Answer:
In the early 1900s, military moved their resources to distant locations with the help of trains, ships, and, to a lesser extent, horse-drawn wagons. This was so because at that time airplanes did not yet exist, capable of transporting inputs to any part of the world in a very short period of time. Therefore, inputs and resources were brought by sea and, if impossible, through land, using railways or highways.
Cardinality ratios often dictate the detailed design of a database. The cardinality ratio depends on the real-world meaning of the entity types involved and is defined by the specific application. For the binary relationships below, suggest cardinality ratios based on the common-sense meaning of the entity types. Clearly state any assumptions you make.
Entity 1 Cardinality Ratio Entity 2
1. Student SocialSecurityCard
2. Student Teacher
3. ClassRoom Wall
4. Country CurrentPresident
5. Course TextBook
6. Item (that can
be found in an
order) Order
7. Student Class
8. Class Instructor
9. Instructor Office
10. E-bay Auction item E-bay bid
Solution :
ENTITY 1 CARDINALITY RATIO ENTITY 2
1. Student 1 to many Social security card
A student may have more than one
social security card (legally with the
same unique social security number),
and every social security number belongs
to a unique.
2. Student Many to Many Teacher
Generally students are taught by many
teachers and a teacher teaches many students.
3.ClassRoom Many to Many Wall
Do not forget that the wall is usually
shared by adjacent rooms.
4. Country 1 to 1 Current President
Assuming a normal country under normal
circumstances having one president at a
time.
5. Course Many to Many TextBook
A course may have many textbooks and
text book may be prescribed for different
courses.
6. Item Many to Many Order
Assuming the same item can appear
in different orders.
7. Student Many to Many Class
One student may take several classes.
Every class usually has several students.
8. Class Many to 1 Instructor
Assuming that every class has a unique
instructor. In case instructors were allowed
to team teach, this will be many-many.
9. Instructor 1 to 1 Office
Assuming every instructor has only one
office and it is not shared. In case of offices
shared by 2 instructors, the relationship
will be 2-1. Conversely, if any instructor has a joint
appointment and offices in both departments,
then the relationship will be 1-2. In a very general
case, it may be many-many.
10. E-bay Auction item 1-Many E-bay bid
1 item has many bids and a bid is unique
to an item.
A recursive method may call other methods, including calling itself. Creating a recursive method can be accomplished in two steps. 1. Write the base case -- Every recursive method must have a case that returns a value or exits from the method without performing a recursive call. That case is called the base case. A programmer may write that part of the method first, and then lest. There may be multiple base cases.Complete the recursive method that returns the exponent of a given number. For e.g. given the number 5 and the exponent 3 (53) the method returns 125. Note: any number to the zero power is 1. Note: Do not code for the example. Your method must work for all given parameters! Use this as your method header: public static int raiseToPower(int base, int exponent)
Answer:
Explanation:
The following code is written in Java. It creates the raiseToPower method that takes in two int parameters. It then uses recursion to calculate the value of the first parameter raised to the power of the second parameter. Three test cases have been provided in the main method of the program and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
System.out.println("Base 5, Exponent 3: " + raiseToPower(5,3));
System.out.println("Base 2, Exponent 7: " + raiseToPower(2,7));
System.out.println("Base 5, Exponent 9: " + raiseToPower(5,9));
}
public static int raiseToPower(int base, int exponent) {
if (exponent == 0) {
return 1;
} else if (exponent == 1) {
return base;
} else {
return (base * raiseToPower(base, exponent-1));
}
}
}
LAB: Count multiples (EO)
Complete a program that creates an object of the Count class, takes three integers as input: low, high, and x, and then calls the countMultiples() method. The countMultiples() method then returns the number of multiples of x between low and high inclusively.
Ex: If the input is:
1 10 2
countMutiples() returns and the program output is:
5
Hint: Use the % operator to determine if a number is a multiple of x. Use a for loop to test each number between low and high.
Note: Your program must define the method:
public int countMultiples(int low, int high, int x)
Count.java
1 import java.util.Scanner;
2
3 public class Count {
4
5 public int countMultiples(int low, int high, int x) {
6 /* Type your code here. */
7
8 }
9
10 public static void main(String[] args) {
11 Scanner scnr = new Scanner(System.in);
12 /* Type your code here. */
13 }
14)
15
Following are the Java Program to the given question:
import java.util.Scanner; //import package for user-input
public class Count //defining a class Count
{
public static int countMultiples(int low,int high,int x)//defining a method countMultiples that takes three integer parameters
{
int c=0,i; //defining integer variables that hold value

Your network has four Hyper-V hosts, which are running three domain controllers and about 10 member servers. Three of the member servers named HR1, HR2, and HR3 are running on a Windows Server 2012 R2 Hyper-V host; the others are running on Windows Server 2016 Hyper-V hosts. All VMs are running Windows Server 2016. You are currently running an enterprise human resources application on the HR1, HR2, and HR3 servers. You are considering upgrading this application to a new version that was recently released. Before you proceed with the upgrade, you set up a test environment consisting of a Windows Server 2016 Hyper-V host and three VMs. You haven't been using checkpoints on any of your VMs, but you want to start doing so as an extra form of disaster recovery in the event of VM corruption or errors introduced by updates. On your test environment, you want to use checkpoints while you are testing the new application. What type of checkpoints should you use throughout your live network and test network? Explain.

In the forward chaining technique, used by the inference engine component of an expert system, the _____ condition is evaluated first.
Answer:
"if" is the right response.
Explanation:
Forward chaining is being utilized just to split the logical sequential order down as well as operate throughout every component once the preceding one is accomplished, from start to finish.Its whole algorithm begins with proven information that activates all the rules, which are fulfilled as well as makes established realities even more complete.Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.
Answer:
The function in C++ is as follows:
int isSorted(int ar[], int n){
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
return isSorted(ar, n - 1);}
Explanation:
This defines the function
int isSorted(int ar[], int n){
This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
This checks if the current element is less than the previous array element; If yes, the array is not sorted
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
This calls the function, recursively
return isSorted(ar, n - 1);
}

In C language
In a main function declare an array of 1000 ints. Fill up the array with random numbers that represent the rolls of a die.
That means values from 1 to 6. Write a loop that will count how many times each of the values appears in the array of 1000 die rolls.
Use an array of 6 elements to keep track of the counts, as opposed to 6 individual variables.
Print out how many times each value appears in the array. 1 occurs XXX times 2 occurs XXX times
Hint: If you find yourself repeating the same line of code you need to use a loop. If you declare several variables that are almost the same, maybe you need to use an array. count1, count2, count3, count4, … is wrong. Make an array and use the elements of the array as counters. Output the results using a loop with one printf statement. This gets more important when we are rolling 2 dice.
Answer:
The program in C is as follows:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(){
int dice [1000];
int count [6]={0};
srand(time(0));
for (int i = 0; i < 1000; i++) {
dice[i] = (rand() %(6)) + 1;
count[dice[i]-1]++;
}
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n");
}
return 0;
}
Explanation:
This declares an array that hold each outcome
int dice [1000];
This declares an array that holds the count of each outcome
int count [6]={0};
This lets the program generate different random numbers
srand(time(0));
This loop is repeated 1000 times
for (int i = 0; i < 1000; i++) {
This generates an outcome between 1 and 6 (inclusive)
dice[i] = (rand() %(6)) + 1;
This counts the occurrence of each outcome
count[dice[i]-1]++; }
The following prints the occurrence of each outcome
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n"); }
g 1-1 Which network model layer provides information about the physical dimensions of a network connector like an RJ45
Answer:
Physical layer
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.
This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.
A security administrator currently spends a large amount of time on common security tasks, such aa report generation, phishing investigations, and user provisioning and deprovisioning This prevents the administrator from spending time on other security projects. The business does not have the budget to add more staff members.
Which of the following should the administrator implement?
A. DAC
B. ABAC
C. SCAP
D. SOAR
Answer: SOAR
Explanation:
SOAR (security orchestration, automation and response) refers to compatible software programs wfuvg allows an organization to collect data that has to do with security threats and also enables them respond to security events without the needs of a human assistance.
Since the administrator doesn't have time on other security projects, the SOAR will be vital in this regard.

Explanation:
what is the process by which we can control what parts of a program can acccess the members of class
Answer:
Encapsulation.
Explanation:
Information hiding involves using private fields within classes and it's a feature found in all object-oriented languages such as Java, Python, C#, Ruby etc.
In object-oriented programming language, a process known as encapsulation is used for the restrictions of the internal data of a software program from the outside code, therefore preventing an unauthorized direct access to the codes. This is achieved through the use of classes.
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.
Write a program that reads a list of words. Then, the program outputs those words and their frequencies. Ex: If the input is: hey hi Mark hi mark
Answer:
The program in Python is as follows:
wordInput = input()
myList = wordInput.split(" ")
for i in myList:
print(i,myList.count(i))
Explanation:
This gets input for the word
wordInput = input()
This splits the word into a list using space as the delimiter
myList = wordInput.split(" ")
This iterates through the list
for i in myList:
Print each word and its count
print(i,myList.count(i))
