Answer:
A. Participate actively in
Explanation:
The brain starts to develop even before a child is born and continues into adulthood. During the first few first years of a child's life, neurons, synapses and axon are multiplied to millions. The child's learning process determines the neural connections to be cut off by pruning. An active connection is retained while inactive neurons, synapses and axons are eliminated.
As the child grows, neural connections are strengthened by active participation in the learning process. But when these connections are left idle, they tend to decay.
Final answer:
Actively participating in the learning process by using elaborative rehearsal, the self-reference effect, distributed practice, and repeated rehearsal creates strong neural networks. Employing mnemonic devices and sensory inputs enhances cognitive learning and the formation of semantic networks.
Explanation:
To create strong neural networks in the brain, one must participate actively in the learning process. Active participation encompasses techniques such as elaborative rehearsal, which involves deeply processing and linking new information to other information and memories, making it more meaningful. Employing the self-reference effect by making the material personal, using distributed practice to space out learning, and engaging in repeated rehearsal to ensure information moves from short-term to long-term memory are all strategies that contribute to stronger neural connections.
Other essential strategies include creating mental images, utilizing mnemonic devices, and engaging in activities that stimulate cognitive learning. This could involve drawing connections to past experiences, utilizing various sensory inputs, or creating visual representations to aid comprehension. It is important to note that memory techniques such as mnemonic devices, like acronyms and acrostics, can be particularly helpful for recalling information. Ultimately, the more connections one forms to a concept, the better they can remember it, as per the theory of spreading activation.
Encapsulation means ________. 1. that data fields should be declared private2. that a class can extend another class 3. that a variable of supertype can refer to a subtype object 4. that a class can contain another class
Answer:
Option 1 is the correct answer for the above question.
Explanation:
Encapsulation means rapper the data or variable or method on some pack and denies to give direct access for any private data. The above question wants to ask about the Encapsulation. The option 1 is correct for its because this option suggests a scenario, where a class field is declared as private and we know that private data members of the class can not be accessed by outside the class. It can access only the inside of the class. So it proves both the property of encapsulation one is to rapper the data and the other is to deny the directly accessed outside. So this option is correct while the other is not because--
Option 2 states that another class is extended by the base class which is not the property of encapsulation. Option 3 states that a sub-type object can be referred by the variable of super-type which is also not the property of encapsulation. Option 4 states that a class is contained by the other class which does not hold both the property of encapsulation.Write the function prototype for a function called showSquare. The function should have a single parameter variable of the int data type and a return type of void.
Answer:
void showSquare(int param){
}
Explanation:
In C++ programing language, this is how a function prototype is defined.
The function's return type (In this case Void)
The function's name (showSquare in this case)
The function's argument list (A single integer parameter in this case)
In the open and closing braces following we can define the function's before for example we may want the function to display the square of the integer parameter; then a complete program to accomplish this in C++ will go like this:
#include <iostream>
using namespace std;
void showSquare(int param);
int main()
{
showSquare(5);
return 0;
}
void showSquare(int param){
int square = param*param;
cout<<"The Square of the number is:"<<endl;
cout<<square;
}

12. Is Java compiled or interpreted (or both)? How do you know?
13. What is the difference between a compiler and a preprocessor?
14. What was the intermediate form employed by the original AT&T C++ compiler?
15. What is P-code? 16. What is bootstrapping? 17. What is a just-in-time compiler?
18. Name two languages in which a program can write new pieces of itself "on the fly."
19. Briefly describe three "unconventional" compilers—compilers whose purpose is not to prepare a high-level program for execution on a microprocessor.
20. List six kinds of tools that commonly support the work of a compiler within a larger programming environment.
21. Explain how an IDE differs from a collection of command-line tools.
Answer:
11: Compiler translates a high level source program into a target equivalent (machine language).
An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.
12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)
13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.
14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language
15: Stack-based language, similar to modern Java compiler byte code
16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.
17: A compiler which translates byte code into machine language immediately prior to each program execution.
18: Lisp and Prolog
19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.
21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.

QUESTION 4 A(n) _____________ is a set of rules that determine what a layer would do and provides a clearly defined set of messages that software at the layer needs to understand. a) agreement b) specification c) protocol d) regulation policy.
Answer:
Option c Protocol
Explanation:
A protocol is a set of rules that determine how communication end-points should follows to exchange information. The protocol defines the rules, syntax and semantics for communication. This means the communicated messages are also well-defined. Besides, the protocol can also include possible error recovery methods.
The protocol can be implemented by either software or hardware.
Answer:
(c) Protocol
Explanation:
A protocol specifies a set of rules governing what a layer would do including the set of messages that software at the layer would need to be able to interpret and understand. Protocols also specify how data is packaged and transmitted in a network.
For communication to occur between devices, these devices must conform to a particular language that they both understand. Hence, a protocol.
Examples of protocols are ;
i. Simple Mail Transfer Protocol (SMTP) for mailing services.
ii. HyperText Transfer Protocol (HTTP) for transferring files on the world wide web.
iii. File Transfer Protocol (FTP) for data and file transfer services between a client and a server on a network.
Authorization is the process of granting rights to use an organization's IT assets, systems, applications, and data to a specific user. True or false?
Answer:
True
Explanation:
In computing context, authorization is a process that grant a specific user to use the computer resources that can include both hardware and software. In some cases, authorization is also granted to access private-owned data. Usually, the authorization is implemented by having a user to entry username and password in order to log into a system to use the resources.
There might also be different level of authorization. Each specific user has different privileged level to use the resources. For example, a staff from finance department can access the corporate financial information but the same info is not available to other department staffs
Answer:
True
Explanation:
Usually preceded by authentication (which means confirming the identity of a user), authorization is the process of granting access level rights to a user to use an organization's resources such as IT assets, systems, applications, and files.
By access level rights, we mean that depending on the level of authority of the user, they can access certain resources. For example, a mere user (or a regular staff) in an organization, might not have some administrative privileges such as editing files which might be given to other users who are admins. In other words, authorization also means controlling what users access what resources.

You are the administrator for the CorpNet domain. The CorpDC and CorpDC3 servers are the DNS servers for the domain. You are responsible for CorpDC, which resides in Building A. Users report that they are unable to contact the CorpWeb server.
Complete the following:
1. Ping the CorpWeb server using its full name (CorpWeb.CorpNet.local). What happens?
2. Ping the CorpWeb server using its IP address (192.168.0.15). What happens?
3. Create any DNS records needed to fix the problem.
4. Use the Ping command to verify that the problem has been fixed.
Final answer:
To troubleshoot the DNS issue, first ping the CorpWeb server by name and then by IP. If only the name fails, create the correct DNS A record. Verify the solution with a final ping.
Explanation:
The inability to contact the CorpWeb server possibly indicates a DNS resolution issue. Here's how to troubleshoot and fix the problem:
Ping the CorpWeb server by its full name. If there is no response, this suggests a DNS resolution problem.
Ping the CorpWeb server by its IP address (192.168.0.15). If this is successful, it confirms that the issue lies with DNS rather than connectivity.
Create or correct the A record for CorpWeb in the DNS server. The A record should point the server's fully qualified domain name (FQDN) to its IP address.
Use the ping command again to verify that the DNS problem has been resolved and that CorpWeb.CorpNet.local now responds.
Final answer:
The issue with contacting the CorpWeb server can be addressed by checking DNS resolution through pinging the server by name and by IP address. A corrective action is to verify and create the necessary A record in DNS. Once the record is set, a successful ping by server name confirms resolution of the issue.
Explanation:
To address the issue where users are unable to contact the CorpWeb server, follow these troubleshooting steps:
Ping the CorpWeb server using its full name (CorpWeb.CorpNet.local). If the ping fails, it indicates that there may be a DNS resolution issue.
Ping the CorpWeb server using its IP address (192.168.0.15). If this ping is successful, it further confirms that there is a DNS problem, since the server is reachable by its IP address but not by its full name.
To fix the issue, log into the DNS management console on CorpDC and create or correct the A record for CorpWeb.CorpNet.local to point to the correct IP address, which is 192.168.0.15.
Finally, use the Ping command again to verify that the problem has been fixed. If the ping to CorpWeb.CorpNet.local is successful, then users should now be able to contact the CorpWeb server by its full name.

When working with arrays, most programming languages perform ________, which means they do not allow programs to use invalid subscripts. Group of answer choices
1. buffer overrun protection
2. None of these
3. bitwise data execution
4. array bounds checking subscript binding
Final answer:
In array operations, most programming languages use array bounds checking to prevent the use of invalid subscripts, ensuring memory safety.
Explanation:
When working with arrays, most programming languages perform array bounds checking, which means they do not allow programs to use invalid subscripts. The correct answer is option 4. Array bounds checking is a safety feature in many programming languages that prevents programs from accessing memory locations outside of the allocated array space.
This is important to prevent errors and potential vulnerabilities like buffer overruns, where an attacker could manipulate the program to execute arbitrary code by overwriting parts of the memory.

What can be controlled through IoT? Choose four answers.
Desktops
Door locks
Laptops
Light switches
Security cameras
Thermostat
Answer:
Door locks
Light switches
Security cameras
Thermostat
Explanation:
IoT is internet of things that means network of different things that are interconnected through internet and make the decision with the help of Electronic sensors. The sensor sense the data from environment at different times and send this to the cloud (that may be the server). On the basis of this data different devices such as door looks, light switches, security cameras and thermostat take decisions with the help of controllers and change their current state.
For Example
In case of door look, there may be sensor that is sensing the finger prints of the user and after recognizing the person the door will be unlock. If unauthenticated user will try to open the lock a message has been sent to concerned. The training data of the the authorized persons is saved on the cloud, whenever someone tries to access, the data from sensor and cloud send to controller for making comparison and decision. So we can say that Door lock can be controlled IoT.
In case of light switches, there are few sensor available to sense the intensity of life. Different training values of that sensors are stored on the cloud. Whenever these sensors sense the light intensity, they send the data to the cloud contentiously, whenever the data match with darkness intensity, a signal has been send from controller to the switch to ON the lights.
Same as in cameras and Thermostat both are sending data to the cloud and controller. With the help of different image processing techniques and sensor camera will take the decision related to face recognition. Thermostat devices are also on and off by variation of temperature.

Write a program that asks the user to enter ten temperatures and then finds the sum. The input temperatures should allow for decimal values. Sample Run Enter Temperature: 27.6 Enter Temperature: 29.5 Enter Temperature: 35 Enter Temperature: 45.5 Enter Temperature: 54 Enter Temperature: 64.4 Enter Temperature: 69 Enter Temperature: 68 Enter Temperature: 61.3 Enter Temperature: 50 Sum = 504.3
Answer:
#include <iostream>
#include <conio.h>
using namespace std;
main()
{
float temp[10], sum;
sum=0;
for (int i=1 ; i<= 10; i++)
{
cout<<"Enter the temperature in Decimal for temp"<<i<<"=";
cin>>temp[i];
}
for (int j=1 ; j<=10 ; j++)
{
sum = sum+temp[i];
}
cout<< "/nThe Total Temperature ="<<sum;
getch();
}
Explanation:
In this program we can take values of temperature in decimal values by taking the data type of temp variable as float. Array is used to enter the ten temperature values. Sum variable is used to add all the values.
The code example provided is a Python program that prompts the user to enter ten temperatures, validates the input as decimal values, accumulates the sum, and then prints out the total sum.
To write a program that asks the user to enter ten temperatures and then finds the sum, you would need a loop that runs ten times, prompting the user to input a temperature on each iteration. The program should allow for decimal values to be entered. Below is an example of how this can be implemented in Python:
sum_temperatures = 0Print a message telling a user to press the letterToQuit key numPresses times to quit. End with newline. Ex: If letterToQuit = 'q' and numPresses = 2, print:Press the q key 2 times to quit.Sample program:#include int main(void) { char letterToQuit = '?'; int numPresses = 0; return 0;}
Final answer:
To tell a user to press a certain key a number of times to quit in C, you can use the printf function to format and print the instructions, simply adjusting the variables for the key and number of presses.
Explanation:
The student is asking for assistance in writing a C programming code that prompts a user to press a specific key a certain number of times to perform an action, such as quitting a program. In this scenario, the student needs to complete the program by adding a statement to do this. Here's how you can write the code inside the main function:
#include <stdio.h>
int main(void) {
char letterToQuit = 'q';
int numPresses = 2;
printf("Press the %c key %d times to quit.\n", letterToQuit, numPresses);
return 0;
}
This code snippet sets the letterToQuit to 'q' and numPresses to 2, then it prints the message to the user. Adjust the variables letterToQuit and numPresses as necessary for different requirements.
___________ is Google’s machine-learning artificial intelligence system that interprets people’s searches to find pages that might not have the exact words they searched for.
Answer:
RankBrain
Explanation:
RankBrain is a machine learning-based search engine algorithm, the use of which was confirmed by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users.
Final answer:
RankBrain is Goog.le's AI system that helps interpret user searches for more effective results, considering factors like paid ads, popularity, and web connectivity. Search engine rankings are not based solely on content accuracy, so users should use approaches like SIFT to evaluate the credibility of information found online.
Explanation:
RankBrain is Goog.le’s machine-learning artificial intelligence system that interprets people’s searches to find pages that might not have the exact words they searched for. When using search engines like Goog.le, it's important to understand that results are not solely ranked based on authority, accuracy, or relevance. Instead, factors such as paid advertisements, popularity, and web interconnectivity can influence the visibility of web pages in search results.
As a result, it is possible for websites disseminating misinformation to manipulate search engine optimization (SEO) tools to boost their ranking in the search results. Therefore, users should exercise critical judgment and employ the SIFT method, which stands for the four moves of student fact-checkers, to assess the credibility of the sources they find online.

Explanation:
The people component of the five-component framework of an information system includes individuals who maintain the data and support the networks of computers. These individuals are often referred to as data stewards, professional data managers, and IT support staff.
They play a crucial role in ensuring that information systems function correctly by managing data storage, overseeing network security, helping in data integration, and providing support for both the hardware and software components of these systems.
Data stewards and professional data managers are essential in advising, assisting, and supporting all aspects of information management within organizations. They ensure data integrity and accessibility, which is a critical part of transforming data into valuable information.
This transformation is facilitated by information systems like database management systems, which people use to answer questions and make decisions based on analyzed data.
These IT professionals also work alongside hardware and software developers, who create the tools necessary for data management and information creation.
Together they ensure that commercial companies and academic institutions have complex and secure data storage systems that are both reliable and capable of handling the volume of data generated by today's technology-driven environment.
What is wrong with the following code fragment? int *p1, *p2; p1 = new int; p2 = new int; *p1 = 11; *p2 = 0; p2 = p1; cout << *p1 <<" " << *p2 << endl; delete p1; delete p2;
Answer:
Hi Hannahdavy! This is a good question. The problem lies in this part of the program:
p2 = p1;
Explanation:
In C/C++, memory is manually managed. When the variable p1 is assigned to variable p2, the memory allocated for p1 is left unmanaged, causing memory issues. Therefore the program will throw a “double free or corruption (fasttop)” error. What is needed to resolve the issue is to either (a) assign a null value to p1 after p1 has been assigned to p2, or (b) remove the p2 assignment of p1, depending of what the function is actually trying to do in the program.
