Why is a memory hierarchy of different memory types used instead of only one kind of memory?

1 answer:

5 0

Answer: Memory hierarchy is the hierarchy that is created on the basis of the response time of different memories. The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.

Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.

Thus hierarchy of any particular system is in the form of fast to slow order from registers,cache memory, Random access memory(RAM) and secondary memory.

vlabodo [156]

Answer:

short_names = ["Gus", "Bob", "Ann"]

print(short_names[0])

print(short_names[1])

print(short_names[2])

Explanation:

There are some typos in your code. In addition to the missing part of the code, I corrected the typos.

First of all, initialize the list called short_names. The list starts with "[" and ends with "]". Between those, there are must be the names (Since each name is a string, they must be written between "" and there must be a semicolon between each name)

Then, you can print each name by writing the name of the list and the index of the names between brackets (Index implies the position of the element and it starts with 0)

Compared to using a command line, an advantage to using an operating system that employs a gui is ________.

artcher [175]

Compared to using a command line, an benefit to using an operating system that employs a GUI exists you do not have to memorize complicated commands.

<h3>What is operating system?</h3>

An operating system (OS) exists as the program that, after being initially loaded into the computer by a boot program, contains all of the other application programs on a computer. The application programs create use of the operating system by completing requests for services through a specified application program interface (API).

A GUI utilizes windows, icons, and menus to carry out commands, such as opening, deleting, and moving files. Although a GUI operating system is especially navigated using a mouse, a keyboard can also be utilized via keyboard shortcuts or arrow keys.

The GUI, a graphical user interface, exists as a form of user interface that permits users to interact with electronic devices via graphical icons and audio indicators such as primary notation, instead of text-based UIs, typed command labels, or text navigation.

Hence, Compared to using a command line, an benefit to using an operating system that employs a GUI exists you do not have to memorize complicated commands.

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?

Ganezh [65]

Answer:

The correct answer to the following question will be "Adaptive Optics".

Explanation:

AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.

It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.

Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.

Therefore, Adaptive Optics is the right answer.

What is the reason of non-deterministic (indeterminate) behavior of concurrent programs?

murzikaleks [220]

Answer: Concurrent programs are the programs that execute at the same point of time. They are simultaneous in nature with other concurrent programs.They are executed with the help of threads to achieve the concurrency without the issue of scheduling. They are consider long running programs.

The program that has the low execution time compared with all other programs gets executed first.If the case of no progress is seen then another thread is executed.This type of execution gives the non- deterministic situation in which the possibility of leading completion of any particular program cannot be determined.

OLEGan [10]

Answer:

Explanation:

The /var subdirectory contains files to which the system writes data during the course of its operation. Hence, since it serves as a system directory, it would prevent log files from consuming a large amount of data.
