A software firm is going to develop an application for the automation of various office activities within an organization. In the office where application needs to deployed, different tasks are carried out on daily basis which are distributed among a hierarchy of employees working at the different levels. It is decided to use system architecture approach which deploys different server machines to handle application logic, data and files of the system and employees will access the system through a GUI installed on their machines. Question: In order to make the system more maintainable, which architecture partitioning approach from the following would you suggest for implementing this application design? · Vertical partitioning · Horizontal partitioning
Answer:
Horizontal partitioning
Explanation:
As the planned software will be used inside an office, the ideal is that the system uses horizontal partitioning. This is because a clerk performs a large number of activities with a high degree of variability. To support this type of service, horizontal partitioning is recommended because it allows the partition of tables in many lines, in addition to promoting the connection between different tables. Vertical partitioning cannot do this type of activity, which would end up limiting software that would not work satisfactorily.

Which is an example of correct HTML?
<h1>This is a heading </h1>
</h1>This is a heading<h2>
</h1>This is a title</h1>
<p/>This is a title</p>
please help! god bless you all
Answer: The first option
Explanation: In HTML, tags are used to classify the format of text between them. The correct usage of a tag is shown in the first option, with the first tag, <h1>, proclaiming that the following text is a part of the first header (hence h1), and the second tag proclaiming the conclusion of the first (the forward slash before the h1 in the second tag shows that the first tag is being concluded, and no text past that point pertains to the tags).

Answer:
Following are the answer to this question:
Explanation:
In this question firstly, it is important to recognize the basics behind its robust cloud-based system, which is the term durability, but also the servers can rapidly retrieve all the information and also that the durable cloud-based framework, which is like the user information has been present, if there is an abrupt failure to any bugs, and although the data are capable of becoming robust. It is the manual that describes it all, so the things reached in other urban centers as well. But when we have a robust cloud-based system in the business so we need to transfer data from the durable system too.
Write an expression to print each price in stock_prices. Sample output with inputs: 34.62 76.30 85.05
Answer:
Here is the Python program:
stock_prices = input().split() #to take input and splits it into a list
for price in stock_prices: #iterates through stock_prices
print("$",price) #prints each value of stock_prices with a dollar sign
Explanation:
The program is well explained in the attached comments. I will explain the logic of the program with the help of an example:
Suppose the user enters the following input as stock_prices values
34.62 76.30 85.05
input() method is used to take input from user
split() method is used to split or break this input string and returns a list of strings as:
['34.62', '76.30', '85.05']
Now the statement for price in stock_prices: iterates through each item of the list and print("$",price) prints each value of list with a dollar sign on the output screen as:
$ 34.62
$ 76.30
$ 85.05
The program inputs the dollar sign to each of the user inputted stick prices. The program written in python 3 goes thus ;
t = input('Enter values : ')
#takes inputs from user for stock prices
stock_prices = [eval(x) for x in t.split()]
#splits the values based on whitespace assigns to a list variable using list comprehension
for price in stock_prices :
#iterates through the prices in the list
print("$", price)
#place the dollar sign behind each value and display

(Game: scissor, rock, paper) Write a program that plays the popular scissor-rockpaper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses, or draws. Here are sample runs: scissor (0), rock (1), paper (2): 1
The computer is scissor. You are rock. You won scissor (0), rock (1), paper (2): 2
The computer is paper. You are paper too. It is a draw
Answer:
Here is the JAVA program:
import java.util.Scanner; //used to take input from user
public class RockPaperScissor{
public static void main(String[] args) { //start of main function
Scanner input = new Scanner(System.in); // creates Scanner class object
String[] choice = {"Scissor","Rock","Paper"}; // stores choices
System.out.print("scissor (0), rock (1), paper (2), quit (3): "); //prompts user to enter a choice 0 for scissor 1 for rock and 2 for paper and 3 to exit
int userChoice = input.nextInt(); //reads user's choice
while (userChoice != 3) {// loop iterates until user enters 3 to quit
if ( userChoice>=0 && userChoice<3) { //checks if use enters choice from 0 to 2 (for each option)
int compChoice = (int)(Math.random() * 2); //generate random number between 0 to 2
System.out.print("The computer is " + choice[compChoice]); //prints computer choice from rock paper scissor
System.out.print(" You are " + choice[userChoice]); //prints user choice from rock paper scissor
winner(compChoice,userChoice); } //calls winner method to declare winner
System.out.print("scissor (0), rock (1), paper (2) quit (3): "); //prompts user to enter a choice
userChoice = input.nextInt(); } } //reads choice from user
public static void winner(int computer, int player){//method to declare winner
boolean win = false; // boolean type variable initialized to false
if (computer == player) // if choice of computer is same as that of user
System.out.println(" It is a draw"); //prints this message if there is a tie
else {
win = (player == 0 && computer == 2) || (player == 1 && computer == 0) ||
(player == 2 && computer == 1); //checks user choice with computer choice
if (win) // if win holds
System.out.println(" You won"); //user wins
else
System.out.println(" You lost"); }}}//user loses
Explanation:
The program prompts user to enter a choice. The choice is 0 for scissor, 1 for rock, 2 for paper and 3 to quit.
The while loop continues to execute until the user enters 3 to quit the program. Inside the while loop, the if condition checks if the user enters a valid choice that is from 0 to 2. For computer choice, the program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper using Math.random() method from the range 0 to 2.
Then the function winner() is called to declare the winner of the game. The winner method takes two arguments i.e computer choice and player choice. Lets say user enters 0 (scissors). The variable win has the following options in order to declare the winner. If anyone of these evaluate to true then the user wins otherwise the user loses.
win = (player == 0 && computer == 2) || (player == 1 && computer == 0) ||
(player == 2 && computer == 1);
In the above statement the first part is (player == 0 && computer == 2) means if player choice is 0 (scissor) and computer's choice is 2 (randomly generated) which represents paper then this means scissors cuts paper so user wins.
The second part (player == 1 && computer == 0) means if player choice is 1 (rock) and computer's choice is 0 (randomly generated) which represents scissor then this means rock crushes scissors so user wins.
The third part of the above statement (player == 2 && computer == 1) means if player choice is 2 (paper) and computer's choice is 1 (randomly generated) which represents rock then this means paper covers rock so user wins.
if (wins) means if any of the above mentioned conditions in win holds true then the user wins else user loses.

Which of the following statements are true regarding the fetch-execute cycle? Select 3 options.
A. The device responsible for performing the fetch-execute cycle is the CPU.
B. Fetch refers to saving output to the hard drive.
C. Each step of the fetch-execute cycle is performed for each instruction.
D. The order of steps in the fetch-execute cycle is fetch-decode-execute-store.
E. The fetch-execute cycle is only carried out when a user types in input.
Answer:
A, C, & D
Explanation:
The fetch execution cycle refers to the execution of instructions by the CPU. This is a multi-step process in which instructions are fetched, decoded, executed, and then stored. The result of this cycle allows an instruction to be executed by the CPU allowing the process cycle to continue.
The statements which are true regarding the fetch-execute cycle are;
A. The device responsible for performing the fetch-execute cycle is the CPU.
C. Each step of the fetch-execute cycle is performed for each instruction.
D. The order of steps in the fetch-execute cycle is fetch-decode-execute-store.
A fetch-execute cycle is also referred to as instruction cycle and it can be defined as the order of sequential steps or basic operation cycle that the central processing unit (CPU) of a computer performs to execute an instruction.
Basically, the fetch-execute cycle refers to a computer's basic operation cycle. Thus, it involves a process through which data (information) is received by the central processing unit (CPU) of a computer and determines what to do with the data (information).
Furthermore, the fetch-execute cycle comprises four (4) main phases and these includes;
Fetch: this is the stage where an instruction is collected by the central processing unit (CPU) of a computer and prepared for decoding.Decode: it determines what to do with the instruction after understanding the set of commands (instruction set) received.Execute: the decoded instructions are then executed by the Arithmetic Logic Unit (ALU) of the central processing unit (CPU).Store: the output or results are then sent and written in the main memory of the computer.In conclusion, we can deduce the following points from the above explanation;
1. The device responsible for performing the fetch-execute cycle is the central processing unit (CPU).
2. Each step of the fetch-execute cycle is performed for each instruction.
3. The order of steps in the fetch-execute cycle is fetch-decode-execute-store.
