public static void main(String args[]){ //start of main function
Scanner scan = new Scanner(System.in); // creates Scanner class object
System.out.print("Please enter a number: "); //prompts user to enter an int n for the number of rows
int n = scan.nextInt(); //reads and scans the value of n from user
int i, j; //declares two variables to iterate through i rows and j columns
for (i=1; i<=n; i++){ //outer loop for rows
for (j=2*(n-i); j>=1; j--){ //inner loop for space between numbers in pattern
System.out.print(" "); } //displays an empty space in the pattern
for (j = i; j >= 1; j--) { //inner loop for columns
System.out.print(j+" "); } //prints the value of j (prints numbers in reverse)

Which of the following statement about device formatting is FALSE?
A) Device manufacturers store the initial file-system data structures in the device.
B) Operating system can create multiple partitions with in a single device.
C) Volume creation is implicit when a file system is placed directly within a partition.
D) Not every partition contains a copy of the operating systems.
Answers
Answer:
The correct option is;
A) Device manufacturers store the initial file-system data structures in the device.
Explanation:
Before a storage device can be used for data storage, it is required to prepare the device for use and to make the device to become visible to the operating system by formatting of the device
New storage devices are not pre-formatted or come with a ready to use file system as there are different file systems specifically designed for particular operating systems or operating environment.
Formatting creates partitions, makes the hard drive visible to the operating system and creates a file system that is new such that the storage device can be used for storing files.

The single greatest physical threat to information systems is:
Sabotage
Explanation:
Sabotage describes the efforts of internal persons to ensure that a system does not operate as intended or is destroyed. Among the threats to information systems, this is the greatest. The problem with sabotage is that the operators are internal, they know the system very well. They understand the weak points and the strengths of the system. They are internal terrorists to any information system. These internal saboteurs are capable of using any means to achieve their purpose. Therefore, it is necessary to scrutinize employees from time to time to discover internal risks.

Write a program that prompts the user to input an integer that represents the money in cents. The program will the calculate the smallest combination of coins that the user has. For example, 42 cents is 1 quarter, 1 dime, 1 nickel, and 2 pennies. Similarly, 49 cents is 1 quarter, 2 dimes, and 4 pennies
Answers
Answer:
The program in Python is as follows:
cents = int(input("Cent: "))
quarter = int(cents/25)
if quarter > 1:
print(str(quarter)+" quarters")
elif quarter == 1:
print(str(quarter)+" quarter")
cents = cents - quarter * 25
dime = int(cents/10)
if dime>1:
print(str(dime)+" dimes")
elif dime == 1:
print(str(dime)+" dime")
cents = cents - dime * 10
nickel = int(cents/5)
if nickel > 1:
print(str(nickel)+" nickels")
elif nickel == 1:
print(str(nickel)+" nickel")
penny = cents - nickel * 5
if penny > 1:
print(str(penny)+" pennies")
elif penny == 1:
print(str(penny)+" penny")
Explanation:
This line prompts user for input in cents
cents = int(input("Cent: "))
This line calculates the number of quarters in the input amount
quarter = int(cents/25)
This following if statement prints the calculated quarters
if quarter > 1:
print(str(quarter)+" quarters")
elif quarter == 1:
print(str(quarter)+" quarter")
cents = cents - quarter * 25
This line calculates the number of dime in the input amount
dime = int(cents/10)
This following if statement prints the calculated dime
if dime>1:
print(str(dime)+" dimes")
elif dime == 1:
print(str(dime)+" dime")
cents = cents - dime * 10
This line calculates the number of nickels in the input amount
nickel = int(cents/5)
This following if statement prints the calculated nickels
if nickel > 1:
print(str(nickel)+" nickels")
elif nickel == 1:
print(str(nickel)+" nickel")
This line calculates the number of pennies in the input amount
penny = cents - nickel * 5
This following if statement prints the calculated pennies
if penny > 1:
print(str(penny)+" pennies")
elif penny == 1:
print(str(penny)+" penny")
Discuss the main characteristics of the database approach and how it differs from traditional file systems.
Answers
The database system allows the creation of a single depository of information, which is updated periodically and which can be used simultaneously by many users, since this type of system allows the effective sharing of all data stored in its depository . In addition, this is a secure system and is very difficult to break into. This is because of the efficiency of the software used to maintain it. However, the use of these softwares can be a little complicated for users, in addition to requiring a high economic cost to obtain them.
The traditional file system, in turn, each user must obtain their own file related to the application they want to run. This may seem dull in comparison to the database, but it is advantageous as it does not require any spending on software, as it is simple and there are several cheap and efficient tools and editors on the market. However, this system is not so safe, it can cause isolation of data and even data inconsistency, which disrupts the entire system.

__________ _____-_____.
Answers
Answer:
Technical know-how
Explanation:
Write a program to compute answers to some basic geometry formulas. The program prompts the user to input a length (in centimeters) specified as a floating point value. The program then echoes the input and computes areas of squares and circles and the volume of a cube. For the squares, you will assume that the input length value is the length of a side. For the circles, this same value becomes the diameter. Use the meter value input to calculate the results in square (or cubic) meters and then print the answers in square (or cubic) meters.
Answers
Answer:
import math
l = float(input("Enter length in cm: "))
l = l / 100;
print("Entered length is " + str(l) + " meters")
area_square = l * l
print("Area of square is " + str(area_square))
area_circle = math.pi * l/2 * l/2
print("Area of circle is " + str(area_circle))
volume_cube = l * l * l
print("Volume of cube is " + str(volume_cube))
Explanation:
*The code is in Python
Ask the user to enter the length in cm
Convert the length to meters and print it
Calculate the area of the square and print it (Since length is equal to a side, the area is length * length)
Calculate the area of the circle and print it (Since length is equal to the diameter, you need to divide it by two to get the radius. The area is pi * length/2 * length/2)
Calculate the volume of the cube and print it (Since length is equal to a side, the volume is length * length * length)

Fonts can be defined as a graphical representation of texts which includes a collection of characters such as numbers, letters, symbols etc in various size, color, typeface, design or weight.
A general rule for printing is to use sans-serif fonts for headlines and serif fonts for body text. This ultimately implies that, for any printed work such as novels, books, newspapers etc, it is a general rule for a printer to use sans-serif fonts for headlines and serif fonts for body text in order to enhance readability.
Also, it can be reversed in some instances by using a serif font for headlines and a sans-serif font for the body of a text.
