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.

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;
}
___________ 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.

The IMA or institute of management and accounting is one of the largest and most respected group or association of accountants and other financial professionals in the business industry, with the collaborative intent to advance and promote the management and accounting profession.
All members of the association obligatorily adhere to four principles. They are, honesty, fairness, objectivity and responsibility. And they also follow four IMA standards, which are credibility, competence, integrity and confidentiality.
The credibility standard includes disclosing all relevant information that could reasonably be expected to influence an intended user's understanding of the reports, analyses or recommendation.
The IMA standard requiring disclosure of all relevant information for understanding reports, analyses, or recommendations is grounded in the principle of transparency. This encompasses the clear presentation of data and an easily understandable format, adhering to the ISO 9000 Management Categories for quality and continuous improvement.
Explanation:The IMA standard that includes disclosing all relevant information that could reasonably be expected to influence an intended user’s understanding of the reports, analyses, or recommendations is transparency. Ensuring transparency involves the presentation of monitoring results and data in such a manner that stakeholders can fully comprehend the scope, methodology, biases, and limitations of the research. It is important to consider not only the content but also the format to make sure that the information is accessible and easily understandable.
According to the ISO 9000 Management Categories, part of this transparency involves clear communication and documentation that reveal what the organization planned to do, what it actually did, and the continuous improvement practices that are in place. This principle of transparency is vital to ensure that data, conclusions, and recommendations are fully understood by all stakeholders.

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.

An intranet is a network based on Web technologies that allows selected outsiders, such as business partners and customers, to access authorized resources of a company’s extranet.
(A) True
(B) False
Answer:
(A) True
Explanation:
Intranet is a network accessible only for the authorized users. For example, an organization intranet is accessible only for the organization members and same authorized non-members (business partners)
Intranet has a restricted network via special network protocols.
The statement is (B) False. An intranet is a private network that is not accessible by outsiders, while an extranet allows limited access to selected outsiders.
Explanation:The statement is (B) False.
An intranet is a private network that uses Internet technologies to provide access to authorized users within a specific organization. It is not accessible by outsiders such as business partners and customers.
Extranet is a separate network that allows selected outsiders to access certain resources of a company. It can be considered an extension of the company's intranet, but with limited access given to external parties.
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.
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.As you develop a Java program, you can use an IDE to Select one:
a. enter and edit the source code
b. compile the source code
c. run the application
d. all of the above
e. both B and C
Answer:
D) All of the above
Explanation:
An IDE refers to an Integrated Development Environment it is a software that allows a programmer to easily write and edit code, compile and run his/her application. One of the features of IDEs that makes a programmers job easier is syntax highlighting and automatic code completion.
popular Java IDEs that run on different operating systems platforms are are
Eclipes, Netbeans, IntellijIDEA, BlueJ, Jbuilder etc.
Answer:
(d) all of the above
Explanation:
An IDE (Integrated Development Environment) is basically a software application that allows programmers write and edit codes with so much ease.
IDEs have in them some special features that make code writing and software development an easy experience. Some of these features are;
i. Intellisense for automatic code completion and suggestion.
ii. build automation tools for building, compiling, running and even packaging application source codes.

1. Explain the distinction between interpretation and compilation. What are the comparative advantages and disadvantages of the two approaches?
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.
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.

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:
