A student registers for a course in a university. Courses may have limited enrollment i.e a student must
enroll atmost 9 credit hours, the registration process must include checks that places are available. Assume
that the student accesses an electronic course catalog to find out about available courses. Which design
model should be followed by this secenario? Draw any two UML diagrams.
Answers
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:

Answers
Answer:
Following are the code to the given question:
#include <iostream>//defining header file
#include <vector>//defining header file
#include <numeric>//defining header file
using namespace std;
int main()//main method
{
vector<int> countDown(0);//defing an integer array variable countDown
int newSize = 0;//defing an integer variable newSize that holds a value 0
int i = 0;//defing an integer variable i that initialize with 0
newSize = 3;// //use newSize to hold a value
countDown.resize(newSize,0);// calling the resize method that accepts two parameters
for (i = 0; i < newSize; ++i)//defining a loop that reverse the integer value
{
countDown[i] = newSize -i;//reverse the value and store it into countDown array
cout << countDown.at(i) << " ";//print reverse array value
}
cout << "Go!" << endl;//print message
return 0;
}
Output:
3 2 1 Go!
Explanation:
In the given code inside the main method an integer array "countDown" and two integer variables "newSize and i" is declared that initializes a value that is 0.
In the next step, an array is used that calls the resize method that accepts two parameters, and define a for a loop.
In this loop, the array is used to reverse the value and print its value with the message.

Answers
Answer:
f. None of the above
Explanation:
Considering the available options, the right answer is option F "None of the above."
Common factors for database management system selection are the following:
1. Cost: various DBMS vendors have different pricing, hence, interested buyers will consider the price before selections
2. Features and Tools: different types of DBMS have varied features and tools in carrying out the work.
3. Software requirements: there are various software requirements in various DBMS, such as encryption support, scalability, application-level data recovery, etc.
4. Hardware requirement: various DBMS vendors have different hardware requirements to consider, such as sizeable RAM, CPU value, etc.
Hence, in this case, the correct answer is option F.
g 1-4 Which piece of network hardware breaks a network up into separate collision domains within a single broadcast domain
Answers
Answer:
A switch
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a hub, a router, printer, a switch, etc.
In computer networking, a switch is a network hardware (device) that breaks up a network into separate collision domains within a single broadcast domain. Thus, it's commonly configured with virtual local area network (VLAN) to break up and interconnect multiple networks.

Create and configure databases in oracle database management system operation administration
Answers
Answer:
You typically create a database during Oracle Database software installation. However, you can also create a database after installation.
Reasons to create a database after installation are as follows:
You used Oracle Universal Installer (OUI) to install software only, and did not create a database. You want to create another database (and database instance) on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database. You can also create the database in a new Oracle home by running OUI again. You want to make a copy of (clone) a database.
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)
Answers
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));

ii. How do the first three security concepts relate to these four attacks
Answers
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.

I would prefer to use an integrated router, switch, and firewall configuration for a home network instead of operating my home devices as separate systems.

Operating your home devices as separate systems does not offer the required good service in information sharing. To share the internet connection among the home devices, thereby making it cheaper for family members to access the internet with one Internet Service Provider (ISP) account rather than multiple accounts, a home network is required. A home network will always require a network firewall to protect the internal/private LAN from outside attack and to prevent important data from leaking out to the outside world.

total = 0
for i in range(len(numbers)):
if i != 3:
total+=numbers[i]
print(total)
Explanation:
This initializes the list
numbers = [10,20,30,40,50,60,100]
Set total to 0
total = 0
This iterates through numbers
for i in range(len(numbers)):
This ensures that the index 3, are not added
if i != 3:
total+=numbers[i]
Print the calculated sum
