Answer:

19.9 pF

Explanation:

Given that:

Series connection :

11pF and 21pF

C1 = 11pF ; C2 = 21pF

Cseries = (C1*C2)/ C1 + C2

Cseries = (11 * 21) / (11 + 21)

Cseries = 7.21875 pF

C1 = 22pF ; C2 = 30pF

Cseries = (C1*C2)/ C1 + C2

Cseries = (22 * 30) / (22 + 30)

Cseries = 12.6923 pF

Equivalent capacitance is in parallel, thus,

7.21875pF + 12.6923 pF = 19.91105 pF

= 19.9 pF

Here is the JAVA program:

public class StudentDerivationFromPerson  {

public static void main (String [] args) { //start of main function

StudentData courseStudent = new StudentData(); //creates an object of StudentData class named courseStudent

     courseStudent.setName("Smith"); //assign courseStudent's name with Smith using courseStudent object and by calling the mutator method setName

     courseStudent.setAge(20); //assign courseStudent's age with 20 using courseStudent object and by calling the mutator method setAge

     courseStudent.setID(9999); //assign courseStudent's ID with 9999 using courseStudent object and by calling the mutator method setID

     courseStudent.printAll(); //calls printAll member method using courseStudent object. This will print the name and age

     System.out.println(", ID: " + courseStudent.getID()); //println statement to print the ID by calling accessor method getID of StudentData class

return;}}

Explanation:

Here is the complete program:

PersonData.java

public class PersonData {

private int ageYears;

private String lastName;

public void setName(String userName) {

lastName = userName;

return; }  

public void setAge(int numYears) {

ageYears = numYears;

return; }  

public void printAll() {

System.out.print("Name: " + lastName);

System.out.print(", Age: " + ageYears);

return; }}

StudentData.java

public class StudentData extends PersonData {

private int idNum;  

public void setID(int studentId) {

idNum = studentId;

return; }  

public int getID() {

return idNum; } }

StudentDerivationFromPerson.java

public class StudentDerivationFromPerson  {

public static void main (String [] args) {

StudentData courseStudent = new StudentData();

     courseStudent.setName("Smith");

     courseStudent.setAge(20);

     courseStudent.setID(9999);

     courseStudent.printAll();

     System.out.println(", ID: " + courseStudent.getID());

return;}}

Here the courseStudent is the object of class StudentData

new keyword is used to create and object of a class

This object is used to access the methods of class

Note that the StudentData class is the sub class of PersonData class

The object courseStudent first accesses the mutator method setName of class PersonData to set the name (lastName) as Smith.

Next it accesses the mutator method setAge of class PersonData to set the age (ageYears) to 20

Then courseStudent accesses the mutator method setID of class StudentData to set the ID (idNum) to 9999.

Then the method printAll() of PersonData class is called using courseStudent object. This method has two print statements i.e.

System.out.print("Name: " + lastName);

System.out.print(", Age: " + ageYears);

So these two statement are printed on the output screen. They display the name and age i.e. Smith and 20 with a comma between them.

Next we have to display the ID too so we use this statement:

System.out.println(", ID: " + courseStudent.getID());

The above print statement calls getID accessor method of StudentData class  to get the ID and display it on the screen.

Hence the output of the above program is:

Name: Smith, Age: 20, ID: 9999

Answer:

The emergence of computers from 1936-1985 witnessed several remarkable trends that had considerable relevance to the education industry in Nigeria. Below are some of the significant trends and their relevance to the education sector in Nigeria:

1) The First Generation Computers (1936-1950s): The first computers were large, bulky, and crude devices that used vacuum tubes, magnetic drums, and punched cards for data processing. The early computers were mainly used for government and military purposes, such as code-breaking, ballistic calculations, and scientific research. The relevance of first-generation computers to the education industry in Nigeria was limited, as they were too expensive and complex for widespread adoption in schools.

2) The Second Generation Computers (1950s-1960s): In the 1950s, computers became smaller, faster, and more reliable, thanks to the invention of transistors. Second-generation computers used magnetic core memory and high-level programming languages such as COBOL and FORTRAN. These advancements made computers more accessible to businesses and government agencies, enabling them to streamline their operations and increase efficiency. However, the education industry in Nigeria still had limited access to computers due to cost and technological barriers.

3) The Third Generation Computers (1960s-1970s): The Third Generation Computers witnessed several improvements in technology, such as the development of the integrated circuit, which led to the creation of miniaturized and affordable computers. These computers were faster, more reliable, and had increased data storage capacity. They were also equipped with graphical user interfaces and interactive software, making them more user-friendly. This generation of computers became more relevant to the education industry in Nigeria, as they were affordable enough to be used in schools for teaching and learning.

4) The Fourth Generation Computers (1970s-1980s): Fourth-generation computers were faster, cheaper, and more efficient than their predecessors. The introduction of microprocessors made it possible to design computers that were small enough to fit on a desktop. This development led to the development of personal computers, which revolutionized the way people worked and communicated. Personal computers had enormous relevance to the education industry in Nigeria, as they enabled students and teachers to access information and learn new skills more easily.

In conclusion, the trends in the emergence of computers from 1936-1985 had considerable relevance to the education industry in Nigeria. Despite the technological and cost barriers that limited access to computers in the early years, the advancement of computer technology over time made it possible for computers to become an integral part of teaching and learning in Nigeria.

The first blank refers to "White-box testing", the second blank refers to "Black-box testing", the third blank refers to "Functional testing", the fourth blank refers to "Test automation framework", and the fifth blank refers to "Regression testing".

Code-based testing involves analyzing the code structure and the logic of the program to determine the most effective test cases. This method can include structural, functional, and white-box testing techniques. On the other hand, data-based testing is concerned with examining the data that is flowing in and out of the system, as well as examining logs to ensure that the data is being processed as expected. Input-output testing, also known as black-box testing, checks that the system behaves correctly with various inputs, without regard to the code. A framework for automating tests is a software tool that provides a pre-designed structure for writing, executing, and maintaining test cases. Regression testing involves rerunning test cases that have been run before to ensure that changes made to the system do not break previously working functionality.

The showInputDialog method is a part of the JOptionPane class in Java Swing, which provides a set of pre-built dialog boxes for displaying messages and obtaining user input.

Here's an example of how you can declare an array to store objects of a class, and use a method from the JOptionPane class to request the length of the array from the user:

import javax.swing.JOptionPane;

public class MyClass {

   // Define your class according to the UML

   public static void main(String[] args) {

       // Request the length of the array from the user using JOptionPane

       String lengthInput = JOptionPane.showInputDialog("Enter the length of the array:");

       // Parse the user input to an integer

       int arrayLength = Integer.parseInt(lengthInput);

       // Declare the array to store objects of the class

       MyClass[] myArray = new MyClass[arrayLength];

       // Now you have an array of the desired length to store objects of your class

       // You can proceed to instantiate objects and store them in the array

   }

}

In this example, we use the showInputDialog method from the JOptionPane class to display an input dialog box and prompt the user to enter the desired length of the array. The user's input is then parsed into an integer using Integer.parseInt() and stored in the arrayLength variable.

Therefore, an array myArray of type MyClass is declared with the specified length, ready to store objects of the MyClass class.

The actions that might occur when transforming data are to recognize relationships in your data, make calculations based on your data and identify a pattern in your data. Data transformation is the process of changing the format, organization, or values of data.

In the data pipeline, there are two places where data can be changed for projects like data analytics. The middle step of an ETL (extract, transform, load) process, which is frequently employed by companies with on-premises data warehouses, is data transformation.

Most firms today use cloud-based data warehouses, which increase compute and storage capacity with latency measured in seconds or minutes. Due to the scalability of the cloud platform, organizations can load raw data into the data warehouse without any transformations; this is known as the ELT paradigm ( extract, load, transform).

Data integration, data migration, data warehousing, and data wrangling are all processes that may include data transformation.

a) Lowest address: 0, Highest address: (2^20) - 1. b) Lowest address: 0, Highest address: ((2^20) / 2) - 1. c) Lowest address: 0, Highest address: ((2^20) / 4) - 1.

a) If memory is byte-addressable, the lowest address would be 0 and the highest address would be (2^20) - 1.

This is because each byte in the memory requires a unique address, and since there are 2^20 bytes in total, the highest address would be one less than the total number of bytes.

b) If memory is word-addressable with a 16-bit word, each word would consist of 2 bytes.

Therefore, the lowest address would be 0 (representing the first word), and the highest address would be ((2^20) / 2) - 1.

This is because the total number of words is equal to the total number of bytes divided by 2.

Subtracting 1 gives us the highest address, as the addresses are zero-based.

c) If memory is word-addressable with a 32-bit word, each word would consist of 4 bytes.

In this case, the lowest address would still be 0 (representing the first word), and the highest address would be ((2^20) / 4) - 1.

Similar to the previous case, the total number of words is equal to the total number of bytes divided by 4.

Subtracting 1 gives us the highest address.

Some examples of access control systems are: Card-based access control systems, Biometric access control systems, Keypad access control systems, Proximity access control systems

Access control systems are used to limit or control access to certain areas or resources by determining who or what is authorized to enter or exit. In modern-day society, access control systems are widely used in both commercial and residential settings to enhance security and safety. Some examples of access control systems are discussed below.

1. Card-based access control systems- These are the most common types of access control systems. In card-based systems, authorized personnel are issued an access card that contains a unique code or number. When the person swipes the card through a reader, the system checks if the card is valid and then unlocks the door.

2. Biometric access control systems- In this system, the user's unique physical characteristics are used to identify them, such as fingerprints, voice, face, or retina scans. Biometric systems are highly accurate and provide enhanced security.

3. Keypad access control systems- Keypad systems use a secret code entered through a keypad. The code can be changed frequently to prevent unauthorized access.

4. Proximity access control systems- Proximity systems use a small chip or key fob that emits a radio signal to a reader mounted near the door. When the signal is received, the door unlocks. These are just a few examples of access control systems. There are other systems like security guards, smart cards, RFID-based systems, and more.
