The best known multiple letter encryption cipher is the __________ , which treats digrams in the plaintext as single units and translates these units into ciphertext digrams
Answer:
Playfair Cipher.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
The best known multiple letter encryption cipher is the Playfair Cipher, which treats digrams in the plaintext as single units and translates these units into ciphertext digrams.
In the Playfair Cipher, a 5 × 5 matrix comprising of letters is developed using a keyword and then, the matrix is used to encrypt the plaintext as a pair i.e two letters at a time rather than as a single text.
Recently, your company's file server was the victim of a hacker attack. After researching the attack, you discover that multiple computers were used to implement the attack, which eventually caused the file server to overload. Which attack occurred
Answer:
Denial of Service attack
Explanation:
Denial of service is a type of attack on computer systems in which a particular system is targeted and flooded with traffic from multiple systems, thus causing an overload of the attacked system, and an eventual crash. The aim of the perpetrators of this attack is to prevent the rightful owners of the system from gaining access to it.
The above described attack is a Denial of service attack because;
1. the attack came from multiple computers
2. the attacked server experienced an overload most likely caused because it was overwhelmed with traffic.
Write a for loop with a range function that prints the following output. Name the target variable number. 0 1 2 3 4 5
Answer:
The program in Python is as follows:
for number in range(6):
print(number, end=' ')
Explanation:
From the program, the range is 0 to 5.
The following line iterates from 0 to 5 using "number" as its iterating variable
for number in range(6):
This prints each number in the range followed by a blank space
print(number, end=' ')
The for loop with a range function that prints the following output 0 1 2 3 4 5 is as follows:
for i in range(6):
print(i)
The code is expected to print the values 0 1 2 3 4 5.
A for loop is used to loop through the range values of 6. The range value of 6
are 0 1 2 3 4 and 5.
The range function is used as required to get the value.
Finally, we print the looped values
The code will output 0 1 2 3 4 5

Which term removes 7:10 from the dictionary
To remove an item from a dictionary in Python, you follow the syntax below:
[dictionary-name].pop(key)
In this case:
The dictionary name is info and the key is 7
So, the term that implements the syntax is: info.pop(7)
After the instruction info.pop(7) is executed, the content of the dictionary becomes: {3: 10.4:23, 11:31}

Ethernet ensures that _____ on a shared network never interfere with each other and become unreadable.
Answer:
Signals.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Ethernet ensures that signals on a shared network never interfere with each other and become unreadable through the use of encapsulation and standard encryption protocols.
In Computer Networking, encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).
The TCP/IP model comprises of four (4) layers;
1. Application layer: this is the fourth layer of the TCP/IP model. Here, the data unit is encapsulated into segments and sent to the transport layer.
2. Transport layer (layer 3): it receives the segment and encapsulates it into packets and sends to the internet layer.
3. Internet layer (layer 2): packets are encapsulated into frames.
4. Network layer (layer 1): frames are then converted into bits and sent across the network (LAN).
Hence, the data unit encapsulated inside a packet is known as segment, which is typically referred to as packet segmentation.
Additionally, these data, segments, packets, frames and bits transmitted across various layers are known as protocol data units (PDUs).
How do the interests of carriers differ from the interests of websites? What are the implications for websites from a value chain perspective?
Answer:
Explained below.
Explanation:
- The interest of the carriers has it's major focus on the process of getting funds from both individual customers and corporate entities that run the websites. However, the interest of websites’ has it's major focus on the process of generating funds in form of subscriptions or funds gotten from paid adverts from both individual customers and corporate entities.
- In terms of value chain perspectives; the websites experience far more pressure to keep fresh and exciting features and services on their platform while carriers don't experience that but only experience having to compete with innovations being done by their existing competitors to remain leaders in the field.
def find_max(nums: [int]) -> int:
'''
Finds the maximum value in the given list of integers,
or None if the list is empty
'''
largest = None
for num in nums:
if largest == None or num > largest:
largest = num
return largest
Rewrite the find_max function so that it uses recursion to work its way through the list instead of using a loop. Your rewritten function should accept the same kinds of inputs (i.e., a one-dimensional list of integers) and generate the same outputs. In your view, is this a problem that's well-suited to a recursive solution in Python.
Answer:
The program in recursion is:
def find_max(nums):
if len(nums) == 0:
return "None"
elif len(nums) == 1:
return nums[0]
else:
return max(nums[0],find_max(nums[1:]))
Explanation:
This line defines the function
def find_max(nums):
This checks if the list is empty.
if len(nums) == 0:
If yes, it returns "None"
return "None"
If the list has just one element
elif len(nums) == 1:
It returns the only element as the maximum
return nums[0]
If the list has numerous elemente
else:
The maximum is determined recursively
return max(nums[0],find_max(nums[1:]))
To the (b) part:
This program does not necessarily need to be done recursively because the max built-in function can be used to determine the maximum of the list in just one line of code and it is more efficient.

As a security measure, you implement time and date stamps in a payroll application program while transactions are being recorded. What is the role of this security measure
Answer:
Explanation:
The main role of this security measure is to maintain the integrity and validity of the recorded transactions. Implementing these timestamps and dates allows for transactions to be completely organized and easily found by simply searching for the time that the transaction took place. This also helps prevent anyone from making false transactions as they can be easily traced using these time stamps to make sure that they actually happened.
Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the average commercial rate, and also display the information for the highest and lowest rates found.
Answer:
In python:
file = open("rates.csv", "r")
ratecount = 0
ratesum = 0
mylist = []
rates = file.readlines()
for nums in rates:
num = nums.rstrip('\n')
mylist.append(int(num))
for i in num:
ratesum= ratesum + int(i)
ratecount = ratecount + 1
print("Maximum Rate: "+str(max(mylist)))
print("Minimum Rate: "+str(min(mylist)))
print("Average Rate: "+str(ratesum/ratecount))
Explanation:
This opens the csv file
file = open("rates.csv", "r")
This initializes the number of rates in the file
ratecount = 0
This initializes the sum of the rates
ratesum = 0
This initializes an empty list
mylist = []
This reads the rates into lines
rates = file.readlines()
This iterates through the rates (as a string)
for nums in rates:
This removes the newline character \n in the rates
num = nums.rstrip('\n')
This appends the rates (as an integer) to the empty list
mylist.append(int(num))
The following counts the rates in the file and also sum them up
for i in num:
ratesum= ratesum + int(i)
ratecount = ratecount + 1
This prints the maximum of the rates
print("Maximum Rate: "+str(max(mylist)))
This prints the minimum of the rates
print("Minimum Rate: "+str(min(mylist)))
This calculates and prints the average rate
print("Average Rate: "+str(ratesum/ratecount))
The __________ operator increases the value of the variable by 1 after the original value is used in the expression in which the variable appears.
Answer:
postincrement.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
The postincrement operator increases the value of the variable by 1 after the original value is used in the expression in which the variable appears.

Write a Java program that asks the user to enter an array of integers in the main method. The program will ask the user for the number of integer elements to be put in the array, and then ask the user for each element of the array. The program then calls a method named isSorted() that accepts an array of integers and returns true if the list is in sorted (increasing) order and false otherwise. For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2, 5, 3, 12, 10] respectively, the calls isSorted(arr1) and isSorted(arr2) should return true and false respectively. Assume the array has at least one integer element. A one-element array is considered to be sorted.
Answer:
The program is as follows:
import java.util.Scanner;
public class MyClass {
public static Boolean isSorted(int [] arr){
Boolean sorted = true;
for(int i = 0;i<arr.length;i++){
for(int j = i;j<arr.length;j++){
if(arr[i]>arr[j]){
sorted = false;
break;
}
}
}
return sorted;
}
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Length of array: ");
n = input.nextInt();
int[] arr = new int[n];
System.out.println("Enter array elements:");
for(int i = 0; i<n;i++){
arr[i] = input.nextInt();
}
Boolean chk = isSorted(arr);
System.out.print(chk);
}
}
Explanation:
The method begins here
This line defines a method named isSorted
public static Boolean isSorted(int [] arr){
This line declares a boolean variable and initializes it to true
Boolean sorted = true;
The next two iterations iterate through elements of the array
for(int i = 0;i<arr.length;i++){
for(int j = i;j<arr.length;j++){
This compares an array element with next elements (to the right)
if(arr[i]>arr[j]){
If the next element is smaller than the previous array element, then the array is not sorted
sorted = false; The boolean variable is updated to false
break; This breaks the loop
}
}
}
This returns true or false, depending on the order of the array
return sorted;
}
The main method begins here
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
This prompts user for length of array
System.out.print("Length of array: ");
This gets length of array from user
n = input.nextInt();
This declares an array
int[] arr = new int[n];
This prompts user for array elements
System.out.println("Enter array elements:");
The following iteration gets the array elements
for(int i = 0; i<n;i++){
arr[i] = input.nextInt();
}
This calls the isSorted array
Boolean chk = isSorted(arr);
This prints true or false, depending if the array is sorted or not
System.out.print(chk);
}

Answer:
The solution to this question can be defined as follows:
Explanation:
If we learn, they should use normal intel syntax in MASM assembly language when writing assembly codes. Consequently, its first operand was its venue, and another is the source as per this intellect syntax.
For instance. In mov eax ,var1
eax is a 32-bit data registry that would be the aim, that is copies to eax by the meaning of var1.
bx is a 16-bit base registry that has a var2 value.
bh is indeed a simple registry 8-bit component provided to the Var1 value.
It's not the Master Syntax, because they transfer the data contained from var2 to var1 explicitly instead of using the records. It's the best approach, when they move data, through the registers.
