Answer:
All of the above.
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
Hence, the operating system (OS) provides utility software designed to perform specific tasks. Some of the tasks it performs are;
A. Establishing an Internet connection.
B. Coordinating tasks between programs.
C. Configuring peripheral devices.
D. Monitoring security.
Write an application that counts the total number of spaces contained in a quote entered by the user.
Answer:
Explanation:
The following code is written in Java. It asks the user for an input and saves it in a String variable. Then it loops through all the characters in the string and counts the spaces. Finally, it prints the total number of spaces in the String.
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter Line Now:");
String userInput = in.nextLine();
int spaceCount = 0;
for (int x = 0; x < userInput.length(); x++) {
if (userInput.charAt(x) == ' ') {
spaceCount++;
}
}
System.out.println(spaceCount);
}
For Questions 1-4, consider the following code:
def mystery1(x):
return x + 2
def mystery2(a, b = 7):
return a + b
#MAIN
n = int(input("Enter a number:"))
ans = mystery1(n) * 2 + mystery2 (n * 3)
print(ans)
What is output when the user enters 9?
Answer:
9 would be entered as a parameter n of class mystery1 and return 9 + 2 = 11 and then 11 * 2 = 22, PLUS,
mystery2 new parameter is 9 * 3 = 27, then 27 + 7 = 34 returned
FINALLY, ans = 22 + 34
ans = 56 printed as output
Write a function named power that accepts two parameters containing integer values (x and n, in that order) and recursively calculates and returns the value of x to the nth power.
Answer:
Following are the code to the given question:
int power(int x, int n)//defining a method power that accepts two integer parameters
{
if (n == 0)//defining if block to check n equal to 0
{
return 1; //return value 1
}
else//defining else block
{
x = x * power(x, --n); //use x variable to call method recursively
}
return x; //return x value
}
Explanation:
In the above-given code, a method power is defined that accepts two integer variable in its parameter, in the method a conditional statement is used which can be defined as follows:
In the if block, it checks "n" value, which is equal to 0. if the condition is true it will return value 1.In the else block, an integer variable x is defined that calls the method recursively and return x value.What term refers to a sequence of statements in a language that both humans and computers can understand?

9.2.2: Output formatting: Printing a maximum number of digits. Write a single statement that prints outsideTemperature with 4 digits. End with newline. Sample output with input 103.45632: 103.5
Answer:
The single print statement that does the required in python is:
print("%.4g" % outsideTemperature)
Explanation:
The full program is as follows:
The first line prompts user for input
outsideTemperature = float(input("Outside Temperature: "))
To print significant figures, we make use of g formats. And this is implemented as follows:
print("%.4g" % outsideTemperature)
The above prints 4 significant digits of outsideTemperature
For other significant figures, simply change the 4 to another number
Write a program that contains three methods:
Method max (int x, int y, int z) returns the maximum value of three integer values.
Method min (int X, int y, int z) returns the minimum value of three integer values.
Method average (int x, int y, int z) returns the average of three integer values.
Answer:
#include <stdio.h>//defining header file
int max (int x, int y, int z) //defining a method max that hold three parameters
{
if(x>=y && x>=z)//defining if block that checks x is greater then y and x is greater then z
{
return x;//return the value x
}
else if(y>z)//defining else if block it check y is greater then z
{
return y;//return the value y
}
else//else block
{
return z;//return the value z
}
}
int min (int x, int y, int z) //defining a method max that holds three parameters
{
if(x<=y && x<=z) //defining if block that check x value is less then equal to y and less then equal to z
{
return x;//return the value of x
}
if(y<=x && y<=z) //defining if block that check y value is less then equal to x and less then equal to z
{
return y;//return the value of y
}
if(z<=x && z<=x)//defining if block that check z value is less then equal to x
{
return z;//return the value of z
}
return x;//return the value of z
}
int average (int x, int y, int z) //defining average method that take three parameters
{
int avg= (x+y+z)/3;//defining integer variable avg that calculate the average
return avg;//return avg value
}
int main()//defining main method
{
int x,y,z;//defining integer variable
printf("Enter first value: ");//print message
scanf("%d",&x);//input value from the user end
printf("Enter Second value: ");//print message
scanf("%d",&y);//input value from the user end
printf("Enter third value: ");//print message
scanf("%d",&z);//input value from the user end
printf("The maximum value is: %d\n", max(x,y,z));//calling the method max
printf("The minimum value is: %d\n", min(x,y,z));//calling the method min
printf("The average value is: %d\n", average(x,y,z));//calling the method average
return 0;
}
Output:
Enter first value: 45
Enter Second value: 35
Enter third value: 10
The maximum value is: 45
The minimum value is: 10
The average value is: 30
Explanation:
In the above-given code, three methods "max, min, and average" is declared that holds three integer variable "x,y, and z" as a parameter and all the method work as their respective name.
In the max method, it uses a conditional statement to find the highest number among them.In the min method, it also uses the conditional statement to find the minimum value from them.In the average method, it defined an integer variable "avg" that holds the average value of the given parameter variable.In the main method, three variable is defined that inputs the value from the user end and passes to the method and print its value.HELP URGENTLY!!!!!

What is the most vulnerable information that should be protected to prevent unauthorized access to your online files and records?
Answer:
Your user ID and password.
Explanation:
The user Id and password must be protected because when it is exposed to a third party then they can get access to information, data, to things they are not supposed to.
The user Id and password is provided as an authentication measure for one to be able to gain access to a computer system, network or files. It is what grants access to online files and record as it is the case here. It has to be protected for the sake of privacy.
Write a function named findmax()that finds and displays the maximum values in a two dimensional array of integers. The array should be declared as a 10 row by 15 column array of integers in main()and populated with random numbers between 0 and 100.
Answer:
import java.util.*;
public class Main
{
public static void main(String[] args) {
Random r = new Random();
int[][] numbers = new int[10][15];
for (int i=0; i<10; i++){
for (int j=0; j<15; j++){
numbers[i][j] = new Random().nextInt(101);
}
}
for (int i=0; i<10; i++){
for (int j=0; j<15; j++){
System.out.print(numbers[i][j] + " ");
}
System.out.println();
}
findmax(numbers);
}
public static void findmax(int[][] numbers){
int max = numbers[0][0];
for (int i=0; i<10; i++){
for (int j=0; j<15; j++){
if(numbers[i][j] > max)
max = numbers[i][j];
}
}
System.out.println("The max is " + max);
}
}
Explanation:
*The code is in Java.
Create a function called findmax() that takes one parameter, numbers array
Inside the function:
Initialize the max as first number in the array
Create a nested for loop that iterates through the array. Inside the second for loop, check if a number is greater than the max. If it is set it as the new max
When the loop is done, print the max
Inside the main:
Initialize a 2D array called numbers
Create a nested for loop that sets the random numbers to the numbers array. Note that to generate random integers, nextInt() function in the Random class is used
Create another nested for loop that displays the content of the numbers array
Call the findmax() function passing the numbers array as a parameter
