Answer:
The not strong security methods are:
a. Disabling SSID
b. WPS
Explanation:
When you disable SSID, you only make your Wi-Fi secure for the less determined attackers. By disabling the SSID (network name), those who are less technically inclined are prevented from connecting to the network but, this will not deter a more determined and technically savvy adversary. The best two options are MAC filtering and setting encryption. WPS (Wi-Fi Protected Setup) enables the process of connecting to a secure wireless network from a computer or other device easier instead of making it harder.
a. Download the attached �Greetings.java� file.
b. Implement the �getGreetings� method, so that the code prompts the user to enter the first name, the last name, and year of birth, then it returns a greetings message in proper format (see the example below). The �main� method will then print it out. Here is an example dialogue with the user:
Please enter your first name: tom
Please enter your last name: cruise
Please enter your year of birth: 1962
Greetings, T. Cruise! You are about 50 years old.
Note that the greetings message need to be in the exact format as shown above (for example, use the initial of the first name and the first letter of the last name with capitalization).
c. Submit the final �Greetings.java� file (DO NOT change the file name) online.
Answer:
Code:
import java.util.*;
public class Greetings
{
public static void main(String[] args)
{
Scanner s = new Scanner(System.in);
System.out.println(getGreetings(s));
}
private static String getGreetings(Scanner console)
{
System.out.print("Please enter your first name: ");
String firstName=console.next();
char firstChar=firstName.toUpperCase().charAt(0);
System.out.print("Please enter your last name: ");
String lastName=console.next();
lastName=lastName.toUpperCase().charAt(0)+lastName.substring(1, lastName.length());
System.out.print("Please enter your year of birth: ");
int year=console.nextInt();
int age=getCurrentYear()-year;
return "Greetings, "+firstChar+". "+lastName+"! You are about "+age+" years old.";
}
private static int getCurrentYear()
{
return Calendar.getInstance().get(Calendar.YEAR);
}
}

How does a computer work? Explain with an example.
Answer:
A computer system works by combining input, storage space, processing, and output. ... For example, when we type something using a keyboard, it is known as an Input provided to the Computer. Storage Space: It is the place where our input gets stored. It is known as Computer Memory that keeps the data into it.
Write the code for the following problem.
Add a function to problem to display the last name and highest, last name and lowest and average exam score. Hint: for highest initialize a variable to 0 (high_var). If the array value is higher than the high_var then set high_var to the array value and set high_index to the position of the array. Proceed through the array until you get to the end. Do the same for finding the lowest using low_var set to 999 (higher than the highest value). For the average score, sum all the exam scores as you proceed through the loop. Use a for loop to go through each occurrence of the arrays. Note you can do all this with one for loop but if it makes more sense to you to use multiple for loops that is ok too.

You are the network administrator for the ABC Company. Your network consists of two DNS servers named DNS1 and DNS2. The users who are configured to use DNS2 complain because they are unable to connect to internet websites. The following shows the configuration of both servers:
Server Configurations:
DNS1: _msdcs.abc.comabc.com
DNS2: .(root)_msdcs.abc.comabc.com
The users connected to DNS2 need to be able to access the internet. What should be done?
Answer:
ABC Company
The action to take is to:
Delete the .(root) zone from the DNS2. Then configure conditional forwarding on the DNS2 server. If this is not done, the users will be unable to access the internet.
Explanation:
DNS forwarding enables DNS queries to be forwarded to a designated server, say DNS2, for resolution according to the DNS domain name. This stops the initial server, DNS1, that was contacted by the client from handling the query, thereby improving the network's performance and resilience and enabling the users to be connected to the DNS2 in order to access the internet.
At the Greene City Interiors branch office, you have been asked to implement an IP network. Your network ID is currently192.168.1.0/24. You need to divide this in half network (two subnets) to accommodate hosts on two separate floors of the building, each of which is served by managed switches. The whole network is served by a single router.
Based on the above scenario, answer the following questions:
1. To divide the network in half, what subnet mask do you need to use?
2. What are the subnet IDs for each network?
3. Your manager is not satisfied with the new subnet scheme and wants to reduce the number of subnets to make more hosts and addresses available in each subnet. Is there a way to use the same subnet for the two floors of the office?

As the first step, load the dataset from airline-safety.csv by defining the load_data function below. Have this function return the following (in order):
1. The entire data frame
2. Total number of rows
3. Total number of columns
def load_data():
# YOUR CODE HERE
df, num_rows, num_cols
Answer:
import pandas as pd
def load_data():
df = pd.read_csv("airline-safety.csv')
num_rows = df.shape[0]
num_cols = df.shape[1]
return df, num_rows, num_cols
Explanation:
Using the pandas python package.
We import the package using the import keyword as pd and we call the pandas methods using the dot(.) notation
pd.read_csv reads the csv data into df variable.
To access the shape of the data which is returned as an array in the format[number of rows, number of columns]
That is ; a data frame with a shape value of [10, 10] has 10 rows and 10 columns.
To access the value of arrays we use square brackets. With values starting with an index of 0 and so on.
The row value is assigned to the variable num_rows and column value assigned to num_cols

how to not addUse methods to: 1. Get a String from the user at the command line 2. Populate an ArrayList of Character data (the wrapper class), with each char in the String represented as a separate Character element in the ArrayList 3. Output each Character to the command line, each on a separate line space into my array list
Answer:
Explanation:
The following code is written in Java. It asks the user to enter a string. Then the program loops through the string and separates the string into an ArrayList of characters. Finally, it outputs each character separately on a its own line.
import java.util.ArrayList;
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a String: ");
String answer = in.nextLine();
ArrayList<Character> charsList = new ArrayList<>();
for (int i = 0; i < answer.length(); i++) {
charsList.add(answer.charAt(i));
}
for (char x: charsList) {
System.out.println(x);
}
}

The trackpad/touchpad on my laptop is acting unusual. When I click on something or move to an area, it jumps or moves to another area. What would be a good troubleshooting step to try and resolve this issue?
a. Use a mouse instead
b. Remove all possible contact points, and test again while ensuring only a single contact point
c. Refer caller to user guides
d. increase the brightness of the display
Answer:
My best answer would be, "b. Remove all possible contact points, and test again while ensuring only a single contact point"
This is because usually when the cursor jumps around without reason, it's caused by the user accidentally hitting the mouse touchpad on his or her laptop while typing. ... Similarly, know that just because you have an external mouse attached to your laptop, the built-in mousepad is not automatically disabled.

Hi ! How can you return the value of the class computeDiscountInfo to the variable savings in the main class ?
Here is my code :
import java.util.Scanner;
public class RoomCost{
public static void main (String [] args){
double price;
double discount;
double savings;
Scanner keyboard = new Scanner(System.in);
System.out.print("Enter cutoff price for discount $>> ");
price = keyboard.nextDouble();
System.out.print("Enter discount rate as a whole number >> ");
discount = keyboard.nextDouble();
displayinfo();
//insert code to set the value returned from computeDiscountInfo method to savings);
// savings =
System.out.println("Special this week on any room over " + price);
System.out.println("Discount of " + discount + " percent");
System.out.println("That's a savings of at least $" + savings);
}
public static void displayinfo(){
System.out.println("We want your stay to be memorable.");
System.out.println("We promise to make you as comfortable as possible.");
}
public static double computeDiscountInfo(double price, double discountRate)
{
double savings;
//(insert code to calculate savings as price multiplied by discount divided by 100);
savings = (price * discountRate)/100;
return savings;
}
}
Answer:
savings = computeDiscountInfo(price, discount);
Explanation:
First of all computeDiscountInfo is a function, not a class.
You can call this function and assign its return value to a variable, savings in this example.
Genevieve is a student who attends classes at a campus downtown. She likes to study in the college's coffee shop, where she often accesses the Internet through the college's wireless network. Which network type is Genevieve using
Answer:
I'll let you make an educated guess off of this info! You always retain info better making an inference on a subject that you are having trouble with!
Explanation:
There are four types of wireless networks -- wireless local area networks, wireless metropolitan area networks, wireless personal area networks and wireless wide area networks -- each with its own function.
wireless local area networkA wireless local area network (WLAN) is a wireless distribution method for two or more devices. WLANs use high-frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection.
wireless metropolitan area networkA metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN).
wireless personal area networkA PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway.
wireless wide area networkWireless wide area network (WWAN), is a form of wireless network. ... WWAN connectivity allows a user with a laptop and a WWAN card to surf the web, check email, or connect to a virtual private network (VPN) from anywhere within the regional boundaries of cellular service.
I hope this helped!!
