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.

for x in range(7):

   if (x == 3 or x==6):

       continue

   print(x, end=' ')

print("\n")

>> 0 1 2 4 5

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

       print(i,end=" ")

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.

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.

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.

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.

Answer:

c

Explanation:

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.

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}")

Explanation:

The program is well explained in the comments mentioned with each line of program

The program creates a GUI translator application using tkinter standard GUI library. In class Spanish2English first the main window is created which is the root widget. Next this main window is organized into three frames top, middle and bottom. A label is placed in the top frame which displays the text "Select a Spanish word to translate". Next, three buttons are created, for each Spanish word. The first button displays the Spanish word 'uno', second button displays the Spanish word 'dos' and third button displays the Spanish word 'tres'. Next, the two labels are created, one label is to display the text: "English translation: " and the other label is to display the English translation of the Spanish words in each button. In the last, three methods, word1, word2 and word3 are used to set the value of the translation object.

The program along with its output is attached.

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.
