**OS Theory Concept Map**

**Purpose:**
The primary goal of the OS Theory Concept Map is to visually outline and make connections between the concepts of operating systems theory. You will build your concept maps incrementally each week as topics are introduced and discussed. In the final week, you will submit your completed concept maps to Waypoint and write a summary blog post to share what you have learned about operating systems theory during this course.

**Focus:**
You will develop an OS Theory Concept Map to answer this focus question: What are the fundamental concepts that underlie operating systems? You will 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:
1. Label the central node to rename it and start building your concept map from it.
2. 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.
3. 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:
1. Categorize, describe, and give examples of the major functions of operating systems.
2. Illustrate the hierarchy of subsystems, components, or subcomponents of operating systems and explain how they interact with one another.
