Creating a Shell Script
You will use command line arguments for the x and y values.
Be sure you follow the directions exactly.
Create a shell script named arithmetic_2.sh using Nano (or the GUI text editor if you prefer).
The script needs to perform the following pseudo code in the order shown:
Check to see if the user entered two numbers on the command line following the script name. If not, display an error message and exit, otherwise continue on.
Assign the first argument to a variable named x.
Assign the second argument to a variable named y.
Display the two values.
Divide y by x and display the result.
Save the file, and test it in the terminal. (What must you do before you can run it?)
When you’re satisfied that it works, upload it to Canvas.
If the user fails to supply the two values as arguments on the command line, prompt the user to enter them like you did in the first arithmetic exercise.
Do the above, but if the user gives you only one value as a command line argument, use it for the first one (x), and ask for the second one.
NOTE: Some of you may already know that doing simple division in a shell script usually results in whole number (integer) results. That's OK for the purpose of the exercise, which is to use command line arguments. Dividing by zero is something we wish to prevent, so check the input for x.

Copy code

Rtotal = 6 ohms + 5 ohms + 8 ohms

Rtotal = 19 ohms

To ensure message confidentiality, Alice and Bob should use a secure encryption algorithm, such as AES (Advanced Encryption Standard) or RSA (Rivest-Shamir-Adleman), to encrypt the message. This will ensure that the message cannot be read by anyone else except Alice and Bob.

To ensure non-repudiation, Alice and Bob should use digital signatures. Digital signatures are a form of authentication that ensures data integrity and non-repudiation. Digital signatures are created using cryptographic algorithms and are used to authenticate the sender of the message.

To ensure message integrity, Alice and Bob should use a secure hash encryption algorithm, such as SHA-256, to create a message digest of the message. This will ensure that the message has not been modified in any way and is intact.

The secret key can be securely shared between Alice and Bob using a key exchange protocol, such as Diffie-Hellman. This protocol allows Alice and Bob to securely exchange a key over an insecure channel without any third-party intervention.

Eve could launch a man-in-the-middle attack on the crypto system used by Alice and Bob. In this attack, Eve intercepts the communication between Alice and Bob and then relays modified versions of the messages between them. This allows Eve to gain access to the secure key without either Alice or Bob being aware of it. Eve could also launch a replay attack. In this attack, Eve intercepts and records the messages exchanged between Alice and Bob and then sends the same messages again to gain access to the secure key.

Robyn should access Outlook options from the Home tab. In the Home tab, she can find the option to customize the Quick Access toolbar, which will allow her to add the desired command if it is not available in the options under the More button. This can typically be done by right-clicking on the command in the ribbon and selecting "Add to Quick Access Toolbar."

In Microsoft Outlook, the Quick Access toolbar is a customizable toolbar that provides quick access to frequently used commands. The Quick Access toolbar is located above the ribbon, and by default, it includes commands such as Save, Undo, and Redo. However, if a user wants to add a command that is not available in the options under the More button for the Quick Access toolbar, they can do so by customizing the Quick Access toolbar.

To customize the Quick Access toolbar in Outlook, follow these steps:

Open Outlook and click on the "File" tab in the ribbon to access the Backstage view.

In the Backstage view, click on "Options." This will open the Outlook Options dialog box.

In the Outlook Options dialog box, select "Quick Access Toolbar" from the left-side menu.

In the Quick Access Toolbar section, you will see two options: "For all documents (default)" and "For <current document type>." Select the appropriate option depending on whether you want the command to be available in all Outlook documents or only in the current document type.

Click on the "Choose commands from" drop-down list and select the category that contains the command you want to add.

Scroll through the list of available commands, locate the desired command, and click on it to select it.

Click on the "Add" button to add the command to the Quick Access toolbar.

Repeat steps 5 to 7 for any additional commands you want to add.

When you have added all the desired commands, click on "OK" to close the Outlook Options dialog box.

After following these steps, the newly added command should now appear in the Quick Access toolbar, providing quick access to the desired functionality.

Answer:

Both technicians are correct! A push-button switch is a type of switch that is activated by pressing a button. It can be either momentary or maintained, which means it stays in the "on" or "off" position when the button is released.

Explanation:

A pressure switch is a special type of push-button switch that operates based on pressure, as Technician B stated. The switch stays in one position until a certain pressure is applied to the button, at which point it switches to the opposite position. This makes it ideal for applications where a switch needs to be activated by a physical force, such as when a certain pressure is reached in a fluid system.

So, both technicians have correctly described different aspects of push-button switches.

The two terms that are associated with digital publications and not print publications are "Pixel" and "RGB value".

A pixel is the smallest unit of a digital image, and it's used to measure the resolution of an image on a screen or digital device. In print publications, images are measured in DPI (dots per inch) instead of pixels.

RGB (Red, Green, Blue) is a color model used to display images on digital screens. Each color is represented by a numerical value between 0 and 255, and these values are combined to create a wide range of colors. In print publications, the color model used is typically CMYK (Cyan, Magenta, Yellow, Black), which is optimized for printing on paper.

   // Sort the numbers in ascending order

  int numbers[] = {a, b, c};

   sort(numbers, numbers + 3);

   cout << "Numbers in ascending order: " << numbers[0] << " " << numbers[1] << " " << numbers[2] << endl;

   // Sort the numbers in descending order

   sort(numbers, numbers + 3, greater<int>());

   cout << "Numbers in descending order: " << numbers[0] << " " << numbers[1] << " " << numbers[2] << endl;

   // Calculate the sum of the smallest and largest numbers

  int min = numbers[0];

   int max = numbers[2];

   int sum = min + max;

   cout << "Sum of Min and Max: " << sum << end

This program uses the sort function from the algorithm library to sort the array of numbers.

The sort function can sort the numbers in ascending order by default, and you can pass a custom comparison function (in this case, greater<int>) to sort the numbers in descending order.
