Answer:
True
Explanation:
When changes are made in the source file, even if the destination file is closed, you can either do any of these two; you choose whether to update the link to display the current values when you open the destination file or continue to display the older values from the destination file till the destination file is opened.
Any of the two you choose will not affect the changes already made at the source file becsuse the source file controls the activities in the destination file.
Hence, the statement as ascertained to be true.

Create a do-while loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate
Sample Run1
Enter two numbers: 3 15
Do you want another operation: Yes
Enter two numbers: 45 56
Do you want another operation: No
Output1: Sum = 119
Sample Run2
Enter two numbers: 33 150
Do you want another operation: Yes
Enter two numbers: -56 56
Do you want another operation: Yes
Enter two numbers: 58 15
Do you want another operation: Yes
Enter two numbers: 123 87
Do you want another operation: No
Output2: Sum = 466
Answer:
import java.util.Scanner;
public class num3 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter two numbers: ");
int num1 = in.nextInt();
int num2 = in.nextInt();
int sum = num1+num2;
System.out.print("Do you want another operation: ");
String ans = in.next();
while(ans.equalsIgnoreCase("yes")){
System.out.print("Enter two numbers:");
num1= in.nextInt();
num2 = in.nextInt();
System.out.println("Do you want another operation: ");
ans = in.next();
sum = sum+(num1+num2);
}
System.out.println("sum = "+sum);
}
}
Explanation:
In the program written in Java Programming language,
The scanner class is used to prompt and receive two numbers from the user which are stored as num1 and num2. Another variable sum is created to hold the sum of this numbers
Then the user is prompted to answer yes or no using Java's equal.IgnoreCase() method.
If the user enters yes, he/she is allowed to entered two more numbers that are countinually added to sum
If the user eventually enters a string that is not equal to yes. The loop terminates and the accumulated value of sum is printed.

What machine learning technique helps in answering the question
Machine learning techniques like deep learning and reinforcement learning are pivotal for text analysis tasks, which require identifying and classifying patterns without explicit rules.
The question relates to machine learning (ML) to process textual data, where traditional rule-based systems fall short because of the complexity and variety of language. Such problems, like identifying references to a specific subject like the prophet Muḥammad in a corpus, require machine learning techniques to recognize patterns and infer rules that are not explicitly provided. ML techniques such as deep learning and reinforcement learning are especially potent in these scenarios, as they can learn from data to predict patterns and improve their performance over time, reducing bias and increasing the effectiveness of predictions.
Within the field of education, machine learning can help in the allocation of resources by analyzing data like satellite imagery combined with student enrollment information. This approach has been successfully used in international development efforts to predict poverty and mortality indicators, which demonstrates the potential utility of such techniques in helping answer complex questions and in making informed decisions.
You are a help desk technician providing support for a wireless network. A user calls and complains he cannot access the Internet. The user tells you he has good signal strength, but the network connection states "acquiring network address" and the IP address is all zeros. What could cause this problem?
Answer:
From the user explanations, it can be inferred that the issue may be as a result of incorrect security parameters such as Wireless Protected Access (WPA) which ensure security for wireless connections.
Explanation:
If there is an incorrect access pass to the wireless network by the WPA, any wireless user will not be able to complete a Layer 2 connection to the wireless network after connecting and getting good signal indication and would thus be unable to obtain IP address automatically to be able to log on to browse the internet from the DHCP Server.
Answer:
Incorrect connectivity configurations.
Explanation:
In many instances, the connectivity configurations may not be matching. This results in a loss in internet connectivity. Thus, the first thing will be to check the wireless area connections settings or simply the LAN settings. In addition, the local host or server can also check their systems to see if there are no generation problems on their side. Sometimes it may happen that external factors beyond the customer control can hinder the connectivity issues.
Mila received a new DVD player that she is trying to connect to the back of her television by feel alone. The first stage of memorizing how to make the connection would be through ____.
Answer:
The options for this question are the following:
a. iconic sensory memory
b. haptic sensory memory
c. short-term memory
d. long-term memory
The correct answer is b. haptic sensory memory.
Explanation:
Haptic memory has a capacity of 4 or 5 items, such as the iconic one, although the footprint is maintained for a longer time, about 8 seconds in this case. This type of sensory memory allows us to examine objects by touch and interact with them, for example to pick them up or move them properly.
It is believed that there are two subsystems that make up the haptic memory. On the one hand we find the cutaneous system, which detects the stimulation of the skin, and on the other the proprioceptive or kinesthetic, related to muscles, tendons and joints. It is appropriate to distinguish proprioception from interoception, which involves internal organs.
Haptic memory has been defined more recently than iconic and echoic, so that the scientific evidence available around this type of sensory memory is more limited than those that exist on the other two we have described.
Haptic memory depends on the somatosensory cortex, especially on regions located in the upper parietal lobe, which store tactile information. Likewise, the prefrontal cortex, fundamental for movement planning, also seems involved in this function.

Although online survey is the examination of anything such as web, tool, software or any popular app, etc, by which they can get that how many and how many peoples using or like those things.
So the following are the reason that the other options are not true according to the given statement.
Why would an administrator lower an RF signal on a wireless access point?
Increase QoS
Lower interference
Lower the signal to keep it in the building
Make it harder for guests to access the network
1. Increase QoS
Explanation:
The radio bands with lower frequency have relatively large wavelengths that are not as affected by objects such as building, trees, weather events or other features in the troposphere as the higher frequency radiation. General rule for radiation is that the lower the frequency, i.e. the longer the wavelength, the further a signal can penetrate through solid objects or liquids. Hence, when the frequency is lowered on a wireless access point, the signals can travel farther and smoother. Thus, increasing the quality of service.
When trying to remember a list of words, a person may choose a word to which they "hang" their memories on. This type of mnemonic device is called the _____ technique.
Answer:
Peg
Explanation:
This is known as the "peg technique." The name comes from the fact that we usually employ pegs to hang clothes to dry. In this memory aid, the person who wants to memorize something creates mental associations between two concrete objects. This is done in a one-to-one fashion that links all the words together.

The _____ is in effect when an interest group tries to mobilize large numbers of constituents to write, phone, or send e-mails and tweets to legislators or the president.
Answer:
Shotgun Approach
Explanation:
The shotgun approach is used in politics, marketing, and other areas as well.
In marketing, it is an approach to reach large populations or cover a wide area with product or service promotional campaigns.
In politics, however, it is considered more of a brute approach to handle certain issues. A large number of constituents are mobilized to reach the president or higher authorities (legislators) through different means, such as writing, phoning, sending emails or tweeting to emphasize their plight.
This approach is usually used when it is assumed that the legislator or president is not aware of what is going on with that location.

Some early computers protected the operating system by placing it in a memory partition that could not be modified by either the user job or the operating system itself. Describe two difficulties that you think could arise with such a scheme.
Here are two difficulties that I think could arise with a scheme that protects the operating system by placing it in a memory partition that could not be modified by either the user job or the operating system itself.
What's the issue about?The operating system would be difficult to update. Any changes to the operating system would require the entire operating system to be copied to a new memory partition. This could be a time-consuming and error-prone process.
The operating system would be vulnerable to hardware failures. If the memory partition containing the operating system were to fail, the entire operating system would be unavailable. This could cause a major disruption to the system.

Placing the operating system in a non-modifiable memory partition poses two main challenges: difficulty in applying software updates and complications in system recovery. Both of these issues stem from the inability to modify the protected partition.
Early computers sometimes placed the operating system in a non-modifiable memory partition to protect it from being altered by user jobs or the operating system itself. This approach has notable difficulties:
Software Updates: By placing the OS in a memory partition that cannot be modified, applying updates or patches to address vulnerabilities becomes extremely difficult. This can render the system vulnerable to new threats as patching bugs or upgrading the OS requires access to modify the partition, which is restricted.System Recovery: In the event of an OS malfunction or corruption, restoring the system becomes challenging since the OS partition cannot be modified or rewritten. This may require physical intervention to replace the memory hardware or specialized tools to bypass the protection, leading to longer downtimes and more complex recovery processes.These issues underline the balance modern operating systems must maintain between protecting their integrity and ensuring they remain flexible enough for updates and recovery.
You wish to use a file system that creates a record or log of to-be-committed changes in the system so that if the system crashes mid-change, it can recover gracefully. To do this, you will need to make use of a(n) ___________ file system.
Answer:
Journaling file system
Explanation:
A "file system" allows the control of data storage and retrieval.
The "Journaling file system" is a type of file system that records the to-be committed changes in the computer. This can track both of the data stored and the related metadata. This kind of data structure is then referred to as a "journal." So, this means that if the system crashes or a power failure happens, there is a lesser chance for the file system to be corrupted. It can also recover gracefully or even more quickly.
So, this explains the answer.
Final answer:
The correct answer is "journaling"To ensure data integrity and facilitate recovery from crashes, a journaling file system is required. It maintains a log of changes to be applied, allowing for graceful recovery. Additionally, version control is a related technology that manages file changes over time, useful for collaborative projects.
Explanation:
You wish to use a file system that logs changes before they're permanently committed to storage to ensure data integrity and provide a way to recover in case of a system crash. For this requirement, a journaling file system is the ideal solution. Journaling file systems such as EXT3, EXT4, and NTFS, keep a record of changes in a dedicated space known as a journal before they are applied to the main file system. In the event of a system failure during a write operation, the system can consult this journal to determine what changes were in progress at the time of the crash and apply them correctly, preventing data corruption.
Beyond journaling at the file system level, another related concept is version control, which is more specifically focused on managing changes to files over time, particularly for code and document collaboration. Popular version control systems include SVN (Subversion) and CVS (Concurrent Versions System). While a journaling file system protects against data loss from system crashes, version control systems provide a detailed record of edits, changes, and contributions over time, facilitating collaborative work and historical tracking of file changes.
Both journaling file systems and version control systems are essential tools in ensuring data integrity, recovery, and collaborative efficiency in computing environments.

Answer:
It would be an example of bottom-up planning
Explanation:
Bottom-Up Planning is a method of planning that defines objectives and ways to achieve them through the bottom up. It relatively narrows goals that are initially set at the lower levels of the organizational hierarchy. First, relatively close targets at lower levels of the organizational hierarchy are set. They are then gradually integrated into the framework of global goals and global strategy at higher and higher levels. It is therefore a convergent approach.
With bottom-up planning, you give your project deeper focus because you have a larger number of employees involved in the project, each with their own area of expertise. Team members work side-by-side and have input during each stage of the process. Plans are developed at the lowest levels and are then passed on to each next higher level. It then reaches senior management for approval.
