Answer:

keylogger.

Explanation:

A keylogger can be defined as a software program or hardware device designed for monitoring and recording the keystrokes entered by an end user through the keyboard of a computer system or mobile device.

Basically, a keylogger can be installed as a software application or plugged into the USB port of a computer system, so as to illegally keep a record of all the inputs or keys pressed on a keyboard by an end user.

In order to prevent cyber hackers from gaining access to your keystrokes, you should install an anti-malware software application such as Avira, McAfee, Avast, Bitdefender, Kaspersky, etc.

An antivirus utility is a software application or program that's used to scan, detect, remove and prevent computer viruses such as Malware, Trojan horses, keyloggers, botnets, adwares etc.

In conclusion, a bot can use a keylogger to capture keystrokes on the infected machine to retrieve sensitive information.

Answer:

Explanation:

The following code is written in Java. It asks the user to enter a string. Then the program loops through the string and separates the string into an ArrayList of characters. Finally, it outputs each character separately on a its own line.

import java.util.ArrayList;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a String: ");

       String answer = in.nextLine();

       ArrayList<Character> charsList = new ArrayList<>();

       for (int i = 0; i < answer.length(); i++) {

           charsList.add(answer.charAt(i));

       }

       for (char x: charsList) {

           System.out.println(x);

       }

   }

}

But you can't use this device alone to connect two microphones to your USB C port and expect it to have usable volume. So the description is somewhat misleading ...

Answer:

Knowledge base.

Explanation:

Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.

Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.

Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;

I. Non-algorithmic processing.

II. Symbolic processing.

In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.

Hence, expert systems represents knowledge as a set of rules by mimicking the expertise of humans in a particular field to uniquely proffer solutions to a problem.

Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.

Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.

Basically, expert systems comprises five (5) main components and these are;

1. Explanation module.

2. Inference Engine.

3. Knowledge acquisition and learning module.

4. User Interface.

5. Knowledge Base.

In the context of the components that makes up an expert system, knowledge base is similar to a database because it is used for storing facts and figures, while keeping track of rules and explanations associated with facts. Thus, giving rise to the knowledge base management system (KBMS).

In the context of the components of a typical expert system, Knowledge base is similar to a database, but in addition to storing facts and figures, it keeps track of rules and explanations associated with facts.

An expert system is a form of artificial intelligence where computer imitate the decision making style of humans.

There are basically two types of the expert system and they are the inference engine and the knowledge base.

The knowledge base consists of the facts and rules and ways of interpreting them to arise to new insights. The inference engine applies logical rules to the knowledge base.

The synchronized keyword needs to be active on the hit method at any point where 2 or more threads (users) exists at any given moment. This is in order to prevent two or more users from trying to perform a hammer hit at the same time. This is what the synchronized keyword is used for. It prevents the more than one thread from calling the specific method at the same time. Instead it adds the action to a sequence so that the second thread calls the hit method only after the first thread's hit method finishes.

Explanation:

The newly created AVG column will contain the mean value of all 6 columns(P2010, P2011, P2012, P2013, 2014 and P2015) this means that we are taking the mean across the columns as our AVG column have the same length as the initial lengtb of the data Frame as all a values in each index are averaged to create the new column. To achieve this the value 1 will be passed to the axis argument in the apply method.

To drop the previous 6 columns, we se the axis argument set to 1, this will delete the columns passed to the drop method.

Hence, both x and y values of the axis argument will take the value 1.

"In inner for loop" is printed twice.

Answer: C. 2

Explanation:

Code:

int main()

{

   int limit = 0;

   for  (int i =0; i>=limit; i-=2) {

       for (int j = i; j <= 1; ++j){

           cout << "In inner for loop" << endl;

       }

       cout << "In outer for loop" << endl;

   }

   return 0;

}

Output:

In inner for loop

In inner for loop

In outer for loop

The output "In inner for loop" print twice.

Thus, option (c) is correct.

In the given code example, the inner for loop has a condition j <= 1.

This condition means that the loop will execute as long as j is less than or equal to 1.

However, the initial value of j is i, and the value of i decreases by 2 in each iteration of the outer for loop.

When i = 8, the inner loop has the condition j ≤ 1.

The loop will iterate as long as j is less than or equal to 1.

So the inner loop executes twice: once when j = 8, and then when j = 9. The statement "In inner for loop" prints twice.

Therefore, the output print twice.

Thus, option (c) is correct.

Answer: b

Explanation:

Program using linear recursion to duplicate items in a list:

def duplicate_list(lst):

   if not lst:

       return []

   else:

       return [lst[0], lst[0]] + duplicate_list(lst[1:])

# Example usage

user_input = input("Enter a list of items: ").split()

original_list = [item for item in user_input]

duplicated_list = duplicate_list(original_list)

print("Duplicated list:", duplicated_list)

By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.

Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

Explanation:

The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int count = 0;

       int highest, lowest;

       ArrayList<Integer> myArr = new ArrayList<>();

       while (true) {

           System.out.println("Enter a number [0-10] or -1 to exit");

           int num = in.nextInt();

           if (num != -1) {

               if ((num >= 0) && (num <= 10)) {

                   count+= 1;

                   myArr.add(num);

               } else {

                   System.out.println("Wrong Value");

               }

           } else {

               break;

           }

       }

       if (myArr.size() > 3) {

           highest = myArr.get(0);

           lowest = myArr.get(0);

           for (int x: myArr) {

               if (x > highest) {

Answer:

The answer is "Option b".

Explanation:

Function chaining is shown by this code, as the functions are called one after the other with one statement. Whenever you want to call a series of methods through an object, that technique is beneficial. Just because of that, you may give the same effect with less code and have a single given value only at top of the leash of operations.

Answer:

The updated program in C is as follows:

#include <stdio.h>

union myUnion{ char c; short s; int i; long l; };

int main(){

   union myUnion inputs;

   printf("Character: ");    scanf("%c", &inputs.c);

   printf("Output: %c", inputs.c);

   printf("\nShort: ");    scanf("%hd", &inputs.s);

   printf("Short: %hd", inputs.s);

   printf("\nInteger: ");    scanf("%d", &inputs.i);

   printf("Output: %d", inputs.i);

   printf("\nLong: ");    scanf("%ld", &inputs.l);

   printf("Long: %ld", inputs.l);

   return 0;

   }

The pseudocode is as follows:

Function union myUnion {

character; short; int; long

}

main() {

myUnion inputs;

Input inputs.c;  Print inputs.c

Input inputs.s; Print inputs.s

Input inputs.i; Print inputs.i;

Input inputs.l; Print inputs.l

}

Explanation:

This defines the union function

union myUnion{ char c; short s; int i; long l; };

The main begins here

int main(){

This calls the union function to main

   union myUnion inputs;

This prompts and gets input for character variable

   printf("Character: ");    scanf("%c", &inputs.c);

This prints the character input

   printf("Output: %c", inputs.c);

This prompts and gets input for short variable

   printf("\nShort: ");    scanf("%hd", &inputs.s);

This prints the short input

   printf("Short: %hd", inputs.s);

This prompts and gets input for integer variable

   printf("\nInteger: ");    scanf("%d", &inputs.i);

This prints the integer input

   printf("Output: %d", inputs.i);

This prompts and gets input for long variable

   printf("\nLong: ");    scanf("%ld", &inputs.l);

This prints the long input

   printf("Long: %ld", inputs.l);

   return 0;

   }

Variable "a" is declared as float

While p is declared as a pointer to an integer variable

An error of incompatible types will be returned on line 3, int *p = a;

Because the variables are not the same.

To assign a to p*, we have to use type casting.
