Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading.

Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern.

For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example:

Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext = "WKH FDW LV YLVLEOH DW PLGQLIJKW"

The keys to decrypt this message are the shift number and the direction. The shift value can be any integer from 0 - 25. The above example uses shift = 3 and the shift direction is right or direction = 'r'.

Complete the CipherTest class by adding a constructor to initialize a cipher item. The constructor should initialize the shift to 0, and the direction to 'r' for right shift. If the constructor is called with a shift value, and direction, the constructor should assign each instance attribute with the appropriate parameter value.

Complete the following TODO's: (1) create input for text, shift value, and direction (use lower( )) to keep l and r lower case (2) create a cipher item and use the constructor with the above input values (3) use control structures to call shifttoright() if direction is right and call shifttoleft if direction is left. Make sure you print out the return encrypted message inside the control structures.

We can create the encrypted text by using the ord ( ) function. This function will return an integer that represents the Unicode code point of the character. Character are represented by different values for upp/er and lower case so an 'a' returns the integer 97. By using the unicode value we can add and subtract our shift value represented by an integer.

The given program accepts as input a text string as our message to be encrypted, a shift value, and a direction of 'l' for left and 'r' for right. The program creates a cipher item using the input values. The program outputs the encrypted message based on the shift value and the direction provided.

Ex: If the input is text = "Cryptography is fun!", shift = 4, and direction = l.
The output is:

Explanation:

Boolean value can either be True or False.

Control statements check if a certain condition is met. If it is then they evaluate to be true then the necessary lines of code are executed. If it evaluates to be False, the lines of code that were suppose to be executed are skipped.

For example, if y is greater than zero, divide x by y

relative.

The coordinates for the section element need not be defined as long as its position is set to relative.

If the position is set as relative, then it will have no effect on the positioning attributes, it will consider as static position. If positioning is mentioned explicitly like top: 20px; then it will position 10 pixels down from where it is located. An ability for positional shifts is extremely helpful.

Two things happen when an element is set as relative, one is it introduces the ability to use z-index on that element, second is it limits the scope of absolutely positioned child elements.

numA = 2

numB = 3

if numA == 2 or numB == 2:

   print("yes")

elif numA == 2 and numB == 3:

   print("no")

numA = 2

This line of code declares the variable numA and gives it a value of 2

numB = 3

This line of code declares the variable numB and gives it a value of 3

if numA == 2 or numB == 2:

This part activate the next line of code only if the statement (numA == 2 or numB == 2) is True

   print("yes")

   This code prints out "yes" in the terminal.

elif numA == 2 and numB == 3:

This line of code is similar to the ifstatement above. The code below activates only if the statement (numA == 2 and numB == 3) is True and the previous ifstatement wasn't True.

Answer:1.) Analog

2.) Digital

3.) Pixels

4.) Local Area Network

5.) Bus

6.) Slots

Explanation:

The answers to the given questions are:

Analog Sound

Digital Sound

Pixels

Local Area Network (LAN)

Bus

Slots

Physical waves that travel through matter are referred to as analog sound waves.

These waves are continuous and represent the variations in air pressure caused by sound.

Analog sound is used in older forms of audio technology like vinyl records and cassette tapes.

Hence, Analog Sound are physical waves that travel through matter.

Electrical impulses represented as 0's and 1's are characteristic of digital sound.

In digital sound, sound signals are converted into binary code (0's and 1's) which can then be processed and transmitted by computers and other digital devices.

Hence, Digital Sound  are electrical impulses represented as 0’s and 1’s.

The images seen on a monitor or screen are made up of tiny dots called pixels.

Each pixel represents a single point of color or light, and when millions of pixels are combined, they create the images and videos that we see on digital displays.

Hence, the tiny dots that make up the images seen on a monitor called Pixels.

A Local Area Network (LAN) is a network that is confined to a small geographic area, such as within a building, a campus, or a specific group of interconnected buildings.

LANs are commonly used to connect computers and devices within a limited area.

So, Local Area Network is a network that is confined to a small area.

A bus is a subsystem in a computer that facilitates the transfer of data between different computer components (such as the CPU, memory, and peripherals) or between different computers in a network.

Buses can be thought of as communication pathways that enable the flow of information.

Hence, Bus is a subsystem that either transfers data between computer components or between computers.

Slots are openings in a computer's chassis or motherboard where printed circuit boards (also known as expansion cards) can be inserted. These expansion cards can add various capabilities to the computer, such as graphics processing, sound, network connectivity, and more.

Hence,  in a computer where printed circuit boards can be inserted to expand the computer’s capabilities called slots.
