How does an os using virtual memory ensure that pages containing the os kernel itself are never page out to make a frame available for a page?

Answers

Answer 1

Data structures and objects that can be safely paged out to storage are stored in virtual memory by NT kernels and device drivers. A driver, for instance, has the same ability as a user-mode program to request virtual memory.

Virtual memory's main function is to give users access to more RAM than the system's physical memory (RAM) allows for use by apps, programs, and other tasks. Virtual memory provides memory security by translating the memory address to the matching physical address, which is one of its key benefits.

However, the kernel contains data and code that must always be kept in memory for two reasons: 1) for efficiency reasons, and 2) because a page fault cannot be handled. Entering ISRs (interrupt service routines) is a common example (such as the page fault handling code itself). This kind of code and data are always retained in physical memory, and on NT kernels, they are referred to as a nonpaged pool.

The latter does not imply a direct connection to nonpaged memory addresses. The kernel memory management always converts them from virtual addresses to physical addresses (and vice versa).

What concept suggests that the best place to study for your psychology final to ensure good retrieval of concepts is your psychology classroom?.

Answers

The encoding specificity concept suggests that the best place to study for your psychology final to ensure good retrieval of concepts is your psychology classroom.

The main idea behind the encoding specificity principle is that retrieving episodic memories is aided by matching the encoding contexts of information to recall. It offers a paradigm for comprehending how environmental factors that are present during information encoding affect memory and recall of that knowledge.

Visual, auditory, and semantic encoding are the three main categories of memory encoding. An overarching theoretical foundation for comprehending how contextual information influences memory is provided by the encoding specificity principle of memory (Tulving & Thomson, 1973). The theory specifically asserts that information availability at encoding and retrieval improves memory.

According to the encoding specificity principle, how well a person performs on a memory test depends on how similar the practice and test situations are to one another.

Let me take a few examples:

What is your moral reaction to someone you see beating a dog mercilessly, especially if the quantum of violence is more than any irritation the dog could have caused.

How do you feel when you come across stories of people cutting of limbs of kidnapped children to make them beggars?How do you feel if a million people were to get killed in genocide as in the Rwanda genocide or in famine as in the Somalia famine?

I still am not a 100% sure    Hopes this helps  

Morality blends relativism and absolutism. Context shapes diverse cultural and personal beliefs, while universal principles like valuing human life persist, reflecting the complex nature of ethics.

The complex interplay between relativity and absolutism defines the nature of morality. Moral relativism highlights the diversity of moral perspectives across societies by acknowledging the influences of culture and the individual on ethical beliefs. On the other hand moral absolutism proposes universal values that cut across cultural boundaries such as the sanctity of human life.

A balanced viewpoint, however acknowledges that while some moral precepts are always valid others depend on the situation. The complex interaction of cultural norms, historical contexts and personal experiences shapes the development of the ethical framework. As a result morality incorporates aspects of both relativism and absolutism, reflecting the complex and dynamic nature of human values within the larger context of societal and individual perspectives.

How do you discover the mass of water removed?

Experimentally measuring the percentage water in a hydrate involves first heating a acknowledged mass of the hydrate to put off the waters of hydration and then measuring the mass of the anhydrate remaining. The distinction between the two loads is the mass of water lost.

Answers

A given processor with a 4-wide issue and 25 pipeline stages has a maximum of 100 instructions in flight.

The throughput of a CPU is increased through pipelining. The clock speed of the chip can be increased by adding pipeline stages because each step can operate more quickly. The number of instructions that may be performed at once grows with the number of pipeline stages.

However, the additional pipeline registers will result in an increase in the latency of individual instructions. Additionally, the cost of space and electricity for the pipeline registers has increased. The fact that expanding pipeline stages only works if you have instructions to feed the pipeline is a major problem. Additionally, branch mispredictions can be particularly expensive because a longer pipeline can result in more computation being "wasted" on a branch misprediction. As a result of the error, the obtained throughput is likewise less than the maximum achievable.
