Answer:
it would have to be flow control which would be C.
Explanation:
Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.
What is Flow Control?The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.
A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.
The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.
Thus, option C is correct.

6. Security: Security is a must-have for the client. Explain how to protect user information on and between various platforms. Consider the user protection and security capabilities of the recommended operating platform.>
Answer:
Here the answer is given as follows,
Explanation:
Operating Platform:-
In terms of platforms, there are differences between, mobile games and pc games within the way it's used, the operator, the most event play, the sport design, and even the way the sport work. we all know that each one the games on console platforms, PC and mobile, have their own characteristic which has advantages and disadvantages All platforms compete to win the rating for the sake of their platform continuity.
Operating system architectures:-
Arm: not powerful compared to x86 has many limitations maximum possibility on arm arch is mobile gaming.
X86: very powerful, huge development so easy to develop games on platforms like unity and unreal, huge hardware compatibility and support
Storage management:-
On the storage side, we've few choices where HDD is slow and too old even a replacement console using SSD. so SSD is the suggested choice. But wait SSD have also many options like SATA and nvme.
Memory management:-
As recommended windows, Each process on 32-bit Microsoft Windows has its own virtual address space that permits addressing up to 4 gigabytes of memory. Each process on 64-bit Windows features a virtual address space of 8 terabytes. All threads of a process can access its virtual address space. However, threads cannot access memory that belongs to a different process.
Distributed systems and networks:-
Network-based multi-user interaction systems like network games typically include a database shared among the players that are physically distributed and interact with each other over the network. Currently, network game developers need to implement the shared database and inter-player communications from scratch.
Security:-
As security side every game, there's an excellent risk that, within the heat of the instant, data are going to be transmitted that you simply better keep to yourself. There are many threats to your IT.
Define on the whole data protection matters when developing games software may cause significant competitive advantages. Data controllers are obliged under the GDPR to attenuate data collection and processing, using, as an example , anonymization or pseudonymization of private data where feasible.

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.
When a database stores the majority of data in RAM rather than in hard disks, it is referred to as a(n) _____ database.
Answer:
in-memory.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
In this context, data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.
Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.
All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.
Generally, when a database stores the majority of data in random access memory (RAM) rather than in hard disks, it is referred to as an in-memory database (IMDB).
An in-memory database (IMDB) is designed to primarily to store data in the main memory of a computer system rather than on a hard-disk drive, so as to enhance a quicker response time for the database management system (DBMS).

(d) for (int n=0; n < HEIGHT; n++) { for (int m=0; m < WIDTH; m++) { anArray[n][m] = 0; }}
Explanation:
Given
HEIGHT [tex]\to[/tex] rows
WIDTH [tex]\to[/tex] columns
Required
Fill the array with zeros
Assume the array has already been declared
First, we iterate through the rows; using:
for (int [tex]n=0[/tex]; [tex]n < HEIGHT[/tex]; [tex]n++[/tex]) {
Next, we iterate through the columns
for (int [tex]m=0[/tex]; [tex]m < WIDTH[/tex]; [tex]m++[/tex]) {
Then we fill the array with the iterating variables of rows and the columns
anArray[n][m]
Lastly, close the loops

Write a program named edit_data.py that asks a person their age. Accept an int. Use a custom exception to return a message if the number entered is an int that is less than 1 or greater than 115. Create an exception that catches an error if a non int is entered.
An error that occurs while a program is being run is an exception. Non-programmers see exceptions as examples that do not follow a general rule.
What is the programming?
In computer science, the term "exception" also has the following connotation: It signifies that the issue is an uncommon occurrence; it is the "exception to the rule." Some programming languages use the mechanism known as exception handling to deal with problems automatically. Exception handling is built into several programming languages, including C++, Objective-C, PHP, Java, Ruby, Python, and many others.
In order to manage errors, programs often save the state of execution at the time the problem occurred and interrupt their usual operation to run an exception handler, which is a particular function or section of code. Depending on the type of error that had occurred, the error handler can "correct" the issue and the application can then continue using the previously saved data.
Thus, An error that occurs while a program is being run is an exception.

Complete the calcAverage() method that has an integer array parameter and returns the average value of the elements in the array as a double.(Java program)
Ex: If the input array is:
1 2 3 4 5
then the returned average will be:
3.0
Answer:
Explanation:
The following Java program has the method calcAverage(). It creates a sum variable which holds the sum of all the values in the array and the count variable which holds the number of elements in the array. Then it uses a For Each loop to loop through the array and go adding each element to the sum variable. Finally it calculates the average by dividing the sum by the variable count and returns the average to the user. A test case has been created in the main method using the example in the question. The output can be seen in the image attached below.
class Brainly {
public static void main(String[] args) {
int[] myArr = {1, 2, 3, 4, 5};
System.out.println(calcAverage(myArr));
}
public static double calcAverage(int[] myArr) {

The manager of the Super Supermarket would like to be able to compute the unit price for products sold there. To do this, the program should input the name and price of an item per pound and its weight in pounds and ounces. Then it should determine and display the unit price (the price per ounce) of that item and the total cost of the amount purchased. You will need the following variables: ItemName Pounds Ounces PoundPrice TotalPrice UnitPriceYou will need the following formulas: UnitPrice = PoundPrice/16 TotalPrice = PoundPrice * (Pounds + Ounces/16)
Answer:
The program in Python is as follows:
name = input("Name of item: ")
PoundPrice = int(input("Pound Price: "))
Pounds = int(input("Weight (pounds): "))
Ounces = int(input("Weight (ounce): "))
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)
print("Unit Price:",UnitPrice)
print("Total Price:",TotalPrice)
Explanation:
This gets the name of the item
name = input("Name of item: ")
This gets the pound price
PoundPrice = int(input("Pound Price: "))
This gets the weight in pounds
Pounds = int(input("Weight (pounds): "))
This gets the weight in ounces
Ounces = int(input("Weight (ounce): "))
This calculates the unit price
UnitPrice = PoundPrice/16
This calculates the total price
TotalPrice = PoundPrice * (Pounds + Ounces/16)
This prints the unit price
print("Unit Price:",UnitPrice)
This prints the total price
print("Total Price:",TotalPrice)

Suppose that you write a subclass of Insect named Ant. You add a new method named doSomething to the Ant class. You write a client class that instantiates an Ant object and invokes the doSomething method. Which of the following Ant declarations willnot permit this? (2 points)I. Insect a = new Ant ();II. Ant a = new Ant ();III. Ant a = new Insect ();1) I only2) II only3) III only4) I and II only5) I and III only
Answer:
5) I and III only
Explanation:
From the declarations listed both declarations I and III will not permit calling the doSomething() method. This is because in declaration I you are creating a superclass variable but initializing the subclass. In declaration III you are doing the opposite, which would work in Java but only if you cast the subclass to the superclass that you are initializing the variable with. Therefore, in these options the only viable one that will work without error will be II.
