7. Which of these statements is true? Agile is a programming language MySQL is a database HTML stands for "Hypertext Markup Link

Response:

refer to the explanation

Clarification:

Examine the SQL statement shown below:

SELECT c.CustomerName, e.LastName, s.ShipperName, p.ProductName, o.Quantity, od.OrderDate

FROM

Customers c, Employees e, Shippers s, Orders o, OrderDetails od, Products p

WHERE c.customerID = o.customerID AND

e.employeeID = o.employeeID AND

o.orderID = od.orderID AND

od.shipperID = s.shipperID AND

od.productID = p.productID;

The banking system that poses greater risk of vulnerabilities is the one with ten branches dispersed across California, where data resides on a central mainframe located in San Francisco. If the branches do not share data across the network, the risk of hacking is reduced. However, with a network setup, both data sharing and centralized storage increase exposure to unauthorized access.

Answer:

Below is the JAVA program:

import java.util.Scanner;   //to take input from user

public class Main {  //name of the class

  public static void main(String[] args) {  //beginning of main method

      Scanner input = new Scanner(System.in);  //creates Scanner instance

      int integer = input.nextInt();  //defines and collects an integer for the number of words

      String stringArray[] = new String[integer]; //initializes an array to hold strings

      for (int i = 0; i < integer; i++) {  //iterates through the array

          stringArray[i] = input.next();         }  //collects strings

      int frequency[] = new int[integer];  //creates an array for holding frequencies

      int count;         //initializes variable to calculate frequency of each word

      for (int i = 0; i < frequency.length; i++) {  //iterates through frequency array

          count = 0;  //sets count to zero

          for (int j = 0; j < frequency.length; j++) {  //iterates through array

              if (stringArray[i].equals(stringArray[j])) {  //checks if element at ith index matches jth index

                  count++;                 }            }  //increments count

          frequency[i] = count;      }  //stores count in the frequency array

      for (int i = 0; i < stringArray.length; i++) {  //iterates through the string array

          System.out.println(stringArray[i] + " " + frequency[i]);         }    }    } //displays each word and its frequency

Explanation:

To illustrate the program, consider:

let integer = 3

for (int i = 0; i < integer; i++) is used to input strings into stringArray.

On the first pass:

i = 0

0<3

stringArray[i] = input.next(); takes a word and saves it to the ith index of stringArray. For example, if the user types "hey", it will be in stringArray[0].

Then, i increments to i = 1

On the second pass:

i = 1

1<3

stringArray[i] = input.next(); takes another word and assigns it to stringArray[1]. If the user enters "hi", then hi will be in stringArray[1]

Next, i becomes i = 2

On the third pass:

i = 2

2<3

stringArray[i] = input.next(); captures a word and places it in stringArray[2]. If the user types "hi", it goes to stringArray[2]

Then, i increments to i = 3

The loop terminates since i<integers is false.

The next outer loop for (int i = 0; i < frequency.length; i++) and inner loop for (int j = 0; j < frequency.length; will check each word and if (stringArray[i].equals(stringArray[j])) identifies any duplicates. Words that repeat will have their count incremented and the frequency array will record these values. For example, hey appears once while hi shows up twice, thus resulting in the final outputs:

hey 1

hi 2

hi 2

The visual representation of the program and its outcome based on the example provided is attached.

The primary issue was declaring int prod within the while loop, which caused prod to reset to 1 each time the loop executed.

Answer:

EMI and RFI

Explanation:

EMI, or Electromagnetic Interference, can also be referred to as Radio-frequency Interference (RFI) within the radio frequency domain.

An unshielded ethernet cable, made from copper, might function as an antenna; any external noise that interferes with it can corrupt the data signal, resulting in data integrity issues and distorted signals.
