Answer:
B, False.
Explanation:
Remote access is the ability of a device in a network to achieve a remote connection and control of another system. Its connection is not physical but uses telecommunication or the internet to access systems that cannot be accessed physically.
The RDP or remote desktop protocol is an example of protocols used to remotely access other computers in a network. It connects to the graphical interface of the other computer. When private data is compromised in a remote access, automatic blocking cannot be used to cancel an already established connection, but the system should be shutdown to prevent further exposure.

This is an infinite loop. D. The loop will not be executed, the initial value of x > 5.
Answer:
Option B is the correct answer.
Explanation:
In the above code, the loop will execute only one time because the loop condition is false and it is the Do-While loop and the property of the Do-while loop is to execute on a single time if the loop condition is false.Then the statement "x*=20;" will execute one and gives the result 200 for x variable because this statement means "x=x*20".SO the 200 is the answer for the X variable which is described above and it is stated from option B. Hence it is the correct option while the other is not because--Option A states that the value is 10 but the value is 200.Option C states that this is an infinite loop but the loop is executed one time.Option D states that the loop will not be executed but the loop is executed one timeComputer processing work that is split between a desktop computer and a more powerful computer that processes and stores shared data, serves up web pages, or manages network activities is called ________ .
Answer:
Client-server is the correct answer for the above question.
Explanation:
Client-server is a model in which the server gives services and the client takes services. This model comes in the concept of the internet which is the connection of multiple computers to share the information. The client stands for the host computer which is connected to the network and takes the service from the server.The server is called that computer which gives services to many host computers.This model splits the work between a powerful computer (server) and a desktop computer (clients). The powerful computers process the data, store the data and give services to desktop computers.The above question-statement asked about that model which is the powerful computer and give services and the other is to take the services then the answer is the client-server model. Hence the answer is the client-server model.The idea that innovations in transportation and communication technologies has changed the way we think about distance and time is the central argument of __________________________ theory.
Answer:
Innovations in transportation and communication technologies has actually changed the way we think about distance and time
Explanation:
Transportation and communication were part of the major challenges humanity was facing in time past, the distance between places was seen as a barrier, it delayed many things, communication inclusive because of the lengthy time involved in sending messages, goods and services from one place to another, this gave birth to invention of various means of getting these major activities (that man can not do without) done without wasting much time. Ever since then man has began to see distance and time from a completely different angle, things that will take months to get done because of the great distance in time past can actually be carried out today in a couple of seconds.
Write multiple if statements. If car_year is 1969 or earlier, print "Few safety features." If 1970 or later, print "Probably has seat belts." If 1990 or later, print "Probably has antilock brakes." If 2000 or later, print "Probably has airbags." End each phrase with a period and a newline. Sample output for input: 1995 Probably has seat belts. Probably has antilock brakes.
Answer:
import java.util.Scanner;
public class Hggg {
public static void main (String [] args) {
System.out.println("Enter the car make year");
Scanner in = new Scanner(System.in);
int car_year = in.nextInt();
if (car_year<1969){
System.out.println("Few safety features.");
}
else if (car_year>=1970 && car_year<1990){
System.out.println("Probably has seat belts.");
}
else if (car_year>=1990 && car_year<2000){
System.out.println("Probably has seat belts.");
System.out.println("Probably has antilock brakes.");
}
else if (car_year>=2000){
System.out.println("Probably has seat belts.");
System.out.println("Probably has antilock brakes.");
System.out.println("Probably has airbags.");
}
}
}
Explanation:
In this solution, multiple if statements have been used to accomplish each step. Observe that there are more than one print statements when year is greater than 1990 because the condition applied to year greater than 1970 holds true for every year greater than 1970 (1990, 2000 etc)
An archive of files that usually contain scripts that install the software contents to the correct location on the system is referred to as a:1) package manager
2) DBMS
3) tarball
4) router
Answer:
Option 3 is the correct answer for the above question.
Explanation:
A tarball is a software which is used to encrypt the other software or hide the other software and make it small. It again makes the original software program from the encrypted ones.It is used to make the file sort and can use for the transfer which takes some amount of memory.The above question asked about that technology which is used to make encrypted software from the original software and use it with the help of some script. Then the answer is tarball which is referred to from option 3. Hence Option 3 is the correct answer for the above question while the other is not because--Option 1 states about the package manager which is used to manage the library only.Option 2 states about the DBMS which is used to manage the database.Option 4 states about the router which is used for the internet.
The correct option is (3) tarball. An archive of files that usually contain scripts that install the software contents to the correct location on the system is referred to as a tarball.
A tarball is a term used in computing to describe a collection of files that have been packaged together using the tar command on Unix-based systems. The files are combined into a single archive file, typically compressed to save space. This often includes installation scripts or compiled code that can be easily transported and deployed. This differs from a package manager, which is a tool that automates the process of installing, upgrading, configuring, and removing software packages for a computer's operating system in a consistent manner. A DBMS (Database Management System) is software for creating and managing databases. A router is a network device that routes data from one network to another.
This loop is a good choice when you know how many times you want the loop to iterate in advance of entering the loop.1. do-while2. while3. for4. infinite5. None of these
Answer:
Option 3 is the correct answer.
Explanation:
In c, c++ or Java programming language, The for loop takes three parameters in which first is an initialization, second is condition check and the third is an increment. None of the other loop (except for loop) takes three parameters. The other loop takes only one parameter and that is the condition check.So when a user knows about the times of iteration then it is a good choice to use the for loop but when the person does not know about the times of iteration if the loop. It means the iteration of the loop is based on the condition then it is a good choice to chose while or Do-while loop.The above question wants to ask which loop for a user can best if he familiar with the iteration of the loop then the answer is for loop which is started from option 3. Hence Option 3 is the correct answer while the other is not because--Option 1 states about the do-while loop which takes condition only.Option 2 states about the while loop which also takes condition only.Option 4 states about the infinite loop which is not any loop.Option 5 states about none of these which is not correct because option 3 is the correct answer.A for-loop is the ideal choice when the number of iterations is known before entering the loop because it allows you to set the exact number of iterations in advance.
Explanation:The loop that is a good choice when you know how many times you want the loop to iterate in advance of entering the loop is the for-loop. For-loops are structured to repeat a block of code a specific number of times, and this is established by setting the conditions of the loop before it starts running. In contrast, while-loops execute based on the truthfulness of a condition and are better suited when the number of iterations is not known beforehand. Do-while loops are similar to while-loops but will always execute at least once, even if the condition is false from the start. An infinite loop is a loop that does not have a condition that evaluates to false, thereby running indefinitely, which is usually not desired. For-loops in most programming languages are defined using the keywords for ... in and an iterator variable.
Astrid's computer screen suddenly says that all files are now locked until money is transferred to a specific account, at which time she will receive a means to unlock the files. What type of malware has infected her computer?
Answer:
Ransomware
Explanation:
Ransomware is a special case of malware. It is a malicious program that infects a computer system by locking its screen and encrypting all its files and data and a certain amount of money (ransom) is requested from the owner of the system. Until the money is paid the screen remain locked and the files and data remain encrypted.
It is a very dangerous malware targeted towards organizations and even individuals. So systems that don't have strong security around them are easily attacked by this ransomware.
Note: A special type of ransomware is crypto malware or cryptojacking.
Which of the following attacks seeks to introduce erroneous or malicious entries into a server's hostname-to-IP address cache or zone file?
Answer:
DNS poisoning or DNS cache poisoning
Explanation:
It is also called spoofing. It is a type of cyber attack in which the Domain Name System server data is modified. This modified and corrupted data is entered in DNS cache as a result of this, the internet traffic is redirected to some fake and fraud servers. These fake servers is controlled by the attacker. DNS basically coverts the domain names to IP addresses. Domain name (such as iamthebest.com) is understandable by humans so DNS translates it to IP address which is readable by computer. So when the computer gets a domain name, as domain name is readable by humans, so a computer will reach a DNS server to request the translation. The DNS server responds to this request by providing the IP address where the computer can locate that domain name. So the DNS server has a cache which stores the frequently requested translations so that it does not have to look up to other servers every time for the same request. If an incorrect translation has been entered into the DNS cache, it is said to be poisoned. Lets say some attacker modifies or corrupts some data in the DNS server as a result of which the web server directs the user to the wrong IP address of the attacker which might contain a malicious website. As the Internet Service Provider caches data from other DNS servers so the DNS poisoning can spread as the affected DNS server's information can be cached to other ISPs as they keep on storing false translations.As a result of DNS poisoning the users are diverted from the target website to a website that belongs to an attacker and contain viruses or a phishing website which can take personal information from the user such as credit card information.The details of _____ vary from state to state, but generally create personal jurisdiction over nonresidents who transact business or commit tortious acts in the state.

Lucy wants to develop a web page to display her profile. She wants to just start with a basic page that lists her accomplishments, her work history, and the different computer courses she has taken. She would like each section to be clearly identified.Which type of list would work best for listing Lucy's accomplishments?1. unordered list2. header list3. legends list4. definition list
Answer:
1. Unordered list.
Explanation:
Web development is the creation of web pages. A web page can be a portfolio or personal website, an e-store etc. The web page comprises of a header, body and a footer component.
The header is the introduction of the web page, it holds the brand name, logo and other introductory elements.
The body is the main content of the web page. It uses other elements like the list to hold a group of data. There two types of list, they are ordered and unordered list. The ordered list are numbered while the unordered list are dotted not numbered.
Lucy would use the unordered list to outline are accomplishments and certification in details.
Final answer:
The best type of list for listing Lucy's accomplishments on a web page is an unordered list, as it presents each item with equal importance and enhances readability. Proper introduction and conclusion around the unordered list further improve the content's clarity and accessibility. The correct answer is option (1)
Explanation:
For displaying Lucy's accomplishments on a web page, an unordered list would be the most appropriate choice. An unordered list ensures that each accomplishment is given equal importance, avoiding any implication of ranking or sequence that a numbered list might suggest. Furthermore, unordered lists are commonly used for listing items like hobbies, interests, and personal achievements on web pages, making them familiar and easily readable by visitors.
When using an unordered list to showcase accomplishments, it is good practice to introduce the list with a brief explanation of its contents. This practice aids the reader in understanding the context of the list. After detailing the list of accomplishments, it is also helpful to provide a follow-up comment or summary to conclude the section effectively.

which of the following is the term used for a set of programs that acts as an interface between the applications that are running on a computer and the computer's hardware?
Answer:
Operating System
Explanation:
Operating System is a software program which acts as an mediator between computer hardware and user program applications and allows interaction between the user and computer/hardware. OS is used to manage both the hardware and software related tasks. OS is used to manage memory. It allocates memory to various processes and manages the primary memory by monitoring what portion of it is in use and what portion is not in usage.OS is used to manage processes by allocating and deallocating resources to processes which is also called process scheduling.It also provide security by preventing unauthorized access to data and computer. This is done via passwords which identify who is authorized to use a computer programs or manipulate data.Operating system also communicates with hardware devices via device drivers and also monitors the devices through I/O controller.OS allows communication between user and computer. User cannot understand computer language therefore assemblers, compilers, interpreters are provided by the OS to the user to interact with computer and computer programs.OS also controls and manages file system, it checks the status of the files, manages the directories and files and keeps information about where the data is stored.If you are signed into a Microsoft account and need to sign into another one, click ____ on the list arrow next to Your Name in the top-right corner of the Word window.
Answer:
left
Explanation:
If you are signed into a Microsoft account and need to sign into another one, click left on the list arrow next to Your Name in the top-right corner of the Word window.
Multiple Microsoft accounts can be opened at one time in different tabs of your computer. They can be used simultaneously as well. It helps the user to work efficiently rather than logging in or logging out from his accounts which hinders effective and efficient output.
To switch to another Microsoft account in Word, click 'Sign out' or 'Switch accounts' next to your name in the top-right corner. Account management options are usually found under the File tab. The exact wording may differ slightly depending on your version of Office.
If you are signed into a Microsoft account and need to sign into another one, click 'Sign out' or possibly 'Switch accounts' on the list arrow next to Your Name in the top-right corner of the Word window. The procedure for switching accounts may vary slightly depending on the version of Microsoft Office you're using, but generally, there should be an option to manage your account or switch accounts when you click on your name or user icon. For example, in some versions, after you click on your name, you might see an option to sign out, which you must do before signing in with a different account. Or, there might be a 'Switch accounts' option directly in the menu, allowing you to exchange one account for another without signing out first.
In Microsoft Office programs, such as Word or Excel, account management options can typically be found by clicking on the File tab which leads you to the Account or Office Account section. Here you can add services or sign in with different credentials depending on your needs.
A BufferedReader has a constructor that takes a single InputStreamReader parameter. InputStreamReader has a constructor that takes a single InputStream parameter. Suppose there is a class Widget InputStream that is a subclass of InputStream and suppose there is a variable, wis, that refers to a Widget InputStream object. Write an expression whose value is a reference to a newly created BufferedReader that is based on the WidgetInputStream object wis refers to.
Final answer:
To create a BufferedReader based on a WidgetInputStream object, you would use the expression 'new BufferedReader(new InputStreamReader(wis))', which chains the streams together.
Explanation:
The question asks how to create a BufferedReader that is based on an existing WidgetInputStream object. The WidgetInputStream is a subclass of InputStream, meaning it can be passed to the constructor of an InputStreamReader, which in turn can be used to create a new BufferedReader.
The expression to create the BufferedReader based on the WidgetInputStream object referred to by wis is:
new BufferedReader(new InputStreamReader(wis))
This will wrap the WidgetInputStream in an InputStreamReader, and then wrap that in a BufferedReader, effectively chaining these streams for efficient reading of characters, arrays, and lines.
Something is wrong with the logic in the program above. For which values of time will the greeting "Good Morning!" be displayed? var time = promptNum("What hour is it (on a 24 hour clock)?"); var greeting = ""; if (time < 6) { greeting = "It is too early!"; } else if (time < 20) { greeting = "Good Day!"; } else if (time < 10) { greeting = "Good Morning!"; } else { greeting = "Good Evening!"; } console.log(greeting);
Answer:
There is logic problem in condition of elseif statement that is (time<20).
Explanation:
elseif(time<20) will be true for time<10 that means program will never greet good morning as to make logic correct either change condition from elseif(time<20) to elseif(time<20&& time>=10). Or change the order of condition like check first for elseif(time<10)
solution 1
if (time < 6) { greeting = "It is too early!"; }
else if (time < 20 && time>=10) { greeting = "Good Day!"; }
else if (time < 10) { greeting = "Good Morning!"; }
else { greeting = "Good Evening!"; }
console.log(greeting);
solution 2
if (time < 6) { greeting = "It is too early!"; }
else if (time < 10) { greeting = "Good Morning!"; }
else if (time < 20 ) { greeting = "Good Day!"; }
else { greeting = "Good Evening!"; }
console.log(greeting);

Explain the significance of the loss of direct, hands-on access to business data that end users experienced with the advent of computerized data repositories.
Final answer:
The shift to computerized data repositories reduced direct access to business data, leading to efficiency gains but also risks such as system failures and data breaches. Dependence on technology has widened the digital divide and had societal impacts such as job loss.
Explanation:
The emergence of computerized data repositories marked a significant shift in the way end users interacted with business data. With computerization, direct, hands-on access to data decreased, which led to a reliance on digital systems to process and interpret information. This transformation has had profound impacts on businesses and employees. In the era before widespread computer use, businesses used tools like the Farmer's Almanac and Weather Bureau data; by contrast, today's business decisions are informed by data from global positioning systems, historical rainfall patterns, and other complex services.
The move away from direct data interaction meant that businesses became more efficient at data analysis and decision-making but also became dependent on technology. This dependence carries risks like system failures, data breaches, and the loss of personal data privacy. Furthermore, the digital divide has widened as technology becomes more central to operations. The societal and economic changes accompanying technological shifts, such as automations in manufacturing and mining, have profound repercussions, including job losses and the restructuring of whole communities.
Final answer:
The loss of direct, hands-on access to business data that end users experienced with the advent of computerized data repositories has both advantages and disadvantages. While physical access allows for manual verification and manipulation of data, computerized data repositories provide efficient storage, organization, and accessibility of data.
Explanation:
The significance of the loss of direct, hands-on access to business data that end users experienced with the advent of computerized data repositories is that it has both advantages and disadvantages. While computerized data repositories provide efficient storage, organization, and accessibility of data, end users lost the ability to physically interact with the data. This loss of physical access can affect the ability to manually verify and manipulate information, potentially leading to errors or limitations in data analysis.
For example, in the past, end users might have been able to physically hold and review paper documents, allowing them to manually check for any discrepancies or inconsistencies. With computerized data repositories, end users typically only have digital access to the data, which limits their ability to perform hands-on verification.
However, the advantages of computerized data repositories often outweigh the disadvantages. These repositories provide fast and efficient access to vast amounts of data, enabling end users to analyze and make informed decisions more quickly. They also offer features like searchability, data security, and data backups that can enhance data management and protection.
The information gathering technique that enables the analyst to collect facts and opinions from a wide range of geographically dispersed people quickly and with the least expense is the___________.
a. document analysis
b. interview
c. JAD session
d. observation
e. questionnaire
Answer:
E. Questionnaire.
Explanation:
Information gathering is a technique or mechanism for collecting a large data for data analysis.
Questionnaires are paper documents with a well-thought list of questions meant for a large group of people to answer individually. They are faster and cheaper to implement.
Document analysis requires for an acquired document to be assessed or graded for analysis. Interviews are established between the information seeker and individuals directly. Observation is a long process of monitoring a sampled group for data collection. The JAD is a more complicated and effective way of data collection, it requires collection of data from different perspectives and locations. It is time consuming and expensive.

Which of the following is the MOST sensitive Personally Identifiable Information (PII) and should be shared cautiously and only with trusted resources?A. Email addressB. Phone numberC. Mother’s maiden nameD. Last name
Final answer:
The most sensitive PII among the given options is the mother’s maiden name, as it's commonly used in security questions and identity verification.
Explanation:
The most sensitive Personally Identifiable Information (PII) that should be shared cautiously and only with trusted resources among the options provided is C. Mother’s maiden name. This piece of information is often used as a security question for various accounts and can be used for identity verification. Consequently, it can provide access to someone’s personal and financial details if it falls into the wrong hands. While an email address, phone number, and last name are unique to individuals and are considered PII, the mother’s maiden name holds a higher risk and sensitivity due to its common use in security settings.
