In the Create Performance Task, you will be asked to identify an abstraction in your program and explain how it helps manage the complexity of the program. Functions are a form of abstraction. Pick a function you wrote in your solution to the 3x3 square problem and explain how it helps manage the complexity of your program.
Answer:
The selecting function to this question is:
turnRight();
longLine();
Explanation:
In the given question we select two function that are "turnRight() and longLine() ". turnRight() function would originally have 3 lefts and longLine() would be originally 3 forward, used a lot in the 3x3 grid. These function helps to control the complexity of the program because These functions have a graphical layout which has many phases to be replicated over and over. Functions reduced ambiguity and increased performance.Abstraction, such as functions, helps manage the complexity of a program by hiding details of certain parts of code and making the program's overall structure easier to understand. An example is using a function to calculate the area of mini-squares in a 3x3 square problem.
Explanation:In the context of the Create Performance Task, an abstraction is a way of managing the complexity of a program. It allows you to hide the implementation details of a part of your code, thus reducing complexity. A function is a common form of abstraction. For instance, in solving a 3x3 square problem, a function might be used to calculate the area of each mini-square. This function does a specific job and you don't have to worry about the details of how it calculates the area each time you use it.
This use of a function, an abstraction, allows the main part of your program to remain cleaner, more straightforward and less complex, making it easier to grasp the overall structure of the program. Abstraction, thus, helps in simplifying a program and managing its complexity.

Your company has a wireless network for its small office network. The wireless network does not broadcast its service set identifier (SSID). You configure a user's Windows Vista computer to connect to the wireless network by manually setting the SSID. You need to ensure that the user's computer does not send probe requests to discover if the wireless network is in range. What should you do?
Answer:
make sure that the "Connect even if the network is not broadcasting" is cleared
Explanation:
Based on the information provided within the question it can be said that in order to ensure this you should make sure that the "Connect even if the network is not broadcasting" is cleared. Otherwise this option will send probe requests in order to discover if a non-broadcasting network is in range. Therefore by clearing this option no probe requests will be sent.
Analyze the following code. Is count < 100 always true, always false, or sometimes true or sometimes false at Point A, Point B, and Point C?
int count = 0;
while (count < 100) {
// Point A
System.out.println("Welcome to Java!");
count++;
// Point B
}
// Point C
Answer:
Point A: Always True
Point B: Sometimes false
Point C: Always False
Explanation:
In the given code snippet. Point A is the first statement within the While loop the statement System.out.println("Welcome to Java!"); will only be executed if the while condition evaluates to true.
At Point B, The statement count++ increases the value of the counter at every iteration, while it will be true for most occasions, at the last increament, this statement will be false that is at count=100, The condition will be false at this point just before program execution breaks out of the loop
Point C is outside of the loop, this happens when the given condition is no longer true.
Final answer:
At Point A and B inside the while loop, 'count < 100' is sometimes true and sometimes false. However, at Point C, after the loop, it is always false because the loop halts when 'count' is no longer less than 100.
Explanation:
The code provided demonstrates a basic loop that uses a counter to control its execution. We'll analyze the condition count < 100 at three different points in the loop. Here's what happens at each point:
Point A: This is inside the while loop, just before the welcome message is printed. When the loop starts, count is initialized to 0, which is less than 100, so the condition count < 100 is true. As the loop continues executing, this condition is true until count reaches 99. Once count is incremented to 100, the loop ends, so at Point A, count < 100 is sometimes true and sometimes false, but it is always true whenever Point A is reached because if it weren't, the loop would not run.Point B: This point is just after the count variable is incremented. Here, count < 100 is sometimes true and sometimes false as well. When the count is incremented from 99 to 100, the condition will become false and the loop will stop executing afterward.Point C: This is after the loop has finished executing. At this point, the count < 100 condition is always false, because it's the condition for the loop to stop running. Hence, the loop only exits when count is not less than 100.To reduce costs and the environmental impact of commuting, your company decides to close a number of offices and to provide support for staff to work from home. However, the senior management who introduce the policy are unaware that software is developed using Scrum.
Explain how you could use technology to support Scrum in a distributed environment to make this possible.
What problems are you likely to encounter using this approach?
Answer:
Using services such as GitHub and Skype
Disorganization and Communication Problems
Explanation:
Scrum is a framework for projects that are almost exclusively about programming and coding. Which means that there is always group work involved and one of the most important elements of group work is efficient communication.
The company's decision of providing the employees the opportunity to work from their homes greatly interferes with this concept and most likely there will be issues.
Using Scrum in the development process while working from different locations forces the team to use different ways to communicate and collaborate effectively which i believe can be done by using services such as Skype and GitHub.
Using this approach does not eliminate all possibility of problems mentioned above. There can be miscommunication and desynchronization in terms of the coding process which can result in bugs in the code and delay of the final product.
I hope this answer helps.

Write a program that produces the following output (where the user may enter any positive integer under 10):______
Enter a positive integer under 10:_________
Answer:
// The Scanner class is imported to allow the program receive user input
import java.util.Scanner;
// The class is defined called Solution
public class Solution {
// The main method is defined which begin program execution
public static void main(String args[]) {
// Scanner object 'scan' which receive user input from the keyboard
Scanner scan = new Scanner(System.in);
// the userInput variable is initially set to 1 (true) to allow the program continue prompting the user for input
int userInput = 1;
// while loop which continue execution as long as the userInput is greater than 0 and less than 10
while (userInput > 0 && userInput < 10){
// Prompts is displayed to the user to enter number below 10
System.out.println("Enter a positive integer under 10:__________");
// the next input is assigned to userInput
userInput = scan.nextInt();
}
}
}
Explanation:
The above code continue prompting the user to input an integer as long as the input is greater than 0 and less than 10.
Final answer:
The provided program, written in Python, prompts the user to enter a positive integer under 10 and prints it out if it's within the valid range, otherwise it notifies the user of the incorrect input.
Explanation:
The question is asking for a simple program that prompts the user to enter a positive integer less than 10 and prints out a specific output. We can use a programming language like Python to achieve this. Below is an example of what the program might look like:
positive_integer = int(input("Enter a positive integer under 10: "))
if positive_integer > 0 and positive_integer < 10:
print("The number you entered is:", positive_integer)
else:
print("The number is not within the specified range.")
The program first asks the user to enter a positive integer. It then checks if the number is greater than 0 and less than 10 before printing it out. If the number is not within the valid range, it informs the user accordingly.
What is the system of phonographic disc recordings paired with a projector called?
A. cinematographe
B. kaleidoscope
C. kinetoscope
D. vitaphone
Final answer:
The D. Vitaphone is the correct answer, as it merged phonographic sound recordings with motion picture technology, playing a pivotal role in the development of talking films.
Explanation:
The system of phonographic disc recordings paired with a projector is called the Vitaphone. This technology became a significant milestone in the merge of visual and auditory entertainment, giving rise to the early forms of sound films. Although originally designed as a novelty, the phonograph became primarily an entertainment device.
Thomas Edison's interest in motion pictures led him to develop devices like the kinetograph and the kinetoscope, paving the way to the modern film industry. The Vitaphone was a later development that effectively synchronized sound with film, enhancing the storytelling capacity of motion pictures and contributing to the emergence of movie stars in the twentieth century. Hence, the correct answer to the student's question is D. Vitaphone.

Multinational companies can benefit from creating a global network of value creation activities. With this strategy various phases of the value chain are distributed in several global locations where the cost of value creation is greatly reduced and value maximized. In this scenario Lenovo strategically chooses locations for the manufacturing of components for their ThinkPad laptops, while factoring costs involved and ensuring they are at a minimum. As with any strategy, it has its limitations that can reduce effectiveness such as trade barriers and other political risks.
A crossover cable would normally be used in a 100BaseT network to connect __________.
Answer:
The answer is "directly computing device"
Explanation:
The Ethernet crossover cable used to connect computers directly. Two computers are used in the same form in this method and are mostly related.
The system is connected to two or more switches, and a mini LAN connected to one LAN or two separate hosts. It allows the connection to two hosts or a server to a customer without having a hub.Final answer:
A crossover cable is used in a 100BaseT network to directly connect two similar devices, such as computers, or networking equipment like switches and routers. This cable type crosses transmit and receive lines to enable direct communication, employing twisted pair wiring to minimize crosstalk and interference.
Explanation:
A crossover cable is typically used in a 100BaseT network to connect two similar devices directly to each other without the need for a switch or hub. This type of cable is useful for linking two computers together to form a small network or for connecting switches and routers without uplink ports. The wires within a crossover cable are crossed so that the transmitting signals on one end of the cable line up with the receiving signals on the other end, enabling two devices to communicate directly. Connections utilizing a crossover cable are critical in networks that operate at frequencies up to a few hundred kHz, and they also apply to systems such as Ethernet which can operate near 1 GHz. The use of twisted pair cables, like those in crossover cables, help to reduce crosstalk and other electromagnetic interference which would otherwise be problematic in both power and data transmission.

A(n) ______ includes the blank spaces, tabs, and line breaks found within the file.
Answer:
A White Space
Explanation:
A white space refers to any section of a file that has a space around an object. These spaces help to indicate blanks, separate individual words, line breaks and paragraphs of texts from other parts of the file (document). They are commonly used for formating text in files/documents in order to prevent overcrowded documents and help to improve readability.
A delimiter includes blank spaces, tabs, and line breaks in a file, critical for separating and properly aligning columns in flat files where data is structured in a tabular format.
Explanation:A delimiter or separator includes the blank spaces, tabs, and line breaks found within the file, especially in the context of flat files where structured data are organized. The role of the delimiter is to separate each column or field within the file. For instance, a space might separate the "name" column from the "height" column. However, to align the columns correctly, a tab is commonly used. These delimiters are vital for ensuring that the data in each column is correctly aligned and understood when the file is processed by different software programs.
Within a .txt file containing structured data, known as a flat file, whitespace characters play a significant role in formatting and organizing data. For example, in Linux, tabs are represented as \t and line breaks as \n. These whitespace characters, which include spaces, tabs, and newlines, form the basis of separating data into readable formats for processing.
A single central register of IP addresses and names (a DNS style system) is an efficient means of translating human readable names to IP addresses. Which of the following is NOT solved by DNS?
A. It is inefficient to have everyone on the Internet maintain their own list of IP addresses.
B. There are too few IP addresses to meet the current demand.
C. When someone new joins the Internet they must inform everyone else of the new IP address
D. When an IP address changes, it is impossible to locate a computer until the owner announces the change.
Answer:
Option B: There are too few IP addresses to meet the current demand.
is the correct answer
Explanation:
As the demand of changing human names to IP addresses, it is difficult to meet because the human names can be uncountable and unlimited while in comparison to the IP addresses are somehow limited.
As IP addresses should be unique so that they maybe identified so the this uniqueness factor will not be able to fulfilled when we try to change all the names to IP addresses.
I hope it will help you!Why do most laptops have LCD rather than OLED displays, which are found on mobile devices?
OLED displays are more expensive
OLED displays are too small
OLED displays have too high of a resolution
OLED displays have too low of a resolution
Laptops have LCDs rather than OLED displays because:
OLED displays are more expensive. OLED materials are made up of diodes which consists of different colors.
Laptops typically use LCD displays instead of OLED because OLED technology is more expensive to produce, despite its superior color and viewing angle capabilities.
The primary reason most laptops have LCD displays rather than OLED displays, which are commonly found in mobile devices, is cost-related. OLED technology, known for its ability to show truer blacks and its capacity for a wider viewing angle, is generally more expensive to produce than LCD.
LCD displays function through the use of liquid crystals that modulate light, but they do not emit it directly, which differs from OLED where each pixel emits its own light. Moreover, the resolution of OLED displays is not inherently too high or too low for laptop use; it is the production cost that is the limiting factor. It is important for consumers to weigh the benefits against the higher cost and determine whether the added value of an OLED display justifies the investment for their specific needs.

You are on a roller coaster and enter a loop, traveling on the inside of the loop. You pull positive Gs. What provides the centripetal force to make you move in a circle?
Answer:
While traveling on the inside of the loop, you will pull positive Gs and acceleration provides the centripetal force that pushes you against your roller coaster seat.
Explanation:
Due to acceleration, centripetal force keep roller coasters on their tracks and people in their seats. Centripetal force points to the inside of the loop and the car needs to travel fast in order to apply enough centripetal acceleration the roller coaster entering the loop.
When the cars are on the track, gravity pulls downward at a constant magnitude, but as it speeds up almost at the top of the loop, it and the track add together with the centripetal force.

Answer:
Explanation:
There is a web application where we compress text with some symbols.
For example:
A simple example can be
aaaaaaaaaaaaaaaaa = ☀
But we can make more complex example
☂☃☄☀ = hola
If we use this same rule, we can compress more long sentence
h = ☂
o = ☃
l = ☄
a = ☀
☂☃☄☀_☀_t☃d☃_e☄_mund☃_est☃y_☀qui_p☀r☀_c☃mprimir_text☃
Without the compress
hola_a_todo_el_mundo_estoy_aqui_para_comprimir_texto
Even we can make this compress with entire words
☀_☉_★_☊_☂_☈_☇_☆_☃_☄ = hola a todo el mundo estoy aqui para comprimir texto .
Compressed text size: 19 bytes
Original text size: 52 bytes
The rule is:
hola = ☀
mundo = ☂
comprimir = ☃
texto = ☄
todo = ★
para = ☆
aqui = ☇
estoy = ☈
a = ☉
el = ☊
