Answer:

breaking a problem into smaller parts

Explanation:

In language of computer science, decomposition is the process in which complex problems are divided into simpler parts. These simpler parts helps in the solving of the complex problems. They are made easier and comprehensible for the user to understand. Each simple part is further analyzed separately and the solution of the complex issues are derived.  The process becomes lengthy but the solution is found.

Explanation:

To prevent deadlock in the dining philosopher problem, resource allocation techniques can be employed, such as assigning a specific order for acquiring resources. This ensures that circular wait conditions are avoided, maintaining system stability.

Deadlock in the dining philosopher problem can be prevented using various techniques such as resource allocation, resource ordering, and deadlock avoidance. One commonly used approach is the resource allocation method, which involves assigning a specific order for resource acquisition to avoid circular wait conditions. Here's an illustration using pseudocode:

```

// Dining Philosopher Problem - Deadlock Prevention

const int N = 5  // Number of philosophers

enum {THINKING, HUNGRY, EATING} state[N]

Semaphore mutex = 1

Semaphore forks[N]

void philosopher(int i) {

   while (true) {

       think()

       pickup_forks(i)

       eat()

       putdown_forks(i)

   }

}

void pickup_forks(int i) {

   wait(mutex)

   state[i] = HUNGRY

   test(i)

   signal(mutex)

   wait(forks[i])

}

void putdown_forks(int i) {

   wait(mutex)

   state[i] = THINKING

   test((i + 1) % N)

   test((i + N - 1) % N)

   signal(mutex)

}

void test(int i) {

   if (state[i] == HUNGRY && state[(i + 1) % N] != EATING && state[(i + N - 1) % N] != EATING) {

       state[i] = EATING

       signal(forks[i])

   }

}

```

In the above pseudocode, the `test` function is used to check if a philosopher can start eating by ensuring that the adjacent philosophers are not eating. By controlling the resource allocation and the order in which the forks are acquired, we can prevent deadlock in the dining philosopher problem.

In this article, we will learn how to make a Hexagon using Turtle Graphics in Python. For that lets first know what is Turtle Graphics.

Turtle graphics

Turtle is a Python feature like a drawing board, which let us command a turtle to draw all over it! We can use many turtle functions which can move the turtle around. Turtle comes in the turtle library.The turtle module can be used in both object-oriented and procedure-oriented ways.

Some of the commonly used methods are:

forward(length): moves the pen in the forward direction by x unit.

backward(length): moves the pen in the backward direction by x unit.

right(angle): rotate the pen in the clockwise direction by an angle x.

left(angle): rotate the pen in the anticlockwise direction by an angle x.

penup(): stop drawing of the turtle pen.

pendown(): start drawing of the turtle pen.

Approach –

Define an instance for turtle.

For a hexagon execute a loop 6 times.

In every iteration move turtle 90 units forward and move it left 300 degrees.

This will make up Hexagon .

Below is the python implementation of above approach.

d. Test generators are faster than human testers

Explanation:

Test generators are automated testing applications used for testing by making use of artificial intelligence such as bots to take the place of actual users of the software or system to operate the software and detect bugs as well as other primary issues related to the functioning of the tested application

The test generators making use of automated testing are able to run through a developed application in much less time than human testers with the capability to give an analysis of the collected data

Test generators are however test generators are not adequate for carrying out a customer validation program which also include going over documentation and assessing product perception

Therefore, the correct option is test generators are more faster when testing than human testers.

Encryption applications use a complex mathematical algorithm to transform plain text into unreadable code, also known as ciphertext.

This process is called encryption, and it ensures that the information remains secure and private during transmission or storage. Encryption applications typically use a combination of keys and ciphers to scramble the text and prevent unauthorized access. Keys are secret codes that allow authorized users to decrypt the ciphertext and recover the original message. Ciphers, on the other hand, are algorithms that perform the actual encryption process. They manipulate the text by rearranging, substituting, or transforming its characters into a random sequence of numbers and letters. As a result, the ciphertext appears as gibberish to anyone who does not possess the right key to decrypt it. This way, encryption applications provide a high level of security to protect sensitive data from prying eyes or cyber attacks.

Event-based gateways are used in Business Process Model and Notation (BPMN) diagrams to show decision points in a process. They are represented by diamond shapes and can have various types, such as Exclusive, Inclusive, Parallel, and Complex.

Event-based XOR split is also known as deferred choice: This statement is true. An XOR split is used to create mutually exclusive paths in a process, meaning that only one of the outgoing paths can be taken. In an event-based XOR split, the decision on which path to take is deferred until an event occurs. For example, a customer may choose to pay for an order either by credit card or by bank transfer, and the decision on which payment method to use may be deferred until the customer actually makes the payment.

Event-based XOR split can only be followed by intermediate throwing events: This statement is false. An intermediate throwing event is an event that is triggered by an activity in the process, and it sends a signal to the event-based gateway to make a decision. However, an event-based XOR split can also be followed by other types of events, such as message events or timer events.

Explanation:

An instance of a derived class can be used in a program anywhere in that program that an instance of a base class is required. 1. True

An instance of a derived class can indeed be used in a program anywhere that an instance of a base class is required. This is a fundamental concept in object-oriented programming known as polymorphism.

Polymorphism allows objects of different classes to be treated as objects of the same base class, enabling code reuse, flexibility, and extensibility.

Inheritance is a key mechanism in object-oriented programming, where a derived class inherits the properties and behaviors of a base class. By using inheritance, we can create a hierarchy of classes, with the derived class inheriting the characteristics of the base class while adding its own unique features.

When a function takes an instance of a base class as a parameter, it can also accept an instance of any derived class that inherits from the base class. This is because the derived class is a specialization of the base class and includes all its functionality. The function can work with the base class methods and data members and can also access the additional methods and data members specific to the derived class.

This concept of substitutability allows for code reuse and promotes flexibility and scalability in software development. It enables us to write code that operates on a generic base class, which can later be extended by deriving new classes with specialized behaviors. This way, we can write more generic and modular code that can accommodate future enhancements without modifying existing code.
