Implement in C only Write a function named ‘sWiTcHcAsE()’ that
takes in a string as its only argument. The function should modify
the incoming string so that any lowercase letters become uppercase
Here is a possible solution in C language to write a function named `sWiTcHcAsE()` that takes in a string as its only argument and modifies the incoming string so that any lowercase letters become uppercase:
void sWiTcHcAsE(char *str) {
int i = 0;
while (str[i]) { // Iterate over all characters in the string
if (str[i] >= 'a' && str[i] <= 'z') { // If the character is a lowercase letter
str[i] = str[i] - 'a' + 'A'; // Convert it to uppercase
}
i++; // Move to the next character
}
}
This function modifies the incoming string by converting any lowercase letters to uppercase.
The function iterates over all characters in the string and checks if each character is a lowercase letter.
If it is, the function converts it to uppercase by subtracting the ASCII value of 'a' and adding the ASCII value of 'A'.
This operation takes advantage of the fact that the ASCII values of uppercase letters are consecutive and higher than the ASCII values of lowercase letters.
Once all characters have been checked, the function returns and the string is modified.

Given a class City, with a public accessor method public String getName() and a different class containing a populated list of City objects public class Something private LinkedList coastal Towns: /* Constructor not shown / public boolean iaSortedByName() { /*Write this code */) } write the method is SortedByName() which returns true if the list coastalTowns is sorted in ascending order by city name and false otherwise. The list coastalTowns should not be altered in any way during this process.
The method isSortedByName() that returns true if the list coastalTowns is sorted in ascending order by city name and false otherwise.
The list coastalTowns should not be altered in any way during this process:
public boolean isSortedByName() {
if (coastalTowns.size() <= 1) {
return true;
}
Iterator<City> iter = coastalTowns.iterator();
City current = iter.next();
while (iter.hasNext()) {
City next = iter.next();
if (current.getName().compareTo(next.getName()) > 0) {
return false;
}
current = next;
}
return true;
}
The method first checks if the size of the list is less than or equal to 1, in which case it is considered sorted. If the list has more than one element, it uses an iterator to traverse the list and compare adjacent elements. If the name of the current element is greater than the name of the next element, then the list is not sorted and the method returns false. If the entire list is traversed without finding any out-of-order elements, then the method returns true.
Note that the method assumes that the City class has a public accessor method called getName() that returns the name of the city as a String. The method also assumes that the list coastalTowns is an instance of LinkedList<City> that has already been populated with City objects.

Question 1. Authentication Protocol (30 marks) Max length: Two A4 pages including all diagrams. Text in the diagram must at least be 11 points Font size: 11 or 12 points. Line spacing: \( 1.5 \) lines
An authentication protocol is a mechanism used to verify the identity of users in a system. The protocol includes multiple steps to ensure secure authentication and protect against unauthorized access.
An authentication protocol is crucial for ensuring the security of a system by verifying the identity of users. One commonly used authentication protocol is the challenge-response protocol. In this protocol, the server generates a random challenge and sends it to the client. The client then encrypts the challenge using a shared secret key and returns the encrypted challenge to the server. The server decrypts the response using the same secret key and compares it with the original challenge. If the two match, the user is authenticated.
Another commonly used protocol is the password-based authentication protocol. In this protocol, the user provides a username and password. The server verifies the entered credentials against the stored credentials in its database. If they match, the user is authenticated. To enhance security, passwords are often stored as hash values in the server's database, making it difficult for an attacker to retrieve the original password.
There are also more advanced authentication protocols available, such as biometric-based authentication, two-factor authentication (2FA), and multi-factor authentication (MFA). Biometric-based authentication uses unique biological traits like fingerprints or facial recognition to verify the user's identity. 2FA and MFA involve combining multiple authentication factors, such as passwords and SMS codes, to provide an additional layer of security.
In conclusion, an authentication protocol is a crucial component of any secure system. It ensures that only authorized users can access sensitive information or perform specific actions. By implementing appropriate authentication protocols, organizations can safeguard their systems against unauthorized access and protect user data.

How is new operator different than malloc? (2 marks)
What is the difference between function overloading and operator
overloading? (2 marks)
Difference between new operator and malloc: Memory Allocation, Type Safety, Constructor Invocation, Return Type, Error Handling:.
Memory Allocation: The new operator is used in C++ to dynamically allocate memory for objects, while malloc is a function in C used for dynamic memory allocation.
Type Safety: The new operator ensures type safety by automatically determining the size of the object based on its data type, while malloc requires manual specification of the size in bytes.
Constructor Invocation: When using new, the constructor of the object is called to initialize its state, whereas malloc does not invoke any constructor. This allows new to handle complex objects with constructors and destructors, while malloc is suitable for allocating raw memory.
Return Type: The new operator returns a pointer to the allocated object, automatically casting it to the appropriate type. malloc returns a void* pointer, requiring explicit casting to the desired type.
Error Handling: If the new operator fails to allocate memory, it throws an exception (std::bad_alloc), whereas malloc returns NULL if it fails to allocate memory.
Difference between function overloading and operator overloading:
Function Overloading: It allows multiple functions with the same name but different parameters in a class or namespace. The compiler differentiates between these functions based on the number, types, or order of the parameters. Function overloading provides flexibility and code reusability by allowing similar operations to be performed on different data types or with different argument combinations.
Operator Overloading: It enables operators such as +, -, *, /, etc., to be redefined for custom types. It allows objects of a class to behave like built-in types with respect to operators. Operator overloading is achieved by defining member functions or global functions with the operator keyword followed by the operator symbol. It provides a concise and intuitive way to work with objects, enabling natural syntax for custom operations.
In summary, function overloading is used to define multiple functions with the same name but different parameters, while operator overloading allows custom types to redefine the behavior of operators.

An Ethernet frame with a destination address of 25:00:C7:6F:DA:41 is a unicast. Unicast is a type of communication where data is sent from one host to another host on a network, where the destination host receives the information, and no other hosts receive the information.
Each network device has a unique address, which is used to direct traffic to the correct destination. In Ethernet, the 48-bit MAC (Media Access Control) address is used for this purpose. The first half of the MAC address is the OUI (Organizationally Unique Identifier), which identifies the vendor that produced the device, while the second half is the NIC (Network Interface Controller) identifier, which is unique for every device produced by the vendor.
The term broadcast means that data is sent from one host to all other hosts on the network. In contrast, multicast refers to a type of communication where data is sent to a group of devices that are specifically identified as receivers of the data. Simulcast is a term that refers to the simultaneous broadcast of the same content over multiple channels or networks.

A class C IP address 206.12.1.0 is given with 29 subnets. What is the subnet mask for the maximum number of hosts? How many hosts can each subnet have? What is the IP address of host 3 on subnet 6
To find the IP address of host 3, we add 2 to the network address ( since the first two addresse in each subnet are reserved for the network and broadcast addresses ) and multiply by the number of the subnet (since host 3 is on subnet.
Subnet Mask:
The subnet mask for the maximum number of hosts for 29 subnets can be found using the formula:
2^n - 2 = number of hosts (n = number of bits used for subnetting)
For 29 subnets:
2^5 = 32 - 2 = 30
Thus, the subnet mask is /27.
Hosts per Subnet:
To find the number of hosts each subnet can have, we use the same formula:
2^n - 2 = number of hosts (n = number of bits used for host addressing)
In this case, 3 bits are used for subnetting, leaving 5 bits for host addressing:
2^5 - 2 = 30
Thus, each subnet can have 30 hosts.
IP address of host 3 on subnet 6:
To find the IP address of host 3 on subnet 6, we need to know the network address for subnet 6. Since we are given the Class C IP address and the subnet mask, we can calculate the network address using binary AND:
IP Address: 11001110.00001100.00000001.00000000
Subnet Mask: 11111111.11111111.11111111.11100000
AND: 11001110.00001100.00000001.00000000
& 11111111.11111111.11111111.11100000
= 11001110.00001100.00000001.00000000
Network Address: 206.12.1.0
Network Address: 206.12.1.0
Subnet Number: 6
Add 2: 206.12.1.2
Multiply by 6: 206.12.6.18

3. Discuss your solution to the inverse kinematic problem in terms of redundancy, degeneracy and uniqueness.
4. Determine the expression for the velocity of the end effector.
5. Determine the expressions for the joint velocities.
1. The forward kinematic transform for the manipulator involves determining the position and orientation of the end-effector based on the joint angles. It includes calculating the transformation matrix that relates the joint variables to the end-effector's position and orientation in the workspace.
2. The inverse kinematic transform for the manipulator involves finding the joint angles that correspond to a desired position and orientation of the end-effector. In this case, using Px and Py as the set positions for the end-effector, the inverse kinematics solution will calculate the corresponding joint angles that achieve this position.
3. The solution to the inverse kinematic problem can involve issues of redundancy, degeneracy, and uniqueness. Redundancy refers to the existence of multiple joint configurations that achieve the same end-effector position. Degeneracy occurs when certain joint configurations result in limited or constrained motion of the end-effector. Uniqueness refers to the presence or absence of a single solution for a given set of desired end-effector positions.
4. The expression for the velocity of the end effector involves calculating the rate of change of the end-effector's position and orientation with respect to time. It can be derived using the Jacobian matrix, which relates the joint velocities to the end-effector velocity.
5. The expressions for the joint velocities are derived from the velocity of the end effector and the Jacobian matrix. By multiplying the inverse of the Jacobian matrix with the end-effector velocity, we can determine the joint velocities that result in the desired end-effector motion.
In conclusion, the forward kinematic transform determines the end-effector position based on joint angles, while the inverse kinematic transform finds the joint angles for a desired end-effector position.

For this assignment, you will obtain current yields for Treasury securities at a variety of maturities, calculate the forward rates at various points in time, and graph the yield and forward rate curves. As you collect data, format your spreadsheet appropriately. Collect the data from https://www.wsj.com/market-data/bonds/treasuries. You will notice two links on this page: one for "Treasury Notes \& Bonds," and the other for "Treasury Bills." A bill is a short-term debt instrument with maturities up to fifty-two weeks, notes have maturities between two and ten years, while bonds have maturities up to thirty years. Pick a day to start the assignment and label that date "Today" in your spreadsheet. Then, obtain the Asked Yield from the WSJ at the following intervals from your start date: 1-, 3-, and 6-months, and 1-, 3-, 5-, 7-, 10-, 15-, 20-, 25-, and 30-years. For maturities up to 1-year, use yields for T-bills. Do not worry if you do not find securities with maturity dates at exact intervals from your start date; this is expected. For example, if my start date is 8/1/2022, the closest security I may find for a 6-month T-bill might mature on 1/31/23. If there is more than one security for each maturity, choose one; the yields will be very close or the same. Use the YEARFRACO function to calculate the time to maturity for each security, with a start_date of the date you picked for Today (above) and an end_date of the maturity date. Then, calculate the forward rates between each maturity. The time between each pair of securities is t in the root, 1/t, you'll take to compute the forward rates. Finally, graph the yield and forward rate curves and appropriately label your chart. Time to maturity should be on the x-axis and Yield to maturity on the y-axis.
To complete the assignment, you need to collect current yields for Treasury securities at various maturities, calculate forward rates at different points in time, and graph the yield and forward rate curves.
In this assignment, you are required to gather current yields for Treasury securities at different maturities and calculate forward rates. Treasury bills, notes, and bonds are the three types of securities considered. Treasury bills have maturities up to fifty-two weeks, notes have maturities ranging from two to ten years, and bonds have maturities up to thirty years.
To begin, select a specific day as the starting point and label it "Today" in your spreadsheet. and collect the Asked Yield at specific intervals from your start date. These intervals include 1-, 3-, and 6-months, as well as 1-, 3-, 5-, 7-, 10-, 15-, 20-, 25-, and 30-years. For maturities up to 1-year, use the yields for T-bills.
If you cannot find securities with exact maturity dates corresponding to your start date, it is acceptable to select the closest available security. Remember that if there are multiple securities for each maturity, you can choose any of them since their yields will be very close or identical.
Next, use the YEARFRACO function in your spreadsheet to calculate the time to maturity for each security. Set the start_date as the "Today" date you labeled, and the end_date as the maturity date of each security. With these time to maturity values, you can then calculate the forward rates between each pair of securities. The time between each pair, denoted as "t" in the root formula, is obtained as 1/t to compute the forward rates accurately.
Finally, create a graph of the yield and forward rate curves. The x-axis should represent the time to maturity, while the y-axis should represent the yield to maturity. Be sure to label your chart appropriately for clarity.

what protocol is used to request a mac address that corresponds to a known ipv4 address on the local network?
The protocol that is used to request a MAC address that corresponds to a known IPv4 address on the local network is ARP (Address Resolution Protocol). ARP is a protocol used for mapping a physical device’s MAC address to its IP address, which is assigned to it by the Internet Protocol (IP).
ARP operates in Layer 2 of the OSI model or Data Link Layer.ARP is a stateless protocol, which implies that an ARP request should be sent every time a MAC address is required, as it does not store or maintain a database of IP-MAC addresses like DNS servers. ARP is important for communication within the same network because devices in a network can directly communicate with one another, but they are unable to communicate with devices in other networks without the help of a router.When a computer wants to send data to another device on the local network, it requires the MAC address of the target device. It uses ARP to resolve the IP address of the target device to its corresponding MAC address. ARP generates a broadcast message on the network when it needs to find out the MAC address of a specific IP address.
The computer sends an ARP request in broadcast mode to the local network. Every device on the network receives this broadcast, but only the device that is assigned the IP address that the computer is trying to reach will respond with its MAC address. The requesting computer then utilizes the MAC address it obtained from the ARP response to communicate with the target device.

pattern applied to S1, S0, D3, D2, D1, and D0: a) 110101
b) 011010 c) 101011 d) 001101
The output Y of the 4-bit barrel shifter for the given bit patterns are: a) 1011, b) 0011, c) 0101, d) 0011.
To find the output Y of the 4-bit barrel shifter for each given bit pattern, we will analyze the truth table of the barrel shifter as shown in Figure-9. The barrel shifter has two control inputs (S1 and S0) and four data inputs (D3, D2, D1, D0), where D3 is the most significant bit and D0 is the least significant bit. The output Y will depend on the combination of the control inputs and data inputs.
Let's evaluate the output Y for each given bit pattern:
a) Bit pattern: 110101
S1 = 1, S0 = 1
The control inputs S1 and S0 indicate that a left rotation is required.
The data inputs D3, D2, D1, D0 are 1101.
After the left rotation, the output Y will be 1011.
Therefore, for the given bit pattern, the output Y is 1011.
b) Bit pattern: 011010
S1 = 0, S0 = 1
The control inputs S1 and S0 indicate that a right rotation is required.
The data inputs D3, D2, D1, D0 are 0110.
After the right rotation, the output Y will be 0011.
Therefore, for the given bit pattern, the output Y is 0011.
c) Bit pattern: 101011
S1 = 1, S0 = 0
The control inputs S1 and S0 indicate that a logical shift left is required.
The data inputs D3, D2, D1, D0 are 1010.
After the logical shift left, the output Y will be 0101.
Therefore, for the given bit pattern, the output Y is 0101.
d) Bit pattern: 001101
S1 = 0, S0 = 0
The control inputs S1 and S0 indicate that no shift or rotation is required.
The data inputs D3, D2, D1, D0 are 0011.
Since no shift is performed, the output Y will be the same as the input.
Therefore, for the given bit pattern, the output Y is 0011.
In summary:
a) Output Y = 1011
b) Output Y = 0011
c) Output Y = 0101
d) Output Y = 0011
These results are obtained by analyzing the control inputs S1 and S0 to determine the type of shift or rotation required, and then applying the corresponding operation to the data inputs. The output Y represents the shifted or rotated version of the input data.

Write a structural module to compute the logic function, y = ab’ + b’c’+a’bc, using multiplexer logic. Use a 8:1 multiplexer with inputs S2:0, d0, d1, d2, d3, d4, d5, d6, d7, and output y.
The structural module utilizes the multiplexer's select lines and inputs to efficiently compute the desired logic function, providing a compact and streamlined solution.
How does the structural module using an 8:1 multiplexer simplify the computation of the logic function?
To implement the logic function y = ab' + b'c' + a'bc using a multiplexer, we can design a structural module that utilizes an 8:1 multiplexer. The module will have three select lines, S2, S1, and S0, along with eight data inputs d0, d1, d2, d3, d4, d5, d6, and d7. The output y will be generated by the selected input of the multiplexer.
In order to compute the logic function, we need to configure the multiplexer inputs and select lines accordingly. We assign the input a to d0, b to d1, c' to d2, a' to d3, b' to d4, and c to d5. The remaining inputs d6 and d7 can be assigned to logic 0 or logic 1 depending on the desired output for the unused combinations of select lines.
To compute the logic function y, we set the select lines as follows: S2 = a, S1 = b, and S0 = c. The multiplexer will then select the appropriate input based on the values of a, b, and c. By configuring the multiplexer in this way, we can obtain the desired output y = ab' + b'c' + a'bc.
Overall, the structural module using an 8:1 multiplexer provides a compact and efficient solution for computing the logic function y. It simplifies the implementation by leveraging the multiplexer's capability to select inputs based on the select lines, enabling us to express complex logical expressions using a single component.

Propagation Delay between FM radio and Satellite radio 1. Turn on a radio on FM mode, Saudi Quran Broadcast. 2. Turn on the same channel on a satellite TV. 3. Which one is leading? 4. Why? 5. Approxim
The given scenario involves comparing the propagation delay between FM radio and satellite radio for a specific channel. The objective is to determine which signal is leading and provide an explanation for the observed result.
To compare the propagation delay between FM radio and satellite radio, follow these steps:
1. Turn on a radio on FM mode and tune in to the Saudi Quran Broadcast channel.
2. Turn on the same channel on a satellite TV receiver.
3. Observe which signal is leading, i.e., which signal reaches your location first.
The leading signal is typically the FM radio signal. This is because FM radio signals travel through the Earth's atmosphere directly, while satellite radio signals need to be transmitted to a satellite in space and then retransmitted back to Earth. The additional distance traveled by satellite radio signals introduces a delay, resulting in the FM radio signal arriving earlier.
By conducting the experiment and comparing the FM radio and satellite radio signals, we can observe that the FM radio signal typically reaches the location first. This is due to the shorter propagation path of FM radio signals compared to satellite radio signals, which have to travel to and from a satellite in space. The approximate delay between the two signals depends on factors such as the distance to the satellite and the specific broadcasting equipment used.
