Explanation:
Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database.And The ACID properties, in totality, provide a mechanism to ensure correctness and consistency of a database in a way such that each transaction is a group of operations that acts a single unit, produces consistent results, acts in isolation from other operations and updates that it makes are durably stored.
1. What is memory mapped I/O?
Answer:
Memory-mapped I/O and port-mapped I/O are two complementary methods of performing input/output between the central processing unit and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own instructions.
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.

Draw a Card. Write a program to simulate drawing a card. Your program will randomly select one card from a deck of 52 playing cards. Your program should display the rank (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King) and suit (Clubs, Diamonds, Hearts, Spades) of the card. Here is a sample run of the program: in The card you picked is Jack of Heart The program should use at a minimum: sequence, selection, arrays, and random numbers.
Answer:
Explanation:
The following code is written in Java. It is a function that creates a Random object to generate random values, then uses those values to choose a random rank and suit using switch statements. It then saves the rank and suit into a String variable in the correct format and finally prints the card that was picked to the screen. The function was called 4 times in the main method and the output can be seen in the attached image below.
public static void randomCardGenerator() {
Random rand = new Random();
int rank = rand.nextInt(14)+1;
int suit = rand.nextInt(4)+1;
String chosenCard = "";
switch (rank) {
case 1: chosenCard += "Ace"; break;
case 2: chosenCard += "1"; break;
case 3: chosenCard += "2"; break;
case 4: chosenCard += "3"; break;
case 5: chosenCard += "4"; break;
case 6: chosenCard += "5"; break;
case 7: chosenCard += "6"; break;
case 8: chosenCard += "7"; break;
case 9: chosenCard += "8"; break;
case 10: chosenCard += "9"; break;
case 11: chosenCard += "10"; break;
case 12: chosenCard += "Jack"; break;
case 13: chosenCard += "Queen"; break;
case 14: chosenCard += "Kind"; break;
default: System.out.println("Wrong Value");
}
chosenCard += " of ";
switch (suit) {
case 1: chosenCard += "Clubs"; break;
case 2: chosenCard += "Diamonds"; break;
case 3: chosenCard += "Hearts"; break;
case 4: chosenCard += "Spades"; break;

You've arrived on site to a WAN installation where you will be performing maintenance operations. You have been told the WAN protocol in use allows multiple Layer 3 protocols and uses routers that use labels in the frame headers to make routing decisions. What WAN technology is in use
Answer:
The answer is "MPLS".
Explanation:
The MPLS stands for Multiprotocol Label Switching. This packet switching method facilitates the generation of easier personal backbones using a less physical channel, which sends information from one source to its destination with labels rather than IP addresses. Many of these WAN services are sold through huge companies. It is also a technology for data transfer that boosts speed and regulates network traffic flow. The information is directed with this technology via a label rather than needing complicated surveys at every stop in a route cache.
9.18 LAB: Exact change - methods Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is:
Answer:
Explanation:
The following code is written in Java. It asks the user to enter the amount of change needed. This is done as a double since we are dealing with coins and not full dollar values alone. It then makes the necessary calculations to calculate the number of each coin needed and outputs it back to the user. A test case has been provided in the picture below with a sample output.
import java.util.Scanner;

public static void main(String[] args) {
int dollars = 1;
double quarters = 0.25;
double dimes = 0.10;
double nickels = 0.05;
double pennies = 0.01;
Scanner in = new Scanner(System.in);
System.out.println("Enter Change Value: ");
double change = in.nextDouble();
int numDollars, numQuarters, numDimes, numNickels, numPennies;
double newChange;
numDollars = (int) (change / dollars);
newChange = change % dollars;
numQuarters = (int) (newChange / quarters);
newChange = newChange % quarters;
numDimes = (int) (newChange / dimes);
newChange = newChange % dimes;
numNickels = (int) (newChange / nickels);
newChange = newChange % nickels + 0.001;
numPennies = (int) (newChange / pennies);
newChange = newChange % pennies;
System.out.println("Minimum Num of Coins needed: ");
if (numDollars != 1) {
System.out.println(numDollars + " Dollars");
} else {
System.out.println(numDollars + " Dollar");
}
if (numQuarters != 1) {
System.out.println(numQuarters + " Quarters");
} else {

Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()).
Ex: If the input is:
2011
18000
2018
where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is:
Car's information:
Model year: 2011
Purchase price: 18000
Current value: 5770
Note: printInfo() should use three spaces for indentation.
Answer and Explanation:
public class Main {
int Carmodel;
int Purchaseprice;
int Currentyear;
Public void setPurchasePrice(int Purchaseprice){
this.Purchaseprice=Purchaseprice;
}
Public void getPurchasePrice(){
return Purchaseprice;
}
static void printInfo(int Carmodel int Currentyear ){
this.Carmodel=Carmodel;
this.Currentyear=Currentyear;
System.out.println(getPurchasePrice() Carmodel Currentyear);
}
}
The above java program defines a class that has three methods, a get method that returns purchase price of the object, a set method that sets purchase price of the object, and a print method that print out the information about the car object(model, year, price). The print method also takes arguments and assigns values of the arguments/parameters to the object, then prints all.
Select the correct statement(s) regarding 4B5B encoding.
a. 4B5B is used to map four codeword bits into a five bit data word
b. 4B5B information bit rate is 80% of the total (information plus overhead) bit rate
c. 4B5B information bit rate is 20% of the total (information plus overhead) bit rate
d. all statements are correct
Answer:
b. 4B5B information bit rate is 80% of the total information plus overhead bit rate.
Explanation:
4B5B bit rate encoding means there is 80% of the bit rate which included all the information plus the overheads. There is 20% of lack in bit rate due to encoding code words which converts data into smaller bits.
Your network has four Hyper-V hosts, which are running three domain controllers and about 10 member servers.

When implementing a 1:1 relationship, where should you place the foreign key if one side is mandatory and one side is optional? Should the foreign key be mandatory or optional?
Answer:
When implementing a 1:1 relationship, the foreign key should be placed on the optional side if one side is mandatory and one side is optional.
When this is implemented, the foreign key should be made mandatory.
Explanation:
A foreign key (FK) is a primary key (PK) in relational databases. It is used to establish a relationship with a table that has the same attribute with another table in the database. A mandatory relationship exists when the foreign key depends on the parent (primary key) and cannot exist without the parent. A one-to-one relationship exists when one row in a data table may be linked with only one row in another data table.

Write a recursive function that calculates the sum 11 22 33 ... nn, given an integer value of nin between 1 and 9. You can write a separate power function in this process and call that power function as needed:
Answer:
The function in Python is as follows:
def sumDig(n):
if n == 1:
return 11
else:
return n*11 + sumDig(n - 1)
Explanation:
This defines the function
def sumDig(n):
This represents the base case (where n = 1)
if n == 1:
The function returns 11, when it gets to the base case
return 11
For every other value of n (n > 1)
else:
This calculates the required sum recursively
return n*11 + sumDig(n - 1)

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:
Follows are the complete question to the given question:
Explanation:
The UML scheme is a UML-based diagram intended to depict the system visually, together with its key actors, roles, activities, objects, and classes, to gather information the about system, change that, or maintain it.
Every complex process is better understood via sketches or pictures. These diagrams have a higher understanding effect. By glancing about, we notice that diagrams are not a new idea but are widely used in various business types. To enhance understanding of the system, we prepare UML diagrams. There is not enough of a single diagram to represent all aspects of the system. You can also create customized diagrams to satisfy your needs. Iterative and incremental diagrams are usually done.
There are two broad diagram categories and that they are broken into subclasses again:

what is the data type name for integer?
Answer:
the data type name for integer is int
Hope This Helps!!!
Explanation:
the integer data type ( int ) is used to represent whole numbers that can be stored within 32-bits. The big integer data type ( bigint ) is used to represent whole numbers that are outside the range of the integer data type and can be stored within 64 bits.Write a java program that reads a list of integers and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is:
5 2 4 6 8 10
the output is:
10,8,6,4,2,
To achieve the above, first read the integers into an array. Then output the array in reverse.
Answer:
Explanation:
using namespace std;
#include <iostream>
int Go()
{
int N;
int A[20];
cout << " How many integers do you have ??? :>";
cin >> N;
if (N>20) { N=20; }
for (int iLoop=0; iLoop<N; iLoop++)
{
cout << "Input integer # " << (iLoop+1) << " :>";
cin >> A[iLoop];
}
for (int iLoop=N-1; iLoop>=0; iLoop--)
{
cout << A[iLoop] << " ";
}
cout << endl;
}
int main()
{
Go();
}
A Java program that reads a list of integers and outputs them in reverse is written as,
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end
}
}
Given that,
Write a Java program that reads a list of integers and outputs those integers in reverse.
Here, The input begins with an integer indicating the number of integers that follow.
For coding simplicity, follow each output integer by a comma, including the last one.
So, A Java program that reads a list of integers and outputs them in reverse:
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end
}

Code an operation class called ArrayComputing that will ask user to enter a serials of integers with a loop until -99 is entered and after the input it will keep and display the greatest, the least, the sum and the average of the data entries (-99 is not counted as the data). And code a driver class called ArrayComputingApp to run and test the ArrayComputing class, separately.
Must use required/meaningful names for fields, variables, methods and classes.
Must use separate methods to perform each of specified tasks as described.
Must document each of your source code
Answer:
Explanation:
The following is written in Java and creates the ArrayComputing class. It uses the constructor to create the infinite loop that only breaks when the user enters a -99. After every input number it goes adding the correct values to the variables. Once it is done the user can call any of the getter methods to get the variable values as well as calculate the average.
import java.util.Scanner;
class ArrayComputingApp {
public static void main(String[] args) {
ArrayComputing arrayComputing = new ArrayComputing();
System.out.println("Average: " + arrayComputing.getAverage());
System.out.println("Greatest: " + arrayComputing.getGreatest());
System.out.println("Least: " + arrayComputing.getLeast());
System.out.println("Sum: " + arrayComputing.getSum());
}
}
class ArrayComputing {
int greatest, least, sum, average;
int count = 0;
Scanner in = new Scanner(System.in);
public ArrayComputing() {
while (true) {
System.out.println("Enter a number or -99 to exit: ");
int num = in.nextInt();
if (num == -99) {
break;
}
if (num > this.greatest) {
this.greatest = num;
}
if (this.count == 0) {
this.least = num;
} else {
if (num < this.least) {
this.least = num;
}
}
this.sum += num;
this.count += 1;
}
}
public int getAverage() {
this.average = sum / count;
return this.average;
}
public int getGreatest() {
return greatest;
}
public int getLeast() {
return least;
}
public int getSum() {
return sum;
}
}
