Computer fundamentals hierarchy

What are the 4 levels of computing?
Level 1 − Micro architectural level.
Level 2 − Instruction set architecture.
Level 3 − Operating system.
Level 4 − Assembly language..
What are the advantages of computer memory hierarchy?
Overall, using a memory hierarchy in computer systems helps improve the system's overall performance and efficiency, making it faster, cost-effective, and efficient in its use of resources..
What is the justification for having a hierarchy of memories in a computer system?
The goal of Memory Hierarchy is to obtain the highest possible access speed while minimizing the total cost of the memory system.
Location of the Device (i) CPU registers-we call sometime internal memory. (ii) Cache memory-between CPU and Main memory or On chip Cache..
A hierarchy in programming is an organizational structure in which items are ranked according to levels of importance.
Most governments, corporations and organized religions are hierarchical.
In a computing context, there are various types of hierarchical systems.

Computer System Level Hierarchy consists of seven levels:

Level-0: It is related to digital logic.
Level-1: This level is related to control.
Level-2: This level consists of machines.
Level-3: System software is a part of this level.
Level-4: Assembly language is the next level of the computer system.
Level-5:
Level-6:

Performance. Without a memory hierarchy, there is a speed gap between CPU registers and the main memory. This increases access time and directly impacts the system's performance. Performance can be improved by reducing the number of levels required to access and manipulate data.

Hierarchy of classes of formal grammars

The Chomsky hierarchy in the fields of formal language theory, computer science, and linguistics, is a containment hierarchy of classes of formal grammars.
A formal grammar describes how to form strings from a language's vocabulary that are valid according to the language's syntax.
Linguist Noam Chomsky theorized that four different classes of formal grammars existed that could generate increasingly complex languages.
Each class can also completely generate the language of all inferior classes.
