Explanation:
which wireless technology does the fire alarm system use?
Wireless fire alarm systems get the signal from detectors to the control panel, which is transmitted by radio frequency. The heat detectors have thermistors that sense the heat in order for the alarm to go off. I hope this helps you out!
Why has information visualization become a centerpiece in business intelligence and analytics? Is there a difference between information visualization and visual analytics?
Answer:
explanation below
Explanation:
Information visualization helps in making and distributing business information that are profitable and this is the reason why it has become a centerpiece in business intelligence and analytics. It has also become very important in rapidly understanding difficult information.
Information visualization lays emphasis on data that is abstract, which is, data with no agreed-upon depiction. Examples of this are the financial data, statistics and text. Visual analytics, on its own, lays emphasis on analytical reasoning about data and then puts together the computational analysis techniques with interactive visualization.

Explanation:
Write the function max_int_in_list that takes a list of ints and returns the biggest int in the list. You can assume that the list has at least one int in it. A call to this function would look like:
my_list = [5, 2, -5, 10, 23, -21]
biggest_int = max_int_in_list(my_list)
# biggest_int is now 23
Do not use the built-in function max in your program!
Hint: The highest number in the list might be negative! Make sure your function correctly handles that case.
# your function should return the maximum value in `my_list`
def max_int_in_list(my_list):
highest = my_list[0]
for num in my_list:
if num > highest:
highest = num
return highest
my_list = [5, 2, -5, 10, 23, -21]
biggest_int = max_int_in_list(my_list)
print (biggest_int)

Follow the directions below to submit Assignment 2:
Create a Java program.
The class name for the program should be 'DecimalFloor'.
In the main method you should perform the following:
Create a Scanner object.
Input a decimal /double value using the Scanner object.
Convert the input decimal/double value to an integer value (this will drop the decimal from the decimal/double value input).
Output the decimal/double value input.
Output the double/decimal value after converting the integer value back to a decimal value.
Pseudo flowchart for the assignment program:
Create a Scanner object using the Scanner class found in the java.util package.
Output a prompt asking the using to input a decimal value.
Accept the input value into a variable capable of holding decimal values.
Convert the decimal value to an integer value. This will drop all the decimal positions to the right of the decimal.
Covert the integer value to a double value.
Output the initial decimal value input.
Output the double value from step 5.
Answer:
Explanation:
The following code is written in Java and performs every action requested in the question. Instead of converting back and forth it saves the decimal/double value in one variable and the integer value in another variable so both can easily be accessed and printed.
import java.util.Scanner;
public class DecimalFloor {
public static void main(String args[]) {
//Ask for input and place into variable decimalValue
Scanner in = new Scanner(System.in);
System.out.println("Input decimal value:");
double decimalValue = in.nextDouble();
//Rounding down decimalValue to integer
int integerValue = (int) Math.floor(decimalValue);
//Print both integerValue and decimalValue
System.out.println(integerValue);
System.out.println(decimalValue);
}

A user purchased a new smart home device with embedded software and connected the device to a home network. The user then registered the device with the manufacturer, setting up an account using a personal e-mail and password. Which of the following explains how a phishing attack could occur against the user of the smart home device?
A. A vulnerability in the device's software is exploited to gain unauthorized access to other devices on the user's home network.
B. A vulnerability in the device's software is exploited to install software that reveals the user's password to an unauthorized individual
C. The user is sent an e-mail appearing to be from the manufacturer, asking the user to confirm the account password by clicking on a link in the e-mail and entering the password on the resulting page.
D. The user's account is sent an overwhelming number of messages in an attempt to disrupt service on the user's home network.
Answer:
C. The user is sent an e-mail appearing to be from the manufacturer, asking the user to confirm account password by clicking on a link in the e-mail and entering password on the resulting page.
Explanation:
Phishing attack is a cyber atttack in which user is sent an email which he thinks is useful. When the user open the email and does as instructed in the email his account gets locked. His personal information is haccked and then rannsom is demanded to release that information. The hacckers usually steal credit card information and bank details of the user which are misused.
All of the following are true about data science and big data except: a.Digital data is growing at the rate of 2.5 quintillion bytes per day b.Data scientists use skills in data management, statistics, and software development c.No digital data is stored in traditional databases d.Data science involves preparing, manipulating, and analyzing large amounts of digital data
Answer:
Option C
Explanation:
All of the following are true about data science and big data except No digital data is stored in traditional databases
Reason -
Data generated in current time is of large size and is also complicated. Traditional data bases such as SQL databases etc. are not capable to store data that is changing at a fast pace and has huge volume, veracity, variety and velocity. But big data platforms such as Hadoop can store big data and process it speedily and easily.
Given the following class: Create a class MyGenerator that can be used in the below main method.
class Random{
public static void main(String [] args){
perform(new MyGenerator());
}
private static abstract class Generator {
protected abstract double getRandom();
}
public static void perform(T g){
System.out.println(g.getRandom());
}
}
Answer:
Explanation:
The below code shows the complete code for the project. we have used Math.random() as a means of generating a random double value in the getRandom() method since it is not specified.
class Random {
[tex]\ \ \ \ \ \ \ \ \mathbf{ public \ static \ void \ main \ (String[] \ args) \ \ \{}[/tex]
perform(new MyGenerator());
}
[tex]\mathbf{private \ static \ abstract \ class \ Generator \{ \ }[/tex]
[tex]\mathbf{ \ protected \ abstract \ double \ getRandom();}[/tex]
}
public static <T extends Generator> void perform(T g) {
[tex]\mathbf{System.out.println(g.getRandom());}[/tex]
}
// MyGenerator class inherited from Generator
public static class MyGenerator extends Generator {
// implementing abstract method getRandom() of Generator class
[tex]\mathbf{Override}[/tex]
[tex]\mathbf{protected \ double \ getRandom() \{ }[/tex]
//returning a single double value between 0.0 and 1.0
[tex]\mathbf{return \ Math.random();}[/tex]
}
}
}
/*OUTPUT (will be random)*/
0.53296649765
