_val1, user_val2): #method to swap two numbers
return user_val2,user_val1 #returns the swapped numbers
integer1 = int(input('Enter first integer :')) #prompts user to enter first number
integer2 = int(input('Enter second integer :')) #prompts user to enter second number
print("Numbers before swapping") #displays numbers before swapping
print(integer1,integer2)
print("Numbers after swapping") #displays numbers after swapping
integer1,integer2 = swap_values(integer1,integer2) #calls method passing integer1 and integer2 to swap their values
print(integer1,integer2) #displays the swapped numbers
The screenshot of programs and outputs is attached.
The program that swaps variables will return the reverse of the users input. The second integer input will be printed first followed by the first integer input.
The program that swaps the user integer input.def swap_variables(first_input, second_input):
return second_input, first_input
first_input = input("input the first integer: ")
second_input = input("input the second integer: ")
print(f"numbers before swapping are {first_input} and {second_input}")
print(f"numbers after swapping are {second_input} and {first_input}")
Code explanation
The code is written in python.
The first line of code we defined a function named "swap_variables" and it accept parameters as first_input and second_inputs.Then we returned the swapped items.The first_input is used to store the users first inputThe second_input is use to store the users second inputThen, we print the original valuesFinally, we print the swapped users inputlearn more on python variables here: https://brainly.com/question/14039335

Which of the following arguments are valid? Explain your reasoning
a) I have a student in my class who is getting an A. Therefore, John, a student in my class is getting an A
b) Every girl scout who sells at least 50 boxes of cookies will get a prize. Suzy, a girl scout, got a prize. Therefore Suzy sold 50 boxes of cookies.
Answer:
a) the Statement is Invalid
b) the Statement is Invalid
Explanation:
a)
lets Consider, s: student of my class
A(x): Getting an A
Let b: john
I have a student in my class who is getting ab A: Зs, A(s)
John need not be the student i.e b ≠ s could be true
Hence ¬A(b) could be true and the given statement is invalid
b)
Lets Consider G: girl scout
C: selling 50 boxes of cookies
P: getting prize
s: Suzy
Now every girl scout who sells at least 50 boxes of cookies will get a prize: ∀x ∈ G, C(x) -> P(x)
Suzy, a girl scout, got a prize: s ∈ G, P(s)
since P(s) is true, C(s) need not be true
Main Reason: false → true is also true
Therefore the Statement is Invalid
The argument that is valid is B. Every girl scout who sells at least 50 boxes of cookies will get a prize. Suzy, a girl scout, got a prize. Therefore Suzy sold 50 boxes of cookies.
What is a valid argument?It should be noted that a valid argument simply means the argument that's the conclusion can be derived from the premise given.
In this case, the argument that is valid is that every girl scout who sells at least 50 boxes of cookies will get a prize. Suzy, a girl scout, got a prize. Therefore Suzy sold 50 boxes of cookies.

Many languages distinguish between uppercase and lowercase letters in user-defined names. What are the pros and cons of this design decision?
Answer:
Explanation:
The reasons why a language would distinguish between uppercase and lowercase in its identifiers are:
(1) So that variable identifiers may look different than identifiers that are names for constants, such as the convention of using uppercase for constant names and using lowercase for variable names in C.
(2) So that the catenated words such as names can have their first letter distinguished, as in Total Words. The primary reason why a language would not distinguish between uppercase and lowercase in identifiers is it makes programs less readable, because words that look very similar are actually completely different, such as SUM and Sum.

The first phase of setting up an IPsec tunnel is called ___________
Answer:
Internet Key Exchange
Explanation:
The first phase, setting up an IPsec tunnel, is called IKE phase 1. There are two types of setting up an IPsec tunnel.
What is an IPsec tunnel?Phase 1 and Phase 2 of VPN discussions are separate stages. Phase 1's primary goal is to establish a safe, encrypted channel for Phase 2 negotiations between the two peers. When Phase 1 is successfully completed, the peers immediately begin Phase 2 negotiations.
When two dedicated routers are deployed in IPsec tunnel mode, each router serves as one end of a fictitious "tunnel" over a public network. In IPsec tunnel mode, in addition to the packet content, the original IP header containing the packet's final destination is also encrypted.
Therefore, the first phase, setting up an IPsec tunnel, is called IKE phase 1.

What additional features on your router would you implement if you were setting up a small wired and wireless network
Answer:
Explanation: The following features will be implemented:
1) Guest networks,
2) Networked attached storage,
3) MAC filtering
A guest Wi-Fi network is essentially a separate access point on your router. All of your home gadgets are connected to one point and joined as a network, and the guest network is a different point that provides access to the Internet, but not to your home network. As the name implies, it's for guests to connect to.
Network Attached Storage
is dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a local area network (LAN) access the shared storage via a standard Ethernet connection.
MAC address filtering allows you to define a list of devices and only allow those devices on your Wi-Fi network.

When troubleshooting Domain Name System (DNS) problems, which helpful feature do public servers usually support
Answer:
ICMP echo requests.
Explanation:
A Domain Name System (DNS) can be defined as a naming database in which internet domain names (website URLs) are stored and translated into their respective internet protocol (IP) address. This simply means that, DNS is used to connect uniform resource locator (URL) or web address with their internet protocol (IP) address.
When troubleshooting Domain Name System (DNS) problems, one helpful feature the public servers usually support is an ICMP echo requests.
ICMP is an acronym for Internet Control Message Protocol and it is a standard protocol for communicating network errors in the form of messages such as Time exceeded and Destination unreachable.
In Computer Networking, an echo reply and echo request are implemented with a command utility referred to as ping. When a user sends an echo request message with the ping program, a successful attempt will return an echo reply message.
Hence, when troubleshooting Domain Name System (DNS) problems, a user should ping a public server such as a Google DNS server with the IP address (8.8.8.8 or 8.8.4.4), Cloudfare with 1.1.1.1 or the common 4.2.2.2 DNS server. If successful, it means the name-server was resolved properly into an IP address and therefore, there's an active connection on the network.
Based on the information given, the helpful feature that public servers usually support is the ICMP echo requests.
It should be noted that a Domain Name System simply means a naming database where the internet domain names are stored and translated into their respective internet protocol address.
It should be noted that when troubleshooting Domain Name System problems, the helpful feature that public servers usually support is the ICMP echo requests.

Write a program that prints all the numbers from 0 to 6 except 3 and 6. Expected output: 0 1 2 4 5
for x in range(7):
if (x == 3 or x==6):
continue
print(x, end=' ')
print("\n")
Output:>> 0 1 2 4 5
Explanation:The code above has been written in Python. The following explains each line of the code.
Line 1: for x in range(7):
The built-in function range(7) generates integers between 0 and 7. 0 is included but not 7. i.e 0 - 6.
The for loop then iterates over the sequence of number being generated by the range() function. At each iteration, the value of x equals the number at that iteration. i.e
For the first iteration, x = 0
For the second iteration, x = 1
For the third iteration, x = 2 and so on up to x = 6 (since the last number, 7, is not included).
Line 2: if (x == 3 or x == 6):
This line checks for the value of x at each iteration. if the value of x is 3 or 6, then the next line, line 3 is executed.
Line 3: continue
The continue keyword is used to skip an iteration in a loop. In other words, when the continue statement is encountered in a loop, the loop skips to the next iteration without executing expressions that follow the continue statement in that iteration. In this case, the print(x, end=' ') in line 4 will not be executed when x is 3 or 6. That means 3 and 6 will not be printed.
Line 4: print(x, end=' ')
This line prints the value of x at each iteration(loop) and then followed by a single space. i.e 0 1 2 ... will be printed. Bear in mind that 3 and 6 will not be printed though.
Line 5: print("\n")
This line will be printed after the loop has finished execution. This line prints a new line character.
The program is an illustration of loops.
Loops are used to perform repetitive operations.
The program in Python, where comments are used to explain each line is as follows:
#This iterates from 0 to 6
for i in range(7):
#This checks if the current number is not 3 or 6
if not i==3 and not i == 6:
#If yes, the current number is printed

how do you think calculator of a computer works? describe the procedure.
plz answer quickly its urgent!!!
Explanation:
calculators work by processing information in binary form. We're used to thinking of numbers in our normal base-ten system, in which there are ten digits to work with: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The binary number system is a base-two system, which means there are only two digits to work with: 0 and 1. Thus, when you input numbers into a calculator, the integrated circuit converts those numbers to binary strings of 0s and 1s.
The integrated circuits then use those strings of 0s and 1s to turn transistors on and off with electricity to perform the desired calculations. Since there are only two options in a binary system (0 or 1), these can easily be represented by turning transistors on and off, since on and off easily represent the binary option
Once a calculation has been completed, the answer in binary form is then converted back to our normal base-ten system and displayed on the calculator's display screen.
