Key tone is a presentation software. it is used to make presentation and add animation and transition to it.
Database
Database is incorrect because databases are used for storing data. Not for presentation.
Create a Java program that takes input of a list of integers from the user, stores them into an array and then finally uses the array contents to output the list of integers in reverse. The user's input begins with the number of integers to be stored in the array. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers.
Answer:
This question is answered using Java
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Length of array: ");
int len = input.nextInt();
int[] intArray = new int[len];
for(int i = 0; i<len;i++){
intArray[i] = input.nextInt();
}
for(int i = len-1; i>=0;i--){
System.out.print(intArray[i]+" ");
}
}
}
Explanation:
This line prompts user for length of array
System.out.print("Length of array: ");
This gets the length of the arrau
int len = input.nextInt();
This declares the array as integer
int[] intArray = new int[len];
The following iteration gets input to the array
for(int i = 0; i<len;i++){
intArray[i] = input.nextInt();
}
The following iteration prints the array in reversed order
for(int i = len-1; i>=0;i--){
System.out.print(intArray[i]+" ");
}
In a text messaging system, data is sent from one device to another. Devices are recognized by a unique device ID. The format of the message is sent as a string with information about the number of characters in the device ID, the device ID itself, the number of characters in the text message and the text message that is being sent with each part being separated by a space. The system uses this information to send the message to the correct device and the receiving device displays only the text message. The number of words in the text message is also useful. A word is defined by strings separated by spaces.
Here is a sample VALID message:
04 1234 05 hello
The first two digits in the string represent the length of the device ID to follow.
The device ID is the number of characters following the length. Note that the device ID may not be limited to number values.
Following the device ID is the length of the text message and then the text message itself. The text message may be any combination of characters (such as letters, numbers or symbols) and may include spaces.
This message contains one word.
Here is a sample INVALID message:
06 a2b10 09 I’m ready
The first two values 06 indicate the device ID length. The device ID is a2b10 which has a length of 5. This does not match the specified length 06. Thus, this is NOT a valid message.
This message contains two words.
The Message class represents messages in this system. A Message must have a device ID, the length of the ID, the length of the message and the text message being sent in order to be a valid message sent through the system. The Message class must determine if a message is valid in order to send a message. A valid message is one where the device ID length matches the given length in the message string and the text message length matches the length of the supplied text message. The text message consists of one or more words where the length of the text message string is at least one character.
Consider the code below:
Message msg1 = new Message("08 abc123xy 16 Computer Science"); //creates a new message object
boolean msg1Valid = msg1.isValid(); // returns true for a valid message
String text = "11 radio11a287 14";
Message msg2 = new Message(text);
boolean msg2Valid = msg2.isValid(); // returns false for an invalid message
Message msg3 = new Message("04 92a1 16 Computer Science");
Message msg4 = new Message("03 x8r 21 Today is a great day!");
int numWords = msg4.wordCount(); //returns 5, the number of words in the
//text message
Complete the Message class by writing the isValid() and wordcount() methods.
public class Message{
private int idLength;
private String deviceID;
private int msgLength;
private String textMsg;
public Message(String msg){
//implementation not shown
}
public boolean isValid(){
//to be written
}
public int wordCount(){
//to be written
}
Answer:
public int wordCount() {
String[] arr = textMsg.split(" ", 0);
return arr.length();
}
public boolean isValid() {
if (idLength == deviceID.length()) {
if (msgLength == textMsg.length()) {
return true;
} else {
return false;
}
return false;
}
Explanation:
The Java source code defines two methods in a class named Message namely; isValid() and wordCount(). The isValid() method evaluates the validity of a message sent to return a boolean value while the wordCount() counts and returns the number of words in the message.

A device is sending out data at the rate of 1000 bps. How long does it take to send
out (a)10 bits, (b) a single character (8 bits) and (c)100,000 characters?
Answer:
0.01 second ; 0.008 seconds; 800 seconds
Explanation:
Given that:
Sending rate = 1000 bps
Rate of 1000 bps means that data is sent at a rate of 1000 bits per second
Hence, to send out 10 bits
1000 bits = 1 second
10 bits = x
1000x = 10
x = 10 / 1000
x = 0.01 second
2.)
A single character 8 - bits
1000 bits = 1 second
8 bits = (8 / 1000) seconds
= 0.008 seconds
3.)
100,000 characters = (8 * 100,000) = 800,000
1000 bits = 1 second
800,000 bits = (800,000 / 1000)
= 800 seconds

The attenuation of a signal is -10 dB. What is the final signal power if it was originally
5 W?
Answer:
P₂ = 0.5 W
Explanation:
It is given that,
The attenuation of a signal is -10 dB.
We need to find the final signal power if it was originally 5 W.
Using attenuation for signal :
[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]
Put dB = -10, P₁ = 5 W
Put all the values,
[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]
So, the final signal power is 0.5 W.
The final signal power if it was originally 5W is; 0.5 W
Signal PowerWe are given;
Attenuation signal; dB = -10 dBOriginal signal power; P1 = 5 WFormula for attenuation signal is;
dB = 10log_10_ (P2/P1)
Where P2 is final signal power
Thus;
-10 = 10log_10_(P2/5)
-10/-10 = log_10_(P2/5)
-1 = log_10_(P2/5)
0.1 = P2/5
P2 = 0.1 × 5
P2 = 0.5 W

B) programmers don't need to worry about race conditions.
C) a thread cannot block inside a critical section.
D) deadlock cannot occur.
Answer:
A. Management of entry and exit code is managed by OpenMP library reducing the possibility of programming errors
Explanation:
This is a multiple choice question and this is the answer because:
1. OpenMp is inclusive of an APL/compiler directives:
2. any code which follows #pragma omp parallel is a parallel region and it is performed by large number of threads that are same as the number of processing cores that are in the system.
3. The critical-section compiler directive acts more like a binary semaphore or mutex lock,it makes sure that only one thread is active in the critical section at the same time.

Part 1:
Use MySQL Workbench to create an EER model for a database that stores information about the downloads that users make. (When you create the EER model, it will be given a default name of mydb. For this exercise, it’s not necessary to change this name.) Define the tables that are necessary to implement this data structure:
Each user must have an email address, first name, and last name.
Each user can have one or more downloads.
Each download must have a filename and download date/time.
Each product can be related to one or more downloads.
Each product must have a name.
When you’re done defining the tables, create a diagram for the database. Then, use the diagram to define the required relationships. When you do that, be sure to use the relationship button that uses existing columns.
Part 2:
Create a view named order_item_products that returns columns from the Orders, Order_Items, and Products tables.
This view should return these columns from the Orders table: order_id, order_date, tax_amount, and ship_date.
This view should return the product_name column from the Products table.
This view should return these columns from the Order_Items table: item_price, discount_amount, final_price (the discount amount subtracted from the item price), quantity, and item_total (the calculated total for the item).
Part 3:
Write a SELECT statement that uses the view that you created in part 2 to get total sales for the five best selling products. Sort the result set by the order_total column in descending sequence.

How many times will line 7 be executed when the following code is run?
String str = "rebellion";
int i = 0;
int j = str.length() - 1;
String result = "";
while (i < j)
{
result = str.substring(i, i + 1) + result + str.substring(j, j + 1);
i++;
j--;
}
System.out.println(result);
(Java)
Answer:
4 times
Explanation:
Required.
How many times will line 7 be executed?
Line 2 initialises i to 0
Line 3 subtracts 1 from the length of "rebellion" , the result of the subtraction is then saved in J
So:
j = 9 - 1
j = 8
From line 2 and line 3, we have that:
i = 0 and j = 8
Line 4 is an iteration that is repeated as long as i is less than j
Line 7 will be executed, for the first time as: i < j because 0 < 8
i is incremented to 1 and j is reduced to 7
Line 7 is then executed again, the second time because 1 < 7
i is incremented to 2 and j is reduced to 6
Line 7 is then executed again the third time because 2 < 6
i is incremented to 3 and j is reduced to 5
Line 7 is then executed again the fourth time because 3 < 5
i is incremented to 4 and j is reduced to 4
At this stage, line 7 will no longer be executed because I is no longer less than as 4 = 4.
Hence, number of execution is 4 times
