Explanation:
Consider our authentication protocol 4.0, in which Alice authenticates herself to Bob, which we saw works well (i.e., we found no flaws in it.). Now suppose that at the same time that Alice authenticates herself to Bob, Bob must authenticate himself to Alice. Give a scenario by which Trudy, pretending to be Alice, can now authenticate herself to Bob as Alice.

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90 = < X o
B: 80 = < x < 90
C: 70 = < X < 80
D: 60 = < x < 70
E: X < 60
• Compute the average of each exam.
• Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character.
• Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the setprecision manipulator to format the output.
Ex: If the input of the program is:
StudentInfo.tsv
and the contents of StudentInfo.tsv are: 70 45 59
Barrett Edan 96 97 88
Bradshaw Reagan 73 94 80
Charlton Caius 88 61 36
Mayo Tyrese 90 86 45
the file report txt should contain
Barrett Edan 70 45 59 F
Baadha Boagan 9e 157 89 A
Charlton Caius 73 94 80 B
Mayo and Tyrese 58 61 36 D
Stern and Brenda 90 36 45 C
Average midterm 83.40, midterm2 76.60, final 61.60

Buddys machine shop has a kiosk computer located in the lobby for customers to use. The kiosk computer has recently been updated to Windows 10 from Windows 7 and is not part of a domain. The local computer policy created for Windows 7 has been applied to Windows 10. This policy severely restricts the use of the computer, so that customers can only use the web browser.
Occasionally, an administrator needs to sign in to the kiosk computer to perform maintenance and update software. However, this is awkward because the administrator needs to disable settings in local policy be performing any task. Then, when the tasks are complete, the administrator needs to re-enable the settings in the local policy. Explain how this system can be improved upon.

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. Nested lists The “*” operator List slices The “+=” operator A list filter A list operation that is legal but does the "wrong" thing, not what the programmer expects Provide the Python code and output for your program and all your examples.
Lists are used in Python to hold multiple values in one variable
(a) Nested list
A nested list is simply a list of list; i.e. a list that contains another list.
It is also called a 2 dimensional list.
An example is:
nested_list = [[ 1, 2, 3, 4] , [ 5, 6, 7]]
(b) The “*” operator
The "*" operator is used to calculate the product of numerical values.
An example is:
num1 = num2 * num3
List slices
This is used to get some parts of a list; it is done using the ":" sign
Take for instance, you want to get the elements from the 3rd to the 5th index of a list
An example is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
secondList = firstList[2:5]
The “+=” operator
This is used to add and assign values to variables
An example is:
num1 = 5
num2 = 3
num2 += num1
A list filter
This is used to return some elements of a list based on certain condition called filter.
An example that prints the even elements of a list is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
print(list(filter(lambda x: x % 2 == 0, firstList)))
A valid but wrong list operation
The following operation is to return a single list, but instead it returns as many lists as possible
def oneList(x, myList=[]):
myList.append(x)
print(myList)
oneList(3)
oneList(4)

Game Changer Technologies has four software teams. Each of them is developing four different examples of its new game app. Which software development methodology is used by the Game Changer teams
The software development methodology used by the Game Changer teams is called; Prototyping
We are given that;
- Game changer technologies has four software teams
- Each of the teams develops 4 different examples of the new game app.
Now, since each of them is developing four four different examples of its new game app, the method being used is called prototyping. This is because prototyping is referred to as the early approximation of the final system of a product whereby such a product is built, tested and rebuilt if required until an acceptable prototype is achieved.

that the mat will disintegrate
D.
that the mat will discolor and deteriorate
Answer:
That the mat will discolor and deteriorate
Explanation:
D
Yvonne will most likely worry that the mat will discolor and deteriorate. The correct option is D.
What is matting in photos?Matting is a decorative border that surrounds the artwork. It is typically built of mat board, a type of board designed specifically for this purpose. After cutting the mat board to size, one or more holes (entries) are cut in the mat board to act as windows for displaying art.
Matting is the technique of separating an image's foreground and background components. Typically, the photos are of a frame or a video file. It adds a decorative edge to the print and a mechanism for hanging the photo.
Matting involves using a front or window mat to separate the image from the frame's glass and to give an extra border around the photo.
Therefore, the correct option is D. that the mat will discolor and deteriorate.

Answer:
Operating systems have some code called an 'interrupt handler', which prioritises the interrupts and saves them in a queue. Buffers are used in computers as a temporary memory area, and they are essential in modern computers because hardware devices operate at much slower speeds than the processor.
Write a program that simulates applying a "boost" to a spaceship in a spaceship race game.
A spaceship makes progress by getting a "boost" value between 0 and 10. The boost value
is determined from generating a random number between 0 and 10. Assuming the starting
distance of the spaceship is 0, the program will output the boost value and the total
distance travelled by the spaceship after applying the boost. (Note: Two newlines are output
after the final output of the program).
When a random seed value of 2 is used, the output of the program will look like:
Boost: 6
Distance travelled: 6
Programming languages can be used to simulate several scenarios; in this case, the "boost"
The simulating program in C++ where comments are used to explain each line is as follows:
#include<iostream>
#include<cstdlib>
#include<ctime>
using namespace std;
int main() {
// This sets the seed to time(0)
srand(time(0));
// This generates a random number between 0 and 10, to represent the boost
int boost = rand()%10;
// This prints the required outputs
cout << "Boost: " << boost;
cout << "\nDistance travelled: " << boost;
return 0;

for item in data:
if item[0] == 'male':
males = males + 1
if item[___
]:
malesOnPhone = malesOnPhone + 1
Choices are 1, 2, 3. Answer is for if item[___]:
Three steps can be taken to construct a list of elements using a for loop: Make an empty list appear. Iterate through an iterable or set of elements. Add each component to the list's end.
What loop for sample member of the list data?An Array List can be looped through using an Iterator. If there are additional members in the Array List, the method hasNext() returns true; otherwise, it returns false. If there is no next element, the method next() raises the No Such Element Exception and returns the next element in the Array List.
FOR LOOPS and WHILE LOOPS are two popular types of loops. A For loop runs a variable number of times. LOOP TYPE — FOR LOOP When you know how many times you want to run an algorithm before stopping, you use for loops.
Therefore, Since indexation in lists begins at 0, we must compare item[0], which is “male,” with “male” in the if statement before iterating through males in the for loop.
