Question 1:
The Wayfinder is an ancient piece of technology created as a means of navigating challenging stretches of space. The device connects to every piece of technology in the galaxy in order to detect planets and spaceships and then shown their location to the user. As it happens, locations of planets follow a specific distribution. A planet can exist at coordinates x,y only if
2x² + |2xy| + y² =10000
The user can use the Wayfinder to find nearby planets by input the range for x and y. Draw a flowchart and write a C++ program that models the Wayfinder. Ask the user to input a range for x and y, then print all possible planet coordinates. The program should also print the number of planets detected.
Hint: you can use pow(x,n) to get the value of xn and abs(x) to get the absolute value of x.
helpppppppppp!!!!!!!!!!
Sample output:
Answer:
Following are the code to the given question:
#include<iostream>//header file
#include<math.h>//header file
using namespace std;
int main()//main method
{
long long x, x1, y, y1;//defining long variable
int count=0,i,j;//defining integer variable
cout<<"Enter a range for x coordinates: "<<endl;//print message
cin>>x>>x1;//input x and x1 value
cout<<"Enter a range for y coordinates: "<<endl;//print message
cin>>y>>y1; //input y and y1 value
for(i = x; i <= -x1; i++)//use nested loop that tests each coordinates
{
for(j = y; j <= y1; j++)//use nested loop that tests each coordinates
{
if(((2*pow(i,2)) + abs(2*i*j) + pow(j,2)) == 10000)//use if that checks condition as per the given question
{
cout<<"There is a planet at "<<i<<", "<<j<<endl;// print coordinates
count++;//incrementing count variable value
}
}
}
cout<<"Total number of planets detected are: "<<count<<endl;//print count value
return 0;
}
Explanation:
In this code, inside the main method long "x, x1, y, and y1" and integer "count, i, and j" type variable is declared that uses a long variable to input value from the user-end.
In the next step, two nested loops have defined that test each coordinate and define if block that checks condition as per the given question and use i, j, and count variable to print value with the message.
Write a complete Java program called Rooter that gets a positive integer called "start" from the user at the command line and then finds the squareroot of every number from "start" down to 0. Use a while loop to count down. Print each square root on a separate line. Include data validation to ensure the user provides a positive integer. Assume that the user enters an integer, and for validation, just check to be sure it is positive. If the validation is not passed, provide the user with suitable feedback and stay in the program to let the user try again until valid input is received. Use the Math.sqrt(double a) method to find each square root.
Answer:
The program in Java is as follows:
import java.util.*;
import java.lang.Math;
public class Rooter{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int start;
System.out.print("Start: ");
start = input.nextInt();
while(start<=0){
System.out.print("Number must be positive\nStart: ");
start = input.nextInt(); }
while(start>=0){
System.out.println(Math.sqrt(start));
start--; }
}
}
Explanation:
This declares start as integer
int start;
This prompts the user for input
System.out.print("Start: ");
This gets input for start
start = input.nextInt();
The following is repeated until the user input is valid i.e. positive
while(start<=0){
System.out.print("Number must be positive\nStart: ");
start = input.nextInt(); }
The following while loop prints the square root of each number till 0
while(start>=0){
System.out.println(Math.sqrt(start));
start--; }
You work as a computer technician for a production company that travels all over the world while filming and editing music videos. Due to the nature of video editing, you will be building a video production workstation for the company that will have the maximum amount of RAM, an 8-core CPU, a dedicated GPU, and a redundant array of solid state devices for storage. You are now determining which power supply to install in the system. What is the MOST important characteristic to consider when choosing a power supply
Answer: Input Voltage
Explanation:
Based on the information given, since the power supply to install in the system is being determined, the input voltage is the most important characteristic to consider when choosing a power supply.
The input voltage indicates the type of voltage and the electrical current that's required to power a device safely and effectively.
You have just assembled your first PC. You hit the power button and the computer turns on. As the computer runs through POST, it starts beeping multiple times and you don't see anything displayed on the LCD. You notice there are no activity lights flashing for the HDD. However, when you check the inside of the computer, you can hear the drive spinning up. What is the NEXT thing you are going to check in order to get the PC functioning
Answer:
Explanation:
If the HDD is spinning, this means that the power cable is correctly connected and that the drive is receiving power and powering on. However, this does not mean that the HDD is functioning correctly and reading the information. Therefore, the next logical step would be to check the SATA cable that connects the drive to the motherboard. The cable may be broken or maybe the SATA slot on the motherboard. Switch out the cables and plug it into another slot. If this does not work, then it may be that the HDD is broken. Multiple Beeps can also mean that the RAM or CPU is not plugged in correctly or broken.

The part (or statement) of a recursive function that decides whether the recursive loop is terminated is called: (Select all that apply)
Answer:
The base case
Explanation:
Required
The part that determines the termination of a recursion
This part of a recursion is referred to as the base case.
Take for instance, the following:
factorial(int n) {
if (n < = 1) { return 1; }
else { return n*factorial(n-1); } }
The base case of the above is if (n < = 1) { return 1; }
Because the recursion will continue to be executed until the condition is true i.e. n less than or equals 1

1,list all data from table customer, sale and product. 2,list Name and sex of all customer. 3,list all male customer. 4,list all male and female customer. 5,list the name and age of male customers. 6,list the name, price and color of the product.
Answer:
The SQL queries are as follows:
1. select * from customer
select * from sale
select * from product
2. select name, sex from customer
3. select * from customer where sex = 'male'
4. select name, age from customer where sex = 'male'
5. select name, price, color from product
Explanation:
Given
Tables: customer, sale, product
Required
Answer question 1 to 5
(1) All data in the given tables
To do this, we make use of the select clause to retrieve data from each of the table and * to select all data.
So, we have:
select * from customer --> This lists all data from customer table
select * from sale --> This lists all data from sale table
select * from product --> This lists all data from product table
(2) Selected details from customer table
In (1), we have:
select * from customer --> This lists all data from customer table
To retrieve selected details, we replace * with the field names.
So, we have:
select name, sex from customer
(3) Male customers
In (1), we have:
select * from customer --> This lists all data from customer table
To retrieve male customers, we introduce the where clause
So, we have:
select * from customer where sex = 'male'
(4) Name and age of male customers
In (3), we have:
select * from customer where sex = 'male'
To retrieve the name and age, we replace * with name and age. So, we have:
select name, age from customer where sex = 'male'
(5) Name, price and color of products
In (1), we have:
select * from product --> This lists all data from product table
To retrieve selected details, we replace * with the field names.
So, we have:
select name, price, color from product
We made a distinction between the forwarding function and the routing function performed in the network layer. What are the key differences between routing and forwarding
Answer: forwarding: move packets from router's input to appropriate router output
routing: determine route taken by packets from source to destination
Explanation:
The network layer refers to where connections take place in the internet communication process by sending packets of data between different networks.
The distinction between the forwarding function and the routing function performed in the network layer is that the forwarding function move packets from the input of the router to the appropriate router output while the routing function:m helps in knowing the routee taken by packets from the source to destination.
Which access control type would you use to grant permissions based on the sensitivity of the information contained in the objects

Mandatory Access Control (MAC) is a means of restricting access to system resources based on the sensitivity (as represented by a label) of the information contained in the system resource and the formal authorization (i.e., clearance) of users to access information of such sensitivity.
What is the bit pattern (raw binary) of the single precision representation of the decimal number 0.125 following IEEE 754 standard
Answer:
The three elements that make up the number's 32 bit single precision IEEE 754 binary floating point representation:
Sign (1 bit) = 0 (a positive number)
Exponent (8 bits) = 0111 1100
Mantissa (23 bits) = 000 0000 0000 0000 0000 0000
Explanation:
1. First, convert to the binary (base 2) the integer part: 0.
Divide the number repeatedly by 2.
Keep track of each remainder.
We stop when we get a quotient that is equal to zero.
division = quotient + remainder;
0 ÷ 2 = 0 + 0;
2. Construct the base 2 representation of the integer part of the number.
Take all the remainders starting from the bottom of the list constructed above.
0(10) = 0(2)
3. Convert to the binary (base 2) the fractional part: 0.125.
Multiply it repeatedly by 2.
Keep track of each integer part of the results.
Stop when we get a fractional part that is equal to zero.
#) multiplying = integer + fractional part;
1) 0.125 × 2 = 0 + 0.25;
2) 0.25 × 2 = 0 + 0.5;
3) 0.5 × 2 = 1 + 0;
4. Construct the base 2 representation of the fractional part of the number.
Take all the integer parts of the multiplying operations, starting from the top of the constructed list above:
0.125(10) =
0.001(2)
5. Positive number before normalization:
0.125(10) =
0.001(2)
6. Normalize the binary representation of the number.
Shift the decimal mark 3 positions to the right so that only one non zero digit remains to the left of it:
0.125(10) =
0.001(2) =
0.001(2) × 20 =
1(2) × 2-3
7. Up to this moment, there are the following elements that would feed into the 32 bit single precision IEEE 754 binary floating point representation:
Sign: 0 (a positive number)
Exponent (unadjusted): -3
Mantissa (not normalized): 1
8. Adjust the exponent.
Use the 8 bit excess/bias notation:
Exponent (adjusted) =
Exponent (unadjusted) + 2(8-1) - 1 =
-3 + 2(8-1) - 1 =
(-3 + 127)(10) =
124(10)
9. Convert the adjusted exponent from the decimal (base 10) to 8 bit binary.
Use the same technique of repeatedly dividing by 2:
division = quotient + remainder;
124 ÷ 2 = 62 + 0;
62 ÷ 2 = 31 + 0;
31 ÷ 2 = 15 + 1;
15 ÷ 2 = 7 + 1;
7 ÷ 2 = 3 + 1;
3 ÷ 2 = 1 + 1;
1 ÷ 2 = 0 + 1;
10. Construct the base 2 representation of the adjusted exponent.
Take all the remainders starting from the bottom of the list constructed above:
Exponent (adjusted) =
124(10) =
0111 1100(2)
11. Normalize the mantissa.
a) Remove the leading (the leftmost) bit, since it's allways 1, and the decimal point, if the case.
b) Adjust its length to 23 bits, by adding the necessary number of zeros to the right.
Mantissa (normalized) =
1 000 0000 0000 0000 0000 0000 =
000 0000 0000 0000 0000 0000
12. The three elements that make up the number's 32 bit single precision IEEE 754 binary floating point representation:
Sign (1 bit) = 0 (a positive number)
Exponent (8 bits) = 0111 1100
Mantissa (23 bits) = 000 0000 0000 0000 0000 0000

Which of these collections defines a LIST? ["apple", "banana", "cherry"] {"apple", "banana", "cherry"} {"name": "apple", "color": "green"} ("apple", "banana", "cherry") Next ❯
Answer:
["apple", "banana", "cherry"]
Explanation:
In programming lists are defined by using square brackets. Curly brackets are used to define sets or dictionaries. Dictionaries are similar to lists but are not really considered lists since they use a key: value system unlike lists. Parenthesis in programming are used to define tuples or in some languages object literals with curly brackets inside. A list uses only square brackets, and depending on the language can either contain elements of the same type of different types. Therefore, the only correct example of a LIST in this question would be
["apple", "banana", "cherry"]
Program design tools. __________ uses English-like statements to outline the logic of a computer program. __________ graphically shows the step-by-step actions a computer program will take.
Answer:
Pseudocode; flowchart.
Explanation:
Pseudocode uses English-like statements to outline the logic of a computer program. A pseudocode gives a summary of the steps adopted during a software development process using simple (concise) words and symbols.
A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
Basically, a flowchart make use of standard symbols such as arrows, rectangle, diamond and an oval to graphically represent the steps associated with a system, process or workflow sequentially i.e from the beginning (start) to the end (finish).
The organization will most likely ___ to an internal user attempting to escalate privilege than to an external hacker
Answer:
respond differently.
Explanation:
NIST is acronym for National Institute of Standards and Technology and it's under the U.S. Department of Commerce. The NIST cybersecurity framework (CSF) is a powerful tool that provide guidelines for both the external and internal stakeholders of organization on how they can effectively and efficiently organize, manage, and improve their cybersecurity programs, so as to mitigate the risks associated with cybersecurity.
The NIST SP 800 30 is a risk mitigation framework that provide guidance for conducting or allows scope for research, assessment and acknowledgement for risk mitigation of federal information systems and organizations.
Typically, NIST SP 800 30 is used for translating cyber risk so that it can easily be understood by the chief executive officer (CEO) and board of both a public and private organization.
An organization is expected to most likely respond differently to an internal user such as one of its employees that attempt to escalate his or privilege than to an external hacker.
This is usually so because the organization trust its internal users to an extent than it does with external users or an attacker such as an external hacker.
