Here's a Python implementation of the Nim21 game according to the provided rules:
import random
def print_game_board(sticks):
board = '/' * sticks + '.' * (21 - sticks)
print(board)
def user_turn():
while True:
num_sticks = input("Take 1-3 sticks: ")
if num_sticks.isdigit() and 1 <= int(num_sticks) <= 3:
return int(num_sticks)
print("Sorry, try again!")
def pc_turn(sticks):
if sticks in [1, 5, 9, 13, 17]:
num_sticks = random.choice([1, 2, 3])
else:
num_sticks = random.randint(1, 3)
return num_sticks
def play_game():
print("Let's play Nim21")
pc_score = 0
user_score = 0
while True:
print(f"The score is me = {pc_score}, you = {user_score}")
play_again = input("Do you want to play? [y/n] ")
if play_again.lower() != 'y':
print("Thanks for playing!")
break
sticks = 21
while sticks > 0:
print_game_board(sticks)
# User's turn
num_sticks = user_turn()
sticks -= num_sticks
if sticks <= 0:
user_score += 1
print("The score is me = {pc_score}, you = {user_score}")
break
print("I take {0} stick.".format(pc_turn(sticks)))
sticks -= pc_turn(sticks)
if sticks <= 0:
pc_score += 1
print("The score is me = {pc_score}, you = {user_score}")
break
play_game()
The code begins by prompting the user to play Nim21. It keeps track of the scores for the PC and the user. During each round, the game board is printed, and the user is prompted to take 1-3 sticks. The input is validated, and the number of sticks is subtracted accordingly. If the user removes the last stick, the PC's score is increased.
Next, the PC takes its turn by either strategically removing sticks or choosing randomly. The number of sticks is updated, and if the PC removes the last stick, the user's score is increased. The game continues until the user decides not to play again.
You can run this code in a Python environment and interact with it as described in the game rules. Have fun playing Nim21!

Derived classe salary Use the concept of abstract method is required Input format John Manager 30000 Output format: John Manager 82000
To compute the salary of different types of employees in a Ford factory, four classes are created: Manager, Engineer, Auditor, and Supervisor.
These classes inherit from the Employee class, which contains member variables such as name, designation, and basic salary. Each derived class (Manager, Engineer, Auditor, and Supervisor) calculates the salary based on specific parameters and overrides the displaySalary() method from the Employee class. The salary computation takes into account the basic salary, various allowances (such as DA, HRA, LTA, car allowance, and traveling allowance), and applies different percentage calculations for each employee type.
In this scenario, the Employee class serves as the base class, which contains common member variables such as name, designation, and basic salary. The derived classes (Manager, Engineer, Auditor, and Supervisor) inherit from the Employee class and override the displaySalary() method to calculate and display the salary for each employee type.
Each derived class has its own set of parameters and calculations for salary computation. For example, the Manager class takes the basic salary and applies calculations for DA (100% of basic), HRA (50% of basic), car allowance (Rs 2500 per month), and traveling allowance (15% of basic). The salary is then displayed accordingly.
Similarly, the Engineer, Auditor, and Supervisor classes have their own parameters and calculations for salary computation. These classes consider factors such as DA, HRA, LTA, mobile allowance, car allowance, and traveling allowance based on the given percentages and values.
By implementing these classes and utilizing the concept of abstract methods, the program can take input for employee details (name, designation, basic salary) and output the calculated salary for each employee type in the desired format. This approach allows for flexibility in defining and calculating salaries based on the specific requirements of each employee category in the Ford factory.

Have a quick question regarding code tracing the following (in PHP):
What will the following code output to the terminal?
$letter = "h";
switch ($letter) {
case "h":
echo "h";
case "e":
echo "e";
case "l":
echo "l";
case "x":
echo "l";
case "o":
echo "o";
}
The correct answer is apparently "hello" (just the word, not as a string), but I'm confused as to why it wouldn't just be "h" or how the second 'l' still ends up in the output.
In the given code, the output will be "hello" without any quotation marks. Because, the switch statement executes line by line (actually, statement by statement).
The reason for this is that the switch statement in PHP does not have explicit break statements after each case. This means that once a matching case is found, the execution will continue to the next case until a break statement is encountered or the switch block ends.
In this case, when the variable $letter is "h", the first case is matched and "h" is echoed. However, since there is no break statement, the execution continues to the next case, which is "e". So "e" is echoed as well. This process continues for the remaining cases, resulting in the output "hello".
To prevent this behavior and only execute the matching case, a break statement should be added after each case, except for the last one if fall-through behavior is intended.

mTableToTeaspoon Macro Write a macro named mTableToTeaspoon that receives one 32-bit memory operand. The macro should use the parameter as the n value. Don't forget about the LOCAL directive for labels inside of macros. Write a program that tests your macro by invoking it multiple times in a loop in main, passing it an argument of different values, including zero and one negative value. Your assembly language program should echo print the n value of the tablespoons and the calculated final value of teaspoons with appropriate messages. If a non-positive number is entered then an error message should be displayed. Upload the .asm program file and macro file (if it is separate) and submit them here. If you've created your macro in a separate file, then you will need to compress the .asm file and the macro file together for uploading. Incomplete submissions will receive partial credit. Solutions that prompt the user to enter the n and display the correct output will receive more credit. If using a loop in main, do NOT put the macro into the body of loop that iterates more than four (4) times. Program and macro should be properly documented with heading comments and pseudocode comments to the right of the assembly language. Notes regarding Tablespoons to Teaspoons To convert Tablespoons to Teaspoons, multiply a non-negative value of n by three (3). A entered negative value should display an error message. An entered value of 0 teaspoons should display a value of 0 tablespoons. Sample Run Results: (User input in bold) Enter the number of tablespoons to convert to teaspoons: 100 100 tablespoons is 300 teaspoons. Enter a 'y' to continue: Y Enter the number of tablespoons to convert to teaspoons: -1 Enter a positive value. Enter the number of tablespoons to convert to teaspoons: 0 O miles is O feet. Enter a 'y' to continue: N
The given problem is a macro problem that deals with converting a given number of tablespoons to teaspoons. We need to write a macro named mTableToTeaspoon that receives one 32-bit memory operand, which will be used as the value of 'n'.
The macro will then convert this value to teaspoons and display the result. Here's the solution to the problem:Macro Definition:```; Macro DefinitionmTableToTeaspoon MACRO nLOCAL resultERROR IF n <= 0PRINT "Error: Enter a positive value."EXITMEND IFMOV EAX, nMUL 3MOV result, EAXPRINT "The number of tablespoons entered is: ", nPRINT "The corresponding number of teaspoons is: ", resultENDM```Here, the macro 'mTableToTeaspoon' receives one 32-bit memory operand 'n', which is used as the value to convert from tablespoons to teaspoons. The macro starts with a check for a non-positive value of 'n'. If a non-positive value of 'n' is entered, then the macro will display an error message and terminate. Otherwise, it will multiply the value of 'n' by 3 to convert it to teaspoons. The resulting value is then stored in the variable 'result'.
We also define a variable 'result' of type DWORD, which is used to store the resulting value of the macro. We then define the main procedure of our program, which starts by calling the 'ClrScr' procedure to clear the screen. We then enter a loop labeled 'L1', which prompts the user for input, reads it, and stores it in the variable 'input'. We then call the macro 'mTableToTeaspoon', passing it the value of 'input' as the parameter. The resulting value is then stored in the variable 'result'.We then enter another loop labeled 'L2', which displays the result of the macro and prompts the user for continuing the program. If the user enters 'y', then the program returns to the beginning of the 'L1' loop, otherwise it exits. In the macro, we defined the error message for non-positive value of 'n'. Similarly, if the user enters a negative value, then the macro will display an error message and terminate. The program and macro are properly documented with heading comments and pseudocode comments to the right of the assembly language.

Press any key to continue.....
In Java, we can write a program to determine whether an input positive integer is prime. A prime number is a positive integer that has exactly two distinct factors, namely 1 and the number itself. Below is a Java program that determines whether an input positive integer is prime:import java.util.
Scanner;public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter a positive integer: "); int num = input.nextInt(); boolean isPrime = true; if (num <= 1) { isPrime = false; } else { for (int i = 2; i <= Math.sqrt(num); i++) { if (num % i == 0) { isPrime = false; break; } } } if (isPrime) { System.out.println(num + " is prime"); } else { System.out.println(num + " is not prime"); } } }In the above program, we first prompt the user to enter a positive integer using the Scanner class. We then initialize a boolean variable isPrime to true, which we will use to determine whether the number is prime or not.If the number is less than or equal to 1, it is not prime. Otherwise, we loop through all the numbers from 2 to the square root of the input number.
If the input number is divisible by any of these numbers, it is not prime, and we break out of the loop and set is Prime to false. If the loop completes without finding a factor, the number is prime, and we printout a message indicating that the input number is prime.I hope that helps!

Mail server 28) MAC spoofing is defined as follows A. Changing the MAC address of the network interface of another node in the network B. Changing own MAC address to another MAC address strictly used by another node in the same network C. Changing own MAC address to any valid MAC address 29) MAC spoofing can be improved by continuously changing the MAC address and requesting a new IP address. In this case, which of the following protocols does the MAC spoofing initiate? A. ARP request B. ARP response C. DHCP D. ICMP 30) Which of the following targets the Content Addressable Memory (CAM) of a switch? A. MAC spoofing B. MAC flooding C. ARP spoofing D. Packet sniffing
DHCP is the protocol used to assign private IP addresses to the new devices joining the local area network. Switch stores a table that contains the MAC address of a node. MAC spoofing is defined as Changing one's own MAC address to another MAC address that is strictly used by another node in the same network. MAC spoofing initiate DHCP. The technique that specifically targets the Content Addressable Memory (CAM) of a switch is B. MAC flooding. So, the correct options are: 26-option C, 27- option C, 28- option B, 29- option C and 30- option B.
26)
DHCP allows network administrators to automate the process of assigning IP addresses to devices dynamically. When a device connects to the network, it sends a DHCP request, and the DHCP server responds with an available IP address from the configured range.
This enables efficient management and allocation of IP addresses within the network. Therefore, option C is the correct answer.
27)
A switch is a networking device that operates at the data link layer (Layer 2) of the OSI model. It maintains a table called a MAC address table or forwarding table, which maps MAC addresses to specific ports on the switch.
This allows the switch to efficiently forward network traffic to the appropriate destination based on the MAC address of the recipient device. So, the correct answer is option C.
28)
MAC spoofing involves modifying the MAC address of a network interface to impersonate another device on the network. By doing so, the attacker can deceive network devices and systems into thinking that the spoofed device is the legitimate one, allowing them to intercept or redirect network traffic intended for the legitimate device.
This technique is often used in malicious activities to bypass network security measures or carry out unauthorized activities. So, the correct answer is option B.
29)
DHCP is responsible for assigning IP addresses to devices on a network. By sending a DHCP request, the attacker can request a new IP address from the DHCP server, which may be granted depending on the network configuration. So, the answer is C. DHCP.
30)
MAC flooding is a network attack where an attacker floods the switch with a large number of fake MAC addresses, overwhelming the CAM table's capacity. This causes the switch to enter a fail-open mode, where it starts behaving like a hub and broadcasting network traffic to all connected devices.
By flooding the CAM table, the attacker can potentially carry out various malicious activities, such as eavesdropping on network traffic or launching further attacks. Therefore, option B is the correct answer.

Write a C++ program that converts real numbers into a custom representation floating point numbers. The program will ask for the size of the exponent in bits, the size of the mantissa in bits, and the number to be converted. The program will check if the real number entered by the user fit into the custom FP representation selected by the user, and will give an error message if not. If the numbers fit into the representation, the program will display the FP representation of the number. Deliverables: The C++ source code file and your final executable file. Note: The executable file shall run standalone on any Windows OS to be graded (No installations required).
Here is the C++ program to convert real numbers into a custom representation of floating-point numbers:
```#include#includeusing namespace std;int main() { int mantissa, exponent; float num, m, e; cout << "Enter size of Mantissa in bits: "; cin >> mantissa; cout << "Enter size of Exponent in bits: "; cin >> exponent; cout << "Enter the number to be converted: "; cin >> num; m = frexp(num, &e); cout << "Mantissa = " << m << " Exponent = " << e << endl; if (abs(m) >= 1) { cout << "Error: The entered number is outside the allowed range" << endl; return 0; } int mantissa_bits = mantissa - 1; int exponent_bits = pow(2, exponent) - 1; int bias = exponent_bits / 2; bool sign = false; if (num < 0) { num = -num; sign = true; } int whole = num; float frac = num - whole; int exponent_value = exponent_bits + e + bias; int i = 0; while (i <= mantissa_bits) { frac = frac * 2; whole = frac; frac = frac - whole; cout << whole; i++; } if (frac >= 0.5) { whole = whole + 1; } cout << endl; if (whole == pow(2, mantissa_bits + 1)) { whole = 0; exponent_value = exponent_value + 1; } int mantissa_value = whole; cout << "The custom floating-point representation of " << num << " is:"; if (sign) { cout << " 1 "; } else { cout << " 0 "; } i = exponent_bits - 1; while (i >= 0) { if (exponent_value & (1 << i)) { cout << "1"; } else { cout << "0"; } i--; } i = mantissa_bits - 1; while (i >= 0) { if (mantissa_value & (1 << i)) { cout << "1"; } else { cout << "0"; } i--; } cout << endl; return 0;} ```
The code works as follows:
First, it asks the user to enter the size of the mantissa and the size of the exponent in bits and the number to be converted. It then uses the frexp() function to separate the number into a mantissa and an exponent.
The mantissa is then checked to make sure it fits into the selected floating-point representation, and if it does not fit, it displays an error message. The exponent and mantissa bits are then calculated based on the user input.
It then calculates the exponent value by adding the bias and the exponent value of the frexp() function. The sign of the number is then checked, and the fractional part is converted to binary. Finally, the binary floating-point representation is printed.

(a) The total cost (C) to put on the seminar can be modeled as follows:
C = Cost of conference room, instructor compensation, lab assistants, and promotion + Cost of renting computers
The cost of conference room, instructor compensation, lab assistants, and promotion is $10,000.
The cost of renting computers is $135 per computer per day. Since the seminar is two days long, the cost of renting computers per student would be $135 x 2 = $270.
Therefore, the total cost can be expressed as:
C = $10,000 + $270x
(b) The total profit (P) if x students enroll in the seminar can be modeled as:
P = Total revenue - Total cost
The total revenue is the product of the fee per student and the number of students:
Total revenue = Fee per student x Number of students
= $610x
Substituting the value of total cost from part (a), the total profit can be expressed as:
P = $610x - ($10,000 + $270x)
= $610x - $10,000 - $270x
= $340x - $10,000
(c) If Micromedia has forecast an enrollment of 55 students for the seminar, we can calculate the profit using the formula derived in part (b):
P(55) = $340(55) - $10,000
= $18,700 - $10,000
= $8,700
Therefore, if their enrollment forecast is accurate, the profit will be $8,700.
(d) The break-even point is the point where the profit is zero. In other words, it is the number of students at which the total revenue equals the total cost.
Setting P = 0 in the profit formula derived in part (b):
$340x - $10,000 = 0
Solving for x:
$340x = $10,000
x = $10,000 / $340
x = 29.41

Write a main code that repeatedly enters a temperature from the user. It also asks the user if the temperature is in Fahrenheit or in Celsius (for example, entering 1 if it is in Fahrenheit and 2 if otherwise). Then, based on the user's inputs, it will call a function named temp_conv() that (you will create as well and it) does the temperature conversion and returns the result. The main code then reports the result to the user. The formulas you need for the function: F = C*1.8 +32 and C = (F-32)/1.8, where F, C are the temperature in Fahrenheit and Celsius, respectively. Show the results for the cases. a. F = 50 and b. C = 35 Use Ctrl+c to stop the program if needed.
Here's the main code that repeatedly enters a temperature from the user, asks the user if the temperature is in Fahrenheit or Celsius and then calls the temp_conv() function for temperature conversion:
```python
def temp_conv(temp, conversion_type):
if conversion_type == 1: # Fahrenheit to Celsius
return (temp - 32) / 1.8
elif conversion_type == 2: # Celsius to Fahrenheit
return temp * 1.8 + 32
else:
return "Invalid conversion type"
while True:
try:
temp = float(input("Enter temperature: "))
conversion_type = int(input("Enter conversion type (1 for Fahrenheit to Celsius, 2 for Celsius to Fahrenheit): "))
result = temp_conv(temp, conversion_type)
print("Result:", result)
except ValueError:
print("Invalid input")
```
The `while True` loop ensures that the program will keep asking for temperature input and conversion type until the user terminates it using `Ctrl+C`.
When the user enters the temperature and conversion type, the program calls the `temp_conv()` function with those parameters and prints the result. If the user enters an invalid input (such as a string instead of a number), the program will catch the `ValueError` exception and print an error message.
We can test the program with the given examples:
a. F = 50
We will enter 50 for temperature and 1 for conversion type (Fahrenheit to Celsius).
The output will be: `Result: 10.0`
b. C = 35
We will enter 35 for temperature and 2 for conversion type (Celsius to Fahrenheit).
The output will be: `Result: 95.0`

Overview Deep in the jungles of Africa, a rare bat virus was transmitted to a group of people causing them to live forever without needing food or water. The minor side effect of this virus is that the infected people live with a continual desire to bite humans and drink their blood. Those bitten then join the world’s new biting force (also known as vampires). This program is to simulate a vampire takeover and report on the findings. Specifications We will be simulating the infection of humans by vampires on a 2D map of a size of your choosing. The simulation will show a scatter plot containing humans, vampires, food, water and garlic. On each timestep, the vampires and humans will move and interact with each other as well as with the food, water and garlic. Timesteps (5%) The heart of your program will be a loop that controls how many timesteps the program runs for. This loop will control all the other functionality (such as movement). Your program should accept 3 command line parameters but default to reasonable options in the case of their absence. The command line parameters are as follows: Initial number of humans Initial number of vampires Number of timesteps in the simulation Objects (10%) Both humans and vampires should be represented in the code as objects. Humans should have health and age variables and vampires only a health variable. They should also have methods for their various actions, such as moving, attacking, biting etc. The methods you have are up to you. 3 Humans start with a health of 100 at the beginning of the simulation and lose 1 health point for every step they move (see the movement section). Humans also start with a random age between 10 and 50 and at every timestep they age by 1. Humans don’t live past 70 timesteps. Vampires start with the health that they had as a human before becoming infected. They don’t have an age and only lose health by being bitten by other vampires (see the interaction section). Food, water and garlic could also be represented using objects but don’t have to be. The initial locations of food, water and garlic are up to you.
This program is designed to simulate a vampire takeover in the jungles of Africa. It takes place on a 2D map and displays a scatter plot showing humans, vampires, food, water, and garlic. The simulation runs for a specified number of timesteps, and during each timestep, vampires and humans move and interact with each other as well as with the objects on the map.
The core of the program is a loop that controls the duration of the simulation. It accepts three command line parameters: initial number of humans, initial number of vampires, and the number of timesteps. If no values are provided, reasonable defaults are used.
The program represents humans and vampires as objects. Humans have health and age variables, while vampires only have a health variable. They have various methods for actions like moving, attacking, and biting.
Humans start with a health of 100 and lose 1 health point for every step they take. They also have a random age between 10 and 50, increasing by 1 at each timestep. Humans cannot survive beyond 70 timesteps. Vampires begin with the same health they had as humans before turning, and they don't age. Their health decreases only if they are bitten by other vampires.
Food, water, and garlic can be represented as objects on the map, but it's not mandatory. The initial locations of these objects can be determined as desired.
In conclusion, this program simulates the spread of vampires on a 2D map in the African jungles. Humans are the primary targets of the vampires, who attempt to bite them and turn them into vampires. Vampire health decreases if they are bitten by other vampires. The presence of food, water, and garlic adds further interactions. The simulation runs for a specified number of timesteps, allowing humans, vampires, and objects to interact with each other.

SECTION-B Q3. Write a program for Sum () function that returns the sum of two positive numbers.
The program calculates the sum of two positive numbers entered by the user using the `Sum()` function in C++.
How can you write a program in C++ to calculate the sum of two positive numbers?Program in C++ that implements the `Sum()` function to calculate the sum of two positive numbers:
```cpp
#include <iostream>
int Sum(int a, int b) {
if (a < 0 || b < 0) {
// Handle invalid input (negative numbers)
return -1; // Return a special value to indicate an error
}
return a + b; // Calculate and return the sum
}
int main() {
int num1, num2;
std::cout << "Enter the first positive number: ";
std::cin >> num1;
std::cout << "Enter the second positive number: ";
std::cin >> num2;
int result = Sum(num1, num2);
if (result != -1) {
std::cout << "Sum: " << result << std::endl;
} else {
std::cout << "Invalid input! Both numbers should be positive." << std::endl;
}
return 0;
}
```
In this program, the `Sum()` function takes two integer parameters `a` and `b`. It first checks if either `a` or `b` is negative. If any of them is negative, it returns `-1` as a special value to indicate an error. Otherwise, it calculates the sum of `a` and `b` using the `+` operator and returns the result.
In the `main()` function, the user is prompted to enter two positive numbers. The `Sum()` function is then called with these numbers, and the result is displayed unless an error (-1) occurs due to negative input.

bubbleSort(arr, n);
cout << "\nSorted array: ";
for (int i = 0; i < n; i++) {
cout << arr[i] << " ";
}

The required calculations are shown below:i) First, find the differences in the length of the bar between each pair of temperatures as shown in the table below: ΔT(°C) ΔL(pulgadas) 10 0.02 20 0.03 30 0.05 Then, using AL = αATLO, we get α = ΔL/ATLOΔT, where AT is the temperature difference corresponding to ΔT. So, we have: ΔT(°C) ΔL(pulgadas) AT(°C) α 10 0.02 10 1.11E-05 20 0.03 20 1.11E-05 30 0.05 30 1.11E-05
The coefficient of thermal expansion of the steel is α = 1.11 x 10^-5 (in/°C) Uncertainty for the coefficient of thermal expansion: The uncertainty is given by the formula: (Δα/α) = sqrt[ (ΔL/L)^2 + (ΔT/ΔT)^2 ] The lengths given in the table are all given to two decimal places, so let's assume that the uncertainty is ±0.005 inches. The temperature differences are exact, so the uncertainty is zero. Therefore, we have: (Δα/α) = sqrt[ (0.005/239.99)^2 ] = 2.08 x 10^-5
= 0.00208% Correlation coefficient: Using the formula for the correlation coefficient, we get:
r = [nΣxy - (Σx)(Σy)] / sqrt[ (nΣx^2 - (Σx)^2)(nΣy^2 - (Σy)^2) ]
where n = 4 is the number of data points. The calculations are shown below: T (°C) L (pulgadas) xy 60 239.95 14397.0 70 239.97 16797.9 90 239.98 21598.2 100 240.00 24000.0 Σx = 320

Q3.4. Return the index of a specific product name using the Linear search algorithm ( 2 marks) Define a function named search prod, which must be able to search for a specific product name using the Linear search algorithm and return the relevant index number of the searched product name. The function must accept stock_list (of type list) and prod_name (of type str) as arguments. The specific product name (provided through prod_name) must be searched for in the prod_list (contained in the stock_list). Once found, the function must return the relevant index numbers using the variable named prod_index (of type tuple), i.e. prod_index = (index of stock_list, index of prod_list)
Here is the implementation of a Python function named `search_prod` which will use the linear search algorithm to find the index of a specific product name in the stock list:
```python def search_prod(stock_list, prod_name): prod_index = () for i in range(len(stock_list)): for j in range(len(stock_list[i]['prod_list'])): if stock_list[i]['prod_list'][j]['prod_name'] == prod_name: prod_index = (i, j) return prod_index return prod_index ```
The `search_prod` function accepts two arguments: `stock_list` (of type list) and `prod_name` (of type str). The function iterates through the `stock_list` using a nested loop to search for the product name.
Once it finds the product name, it returns the relevant index numbers using the variable named `prod_index` (of type tuple), i.e. `prod_index = (index of stock_list, index of prod_list)`.If the product name is not found in the `stock_list`, the function will return an empty tuple `()` indicating that the product name was not found.

dp and ip registers in 8086/8088 belong to
The DP and IP registers are essential for various memory and operational tasks, providing vital information for proper instruction execution and memory addressing in the microprocessor.
The DP (Data Pointer) and IP (Instruction Pointer) registers in the 8086/8088 microprocessors. These registers, which are located inside the microprocessor, serve as high-speed storage areas that allow for faster access compared to memory. The DP register, a 16-bit register, is responsible for calculating the physical addresses of data in memory. It points to the base address of the current segment or the extra segment's base address, and it contains both the offset address within the present segment and the base address of the current segment.
On the other hand, the IP register is also a 16-bit register and it holds the address of the next instruction to be executed by the microprocessor's Control Unit. This register plays a crucial role in program sequencing by indicating the memory location of the next instruction.
