Answer: 52
Explanation:
Following the information given in the question, we are informed that a process needs 103 KB of memory in order to run and that the system on which it is to run uses paging with 2KB pages, then the number of frames in memory that are needed will be:
= 103/2
= 51.5
= 52 approximately
Therefore, 52 frames in memory are needed.
Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect. Submit the code of the program and your comments on the execution of the program.
Answer:
Following are the code to the given question:
import java.util.concurrent.*; //import package
public class Threads //defining a class Threads
{
private Integer s = new Integer(0);//defining Integer class object
public synchronized static void main(String[] args)//defining main method
{
Threads t = new Threads();//defining threads class object
System.out.println("What is sum ?" + t.s);//print value with message
}
Threads()//defining default constructor
{
ExecutorService exe = Executors.newFixedThreadPool(1000);//defining ExecutorService class object
System.out.println("With SYNCHRONIZATION........");//print message
for(int i = 1; i <= 1000; i++)//defining a for loop
{
exe.execute(new SumTask2());//calling execute method
System.out.println("At Thread " + i +" Sum= " + s + " , ");//print message with value
}
exe.shutdown();//calling shutdown method
while(!exe.isTerminated())//defining while loop that calls isTerminated method
{
}
}
class SumTask2 implements Runnable//calling SumTask2 that inherits Runnable class
{
public synchronized void run()//defining method run
{
int value = s.intValue() + 1;//defining variable value that calls intvalue which is increment by 1
s = new Integer(value);//use s to hold value
}
}
}
Output:
Please find the attached file.
Explanation:
In this code, a Threads class is defined in which an integer class object and the main method is declared that creates the Threads class object and calls its values.
Outside the method, the default constructor is declared that creates the "ExecutorService" and prints its message, and use a for loop that calls execute method which prints its value with the message.
In the class, a while loop is declared that calls "isTerminated" method, and outside the class "SumTask2" that inherits Runnable class and defined the run method and define a variable "value" that calls "intvalue" method which is increment by 1 and define s variable that holds method value.

Assume that an O(log2N) algorithm runs for 10 milliseconds when the input size (N) is 32. What input size makes the algorithm run for 14 milliseconds
Answer:
An input size of N = 128 makes the algorithm run for 14 milliseconds
Explanation:
O(log2N)
This means that the running time for an algorithm of length N is given by:
[tex]F(N) = c\log_{2}{N}[/tex]
In which C is a constant.
Runs for 10 milliseconds when the input size (N) is 32.
This means that [tex]F(32) = 10[/tex]
So
[tex]F(N) = c\log_{2}{N}[/tex]
[tex]10 = c\log_{2}{32}[/tex]
Since [tex]2^5 = 32, \log_{2}{32} = 5[/tex]
Then
[tex]5c = 10[/tex]
[tex]c = \frac{10}{5}[/tex]
[tex]c = 2[/tex]
Thus:
[tex]F(N) = 2\log_{2}{N}[/tex]
What input size makes the algorithm run for 14 milliseconds
N for which [tex]F(N) = 14[/tex]. So
[tex]F(N) = 2\log_{2}{N}[/tex]
[tex]14 = 2\log_{2}{N}[/tex]
[tex]\log_{2}{N} = 7[/tex]
[tex]2^{\log_{2}{N}} = 2^7[/tex]
[tex]N = 128[/tex]
An input size of N = 128 makes the algorithm run for 14 milliseconds
let's have a class named Distance having two private data members such as feet(integer), inches(float), one input function to input values to the data members, one Display function to show the distance. The distance 5 feet and 6.4 inches should be displayed as 5’- 6.4”. Then add the two objects of Distance class and then display the result (the + operator should be overloaded). You should also take care of inches if it's more than 12 then the inches should be decremented by 12 and feet to be incremented by 1.

{
// call the function installApplication
}
void installApplication(char appInitial, int appVersion)
{
// rest of function not important
}
Select one:
A.
int x =installApplication(‘A’, 1);
B.
installApplication(‘A’, 1);
C.
int x= installApplication( );
D.
installApplication(2 , 1);
Answer:
B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct

Explain the following terms.
a) Explain Final keyword with example. b) Define Static and Instance variables
Answer:
A.
the final keyword is used to denote constants. It can be used with variables, methods, and classes. Once any entity (variable, method or class) is declared final , it can be assigned only once.
B.
Static variables are declared in the same place as instance variables, but with the keyword 'static' before the data type. While instance variables hold values that are associated with an individual object, static variables' values are associated with the class as a whole.

Answer:
Dynamic Router
Explanation:
A dynamic router is a network connection device that can build tables that identify addresses on each network.
What is Dynamic network?Dynamic networks are networks that vary over time; their vertices are often not binary and instead represent a probability for having a link between two nodes.
Statistical approaches or computer simulations are often necessary to explore how such networks evolve, adapt or respond to external intervention.
DNA statistical tools are generally optimized for large-scale networks and admit the analysis of multiple networks simultaneously in which, there are multiple types of nodes (multi-node) and multiple types of links (multi-plex).
Therefore, A dynamic router is a network connection device that can build tables that identify addresses on each network.

A. Malicious code.
B. Hoaxes.
C. Spoofing.
D. Sniffer.
Answer:
C. Spoofing.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.
Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.

*11.13 (Remove duplicates) Write a method that removes the duplicate elements from
an array list of integers using the following header:
public static void removeDuplicate(ArrayList list)
Write a test program that prompts the user to enter 10 integers to a list and displays
the distinct integers separated by exactly one space. Here is a sample run:
Enter ten integers: 34 5 3 5 6 4 33 2 2 4
The distinct integers are 34 5 3 6 4 33 2
Answer:
The program in Java is as follows:
import java.util.*;
public class Main {
public static void removeDuplicate(ArrayList<Integer> list){
ArrayList<Integer> newList = new ArrayList<Integer>();
for (int num : list) {
if (!newList.contains(num)) {
newList.add(num); } }
for (int num : newList) {
System.out.print(num+" "); } }
public static void main(String args[]){
Scanner input = new Scanner(System.in);
ArrayList<Integer> list = new ArrayList<Integer>();
System.out.print("Enter ten integers: ");
for(int i = 0; i<10;i++){
list.add(input.nextInt()); }
System.out.print("The distinct integers are: ");
removeDuplicate(list);
}}
Explanation:
This defines the removeDuplicate function
public static void removeDuplicate(ArrayList<Integer> list){
This creates a new array list
ArrayList<Integer> newList = new ArrayList<Integer>();
This iterates through the original list
for (int num : list) {
This checks if the new list contains an item of the original list
if (!newList.contains(num)) {
If no, the item is added to the new list
newList.add(num); } }
This iterates through the new list
for (int num : newList) {
This prints every element of the new list (At this point, the duplicates have been removed)
System.out.print(num+" "); } }
The main (i.e. test case begins here)
public static void main(String args[]){
Scanner input = new Scanner(System.in);
This declares the array list
ArrayList<Integer> list = new ArrayList<Integer>();
This prompts the user for ten integers
System.out.print("Enter ten integers: ");
The following loop gets input for the array list
for(int i = 0; i<10;i++){
list.add(input.nextInt()); }
This prints the output header
System.out.print("The distinct integers are: ");
This calls the function to remove the duplicates
removeDuplicate(list);

Consider the following class in Java:
public class MountainBike extends Bicycle {
public int seatHeight;
public MountainBike(int startHeight,
int startCadence,
int startSpeed,
int startGear) {
super(startCadence, startSpeed, startGear);
seatHeight = startHeight;
}
public void setHeight(int newValue) {
seatHeight = newValue;
}
}
What is this trying to accomplish?
super(startCadence, startSpeed, startGear);
a. Four fields of the MountainBike class are defined: super, startCadence, startSpeed and startGear.
b. The constructor for the parent class is called.
c. A method of the MountainBike class named super is defined.
d. Three fields are defined for the MountainBike class as intances of the class named super.
Answer:
b. The constructor for the parent class is called.
Explanation:
In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.
