(C)  to locate modem tones. The right response is c. Finding the modem tones that computers and other devices use to connect over a phone line is a technique known as wardialing.

In order to find a suitable target, the technique includes dialling a variety of phone numbers and listening for the sound of a modem tone. Security experts and hackers have in the past utilised wardialing to find weak computer systems connected to phone lines. However, it is illegal and unethical to utilise it for evil intent. It's not frequently used to find other hackers online, by telemarketers to contact phone numbers automatically, or to launch a brute force attack.

It calculates the probabilities and statistical measures for the given random variable X with the specified probability mass function.

Here's a summary of the solution:

I. Probability Mass Function:

The probability mass function (PMF) for X is:

\(P(x) 0 0.1 0.7 0.2\)

X     1   2    3   4

a.\(P(X ≤ 3.5) = P(1 ≤ X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3) = 0.1 + 0.7 + 0.2 = 1.0\)

b. \(P(X > 5) = P(X = 6) + P(X = 7) = 0.2\)

c. \(P(X ≤ 5.2) = P(X ≤ 5) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.1 + 0.7 + 0.2 = 1.0\)

d. \(P(X > 7) = 0\)

e. \(P(1 ≤ X ≤ 2) = P(X = 1) + P(X = 2) = 0.1 + 0.7 = 0.8\)

f. \(P(X < 2) = P(X = 1) = 0.1\)

g. \(P(X = 2) = 0.7\)

h.\(P(X ≤ 2) = P(X = 1) + P(X = 2) = 0.1 + 0.7 = 0.8\)

II. Mean and Variance of X:

The mean (expected value) of X is calculated as:

\(µ = Σx * P(x) = 1 * 0.1 + 2 * 0.7 + 3 * 0.2 + 4 * 0.0 = 2.1\)

The variance of X is calculated as:

\(σ² = Σ(x - µ)² * P(x) = (1 - 2.1)² * 0.1 + (2 - 2.1)² * 0.7 + (3 - 2.1)² * 0.2 + (4 - 2.1)² * 0.0 = 0.49 + 0.07 + 0.16 + 0.49 = 1.21\)

Therefore, the PMF, probabilities, mean (expected value), and variance of the random variable.

2. 25.

3. POP.

4. IMAP.

5. POP.

6. POP.

7. 110.

8. IMAP-capable server.

Explanation:

The application layer process that sends mail uses Simple Mail Transfer Protocol (SMTP). When a client sends email, the client process connects with a server process on well-known port 25. A client retrieves email, however, using one of two application layer protocols: Post Office Protocol (POP) or Internet Message Access Protocol (IMAP). With POP, mail is downloaded from the server to the client and then deleted on the server. The server starts the POP service by passively listening on TCP port 110 for client connection requests. However, when a client connects to a server running IMAP, copies of the messages are downloaded to the client applications. The original messages are kept on the server until they are manually deleted.

The false statement about operator overloading is that you can overload all C++ operators to be used with class objects.

Operator overloading is the process of enabling C++'s operators to work with class objects. It is also defined as the process of providing special meanings to operators used in the program, thereby, they are redefined to perform the desired operations on user-defined data types.

By overloading the operators, it is possible to implement the operator’s functionality in different ways.

C++ overloads the addition operator (+) and the subtraction operator (-) to perform differently, depending on their context in integer, floating-point and pointer arithmetic with data of fundamental types. For example, if we have two objects of the same class, we can overload the operator “+” to add the two objects and return the resultant object.

Overloading of operators helps in reducing the lines of codes and makes the program easy to understand. It is essential to note that there are a few operators that cannot be overloaded. Some of these operators are the dot (.) operator, the ternary conditional operator (? :), the sizeof operator, the comma operator, and the scope resolution operator (::).

Thus, statement c is incorrect. You cannot overload all C++ operators to be used with class objects.

The program uses the Pthread library to create multiple threads, each executing the Simple Thread function, and modifies a shared variable.

Sure! Here's an example of a C program that uses the Pthread library to spawn multiple threads and execute the Simple Thread function:

#include <stdio.h>

#include <stdlib.h>

#include <pthread.h>

#include <unistd.h>

int SharedVariable = 0;

void SimpleThread(int which) {

   int num, val = 0;

   for (num = 0; num < 20; num++) {

       if (random() > RAND_MAX / 2)

           usleep(10);

       val = SharedVariable;

       printf("*** thread %d sees value %d\n", which, val);

       SharedVariable = val + 1;

   }

   val = SharedVariable;

   printf("Thread %d sees final value %d\n", which, val);

}

int main(int argc, char* argv[]) {

   if (argc != 2) {

       printf("Usage: %s <num_threads>\n", argv[0]);

       return 1;

   }

   int numThreads = atoi(argv[1]);

   if (numThreads <= 0) {

       printf("Invalid number of threads\n");

       return 1;

   }

   pthread_t threads[numThreads];

   int i;

   for (i = 0; i < numThreads; i++) {

       if (pthread_create(&threads[i], NULL, (void*)SimpleThread, (void*)i) != 0) {

           printf("Failed to create thread %d\n", i);

           return 1;

       }

   }

   for (i = 0; i < numThreads; i++) {

       pthread_join(threads[i], NULL);

   }

   return 0;

}

This program takes a command line parameter indicating the number of threads to create. It validates the input to ensure it is a valid number. It then creates the specified number of threads, each executing the Simple Thread function. The shared variable Shared Variable is modified and printed within the loop of each thread.

Based on the information, it should be noted that the diagram is a parallel Circuit.

A series circuit is an electrical circuit where the components, such as resistors, capacitors, and inductors, are connected one after the other in a single path, so that the same current flows through each component. If one component fails or is disconnected, the entire circuit will be broken, and no current will flow

The amount of current flowing through each component in a series circuit is the same. In contrast, the components in parallel circuits are arranged in parallel with one another, which causes the circuit to divide the current flow. This is shown in the diagram.
