What are the fundamental concepts that underlie operating systems?

You will develop an OS Theory Concept Map to answer this focus
question: What are the fundamental concepts that underlie operating
systems? You will more specifically address the following topics
represented in the Course Learning Outcomes (CLO):
Features and structure of contemporary operating systems
Threads and process synchronization
Memory management
File systems
Mass storage
I/O
Security and protection
Assignment Prompt:
You will use your concept map to resolve this focus question: What
are the fundamental concepts that underlie operating systems? Throughout
the course, each week will include an assignment to build upon your
existing concept map, adding nodes to represent the topics that were
covered that week. You will link the related concepts to represent and
explain their relationships.
To begin your concept map, you will
Label the central node to rename it and start building your concept map from it.
Logically arrange the essential concepts about operating systems
theory into a hierarchy of nodes that branch from the main idea. Include
cross-links where necessary to show relationships in different sections
of the concept map.
Use connecting nodes to accurately describe each relationship
between topics that connect. Every neighboring pair of concepts should
be linked by a word or phrase to form a short sentence. For example, to
represent the idea that “Topic A causes Topic B, Topic C, and Topic D,”
you will use a connecting node for the word “causes” in between Topic A
and Topics B, C, and D, as shown in this screenshot.
Section 1:
You initially completed this section in your Week 1 interactive
assignment. Review the instructions here and incorporate your peer and
instructor feedback from the Week 1 interactive assignment in your final
version of the concept map.
In this section, you will begin your concept map by addressing each
of the following topics concerning operating system features and
structures:
Categorize, describe, and give examples of the major functions of operating systems.
Illustrate the hierarchy of subsystems, components, or subcomponents
of operating systems and explain how they interact with one another.
Section 1 about features and structures must have at least two nodes and at least seven connecting nodes.
Section 2:
You initially completed this section in your Week 2 interactive
assignment. Review the instructions here and incorporate your peer and
instructor feedback from the Week 2 interactive assignment in your final
version of the concept map.
In this section, continue building the concept map by addressing the
following topics concerning how operating systems enable processes to
share and exchange information:
Describe process, process state, and process control block.
Compare single- and multi-threaded motivations and models.
Describe the critical-section problem and explain a software solution that resolves this problem.
Section 2 about processes must have at least three nodes and four connecting nodes.
Section 3:
You initially completed this section in your Week 3 interactive
assignment. Review the instructions here and incorporate your peer and
instructor feedback from the Week 3 interactive assignment in your final
version of the concept map.
In this section, continue building the concept map by addressing the
following topics concerning controlling and coordinating computer
memory:
Outline the objectives and functions of memory management in
operating systems. (Resource: Leverage Figures 7.1, 7.2, 7.3, and 7.4
from the textbook.)
Compare and contrast the physical address space with the virtual
address space as they relate to different memory mapping techniques in
operating systems.
Section 3 about memory management must have at least two nodes and at least four connecting nodes.
Section 4:
You initially completed this section in your Week 4 interactive
assignment. Review the instructions here and incorporate your peer and
instructor feedback from the Week 4 interactive assignment in your final
version of the concept map.
In this section, continue building the concept map by addressing the following topics concerning files, mass storage, and I/O:
Outline the objectives and functions of file systems management and
the supported operations, including their reliability and performance.
Contrast different directory structures and create unique diagrams
to illustrate an example of each directory structure (similar to Figures
10.9, 10.10, 10.11, 10.12, and 10.13 in your textbook). Insert these
images as nodes of your concept map. To create your diagrams, you can
choose to use a graphics editing software (PowerPoint, Paint, PhotoShop,
etc.), an online mapping software tool (draw.io), or even upload a
photo of a hand-drawn sketch.
Describe different types of input/output devices, distinguishing
between the hardware and software layers and summarizing the integration
across I/O and memory components.
Section 4 about files, mass storage, and I/O must have at least three nodes and at least four connecting nodes.
Section 5:
You initially completed this section in your Week 5 interactive
assignment. Review the instructions here and incorporate your peer and
instructor feedback from the Week 5 interactive assignment in your final
version of the concept map.
In this section, continue building the concept map by addressing the
following topics concerning mechanisms necessary to control the access
of programs, processes, or users:
Outline the goals and principles of domain- and language-based
protection in a modern computer system, and describe how an access
matrix is used to protect specific resources a process can access.
(Consider using a matrix representation to illustrate concepts.)
Describe how security is used to protect programs, systems, and networks from threats.
Section 5 about protection and security must have at least two nodes and three connecting nodes.

For the final section of your project, you will provide a summary
blog post to share any new insights you have gained about operating
systems theory throughout the course and to resolve this focus question:
What are the fundamental concepts that underlie operating systems?
Describe features of contemporary operating systems and their structures.
Discuss how operating systems enable processes to share and exchange information.
Explain how main memory and virtual memory can solve memory management issues.
Explain how files, mass storage, and I/O are handled in a modern computer system.
Outline the mechanisms necessary to control the access of programs or users to the resources defined by a computer system.
Recommend how you will use these concepts about operating systems theory in future courses and/or future jobs.
The Summary Blog Post
Must be 600 to 900 words in length, (not including title and diagrams) and formatted according to APA style
Must use at least five screenshot images to zoom in on sections of the concept map and illustrate your statements.
