Fundamentals of Operating System Concepts

Process Management and the Lifecycle of Execution

Define a Process and Its Core Components • Control the Process Lifecycle via System Calls • Orchestrate Concurrent Execution via Context Switching

CPU Scheduling Policy and Mechanism

Define the Goals and Metrics of CPU Scheduling • Analyze Core Preemptive and Non-Preemptive Scheduling Policies • Implement Multi-Level Feedback Queue Scheduling

Concurrency and Threading

Model Thread-Based Concurrency • Diagnose Concurrency Hazards • Implement Thread Synchronization

Synchronization and Deadlock Prevention

Identify Concurrency Issues in Shared Memory • Implement Synchronization Using Core Primitives • Prevent and Handle System Deadlocks

Physical Memory Management

Model the State of Physical Memory • Isolate Processes Using Hardware Protection • Apply Contiguous Allocation Strategies

Virtual Memory and Paging

Divide Memory Using Paging • Translate Virtual to Physical Addresses • Enable Memory Larger Than RAM

File System Structure and Implementation

Model the Logical Structure of a File System • Implement File Allocation Strategies on Disk • Manage Disk Space and Ensure Data Integrity

Input, Output, and Device Drivers

Analyze the Hardware-Software Interface for I/O • Deconstruct the I/O Software Layer • Optimize I/O Performance and Management

Security, Protection, and Virtualization

Enforce System Protection • Defend Against System Threats • Virtualize Hardware with Hypervisors
