Which of the following statements are true about the ability for devices A and C to communicate?
Answers
The network is fault tolerant. If a single connection fails, any two devices can still communicate. Computers B and F need to first communicate with at least one other device in order to communicate with each other. The correct statements are I and II.
What is a network?Computer networking is the term for a network of connected computers that may communicate and share resources.
These networked devices transmit data through wireless or physical technologies using a set of guidelines known as communications protocols.
Local-area networks (LANs) and wide-area networks are two fundamental types of networks (WANs). LANs use links (wires, Ethernet cables, fibre optics, and Wi-Fi) that carry data quickly to link computers and peripheral devices in a constrained physical space, such as a corporate office, lab, or college campus.
The network can withstand errors. Any two connected devices can still communicate even if one connection breaks. In order to communicate with at least one other device, Computers B and F must first communicate with that device.

Initial temperature (T1) = 20°C
Heat (Q) added = 35 KJ
Specific heat capacity (C) = 4.18 KJ/Kg°C
Final temperature (T2)
The final temperature of water can be obtained as follow:
Q = MC(T2 – T1)
35 = 0.3 x 4.18 (T2 – 20)
35 = 1.254 (T2 – 20)
Clear the bracket
35 = 1.254T2 – 25.08
Collect like terms
1254T2 = 35 + 25.08
1.254T2 = 60.08
Divide both side by the coefficient of T2 i.e 1.254
T2 = 60.08/1.254
T2 = 47.9 ≈ 48°C

What is Huffman code?
A lossless data compression algorithm is huffman coding. Input characters are given variable-length codes, the lengths of which are determined by the frequency of the matching characters.
The character used the most often is given the smallest code, and the character used the least often is given the largest code.
The variable-length codes (bit sequences) assigned to input characters are Prefix Codes, which indicates that no other character will have a code that is the prefix of the code assigned to that character.
This is how Huffman Coding ensures that the produced bitstream cannot contain any ambiguities during decoding.
The concept of prefix code, which states that a code associated with a character should not be included in the prefix of any other code, is used by Huffman Coding to avoid any ambiguity in the decoding process.

Write a program that reads integers, finds the largest of them, and counts its occurrences. Assume the input ends with number 0. Suppose you entered 3 5 2 5 5 5 0; the program finds that the largest is 5 and the occurrence count for 5 is 4. (Hint: Maintain two variables, ln ax and count. The variable max stores the current maximum number, and count stores its occurrences. Initially, assign the first number to max and 1 to count. Compare each subsequent number with max. If the number is greater than max assign it to max and reset count to 1 If the number is equal to max increment count by 1.)
Answers
The program requires the user to enter the number until the user enters 0. As the user enters zero, the program will display the largest number among other numbers that the user has entered and also display its occurrence. The required program is written in Java programming language below.
import java.util.Scanner;//import scanner class for taking input
public class MaxNumberFinder {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
// ask or prompt user to enter the number
System.out.print("Enter numbers: ");
int maximum = input.nextInt();// assign entered number to max
int counter = 1; // assign 1 to count
int userNumber=1; // hold for future
// Assume that the input ends as user enter zero
while (userNumber > 0) {
userNumber = input.nextInt();
if (userNumber > maximum) {
maximum = userNumber;
counter = 1;
}
if (userNumber == maximum)
counter++;
}
// Print result on the screen
System.out.println("The largest number is " + maximum);
System.out.println(
"The occurrence of the largest number is " + counter);
}
}

an analyst is cleaning a new dataset containing 500 rows. they want to make sure the data contained from cell b2 through cell b300 does not contain a number greater than 50. which of the following countif function syntaxes could be used to answer this question? select all that apply.
Answers
The countif function syntaxes that could be used to answer this question is =COUNTIF(B2:B300,"<=50").
The COUNTIF function counts the number of cells in the specified range that meet the criteria specified in the second argument (the criteria). In this case, the criteria is a string that specifies the condition "less than or equal to 50", so the function will count the number of cells in the range B2:B300 that contain a value less than or equal to 50. Here is an example of how you could use the COUNTIF function in a formula to check if the values in the range B2:B300 are less than or equal to 50:
=COUNTIF(B2:B300,"<=50")

Write a description of the Polynom3 class of polynomials of the 3rd degree from one given variable
an array of coefficients.
Provide overloading methods for copy operator=(), assembly operations
operator+(), operator-() subtraction and operator*() multiplication of polynomials with the result
of a new object - a polynomial, printing (output to a stream).
Answers
Answer:The Polynom3 class represents polynomials of the third degree from one given variable with an array of coefficients. It has the following methods:
Polynom3(const Polynom3& other): This is the copy constructor, which creates a new Polynom3 object as a copy of another Polynom3 object.
Polynom3& operator=(const Polynom3& other): This is the copy assignment operator, which allows you to assign one Polynom3 object to another, replacing the original object with a copy of the other object.
Polynom3 operator+(const Polynom3& other) const: This is the addition operator, which adds two Polynom3 objects and returns a new Polynom3 object representing the sum of the two polynomials.
Polynom3 operator-(const Polynom3& other) const: This is the subtraction operator, which subtracts one Polynom3 object from another and returns a new Polynom3 object representing the difference between the two polynomials.
Polynom3 operator*(const Polynom3& other) const: This is the multiplication operator, which multiplies two Polynom3 objects and returns a new Polynom3 object representing the product of the two polynomials.
friend std::ostream& operator<<(std::ostream& out, const Polynom3& polynom): This is the output operator, which allows you to print a Polynom3 object to an output stream, such as std::cout.
Here is an example of how you could use these methods:
Polynom3 p1({1, 2, 3}); // Creates a polynomial p1 = 1x^2 + 2x + 3
Polynom3 p2({4, 5, 6}); // Creates a polynomial p2 = 4x^2 + 5x + 6
Polynom3 p3 = p1 + p2; // Creates a new polynomial p3 = 5x^2 + 7x + 9
Polynom3 p4 = p1 - p2; // Creates a new polynomial p4 = -3x^2 - 3x - 3
Polynom3 p5 = p1 * p2; // Creates a new polynomial p5 = 4x^4 + 13x^3 + 22x^2 + 17x + 18
std::cout << p3 << std::endl; // Outputs "5x^2 + 7x + 9" to the console
Explanation:
The third-degree polynomials from a given variable with an array of coefficients are represented by the Polynom3 class.
What is a C++ program?Many people believe that C++, an object-oriented programming (OOP) language, is the finest language for developing complex applications.
The copy assignment operator, Polynom3& operator=(const Polynom3& other), enables you to assign one Polynom3 object to another, replacing the original object with a duplicate of the other object.
The addition operator, Polynom3 operator+(const Polynom3& other), returns a new Polynom3 object that represents the sum of the two polynomials after adding two Polynom3 objects.
This Polynom3 operator subtracts one Polynom3 object from another using the formula (const Polynom3& other).
The Polynom3 operator*(const Polynom3& other) const multiplies two Polynom3 objects and creates a new Polynom3 object that represents the result of the multiplication.
Thus, this way, a description of the Polynom3 class of polynomials of the 3rd degree from one given variable can be done.
