Cache Block: Block 3 (index 3)
Result: Miss
Address 180:
Index: 180 mod 16 = 4
Cache Block: Block 4 (index 4)
Result: Miss
Address 43:
Index: 43 mod 16 = 11
Cache Block: Block 11 (index 11)
Result: Miss
Address 2:
Index: 2 mod 16 = 2
Cache Block: Block 2 (index 2)
Result: Miss
Address 19188:
Index: 19188 mod 16 = 12
Cache Block: Block 12 (index 12)
Result: Miss
Address 190:
Index: 190 mod 16 = 14
Cache Block: Block 14 (index 14)
Result: Miss
Address 14:
Index: 14 mod 16 = 14
Cache Block: Block 14 (index 14)
Result: Hit
Address 181:
Index: 181 mod 16 = 5
Cache Block: Block 5 (index 5)
Result: Miss
Address 44:
Index: 44 mod 16 = 12
Cache Block: Block 12 (index 12)
Result: Hit
Address 186:
Index: 186 mod 16 = 10
Cache Block: Block 10 (index 10)
Result: Miss
Address 253:
Index: 253 mod 16 = 13
Cache Block: Block 13 (index 13)

convert the following plain text to a cipher text using the
Mono-alphabetic substitution.
plain text-''Exam is today''
key-SELFLESSNESS
To convert the given plain text "Exam is today" into a cipher text using the mono-alphabetic substitution, we need a key that specifies the substitution mapping for each letter. In this case, let's use the key "SELFLESSNESS" as provided.
To create the cipher text, we will substitute each letter in the plain text with the corresponding letter from the key. Here's how it can be done:
Plain Text: E x a m i s t o d a y
Key: S E L F L E S S N E S S
Cipher Text: S E L F S S E S N E S S
Therefore, the cipher text for the given plain text "Exam is today" using the mono-alphabetic substitution and the key "SELFLESSNESS" would be "SELF SNESSNESS".
Note that in mono-alphabetic substitution, each letter in the plain text is replaced with a single corresponding letter from the key.
Why did UTF-8 replace the ASCII character-encoding standard?
256. Bits use the binary system, which is also known as the base-2 numeral system. So 2^8 allows us 256 values from 0 to 255
UTF-8 can store a character in more than one byte. UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. This allowed us to represent a lot more character types, like emoji.
255. There are 256 values in a byte, from the decimal number 0 to 255.
UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte, allowing for a wider range of character types, including emojis.
UTF-8, which stands for Unicode Transformation Format 8-bit, is a character encoding scheme that can represent characters from the Unicode character set. It is backward-compatible with ASCII, meaning that the first 128 characters of UTF-8 are the same as ASCII, ensuring that ASCII-encoded text can be correctly interpreted by UTF-8.
The ASCII character-encoding standard uses 7 bits to represent characters, allowing for a total of 128 different characters. However, as technology advanced and the need to support a broader range of characters arose, the limitations of ASCII became apparent. With only 128 characters, ASCII was unable to represent characters from other languages or symbols like emojis.
UTF-8 addressed this limitation by introducing a variable-length encoding scheme. It can use one to four bytes to represent a character, depending on the Unicode code point of the character. This flexibility allowed UTF-8 to encompass the entire Unicode character set, which includes over 137,000 characters.
By using multiple bytes, UTF-8 provides a larger number of possible values for character representation. The initial 128 characters are still represented by a single byte, ensuring backward compatibility with ASCII. However, the remaining characters, including a vast array of international characters, symbols, and emojis, can be represented using two, three, or four bytes as needed.
The adoption of UTF-8 as the dominant character encoding standard brought several advantages. It eliminated the need for different encoding schemes for different languages, streamlining internationalization efforts. It also allowed for seamless integration of various scripts and symbols into a single document or communication medium. The widespread use of UTF-8 has enabled better compatibility, interoperability, and globalization in the digital world.

The given table shows the subnet, broadcast address, and valid host range for questions 1 through 6. The valid host range is calculated by removing the network address and broadcast address from the total number of IP addresses in the subnet. The subnet is used to divide a larger network into smaller ones that are easier to manage and provide better security.
The broadcast address is used to send a message to all devices on a network simultaneously. A valid host range is the range of IP addresses that can be assigned to devices on a network. The range is calculated by subtracting the network address and the broadcast address from the total number of IP addresses in the subnet. The subnet mask is used to identify the network portion and the host portion of an IP address. The default subnet mask for a Class C network is 255.255.255.0.
In this lab, we are given an IP address and asked to find the subnet, broadcast address, and valid host range for six different questions. We first need to identify the subnet mask, which is given as 255.255.255.192. We can use this mask to calculate the subnet, broadcast address, and valid host range for each question. The subnet is calculated by performing a bitwise AND operation on the IP address and subnet mask.
The broadcast address is calculated by performing a bitwise OR operation on the IP address and the inverted subnet mask. The valid host range is calculated by subtracting the network address and the broadcast address from the total number of IP addresses in the subnet.

Programming Project #1 – Day Planner
In this project we will develop classes to implement a Day Planner program. Be sure to develop the code in a step by step manner, finish phase 1 before moving on to phase 2.
Phase 1
The class Appointment is essentially a record; an object built from this class will represent an Appointment in a Day Planner . It will contain 5 fields: month (3 character String), day (int), hour (int), minute (int), and message (String no longer then 40 characters).
Write 5 get methods and 5 set methods, one for each data field. Make sure the set methods verify the data. (E.G. month is a valid 3 letter code). Simple error messages should be displayed when data is invalid, and the current value should NOT change.
Write 2 constructor methods for the class Appointment . One with NO parameters that assigns default values to each field and one with 5 parameters that assigns the values passed to each field. If you call the set methods in the constructor(s) you will NOT need to repeat the data checks.
Write a toString method for the class Appointment . It should create and return a nicely formatted string with ALL 5 fields. Pay attention to the time portion of the data, be sure to format it like the time should be formatted ( HH : MM ) , a simple if-else statement could add a leading zero, if needed.
Write a method inputAppointment () that will use the class UserInput from a previous project, ask the user to input the information and assign the data fields with the users input. Make sure you call the UserInput methods that CHECK the min/max of the input AND call the set methods to make sure the fields are valid.
Write a main() method, should be easy if you have created the methods above, it creates a Appointment object, calls the inputAppointment () method to input values and uses the method toString() print a nicely formatted Appointment object to the screen. As a test, use the constructor with 5 parameters to create a second object (you decide the values to pass) and print the second object to the screen. The primary purpose of this main() method is to test the methods you have created in the Appointment class.
Phase 2
Create a class Planner , in the data area of the class declare an array of 20 Appointment objects. Make sure the array is private (data abstraction).
In this project we are going to build a simple Day Planner program that allow the user to create various Appointment objects and will insert each into an array. Be sure to insert each Appointment object into the array in the proper position, according to the date and time of the Appointment . This means the earliest Appointment object should be at the start of the array, and the last Appointment object at the end of the array.
Please pre load your array with the following Appointment objects:
Mar 4, 17:30 Quiz 1
Apr 1, 17:30 Midterm
May 6, 17:30 Quiz 2
Jun 3, 17:30 Final
Notice how the objects are ordered, with the earliest date at the start of the array and the latest at the end of the array.
The program will display the following menu and implement these features:
A)dd Appointment , D)elete Appointment , L)ist Appointment , E)xit
Some methods you must implement in the Planner class for this project:
Planner () constructor that places the 4 default Appointment objects in the array
main() method the creates the Planner object, then calls a run method
run() method that displays the menu, gets input, acts on that input
compareAppointment (Appointment A1, Appointment A2) method that returns true if A1 < A2, false otherwise
insertAppointment (Appointment A1) places A1 in the proper (sorted) slot of the array
listAppointment () method lists all Appointment objects in the array (in order) with a number in front
deleteAppointment () delete an object from the array using the number listAppointment () outputs in front of the item
addAppointment () calls inputAppointment () from the Appointment class and places it in the proper position of the array. Use an algorithm that shifts objects in the array (if needed) to make room for the new object. DO NOT sort the entire array, just shift objects
You may add additional methods to the Planner and Appointment classes as long as you clearly document 'what' and 'why' you added the method at the top of the class. The Appointment class could use one or more constructor methods. DO NOT in any way modify the UserInput class. If it so much as refers to a day or month or anything else in the Planner or Appointment class there will be a major point deduction.
The goal of the Day Planner programming project is to implement a Java program that allows users to create and manage appointments.
What is the goal of the Day Planner programming project?
In this programming project, the goal is to create a Day Planner program using Java. The project is divided into two phases.
Phase 1 focuses on implementing the Appointment class. The Appointment class represents an appointment in the Day Planner and has five fields: month (a 3-character String), day (int), hour (int), minute (int), and message (String, up to 40 characters).
The phase requires writing getter and setter methods for each data field, two constructor methods (one with no parameters and one with 5 parameters), a toString method for formatting the appointment information, and an inputAppointment method to interactively gather input from the user.
Phase 2 involves creating the Planner class. It includes declaring a private array of 20 Appointment objects. The goal is to build a Day Planner program that allows the user to create and manage appointments.
The Planner class should have methods like compareAppointment, insertAppointment, listAppointment, deleteAppointment, and addAppointment to handle operations such as comparing appointments, inserting appointments in the correct position, listing appointments, deleting appointments, and adding new appointments.
The main method should create a Planner object and call a run method to display a menu, gather user input, and perform actions based on the user's choice. The Planner class should maintain the array of appointments in sorted order, with the earliest appointment at the start and the latest at the end.
Overall, this project focuses on creating classes and methods to implement a functional Day Planner program with appointment management capabilities.

Write a MATLAB function [output] = leapyear (year) to determine if a given year is a leap year. Remember the MATLAB input variable year can be a vector. The output variable too can be vector. Inside the MATLAB function use the length function to determine the length of year. Inside the MATLAB function, use a for-loop to perform the leap-year logical test for each year in the input vector-and store the logical result in the output vector. The output vector should evaluate true (logical 1) or false (logical 0) during the internal for-loop evaluation. Successfully completing the function now allows a user to use vectorization methods to count the number of leap years between a range of years. For example, to evaluate the number of leap years between 1492 and 3097 the MATLAB command sum(leapyear (1492:3097)) is issued - without an external for-loop driving the computation. For the function to be used in the command line, make sure that it appears at the top directory in your MATLAB path. You can find yours by typing the command → matlabpath. Do not adjust the MATLABPATH, just place your . m file in the top directory in the path. Grading: 16 points for leapyear. m,4 points for producing the correct answer in the command line for the number of leap years between 1492 to 3097 using the command, sum(leapyear (1492:3097) ).
MATLAB function leapyear checks if a given year or vector of years is a leap year, allowing vectorization for efficient computation.
The provided MATLAB function, leapyear.m, determines whether a given year or a vector of years is a leap year or not. It utilizes the length function to determine the size of the input vector and employs a for-loop to perform the leap-year logical test for each year in the input vector. The result is stored in the output vector, where true represents a leap year (logical 1) and false represents a non-leap year (logical 0). This function enables users to use vectorization methods, such as the sum function, to count the number of leap years between a range of years without the need for an external for-loop.
The leapyear.m MATLAB function takes a year or a vector of years as input. It first determines the length of the input vector using the length function. This allows the function to handle both single years and vectors of years.
Next, a for-loop is used to iterate over each year in the input vector. Within the loop, a leap-year logical test is performed for each year. The result of the test, either true or false, is stored in the corresponding position of the output vector.
To determine if a year is a leap year, the function checks the following conditions:
The year must be divisible by 4.
If the year is divisible by 100, it must also be divisible by 400.
If both conditions are satisfied, the year is considered a leap year, and the logical result is set to true (1). Otherwise, it is considered a non-leap year, and the logical result is set to false (0).
By using this leapyear.m function, users can easily count the number of leap years between a range of years by applying vectorization methods. For example, the command sum(leapyear(1492:3097)) will return the count of leap years between the years 1492 and 3097. The function facilitates efficient and convenient leap year calculations in MATLAB without the need for explicit looping.

(b) (1) Draw a single flow Image to show the encapsulation process of a message from the application layer to the link layer, and its transmission via a switch and router, to a destination. Briefly describe differences among the concept of message, segment, datagram and frame. [5 marks] (11) Suppose a 4000 bytes datagram needs to be transmitted and the maximum transmission unit (MTU) of IP datagram is 1500 bytes. How many fragments are needed for transmitting such a datagram and what are the length of each fragmentation? [Hint: the IP overhead is 20 bytes) [4 marks]
Here's a single flow diagram to show the encapsulation process of a message from the application layer to the link layer, and its transmission via a switch and router to a destination:
Application Layer
|
Transport Layer
|
Network Layer
|
Link Layer (Encapsulation)
|
Switch
|
Router
|
Link Layer (Decapsulation)
|
Network Layer
|
Transport Layer
|
Application Layer
In this diagram, the message is encapsulated at each layer of the protocol stack as it travels down from the application layer to the link layer. At the link layer, the message is transmitted through a switch and router to reach its destination. At the receiving end, the message is decapsulated at each layer to extract the original message.
The concept of message, segment, datagram, and frame are used in different network protocols and refer to different types of data structures:
Message: A message is an abstract concept used in the application layer that represents the data being exchanged between two applications. For example, an email message or a file transfer.
Segment: A segment is a data structure used in transport layer protocols like TCP that represents a portion of a message. Segmentation is used to break up large messages into smaller segments for more efficient transmission.
Datagram: A datagram is a data structure used in network layer protocols like IP that represents a packet of information. It includes the source and destination IP addresses as well as other information needed for routing.
Frame: A frame is a data structure used in link layer protocols like Ethernet that represents a unit of data being transmitted over a physical link. It includes information like MAC addresses for identifying the source and destination devices.
For the second part of the question, we need to fragment a 4000-byte datagram with an IP overhead of 20 bytes into packets with a maximum size of 1500 bytes.
We can calculate the number of fragments required using the following formula:
Number of fragments = (Datagram size + IP overhead) / MTU
In this case, we have:
Number of fragments = (4000 + 20) / 1500 = 3.01
Since the number of fragments is not a whole number, we need to round up to the nearest integer, which gives us a total of 4 fragments.
To determine the length of each fragment, we can use the following formula:
Fragment length = MTU - IP overhead
For the first 3 fragments, the length will be 1480 bytes (1500 - 20), and for the last fragment, the length will be 60 bytes (80 - 20).

The entropy of the four-symbol source is 1.8464 bits/symbol. The redundancy is 0.1536 bits/symbol. The information rate is 1.6928 bits/symbol.
Entropy is a measure of the average amount of information contained in each symbol of a source. In this case, the entropy of the four-symbol source can be calculated using the formula:
Entropy = - ∑(p_i * log2(p_i))
where p_i represents the probability of selecting symbol i. Given the symbol selection probabilities of 0.5, 0.2, 0.2, and 0.1 for symbols A, B, C, and D respectively, we can calculate the entropy as follows:
Entropy = -(0.5 * log2(0.5) + 0.2 * log2(0.2) + 0.2 * log2(0.2) + 0.1 * log2(0.1))
≈ 1.8464 bits/symbol
Redundancy is the difference between the entropy and the average length of the code used to represent each symbol. In this case, since the source is memoryless, we can use a prefix-free code, such as Huffman coding, to represent each symbol. The average code length can be calculated as the sum of the products of the code lengths and their respective probabilities:
Average code length = ∑(code_length_i * p_i)
The redundancy is then calculated as:
Redundancy = Average code length - Entropy
The information rate is the difference between the baud rate (1024 symbol/s) and the redundancy:
Information rate = Baud rate - Redundancy
By calculating the average code length and using the above formulas, we can determine the redundancy and information rate of the four-symbol source.

Explain the following defects in hot forging: - Cold shuts - Warping of the part - Laps
In hot forging, there are certain defects that can occur during the forging process. These defects include cold shuts, warping of the part, and laps. Let's take a closer look at each of these defects.
Cold Shuts:
A cold shut is a defect that occurs when two parts of the material fail to properly weld together during the forging process. This results in a line that is visible on the surface of the material. Cold shuts can occur due to a number of reasons, including improper die design, insufficient temperature, and improper feeding.
Warping of the Part:
Another common defect in hot forging is warping of the part. This occurs when the part becomes distorted during the forging process, resulting in an uneven surface. This can be caused by several factors, including uneven heating, improper placement of the part, and improper die design.
Laps:
Laps are another common defect that can occur in hot forging. Laps are caused by insufficient material flow during the forging process. This results in a thin line of material that extends from the surface of the part. Laps can be caused by several factors, including improper die design, insufficient temperature, and improper feeding.
In order to prevent these defects from occurring, it is important to properly design the die, use the correct temperature, and feed the material properly. Additionally, the operator should be properly trained to identify and address any defects that occur during the forging process.

\( 0 . \) Note: - The array is changed in place (i.e. the method updates the parameter array and it does not return a new array). - Do not import the java. util package. This has been done for you as
The task is to implement a method in Java that moves all occurrences of the value 0 to the end of an array while preserving the order of the non-zero elements. The method should modify the array in place without returning a new array. The Java `util` package should not be imported for this task.
To solve this task, you can use a two-pointer approach. Initialize two pointers, `left` and `right`, both starting from the beginning of the array. Iterate through the array with the `right` pointer, and whenever a non-zero element is encountered, swap it with the element at the `left` pointer. Increment `left` by 1 after each swap.
This approach ensures that all non-zero elements are moved to the beginning of the array, while all zeros are shifted towards the end. Once the iteration is complete, all non-zero elements will be at the front of the array, and all zeros will be at the end.
Here's an example implementation:
```java
public static void moveZerosToEnd(int[] array) {
int left = 0;
int right = 0;
while (right < array.length) {
if (array[right] != 0) {
int temp = array[left];
array[left] = array[right];
array[right] = temp;
left++;
}
right++;
}
}
```
By calling the `moveZerosToEnd` method and passing the desired array as a parameter, the array will be modified in place, with all zeros moved to the end while preserving the order of non-zero elements.

Payroll Software A Programming Company uses freelance programmers for some of their projects and they pay them at a given hourly rate. Sometimes the projects are so big such that they request the freelance programmers to exceed the weekly contracted 40 hours, and then pay the extra hours (excess of 40 hours) at an overtime rate. The total hours, including the extra hours, should not be over 60 hours and can never be zero or below. The normal hourly rate is R520.45 per hour and the overtime rate factor is 1.4072. Everyone of their ten (10) freelance programmers must submit weekly hours for the calculation of their salaries. Design a C++ Program that will accept into parallel arrays the following details: Name, Surname and hours worked. Note that the name and surname should be stored separately. We assume that the surnames are unique for each programmer. The salary calculations done per employee are: Basic Salary (rate and hours worked), Medical Allowance (Basic Salary and 8.2%), Data Allowance (Basic Salary and 5%), Gross Pay (Basic Salary, Medical Allowance and Data Allowance), PAYEE (Gross Pay and 9.34%), UIF (Gross Pay and 1%), and Net Pay (Gross Pay, PAYEE and UIF).
Your program should be menu driven with the following options:
[C]apture Employee Details
[L]ist Employee Details
[A]ll Employees Payslips
[S]ingle Employee Payslip
[E]xit
Use a switch statement to evaluate the menu options and consider the small or capital letters for each option. The program should use functions to do the following: Capture all employee details (name, surname, hours), Display all employee details from the arrays, Display all the employees’ payslips, Display a single employee’s salary (this requires you to search for the employee using the surname only) and therefore the other function should search for the index number for the location of the employee’s surname in the array. Note that, the display payslip function should display a payslip for only one employee, it should only accept the name, surname and hours worked of a single employee and then make the calculations from within the function. You can use variables for the calculations within this function. Please format the payslip output as we did in the lesson. You are not limited to the suggested functions above, you can have more functions if you feel you need them, but the ones listed above are compulsory.
The C++ program should be designed to provide the following options: capturing employee details, listing employee details, generating payslips for all employees, generating a payslip for a single employee, and exiting the program. These options will be evaluated using a switch statement based on user input. The program should utilize parallel arrays to store the name, surname, and hours worked for each employee. Functions should be implemented to perform tasks such as capturing employee details, displaying employee details, generating payslips, and searching for an employee's surname in the array. The payslip calculations, including basic salary, medical allowance, data allowance, gross pay, PAYEE, UIF, and net pay, should be performed within the appropriate functions. The program should display the payslip output in the desired format.
The C++ program will be structured to handle the payroll calculations and management for a programming company that employs freelance programmers. The program will use parallel arrays to store the necessary employee details, including their names, surnames, and hours worked. The menu-driven approach will provide a user-friendly interface for interacting with the program.
When the user selects the "Capture Employee Details" option, the program will prompt for and store the relevant information in the corresponding arrays. This function ensures that all employee details are accurately captured and stored for future use.
The "List Employee Details" option will display all the employee details stored in the arrays. This function allows the user to view the names, surnames, and hours worked for each employee in a convenient format.
The "All Employees Payslips" option generates payslips for all the employees. This function will iterate through the arrays, performing the necessary calculations for each employee to determine their basic salary, medical allowance, data allowance, gross pay, PAYEE, UIF, and net pay. The payslips will be displayed in the desired format, providing a comprehensive overview of the employees' salaries.
The "Single Employee Payslip" option allows the user to generate a payslip for a specific employee by searching for their surname in the array. This function will locate the employee's index number and perform the required salary calculations for that employee. The payslip will be displayed in the specified format.
The program also includes an "Exit" option to gracefully terminate the program when the user is done with their tasks.
Overall, this program provides an efficient and user-friendly solution for managing the payroll calculations and generating payslips for freelance programmers in a programming company.
