       }

       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.

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.

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.

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:

These issues underline the balance modern operating systems must maintain between protecting their integrity and ensuring they remain flexible enough for updates and recovery.

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.

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.

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.

Answer:

Moore's law

Explanation:

The Moore’s law which was named after the pioneer, Gordon Moore, predicted that the number of transistors on a chip would double about every two years. This law is one of the reasons why computers became so powerful. These transistors and chips are used to make mathematical calculations and in 1965, Gordon made an observation and forecasted that the number of transistors that can be placed in any ICs doubles approximately every two years. Moore was so convinced about this prediction that he went on to co-found the biggest chips processor; INTEL. This trend has been accurate since then but has started to slow down from 2013.

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.

So the following are the reason that the other options are not true according to the given statement.

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.
