Explain briefly the FIREWALLS

Answer:

128 KB      

Explanation:

Given data :

The block size = 512 bytes

Block pointer size = 2 bytes

In an indexed allocation, a special block named Index Block contains all the pointers to the blocks that the file had occupied.

Therefore, the maximum number of block pointer in 1 block :

[tex]$=\frac{\text{block size}}{\text{pointer size}}$[/tex]

[tex]$=\frac{512}{2}$[/tex]

= 256

Thus, a block can hold maximum 256 pointers.

It is given the level of indexing is one. So,

Maximum size of the file =  maximum number of block pointers in 1 file x block size

                                          = 256 x 512

                                          [tex]$=2^8 \times 2^9$[/tex]

                                          [tex]$=2^{8+9}$[/tex]

                                           [tex]$=2^{17}$[/tex]

                                          [tex]$=2^7 \times 2^{10}$[/tex]

                                          [tex]$=128 \times 2^{10}$[/tex]

                                          = 128 KB   (∵ 1 KB = [tex]2^{10} \ B[/tex] )

Therefore, the largest file that 1 level if indexed allocation method can handle is 128 KB.

Which XXX declares a student's name.

public class Student {

   XXX

   private double myGPA;  

   private int myID;

   public int getID() {

        return myID;

   }

}

Group of answer choices

a. String myName;

b. public String myName;

c. private myName;

d. private String myName;

private String myName;

To declare a student's name, the following should be noted.

i. The name of the student is of type String

ii. Since all of the instance variables (myGPA and myID) have a private access modifier, then myName (which is the variable name used to declare the student's name) should be no exception. In other words, the student's name should also have a private access.

Therefore, XXX which declares a student's name should be written as

private String myName;

Option (a) would have been a correct option if it had the private keyword

Option (b) is not the correct option because it has a public access rather than a private access.

Option (c) is not a valid syntax since, although it has a private access, the data type of the variable myName is not specified.

Option (d) is the correct option.

The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int quantity = 0;

       double subtotal = 0;

       double tax, grandTotal;

       while (true) {

           System.out.println("Enter a price: ");

           double price = in.nextDouble();

           if (price == 0) {

               break;

           } else if (price > 0) {

               quantity += 1;

               subtotal += price;

           }

       }

       tax = subtotal * 0.075;

       grandTotal = subtotal + tax;

       System.out.println("Quantity: $" + quantity);

       System.out.println("Subtotal: $" + subtotal);

       System.out.println("Tax: $" + tax);

       System.out.println("GrandTotal: $" + grandTotal);

The modified program in Python is as follows:

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))  

for i in range(triangle_height):

   print(triangle_char * (i+1))

Explanation:

This gets the character from the user

triangle_char = input('Enter a character:\n')

This gets the height of the triangle from the user

triangle_height = int(input('Enter triangle height:\n'))  

This iterates through the height

for i in range(triangle_height):

This prints extra characters up to the height of the triangle

   print(triangle_char * (i+1))

Here's the modified program that incorporates the requested changes:

python

Copy code

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))

print('')

for i in range(1, triangle_height + 1):

   line = triangle_char * i + ' ' * (triangle_height - i)

   print(line)

This program uses a loop to iterate from 1 to triangle_height. In each iteration, it creates a line by concatenating triangle_char repeated i times with spaces (' ') repeated (triangle_height - i) times. The resulting line is then printed.

For example, if the user enters % as the character and 5 as the height, the output will be to make sure to maintain the indentation properly in your code for it to work correctly.

Answer:

DCUKE

Explanation:

Given that,

Code for JAVA = LCXC

To find,

Code for BASIC = ?

As we observe the pattern,

In "JAVA", every letter moved two-letter forward in their alphabetical order or we can say that every third alphabet of the given letter is used to make the code:

J + 2 = L

A + 2 = C

V + 2 = X

A + 2 = C

Similarly,

B + 2 = D

A + 2  = C

S + 2 = U

I + 2  = K

C + 2 = E

Thus, DCUKE is the code for BASIC.

The code for BASIC given the code for JAVA is; DCUKE

We are given the code for JAVA as LCXC

From that code for "JAVA", we see that every letter is moved forward two letters in their alphabetical order. This means

Similarly for BASIC;

Thus, finally the code for BASIC is DCUKE
