Explanation:

SSUDUDUDIDJE

Answer:

a. Microphone

d. Wi-Fi antenna

Explanation:

The wifi antenna , is present in the screen bezel , and the two cables are connected to the motherboard and the wifi adapter .

Hence , we need to be aware of the wifi antenna , before installing the webcam .

Microphone , as in most of the laptop , the microphone is present just near the screen bezel , and hence , need to be aware of before the installation process of the webcam .

Answer:

The correct option is WIFI antenna.

Answer:

Transport layer:

- data packets are segment to smaller chunks.

- gives sequence number to segment.

- identifies the source and destination port number.

- initiates data transmission between nodes.

- rearrange and identifies the application, the transmitted data is meant for.

Explanation:

The transport layer is the fourth layer in the OSI network model. Protocols like TCP and UDP are found in this layer. It segment data packets and for a connection oriented protocol like TCP, it creates an established session between source and destination host (the session layer can also do this, but it is more defined in the transport layer).

The network and data-link layer can also transmit data packets.

Answer:

tell him to do it himself and call him lazy

(i know im a genius)

To ensure a loop executes as long as the user inputs a non-negative number, you can utilize a while loop in your code. The loop should continue if the condition is true, where the input number is greater than or equal to zero. Here's a sample code snippet:

number = int(input('Enter a number: '))

while number >= 0:

   print('Body')

   number = int(input('Enter a number: '))

print('Done')

This loop begins by prompting the user to enter a number. The while condition checks if the entered number is non-negative (i.e., greater than or equal to zero). If the condition is met, the loop 'Body' is executed, followed by another prompt for the user to input a number. This process repeats until the user inputs a negative number, which causes the while loop to end, and the program prints 'Done' after exiting the loop. Using a break statement isn't necessary here because the loop condition naturally terminates when a negative number is entered.

Answer:

Rescue disk

Explanation:

The computer system is an electronic device with a circuitry of interconnected hardware devices like processors, input devices, output devices and storage devices. It's hardware is controlled by a kernel software provided by a system software called the operating system.

The operating system is stored in the storage device (HDD or SSD) and is loaded to run on the system during the boot process.

A common practice is to create a restore point in a partition of the primary storage or in an external storage disk, when a software from an untrusted vendor is to be installed. This partition or storage is called a rescue disk.

A rescue disk is used to recover the normal operation of the computer system software by re-installing the operating system restore point.

Answer:

Spyware

Explanation:

Internet is a type of computer network that allow device communicate with each other world wide. So, it is not the correct option.

Worm: this is a standalone malware computer program that replicates itself in order to spread to other computers. It spreads copies of itself from computer to computer. A worm can replicate itself without any human interaction, and it does not need to attach itself to a software program in order to cause damage. The major feature of a worm is ability to replicate on it own. So, it is not the correct option.

Bot: this is a software application that runs automated tasks. So, it is not the correct option.

Middleware: this is software that lies between an operating system and the applications running on it, enabling communication and data management. It provides services to software applications beyond those available from the operating system. So, it is not the correct option.

Spyware: this is the correct answer. Spyware is similar to trojan horse because it hides itself in a system and a user may not know that it exist on the system. Spyware is a form of malware that hides on your device, monitors your activity, and steals sensitive information without knowledge of the user.

Answer:

Spyware

Explanation:

Computer network systems are intercommunication of connected devices, to share resources within and to other remote networks. Network security policies and technical control system technologies are used by a network or system administrator to prevent unauthorized and unauthenticated access to user account in the network by cyber attackers.

Cyber attackers are individuals or group of individuals with the traditional hacking skills to exploit network and system vulnerabilities, to steal information. Malwares are used by hackers to covertly access networks. The spyware is a monitoring Trojan horse malware, used to monitor the activities of a user, steal information for fraudulent purposes.

Explanation:

import java.lang.Math;

import java.util.Scanner;

public class Triangle extends GeometricObject {

 double side1, side2, side3;

 protected Triangle() {}

 protected Triangle(double s1, double s2, double s3) {

Final answer:

A Triangle class in Java entails creating a subclass of GeometricObject with fields for its sides, methods to calculate its area and perimeter, and an overridden toString method. Test the class with a program that gathers user inputs to instantiate a triangle and display its attributes.

Explanation:

The student's question pertains to the construction of a Triangle class in Java that extends a given GeometricObject abstract class. To design this class, one must include three data fields representing the sides of the triangle, constructors for default and specified values, accessor methods for the sides, a method to calculate the area of the triangle, a method to calculate the perimeter, and an override of the toString method to describe the triangle.

The test program will prompt the user for inputs regarding the sides, color, and fill of the triangle and will use this information to create a Triangle object and display its attributes.

Example Implementation:

public class Triangle extends GeometricObject {
   private double side1 = 1.0, side2 = 1.0, side3 = 1.0;
   public Triangle() {}
   public Triangle(double side1, double side2, double side3) {
       this.side1 = side1;
       this.side2 = side2;
       this.side3 = side3;
   }
   // Accessor methods
   public double getSide1() {
       return side1;
   }
   public double getSide2() {
       return side2;
   }
   public double getSide3() {
       return side3;
   }
   // Area calculation using Heron's formula
   public double getArea() {
       double s = (side1 + side2 + side3) / 2;
       return Math.sqrt(s * (s - side1) * (s - side2) * (s - side3));
   }
   // Perimeter calculation
   public double getPerimeter() {
       return side1 + side2 + side3;
   }
   // Description of Triangle
   Override
   public String toString() {
       return "Triangle: side1 = " + side1 + " side2 = " + side2 + " side3 = " + side3;
   }
}

To test the Triangle class, one can implement a Driver program within the same file that uses a Scanner to collect user input, initializes a Triangle object, sets its attributes, and finally prints the area, perimeter, color, and filled status.

   public static void main(String[] args) {

      String []wordArray = {"John", "James", "David", "Peter", "Davidson"};

       System.out.println(Arrays.toString(listLengthOfAllWords(wordArray)));

       }

   public static int[] listLengthOfAllWords(String [] wordArray){

       int[] intArray = new int[wordArray.length];

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

           int lenOfWord = wordArray[i].length();

           intArray[i]=lenOfWord;

       }

       return intArray;

   }

}

This program gives the following array as output: [4, 5, 5, 5, 8]

Solution:

Some of the PHP functions used to interpret common HTML and URL encodings are as follows:

urlencode:

This function is used for encoding a string to be used in a query part of a URL and this is used as a convenient way to pass variables to the next page of a web form.

urldecode(): Same as urlencode() but in a reverse way. It is used to decode URL-encoded string

htmlentities(): This PHP function is used to convert all applicable characters to HTML entities

html_entity_decode(): This function converts HTML entities to characters and it is the reverse form of htmlentities() function.

Answer:

Hi there! The question is asking for a simple loop implementation that prints payment advice for Payroll.

Explanation:

Assuming that the payment method is “mailed check” for hours worked less than 30 and “direct deposit” for hours worked greater than 30, we can implement the function as below.  

hours_worked = [45, 15, 63, 23, 39]

payment_method = “mailed check”

for (int index = 0; index < 5; index++) {

   if hours_worked[index] > 30 {

      payment_method = “direct deposit”

   }

   print(“Paying “ + (hours_worked[index] * pay_rate) + “by “ + payment_method)

}

To calculate the payments for a list of employees with given worked hours, a for loop can be used to multiply each hour count by the fixed rate of pay and print alternating payment method statements.

Using a definite loop, such as a for loop in a programming language, we can easily calculate the individual paychecks for a list of employees and their respective hours worked. Assuming a fixed rate of pay of $10 per hour, we can loop through a list with the values 45, 15, 63, 23, and 39 to calculate the gross pay for each employee. Since our task is to print a statement for the method of payment, alternating between direct deposit and mailed check, we would end up with statements that reflect the total pay multiplied by the rate_of_pay. Below is a potential implementation of such a loop:

This example takes the given hours, multiplies them by the rate of pay, and prints out a statement that indicates the payment amount and method.

Answer:

Option 1 is the correct answer for the above question

Explanation:

In the provided code of 'SomeClass', the variable 'VALUE1' is a class constant because it is the only one declared as public, static, and final, indicating a constant value that cannot be changed.

In Java, a class constant is typically defined with the keywords public, static, and final. A class constant is a variable with a constant value that cannot be changed. In the given class SomeClass, the variable VALUE1 is declared with these keywords: public static final. Therefore, VALUE1 is a class constant. It is important to understand that class constants are useful for defining values that should not change throughout the execution of a program. Since it is declared with the final keyword, it must be assigned a value only once, and it cannot be modified afterwards.

The code is implemented based on the given operations.

To design and implement the dayType class, define the instance variable 'day' to store the day of the week. Create methods to set the day, print the day, return the day, return the next day, return the previous day, and calculate the day by adding certain days. Test the class by creating an object and calling the methods.

To design and implement the dayType class, we can start by defining the instance variable 'day' to store the day of the week. We can then create a setDay method to set the value of 'day', and a printDay method to print the current day. The returnDay method can be used to return the current day, and the nextDay and previousDay methods can be implemented to calculate and return the next and previous days based on the current day. To calculate the day after adding a certain number of days, we can create a calculateDay method that adds the given number of days to the current day and returns the resulting day. Lastly, appropriate constructors can be added to initialize the object with a specific day.

Here is an example implementation of the dayType class in Python:

To test the class, you can create an object of the dayType class with a specific day, and call the different methods to perform the required operations.

Question continuation

Determine the following probabilities:

a. P(A)

b. P(B)

c. P(A ∩ B)

d. P(A ∪ B)

Answer:

a. P(A) = 0.1389

b. P(B) = 0.1389

c. P(AnB) = 0.0193

d. P(AuB) = 0.2585

Explanation:

Given

Password length = 6

Letters (a-z) = 26

Integers (0-9) = 10

Total usable characters = 26 + 10 = 36

a. P(A) = Probability that a password begins with vowel (a,e,i,o,u)

Probability = Number of required outcomes/ Number of possible outcomes

Number of required outcomes = Number of vowels = 5

Number of possible outcomes = Total usable characters = 36

P(A) = 5/36

P(A) = 0.13888888888

P(A) = 0.1389

b. P(B) = Probability that the password ends with an even number (0,2,4,6,8)

Probability = Number of required outcomes/ Number of possible outcomes

Number of required outcomes = Number of even numbers = 5

Number of possible outcomes = Total usable characters = 36

P(B) = 5/36

P(B) = 0.13888888888

P(B) = 0.1389

c. P(AnB)

This means that the probability that a password starts with a vowel and ends with an even number

P(AnB) = P(A) and P(B)

P(AnB) = P(A) * P(B)

P(AnB) = 5/36 * 5/36

P(AnB) = 25/1296

P(AnB) = 0.01929012345

P(AnB) = 0.0193 ----_---- Approximately

d. P(AuB)

This means that the probability that a password either starts with a vowel or ends with an even number

P(AuB) = P(A) or P(B)

P(AuB) = P(A) + P(B) - P(AnB)

P(AuB) = 5/36 + 5/36 - 25/1296

P(AuB) = 335/1296

P(AuB) = 0.25848765432

P(AuB) = 0.2585 ----_---- Approximately

Final answer:

Calculating the probability of events A and B for passwords satisfying specific conditions.

Explanation:

A denote the event that a password begins with a vowel and B denote the event that a password ends with an even number. The total number of possible passwords is 36^6 (26 letters + 10 integers). To determine the probability of A, we calculate the number of passwords that start with a vowel (5 vowels) followed by any character (36 options) for the remaining 5 characters. Similarly, to find the probability of B, we consider passwords that end with an even number (5 options) and any character for the other 5 places.

Probability of A = (5 * 36^5) / 36^6
Probability of B = (5 * 36^5) / 36^6
