Users with the right to read files in the folder have which of the following? Select all that apply.
a) Read/write rights
b) Owner rights
c) Reader rights
Users with the right to read files in the folder have "reader rights" which is "c".
Explanation: In computer systems, there are different types of user rights such as read, write, modify, delete, and execute. Read rights refer to the ability to view the content of a file or a folder. This means that users who have been granted read rights can open and view the content of the file but can't edit or delete it.
Only users who have been granted read/write or owner rights have the ability to modify, delete or add new content to the file or folder.
Therefore, option a) "read/write rights" and b) "owner rights" do not apply to the users who have been granted the right to read files in the folder.

Question 1: Process & Control
(a) List and explain the steps involved in building a mathematic
model. (10 Marks)
(b) Explain the difference between a static process model and a
dynamic process mod
(a) Building a mathematical model involves several steps, including problem formulation, data collection, model selection, parameter estimation, model validation, and model implementation. Each step contributes to developing a mathematical representation of a real-world system or phenomenon.
(b) The main difference between a static process model and a dynamic process model lies in the treatment of time. A static process model describes the system at a particular point in time and does not consider the time evolution of the variables. In contrast, a dynamic process model incorporates the temporal aspect, capturing how the system changes over time by modeling the dynamic behavior of the variables.
(a) The steps involved in building a mathematical model are as follows:
Problem formulation: Clearly define the problem to be modeled and the objectives to be achieved.
Data collection: Gather relevant data about the system or phenomenon being modeled. This may involve experiments, surveys, or literature review.
Model selection: Choose an appropriate mathematical representation that best captures the essential features of the system. This could involve selecting equations, statistical models, or system dynamics approaches.
Parameter estimation: Determine the values of the parameters in the mathematical model based on the available data. This may involve statistical estimation techniques or calibration processes.
Model validation: Assess the accuracy and reliability of the model by comparing its predictions with independent data or real-world observations.
Model implementation: Implement the mathematical model using appropriate software or programming languages to obtain useful outputs or predictions.
(b) A static process model describes a system or phenomenon at a specific moment in time. It does not consider the time evolution of variables but focuses on capturing the static relationships between inputs and outputs. Static models are suitable for situations where the system does not change significantly over time or where the temporal aspect is not of interest.
On the other hand, a dynamic process model incorporates the temporal aspect and captures how the system changes over time. It represents the time-dependent behavior of variables and accounts for the dynamics, such as the rate of change and interdependencies between variables. Dynamic models are suitable for systems that exhibit significant changes or where understanding the time evolution is essential, such as in predicting future behavior or simulating system responses to different inputs.
In summary, the choice between a static or dynamic process model depends on the nature of the system being modeled and the specific objectives of the analysis.

Assume you are given the following code and you are asked to extend it to support additional 2 and 3 -dimensional shapes. 1. What would you say is wrong with this design approach? 2. How would you fix
The main problem with this design approach is that it violates the principle of open-closed principle and does not adhere to the principles of object-oriented programming. To fix this, we can apply the concept of inheritance and create a base Shape class, from which the 2D and 3D shapes can be derived.
The given design approach lacks extensibility and maintainability. It directly modifies the existing code by adding separate logic for each new shape, which violates the open-closed principle. This principle states that software entities (classes, modules, functions, etc.) should be open for extension but closed for modification.
By directly modifying the existing code, we make it difficult to add new shapes in the future without making changes to the existing code.
To address this issue, we can introduce a base Shape class that defines common properties and behaviors shared by all shapes. This base class can have methods like `calculateArea()` and `calculateVolume()` that are specific to 2D and 3D shapes respectively.
We can then create separate classes for each shape (e.g., Square, Circle, Sphere, Cube) that inherit from the Shape class and provide their own implementation of the `calculateArea()` and `calculateVolume()` methods.
By using inheritance, we achieve a more modular and extensible design. We can easily add new shapes by creating a new class that inherits from the Shape class, without modifying the existing code. This approach adheres to the principles of object-oriented programming, such as encapsulation, inheritance, and polymorphism.

Problem Description:
Create a program that functions as a simple Boolean calculator for 32-bit integers. It should display a menu that asks the user to make a selection from the following list:
X AND Y
X OR Y
NOT X
X XOR Y
Exit Program
When the user makes a choice, call the corresponding procedure, which is one of the following four:
AND_op: Prompt the user for two hexadecimal integers. AND them together and display the result in hexadecimal
OR_op: Prompt the user for two hexadecimal integers. OR them together and display the result in hexadecimal.
NOT_op: Prompt the user for a hexadecimal integer. NOT the integer and display the result in hexadecimal.
XOR_op: Prompt the user for two hexadecimal integers. Exclusive-OR them together and display the result in hexadecimal.
You may refer to Programming Exercises #5 and #6 on page 239
Sample Run:
After menu displayed, I chose 1. I use "Call ReadChar" to get user input. However, ReadChar will not echo the char typed in terminal window. So I use:
call ReadChar
call WriteChar
The objective of the program is to implement a simple Boolean calculator for 32-bit integers. The program displays a menu to the user with various operations like AND, OR, NOT, XOR, and the option to exit. The program uses the Table-Driven Selection technique, user-defined procedures, and the Irvine32.inc library. Each operation is implemented as a separate procedure, which is called based on the user's choice.
The program starts by displaying a menu to the user, allowing them to select an operation or exit the program. The Table-Driven Selection technique is used to map the user's choice to the corresponding procedure. This technique involves using a table or data structure to associate values with actions or procedures.
When the user makes a choice, the program calls the corresponding procedure to perform the desired operation. For example, if the user selects AND, the program calls the AND_op procedure, which prompts the user for two 32-bit integer inputs and performs the bitwise AND operation on them.
Similarly, the program implements procedures for other operations such as OR, NOT, and XOR. Each procedure handles the specific logic and output based on the operation chosen by the user.
To support the program's functionality, the Irvine32.inc library is used. This library provides additional functions and utilities for input/output operations and working with 32-bit integers.
Overall, the program allows the user to perform Boolean operations on 32-bit integers through a menu-driven interface, utilizing user-defined procedures and the Table-Driven Selection technique for efficient and modular code organization.

Define a function myIncludes that accepts a string to search in, haystack, and a string to search for, needle. If the needle is in the haystack, return the boolean true. Otherwise, return false.
haystack is the first parameter and needle the second
do NOT use the string methods slice or includes!!!
HAVE TO USE SOME FORM OF NESTED LOOPS
Hint: A nested for loop would be helpful here! Also, you may want to use continue or break
The function `myIncludes` is designed to search for a specific string, `needle`, within another string, `haystack`. It uses a nested loop structure to iterate through each character of `haystack` and compare it with the characters of `needle`.
If a match is found, the function returns `true`; otherwise, it returns `false`. The implementation avoids using built-in string methods like `slice` or `includes` and instead relies on manual comparison using loops.
The `myIncludes` function takes two parameters, `haystack` and `needle`. It uses a nested loop structure to compare each character of `needle` with the corresponding characters in `haystack`. The outer loop iterates over each character of `haystack`, while the inner loop iterates over each character of `needle`.
Inside the inner loop, the function compares the current characters from `haystack` and `needle`. If they don't match, the inner loop continues to the next character in `needle`. If all characters in `needle` have been successfully compared and matched, the function returns `true` to indicate that `needle` is present in `haystack`.
If the inner loop completes without finding a match, the outer loop moves to the next character in `haystack`. The process continues until either a match is found, or all characters in `haystack` have been checked. If the outer loop completes without finding a match, the function returns `false` to indicate that `needle` is not present in `haystack`.
By using this nested loop structure and manual character comparison, the `myIncludes` function provides an alternative implementation to check for the presence of a substring within a larger string without relying on built-in string methods like `slice` or `includes`.

public double calculateAverage() {
double sum = 0;
for (double score : scores) {
sum += score;
}
return sum / scores.length;
}
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
TestScores testScores = new TestScores();
// Prompt the user to enter three test scores
System.out.print("Enter test score 1: ");
double score1 = scanner.nextDouble();
System.out.print("Enter test score 2: ");
double score2 = scanner.nextDouble();
System.out.print("Enter test score 3: ");
double score3 = scanner.nextDouble();
// Set the scores using setters
double[] scores = { score1, score2, score3 };
testScores.setScores(scores);
// Display each test score
System.out.println("Test Scores:");
for (int i = 0; i < scores.length; i++) {
System.out.println("Test " + (i + 1) + ": " + scores[i]);
}
// Calculate and display the average
double average = testScores.calculateAverage();
System.out.println("Average: " + average);
scanner.close();
}
}
Thus, this program uses a TestScores class that has a scores array, constructors, setters, getters, and a method to calculate the average.

Modify Points3D class to do the followings:
1. Overload the instream and outstream as friend method to
Poinst3D
2. Modify DisplayPoint method to display Points3D by calling its
base class DisplayPoint
The Points3D class needs to be modified to accomplish the following:
1. Overload the instream and outstream as friend method to Points3D.
2. Modify DisplayPoint method to display Points3D by calling its base class DisplayPoint. In order to implement the above modifications, we have to do the following steps:
Step 1: Overloading the instream and outstream as a friend function of Points3D class. The overloaded operator is a function that has the same name as the original function, but has a different parameter list and/or return type. When we overload an operator, we are defining its behavior for different types of operands. Below is the code that demonstrates overloading the instream and outstream as a friend method to Points3D: class Points3D
{
public:double x;
double y;
double z;
public:Points3D()
{
x = 0;
y = 0;
z = 0;
}
Points3D(double _x, double _y, double _z)
{
x = _x; y = _y; z = _z;
}
friend std::ostream& operator << (std::ostream& os, const Points3D& point);
friend std::istream& operator >> (std::istream& is, Points3D& point);};
std::ostream& operator << (std::ostream& os, const Points3D& point) {os << point.x << " " << point.y << " " << point.z << std::endl;
return os;
}
std::istream& operator >> (std::istream& is, Points3D& point) {is >> point.x >> point.y >> point.z;
return is;
}
Step 2: Modify DisplayPoint method to display Points3D by calling its base class DisplayPoint. The DisplayPoint method of the Points3D class can be modified to display Points3D by calling its base class DisplayPoint as shown in the code below:
class Points3D :
public Point
{
public:double x;
double y;
double z;
public:Points3D()
{ x = 0; y = 0; z = 0;
}
Points3D(double _x, double _y, double _z) : Point(_x, _y), x(_x), y(_y), z(_z)
{
}
void DisplayPoint() {Point::DisplayPoint();std::cout << "Z Coordinate: " << z << std::endl;
}
};
Therefore, the Points3D class is modified to overload the instream and outstream as friend method to Points3D and modify the DisplayPoint method to display Points3D by calling its base class DisplayPoint.

Write a Python program "Lab7b1.py" to complete the following: • Define a class Shape (to be used as a super class) with data attributes color, filled (you may define "filled" in whatever you prefer, such as 1-filled, 0-not filled; yes-filled, no-not filled, or using True/False, ...). • Define a subclass, Triangle, that extends class Shape, with 3 data attributes: s1, s2, s3 (for the 3 sides). Implement methods __init___ and __str___ in both of the classes • Implement methods, area() and perimeter(), for class Triangle. • You may implement other methods in the two classes as you like for "proper/convenient" operations on the objects of the classes. Define regular main() function in which proper inputs should be read from keyboard (you may need to use try-except) for the creations of 2~3 objects of Triangle and display the objects' properties, such as the color, whether filled or not, area, perimeter. Test your program and take 2 screenshots of running your program with different testing inputs.
The Python program "Lab7b1.py" creates a class hierarchy consisting of a superclass called "Shape" and a subclass called "Triangle." The Shape class has data attributes for color and filled status. The Triangle class extends the Shape class and adds three data attributes for the lengths of its sides. Both classes have init and str methods implemented. Additionally, the Triangle class has methods for calculating the area and perimeter of a triangle.
The main function allows the user to input values for creating 2-3 Triangle objects and displays their properties such as color, filled status, area, and perimeter. Screenshots of the program running with different inputs should be taken for testing purposes.
The program starts by defining a Shape class, which serves as the superclass for the Triangle class. The Shape class has data attributes for color and filled status, and the Triangle class extends Shape and adds three data attributes for the lengths of its sides. The init method is implemented in both classes to initialize the attributes, and the str method is implemented to provide a string representation of the objects.
In addition to the inherited methods, the Triangle class defines area() and perimeter() methods to calculate the area and perimeter of a triangle based on its side lengths. These methods use appropriate formulas to perform the calculations.
The main function is responsible for creating instances of the Triangle class based on user input. It prompts the user to enter values for the color, filled status, and side lengths of the triangles. The program uses try-except blocks to handle any potential input errors. After creating the objects, it displays their properties, such as the color, filled status, area, and perimeter.
To test the program with different inputs, screenshots should be taken at different stages, such as when entering the input values and when displaying the object properties. This helps ensure the program is functioning correctly and provides evidence of successful testing.

protocol.
TCP stands for Transmission Control Protocol while UDP stands for User Datagram Protocol. Both TCP and UDP are protocols for transmitting data over the Internet. TCP is a connection-oriented protocol that is reliable and guarantees message delivery. UDP, on the other hand, is a connectionless protocol that is faster but does not guarantee message delivery.
TCP (Transmission Control Protocol) is a connection-oriented protocol that is responsible for ensuring that all packets are transmitted correctly and in the right order. TCP provides guaranteed message delivery by resending lost packets and verifying that packets are received in the correct order.
UDP (User Datagram Protocol) is a connectionless protocol that is faster than TCP because it does not provide guaranteed message delivery. UDP is used when speed is more important than reliability. UDP doesn't guarantee message delivery. Packets may be lost in transit, and there is no mechanism for resending lost packets.UDP does not perform error checking to ensure that packets are received correctly. Therefore, UDP is faster and more efficient than TCP.
TCP is commonly used for applications such as email, file transfers, and web browsing. UDP is commonly used for real-time applications such as online gaming, video conferencing, and VoIP (Voice over Internet Protocol).

Write a program which tests the parity of an integer Write a program to convert a big number of seconds into days, hours, minutes, and seconds. Other exercises Test of primality: tell if an integer is
Here's the Java program to find parity of an integer.The time taken by above algorithm is proportional to the number of bits set. Worst case complexity is O(Log n).
import java.util.*;
import java.lang.*;
import java.io.*;
import java.math.BigInteger;
class GFG
{
/* Function to get parity of number n.
It returns 1 if n has odd parity, and
returns 0 if n has even parity */
static boolean getParity(int n)
{
boolean parity = false;
while(n != 0)
{
parity = !parity;
n = n & (n-1);
}
return parity;
}
/* Driver program to test getParity() */
public static void main (String[] args)
{
int n = 7;
System.out.println("Parity of no " + n + " = " +
(getParity(n)? "odd": "even"));
}
}
Parity of a number refers to whether it contains an odd or even number of 1-bits. The number has “odd parity” if it contains an odd number of 1-bits and is “even parity” if it contains an even number of 1-bits.
The main idea of the below solution is – Loop while n is not 0 and in loop unset one of the set bits and invert parity.
The parity of an integer is its attribute of being even or odd. Thus, it can be said that 6 and 14 have the same parity (since both are even), whereas 7 and 12 have opposite parity (since 7 is odd and 12 is even).
A different type of parity of an integer n is defined as the sum s_2(n) of the bits in binary representation, i.e., the digit count N_1(n), computed modulo 2. So, for example, the number 10=1010_2 has two 1s in its binary representation and hence has parity 2 (mod 2), or 0. The parities of the first few integers (starting with 0) are therefore 0, 1, 1, 0, 1, 0, 0, 1, 1, 0, 0, ... (OEIS A010060)

(1) List the two types of noises in Delta modulation.
(2) In asynchronous transmission, why do we keep the number of data bits between the start bit and stop element in a range of 5 to 8 in general?
(3) Which steps in PCM lose information in general so that the analog data cannot be fully recovered?
In Delta modulation, the two types of noises often encountered are granular noise and slope overload distortion. Asynchronous transmission typically uses 5 to 8 data bits to balance data integrity and transmission efficiency.
In Pulse Code Modulation (PCM), quantization and sampling steps might lead to information loss, impeding the full recovery of analog data. Delta modulation is an analog-to-digital and digital-to-analog signal conversion technique. Granular noise occurs when the step size is too small to track the input signal, while slope overload distortion happens when the step size is not large enough to keep up with the input signal's slope. The asynchronous transmission uses 5 to 8 data bits to maintain a good balance between efficiency and error detection capability. Fewer bits might compromise data integrity while more bits could reduce transmission efficiency. In PCM, the quantization step, which converts a continuous range of values into a finite range of discrete levels, can lead to information loss. Also, the sampling process, which captures the value of the signal at discrete intervals, can miss information that occurs between samples.
