For this part of the assignment, create a "program" using the standard naming convention and answer the following questions as comments. All the questions relate to the Mortgage payment program in Program #2. Please note that the questions ask for the type of error that occurs, not the specific error. For example, 25/0 causes a "ZeroDvisionError", which is the specific error, but the type of error is a run-time error. 1) If the user were to enter abc as the initial size of the mortgage, what type of error would occur? Why? 2) If the line of code that asks for the third input number was written as: mp= input ("Now, enter your planned monthly payment:) what type of error would occur? Why? 3) Given the sample run shown above (with a maximum monthly payment of 666.67), if the planned monthly payment entered is the same (666.67), what would happen and why? 4) If the line of code to calculate the interest payments for a year was written as: Interest_payment = loan / (interest_rate/100) what type of error would occur? Why?
Using the standard naming convention, the answer the following questions as comments are:
1) The type of error that would occur if the user were to enter abc as the initial size of the mortgage is a ValueError. This is because the input function expects a numeric input and will raise a ValueError if it receives a non-numeric input.
2) If the line of code that asks for the third input number was written as: mp= input ("Now, enter your planned monthly payment:)
The type of error that would occur is a SyntaxError.
This is because there is a missing closing quotation mark at the end of the prompt string.
3) Given the sample run shown above (with a maximum monthly payment of 666.67), if the planned monthly payment entered is the same (666.67), the program would output "Congratulations! You can pay off your loan in a year!"
This is because the planned monthly payment is equal to the maximum monthly payment, which means the loan can be paid off in exactly one year.
4) If the line of code to calculate the interest payments for a year was written as:
Interest_payment = loan / (interest_rate/100) the type of error that would occur is a ZeroDivisionError.
This is because the interest_rate is divided by 100, and if the interest_rate is 0, this would result in a division by zero error.

Which one of the following would be the result of 1 's complement addition of −65 to the binary number 11010011 (already in 8-bit 1's complement)? 10010010 10010011 00010011 10101100 Which one of the following would be the result of 2 's complement addition of −73 to the binary number 11001010 (already in 8 -bit 1 's complement)? 11011011 10101011 1111111 10000001
The result of 1's complement addition of −65 to the binary number 11010011 is 10010010.
The result of 2's complement addition of −73 to the binary number 11001010 is 10000001.
In the 1's complement addition, the addition is performed in the same way as the normal binary addition with the only difference that the end result is complemented to make it a 1's complement. In order to add the number -65 to 11010011, we must first represent -65 in 8-bit 1's complement form.
For this, we will convert 65 into binary and complement it to get its 1's complement. 65 = 010000012
Now, we can represent -65 in 8-bit 1's complement form as 10111111 (-ve sign in front indicates the negative value).
Now, adding the 1's complement of -65 to 11010011: 11010011 + 10111111 __________ 1 10010010
Hence, the result of 1's complement addition of −65 to the binary number 11010011 is 10010010.
We can perform the 2's complement addition of -73 to 11001010 in the following way:
The 2's complement of -73 can be calculated by subtracting it from 2^8. 2^8 = 256-73 = 183
Hence, 2's complement of -73 is 10110111.
In 2's complement addition, we add the numbers as if they were normal binary numbers and discard any overflow beyond 8 bits. 11001010 + 10110111 = 1 01100001
As we see here, there is overflow beyond 8 bits. Hence, we discard the overflow and the result of 2's complement addition of −73 to the binary number 11001010 is 10000001. Thus, the correct option is 10000001.

The Hit the Target Game
In this section, we’re going to look at a Python program that uses turtle graphics to play
a simple game. When the program runs, it displays the graphics screen shown
in Figure 3-16. The small square that is drawn in the upper-right area of the window is
the target. The object of the game is to launch the turtle like a projectile so it hits the
target. You do this by entering an angle, and a force value in the Shell window. The
program then sets the turtle’s heading to the specified angle, and it uses the specified
force value in a simple formula to calculate the distance that the turtle will travel. The
greater the force value, the further the turtle will move. If the turtle stops inside the
square, it has hit the target.
Complete the program in 3-19 and answer the following questions
1. 3.22 How do you get the turtle’s X and Y. coordinates?
2. 3.23 How would you determine whether the turtle’s pen is up?

How does the TestCard class in Python utilize unit testing to ensure the correct functionality of card deck operations such as initialization and drawing the top card, and how can user-specified attributes be implemented?The TestCard class is designed to perform unit tests on the functionality of a card deck. Here are the key aspects of the class:
1. Initialization: The initialization test ensures that a deck is created with one copy of each possible card, using default values for numbers, shapes, colors, and shadings. The cards are stored in a list, with the last card being 3 solid purple ovals.
2. User-Specified Attributes: The class allows users to specify their own numbers, shapes, colors, and shadings if desired. The implementation should utilize the length magic method, `len()`, to handle these user-specified attributes.
3. `draw_top()`: This method draws and reveals (removes and returns) the top card from the deck. Since cards are stored in a list, the top card is the last item in the list. If an attempt is made to draw from an empty deck, an `AttributeError` should be raised.
To ensure the correctness of the TestCard class, unit tests should be implemented for each functionality using the `unittest` module. The tests should be accompanied by appropriate docstrings for better code readability and understanding.

Using JSP, Java Servlets and JDBC,
Develop an application for course registration for Academic year 2022-2023.
You need to provide the registration page with Reg. Number, Name and List of courses ( 10 Courses) along with its credits(2/3/4). You need validate that the student has taken minimum credits (16) and not exceeded the maximum credits (26). Once the student satisfies the minimum and maximum credits, you need to confirm the registration and update the details in the database. Finally, generate the course registration report ( Reg. Number, Name, Number of courses, total credits).
Develop a course registration application using JSP, Servlets, and JDBC to validate credits and update the database.
To develop an application for course registration using JSP, Java Servlets, and JDBC, follow the steps outlined below.
Create a registration page (registration.jsp) with input fields for the registration number, name, and a list of courses. The list of courses should include checkboxes or a multi-select dropdown menu for the student to choose from the available courses for the academic year 2022-2023. Each course should also display its corresponding credits (2/3/4).
In the servlet (RegistrationServlet.java) associated with the registration page, validate the student's course selection. Calculate the total credits by summing up the credits of the selected courses. Check if the total credits satisfy the minimum requirement of 16 and do not exceed the maximum limit of 26.
If the credit validation fails, redirect the user back to the registration page with an error message indicating the issue (e.g., insufficient credits or exceeding maximum credits). Display the previously entered information, allowing the user to make necessary adjustments.
If the credit validation passes, update the student's details in the database. You can use JDBC to connect to the database and execute SQL queries or use an ORM framework like Hibernate for data persistence.
Generate a course registration report (report.jsp) that displays the student's registration details, including the registration number, name, the number of courses selected, and the total credits.
In the servlet associated with the report page (ReportServlet.java), retrieve the student's details from the database using their registration number. Pass the retrieved data to the report.jsp page for rendering.
In report.jsp, display the student's registration information using HTML and JSP tags.
By following this approach, you can create a course registration application that allows students to select courses, validates their credit selection, updates the details in the database, and generates a registration report. Make sure to handle exceptions, use appropriate data validation techniques, and follow best practices for secure database interactions to ensure the application's reliability and security.

Your function should return True (Python's built-in truth object) if the number is contained anywhere within the range - including the endpoints. Otherwise, your function should return False (Python's built-in untruth object).
Author your solution using the test data provided in the code-cell below.
Writing a Python function:
def check_number_in_range(start, end, number):
return number in range(start, end+1)
The provided Python function `check_number_in_range` takes three arguments: `start`, `end`, and `number`. It uses the built-in `range()` function in Python to generate a sequence of numbers starting from `start` up to `end+1` (inclusive). The function then checks if the `number` is present within this range by using the `in` keyword to test for membership.
If the `number` is contained anywhere within the range (including the endpoints), the function will return `True`, which is Python's built-in truth object. Otherwise, if the `number` is not within the range, the function will return `False`, which is Python's built-in untruth object.
The `range()` function creates a sequence of numbers based on the provided `start` and `end+1` values. The `+1` is added to the `end` argument to include the upper endpoint of the range, as the `range()` function generates a sequence that stops before the specified end value.
By using the `in` keyword, we can efficiently check if the `number` is present within the generated range, and the function returns the appropriate result based on the presence or absence of the number in the range.

Using PROC IMPORT read in the provided SPSS data file (Assignment 1 Data.sav). (In case you are interested, this is an NHANES (National Health And Nutritional Examination Survey) data set with variables specific to taste and smell assessment adapted from the NIH Toolbox Project and also included variables on cigarette usage). a. After importing the data, examine the log and note anything out of the ordinary. Use the information in the Note to get more details. b. Using PROC CONTENTS, tell me how many observations are in the data set and how any variables are in the data set. c. Using a new DATA step, keep only the following variables: SEQN, SDDSRVYR, and RIDAGEYR. d. Using a new DATA step, keep only observations where SDDSRVYR =8. How many observations does the data set have now? e. Use PROC MEANS (Look in the SAS Help Documents for syntax and options) to calculate the number of observations, the number of observations with missing values, the mean, the standard deviation, the median, the minimum and the maximum value of the RIDAGEYR variable using two decimal places.
By executing these steps, the dataset will be imported, and the log file will be generated, containing information about the successful import and the dataset's contents.
a) Importing Data and Examining the Log:
To import the data file and examine the log for any anomalies, use the following code:
proc import datafile='C:\Users\Ram\Desktop\Assignment 1 Data.sav' out=mydata dbms=sav replace;
run;
proc printto log='C:\Users\Ram\Desktop\Assignment 1 Log.txt';
run;
proc import datafile='C:\Users\Ram\Desktop\Assignment 1 Data.sav' out=mydata dbms=sav replace;
run;
proc printto;
run;
By executing these steps, the dataset will be imported, and the log file will be generated, containing information about the successful import and the dataset's contents.
b) Checking Number of Observations and Variables:
To determine the number of observations and variables in the dataset, use PROC CONTENTS as follows:
proc contents data=mydata;
run;
proc sql;
select count(*) as obs_count from mydata;
select count(*) as var_count from dictionary.columns where libname = 'WORK' and memname = 'MYDATA';
quit;
Executing these codes will provide details about the dataset, including the count of observations and variables.
c) Keeping Selected Variables:
To retain only specific variables (SEQN, SDDSRVYR, and RIDAGEYR) in a new DATA step, use the following code:
data mydata_new;
set mydata(keep=SEQN SDDSRVYR RIDAGEYR);
run;
This code will create a new dataset called "mydata_new" containing only the desired variables.
d) Keeping Observations with SDDSRVYR=8:
To filter the dataset and keep only the observations where SDDSRVYR=8, use the following code:
data mydata_filtered;
set mydata(where=(SDDSRVYR=8));
run;
This code will create a new dataset called "mydata_filtered" with only the observations where SDDSRVYR equals 8. To determine the number of observations in the filtered dataset, use PROC SQL as shown in the next step.
e) Calculating Statistics using PROC MEANS:
To calculate descriptive statistics for the RIDAGEYR variable, including the number of observations, number of missing values, mean, standard deviation, median, minimum, and maximum values (rounded to two decimal places), use the following code:
proc means data=mydata_missing n nmiss mean std median min max;
var RIDAGEYR;
format RIDAGEYR 6.2; /* Apply two decimal places formatting */
run;
Executing these steps will generate a summary of the statistics for the RIDAGEYR variable, considering missing values and rounded to two decimal places.

Write a method called replaceAll. The method takes in one item as a parameter and modifies the current Trio so that it holds three of that item.
The replaceAll method modifies the current Trio object by replacing its contents with three instances of a specified item.
The replaceAll method is designed to modify the existing Trio object by replacing its current contents with three instances of a given item. This method takes in one parameter, which represents the item that will be used to replace the Trio's contents. By calling the replaceAll method on a Trio object and passing the desired item as an argument, the Trio will be updated to hold three instances of that item.
The implementation of the replaceAll method involves replacing the contents of the Trio with the specified item. This can be achieved by assigning the item to each of the three elements in the Trio. For example, if the Trio initially contains items A, B, and C, and the replaceAll method is called with item X, the resulting Trio will hold three instances of X.
The replaceAll method provides a convenient way to update the Trio's contents in a uniform manner. It ensures that the Trio consistently holds three instances of the specified item, regardless of its previous contents. This can be useful in scenarios where the Trio needs to be reset or where a specific item needs to be replicated throughout the Trio.

Perform the following operation using PHP and XML, 1. Registration page: Store the registration data in a XML file using appropriate user defined tags. 2. Login page: Verify and authenticate a user by fetching the appropriate data (username and password) from the XML file. 3. Home page (specific to your chosen application): Store the details of your home page in an XML file and fetch them to display in the home page embedded into their appropriate HTML \& CSS styles.
1. Registration page: In the registration page, the user will fill out a form that will store the registration data in an XML file using appropriate user-defined tags. To do this, we'll use the following code snippet to generate an XML file using PHP:
$dom = new DOMDocument();
$dom->encoding = 'utf-8';
$dom->xmlVersion = '1.0';
$dom->formatOutput = true;
$xml_file_name = 'registration_data.xml';
$root = $dom->createElement('registration_data');
$registration_data_node = $dom->appendChild($root);
$name_node = $dom->createElement('name', $name);
$registration_data_node->appendChild($name_node);
$email_node = $dom->createElement('email', $email);
$registration_data_node->appendChild($email_node);
$password_node = $dom->createElement('password', $password);
$registration_data_node->appendChild($password_node);
$dom->save($xml_file_name);
The above code will create an XML file with a root element called registration_data and three child elements, namely name, email, and password. The XML file will be saved to the local server with the name registration_data.xml.
2. Login page: In the login page, the user will enter their username and password, which will be verified and authenticated by fetching the appropriate data (username and password) from the XML file. To do this, we'll use the following code snippet to read data from an XML file using PHP:
$xml_file = 'registration_data.xml';
if(file_exists($xml_file)){
$xml = simplexml_load_file($xml_file);
if($xml){
foreach($xml->registration_data as $registration_data){
if($registration_data->name == $name && $registration_data->password == $password){
// authentication successful
}
}
}
}
The above code will read the registration_data.xml file and compare the entered name and password with the stored data. If the data matches, the authentication will be successful.
3. Home page: In the home page, the details of the page will be stored in an XML file and fetched to display in the home page embedded into their appropriate HTML & CSS styles. To do this, we'll use the following code snippet to generate an XML file using PHP:
$dom = new DOMDocument();
$dom->encoding = 'utf-8';
$dom->xmlVersion = '1.0';
$dom->formatOutput = true;
$xml_file_name = 'home_data.xml';
$root = $dom->createElement('home_data');
$home_data_node = $dom->appendChild($root);
$title_node = $dom->createElement('title', $title);
$home_data_node->appendChild($title_node);
$description_node = $dom->createElement('description', $description);
$home_data_node->appendChild($description_node);
$image_node = $dom->createElement('image', $image);
$home_data_node->appendChild($image_node);
$dom->save($xml_file_name);
The above code will create an XML file with a root element called home_data and three child elements, namely title, description, and image. The XML file will be saved to the local server with the name home_data.xml. Finally, we'll use PHP to fetch the data from the XML file and display it on the home page embedded into their appropriate HTML & CSS styles.

The program creates four identical arrays and a linked list of 5000 elements, assigns random values to each element, and applies bubble sort, selection sort, insertion sort, quick sort to the arrays, and merge sort to the linked list. It then outputs the number of element comparisons and swaps made by each sorting algorithm.
The program begins by creating four identical arrays and a linked list, all containing 5000 elements. Random values are assigned to each element to create unsorted data. The sorting algorithms are then applied to each data structure, and the number of element comparisons and swaps are recorded for each algorithm.
The three O(n^2) algorithms - bubble sort, selection sort, and insertion sort - are compared based on their performance in handling this dataset. Bubble sort repeatedly compares adjacent elements and swaps them if they are in the wrong order, resulting in many comparisons and swaps. Selection sort performs fewer swaps than bubble sort but still requires many comparisons. Insertion sort, on the other hand, performs relatively better as it reduces the number of comparisons and swaps by inserting elements into their proper positions.
The two O(log n) algorithms - quick sort and merge sort - are compared separately as well. Quick sort, a divide-and-conquer algorithm, shows better performance with fewer comparisons and swaps. Merge sort, while more efficient in general, is designed for linked lists, and in this case, we only measure the number of comparisons in the output.

Study the scenario and complete the question(s) that follow: In most computer security contexts, user authentication is the fundamental building block and the primary line of defence. User authentication is the basis for most types of access control and for user accountability. The process of verifying an identity claimed by or for a system entity. An authentication process consists of two steps: - Identification step: Presenting an identifier to the security system. (Identifiers should be assigned carefully, because authenticated identities are the basis for other security services, such as access control service.) - Verification step: Presenting or generating authentication information that corroborates the binding between the entity and the identifier. 2.1 Discuss why passwordless authentication are now preferred more than password authentication although password authentication is still widely used (5 Marks) 2.2 As an operating system specialist why would you advise people to use both federated login and single sign-on. 5 Marks) 2.3 Given that sessions hold users' authenticated state, the fact of compromising the session management process may lead to wrong users to bypass the authentication process or even impersonate as other user. Propose some guidelines to consider when implementing the session management process. (5 Marks) 2.4 When creating a password, some applications do not allow password such as 1111 aaaaa, abcd. Why do you think this practice is important
2.1 Password less authentication is now preferred more than password authentication due to various reasons. Password authentication requires users to create and remember complex passwords, which is a difficult and time-consuming process.
If users create an easy-to-guess password, the security risk becomes very high, while an overly complicated password is difficult to remember. Hackers also use a number of techniques to hack passwords, such as brute force attacks, dictionary attacks, and phishing attacks. In addition, people also reuse their passwords for multiple accounts, making it easier for hackers to access those accounts. Password less authentication methods, such as biometrics or a physical security key, eliminate these problems.
2.2 As an operating system specialist, I would advise people to use both federated login and single sign-on. Federated login allows users to use the same credentials to access multiple applications or services. This eliminates the need for users to remember multiple passwords for different services. Single sign-on (SSO) is also a way to eliminate the need to remember multiple passwords. With SSO, users only need to sign in once to access multiple applications or services. It provides a more streamlined authentication experience for users. Together, these two methods offer a secure and user-friendly authentication experience.
2.3 When implementing the session management process, some guidelines that should be considered are:
Limit the session time: Sessions should not remain open for a long time, as this would allow hackers to use them. After a certain time, the session should expire.
Avoid session fixation: Session fixation is a technique used by hackers to gain access to user accounts. Developers should ensure that session IDs are not sent through URLs and the session ID is regenerated each time the user logs in.
Use HTTPS: To secure data in transit, use HTTPS. It ensures that data sent between the server and the client is encrypted to prevent interception.
Avoid session hijacking: Developers should use secure coding practices to prevent session hijacking attacks.

The C/C++ statement that dynamically allocates memory for a singly linked list is option c: singlyLinkedList * sll = new singlyLinkedList.
In C/C++, the new keyword is used to dynamically allocate memory for objects. In this case, new singlyLinkedList dynamically allocates memory for a singly linked list object and returns a pointer to the allocated memory. The pointer sll is then assigned to this memory location.
By using the new operator, memory is allocated on the heap, allowing the program to dynamically manage the memory for the linked list. This is important for cases where the size of the linked list may vary during runtime or when the linked list needs to persist beyond the scope of the current function.
The other options (a, b, and d) either involve assignment or declaration without dynamic memory allocation, which does not fulfill the requirement of dynamically allocating memory for a singly linked list.

Assume we have a link with a rate of R kbps. Also suppose that each user alternates between periods of activity, when a user generates data at a constant rate of Kkbps, and periods of inactivity, when a user generates no data. Suppose further that a user is active only p percent of the time. (a) How many users can use this link using circuit switching? (b) Approximately how many users can use this link using packet switching if we allow a 1 percent probability of link overload? Hint: Use Chebyshev's inequality: Let X be a random variable with finite expected value μ and finite non-zero variance σ2. Then for any real number k>0, Pr(∣X−μ∣≥kσ)≤k21
(a) The maximum number of users that can use this link using circuit switching is given by R/K.
(b) Approximately, the number of users that can use this link using packet switching can be determined by calculating the link capacity and considering a 1 percent probability of link overload. This involves utilizing Chebyshev's inequality to estimate the number of users that can be supported.
The main answer is that the maximum number of users that can use this link using circuit switching is R/K. This means that the link capacity, R, divided by the rate at which each user generates data, K, gives us the maximum number of users that can be accommodated simultaneously using circuit switching.
Circuit switching is a technique where a dedicated communication path is established between the sender and the receiver for the entire duration of the communication. In this scenario, each user has alternating periods of activity and inactivity. During the active periods, a user generates data at a constant rate of K kbps. However, during the inactive periods, no data is generated. Given that a user is active only p percent of the time, the effective data rate for each user becomes p * K kbps.
To determine the maximum number of users that can be supported using circuit switching, we divide the link capacity, R kbps, by the effective data rate per user, p * K kbps. This yields the formula R/K. This calculation assumes that all users are active simultaneously, which may not be the case in practice.
For packet switching, the number of users that can be accommodated needs to consider the probability of link overload. To estimate this, we can use Chebyshev's inequality. Chebyshev's inequality states that for any random variable with a finite expected value and finite non-zero variance, the probability that the random variable deviates from its expected value by more than k standard deviations is at most 1/k^2.
By applying Chebyshev's inequality, we can determine the number of standard deviations, k, such that the probability of the link overload is within the acceptable limit of 1 percent. Using the formula Pr(|X - μ| ≥ kσ) ≤ k^2, where X represents the number of users, μ represents the expected value (mean), and σ represents the standard deviation, we can solve for k. Once we have the value of k, we can divide the link capacity, R, by the rate at which each user generates data, K, to obtain the approximate number of users that can be supported using packet switching.
