What is the nx bit and which form of the buffer overflow attack does it protect against?

Answers

Answer 1
NX bit marks parts of memory as "no execute", so that even if it contains executable code, the CPU will not execute it. Some buffer overflow exploits place executable code in a buffer (and beyond), then attempt to redirect execution to this area to gain control over a process. 

In windows this is called Data Execution Prevention.

When you save data on a disk, the OS places it in an available storage area, or a "Sector".
Usually the computer places that data in sectors in an order and usually next to each other but that is not the case always, sometimes part/s of that data can be scattered at different places which actually slows down the computer, for which we need to Defragment the disk space.   

What software emulates the hardware on which an operating system runs?

Answers

Virtualization software is what emulates the hardware on which an OS runs.
Hope this helps :D

A hypervisor or virtual machine monitor (VMM) is software that emulates the hardware for an operating system, facilitating server virtualization by allowing multiple OS to run on the same physical hardware.

The software that emulates the hardware on which an operating system runs is known as a virtual machine monitor (VMM) or hypervisor. A hypervisor creates a virtual version of a computer system that allows multiple operating systems to share the same physical hardware resources.

This technology is essential for server virtualization, helping to reduce the need for excess physical servers and allowing for efficient resource management. There are two main types of virtualization: hardware virtualization and software virtualization. Hardware virtualization is typically more efficient as it directly manages the hardware resources without the need of a host operating system.

In contrast, software virtualization runs on top of an existing operating system, utilizing more system resources but offering simpler management.

Answers

It should be A face, I think

Answer:

A. Face

Explanation:

A poppet valve some time called mash room valve.The word poppet shares etymology with "puppet". In past "puppet valve" was synonym for poppet valve. however, this usage of "puppet" is now obsolete. The valve stem moves up and down inside the passage called guide, which is fitted in the engine-block. the head of the valve called valve face, is generally ground to a 45 degree angle. So as to fit properly on the valve seat in the block and prevent leakage.

Image files are grouped into two categories: _____.

Answers

Final answer:

Image files can be broadly classified into two categories: raster graphics and vector graphics. Raster graphics are pixel-based and include formats like JPEG, GIF, and BMP, whereas vector graphics use mathematical formulas to represent images, allowing them to be scaled without losing quality, with SVG being a common format.

Explanation:

Image files are grouped into two categories: raster graphics and vector graphics. Raster graphics, such as JPEG, GIF, and BMP, store images as a collection of pixels, with each pixel representing a single color. The quality of these images is dependent on their resolution, with higher pixel densities resulting in sharper images. Examples of raster graphics include digital photos which are often seen in JPEG format. On the other hand, vector graphics, such as SVG, define images using mathematical formulas that represent shapes and lines. This allows vector images to be scaled up or down in size without losing quality, making them ideal for logos and other designs that need to be resized frequently. Common examples of vector file formats include SVG (Scalable Vector Graphics).

Understanding the differences between these two categories is essential for working efficiently with digital images, each having their unique advantages depending on the application.

Variables that are shared by every instantiation of a class are ___________.

Answers

static variables, sometimes also called class variables, as opposed to instance variables, that only live in one instantiation (object) of a class.

Variables that are shared by every instantiation of a class are class variables. Class variables are those that contain static modifiers in their declaration.

What are class variables?

They are also known as static variables. In the definitions of functions, a class or variable parameter serves as a model for a family of classes or variables. It is an important part of object-oriented programming (OOP).

When used as an input, such as when passing a value to a function, and when used as an output, such as when obtaining a value from the same function. They can, for example, serve as a model for a function.

Therefore, the Class variables are those that are shared by all instances of a class. Static modifiers appear in the declaration of class variables.

If a magnetic disc has 100 cylinders, each containing 10 tracks of 10 sectors and each sector can contain 128 bytes, what is the maximum capacity of the disk in bytes

Answers

Answer:

The maximum capacity of disc is 12,80,000 bytes.

Step-by-step explaination:

Given a magnetic disc having 100 cylinders & each containing 10 tracks of 10 sectors. Hence, total no. of sectors in magnetic disc are [tex]100\times 10\times 10[/tex]=10000 sectors

Each sector contain 128 bytes.

we have to find the maximum capacity which can be calculated as

Maximum capacity = No. of sectors[tex]\times[/tex]capacity of sectors

                               =  10000[tex]\times[/tex]128

                              = 12,80,000 bytes

The maximum capacity of the disk is 1280000 bytes.

Further Explanation:

It is given that a magnetic disc having 100 cylinders and each cylinder containing 10 tracks of 10 sectors.

Therefore, the number of sectors in the magnetic disc is the product of total cylinders, tracks and sectors.

The number of sectors is calculated as,

[tex]\begin{aligned}\text{Total sectors}&=100\times 10\times 10\\&=10000\end{aligned}[/tex]

The maximum capacity of the magnetic disc is the product of number of sectors in magnetic disc and capacity of a sector.

[tex]\begin{aligned}\text{maximum capacity}&=10000\times 128\\&=1280000\end{aligned}[/tex]

Thus, the maximum capacity of the magnetic disc with 10000 sectors and capacity of 128 bytes is 1280000 bytes.

How can you reduce the size of the blind spots

Answers

The physiological blind spot refers to a zone of functional blindness all normally sighted people have in each eye, due to an absence of photoreceptors where the optic nerve passes through the surface of the retina. Here we report that the functional size of the physiological blind spot can be shrunk through training to distinguish direction signals at the blind spot periphery. Training on twenty successive weekdays improved sensitivity to both direction and color, suggesting a generalizable benefit. Training on one blind spot, however, did not transfer to the blind spot in the untrained eye, ruling out mediation via a generic practice effect; nor could training benefits be attributed to eye movements, which were monitored to ensure stable fixation. These data suggest that training enhances the response gains of neurons with receptive fields that partially overlap, or about, the physiological blind spot, thereby enhancing sensitivity to weak signals originating primarily from within the functionally-defined region of blindness. Our results have important implications for situations where localized blindness has been acquired through damage to components of the visual system, and support proposals that these situations might be improved through perceptual training.

Emilio has created a document in Word and needs to print labels. He is shopping at a store and finds Avery labels and another brand that is less expensive. What does Emilio need to do before buying the less expensive labels?

Answers

He needs to make sure that the less expensive label is compatible with Word. 
Final answer:

Emilio should check the less expensive labels for Word compatibility, ensure they fit his printing and application needs, and confirm that he can create or find a suitable template before purchasing.

Explanation:

Before Emilio purchases the less expensive labels, he needs to ensure that they are compatible with the Word document he created for printing labels. First, he should check the packaging of the labels to see if they provide a template or mention compatibility with Word. Many label manufacturers offer templates that can be downloaded and used within Word. If no information is provided, Emilio should look for the label size and compare it to the available templates in Word, or consider measuring the label dimensions and configuring a custom template if necessary.

Furthermore, Emilio should make sure that his printer can handle the label material and that the label adhesive is suitable for the surface to which they will be applied. If the less expensive labels provide all the necessary details for creating a Word template and are suitable for his printing and application needs, he can opt for the more affordable option without compromising his project.

Why do computers use binary instead of decimal?

Answers

In binary numbers, instead of each number place is multiplied by ten, they are multiplied by two. This allows long strings of number to still be translated into standard numbers and letters. Eight binary number strings are the most useful and most used set of binary numbers. The eight-number sets allow the computer to process numbers from zero to 255. These eight numbers are also the smallest binary sets that give the right amount of number options to represent letters. This is similar to how the binary numbers are used to represent pictures. Pictures are made up of pixels, which are digital representations of the picture. The pixels coincide with binary codes, which tell the computer how much red, blue or green is needed to create the color on the screen. Each pixel is normally represented by up to three bytes or three of the eight digit binary codes.
Final answer:

Computers use binary because it corresponds to the two possible states of electronic components: on and off, making data processing straightforward and reliable. Binary systems provide simpler storage, vast representational scope, and security benefits particularly evident in encryption key possibilities. The digital nature of binary is echoed in biological systems and the evolution of quantum computing.

Explanation:Why Do Computers Use Binary Instead of Decimal?

Computers use binary instead of decimal because they rely on the electronic states which represent two possible states: on and off. Binary is a system that is represented with two unique digits (0 and 1), corresponding to these off and on states respectively. This simplicity allows computers to perform operations reliably and efficiently. Processing binary data is also more straightforward due to the nature of digital circuits, which handle two distinct states more easily than multiple states required by a decimal system. For instance, in ASCII encoding, the letter A is represented as the number 65, which in binary is 1,000,001.

Additionally, binary allows for simpler and more reliable storage and processing of data. Binary representation of numbers, like the decimal number 1837 being 11100101101 in binary, is managed internally by using sequences of binary digits to encode information. Computers can represent very large numbers, such as with AES-128 and AES-256 encryption keys, where the number of possible keys is 2128 and 2256 respectively. This demonstrates not only the vast representational scope but also the security that binary encoding can provide due to the computational difficulty of attempting every possible key combination.

The binary system is fundamentally suited to digital technologies and replicates the digital nature of biological systems, such as DNA encoding with A, C, G, and T. It also contributes to clearer data transmission for cell phone conversations and television signals. Moreover, the advent of quantum computing further emphasizes the benefits of binary systems, as qubits which behave based on quantum mechanical phenomena still rely on digital manipulation of data.

After a few days of retirement following World War II, Marshall was called upon by the President to help manage the crucial problems of waging peace. As Secretary of State from 1947 to 1949, he was the personal architect of the American diplomatic and economic program which turned the tide of Communism in war-ravaged Western Europe. This program came everywhere to be known as the "Marshall Plan" and led to the coalition of free nations under the North Atlantic Treaty Organization (NATO), paving the way for a revitalized Europe.
