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.

car_makers['Tesla'] = "USA"

car_makers['Fiat'] = "Italy"

print("Acura made in",car_makers['Acura'])

print("Fiat made in",car_makers['Fiat'])

print("Tesla made in",car_makers['Tesla'])

Explanation:

The first line is a define object in the python code, containing two entries of Acura and Fiat and their respective countries.

The python code adds an entry to the object "car maker" using the bracket notation, the tesla car from USA.

The country of the Fiat car is changed from Germany to Italy, using the bracket notation.

How is an interpreter different from a compiler?

lyudmila [28]

Answer:

An interpreter is quite different from a complier due to the following statement below:

O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.

Explanation:

For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.

During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.

Hackers often argue that hacking is for the good of all people because it points out flaws in computer systems. do you agree wit

lutik1710 [3]

"Hackers" who work for companies to expose security flaws are definitely good, they're helping protect systems, often referred to as "white-hat" hackers. Many companies hire people like these or offer bounties for such people who can find vulnerabilities. One could say that even without permission, people who hack with the intent of demonstrating holes in security or improving a service could be considered good.

However, I don't believe that as firstly, they are breaking the law, and secondly, they are stealing data and invading people's privacy. One might as well break into somebody's house to say their security is bad!
