Code Explanation:

This piece of code intricately demonstrates three fundamental operations of operating systems: file management, process management, and memory management.

• File Operations: Initially, it creates a file named sample_os_operations_file.txt, writes some data to it, reads the data back, prints it to the console, and then deletes the file. This explores how operating systems handle file creation, reading, writing, and deletion.

• Process Creation and Management: The code then showcases process creation and management by initiating a secondary thread (mimicking a lightweight process) that executes the file_operations function again. This demonstrates how operating systems can execute and manage multiple processes concurrently.

• Memory Management Simulation: Lastly, it simulates memory allocation and deallocation. It predetermines a ‘memory block’ as a list, attempts to place some ‘data’ in a specific index (mimicking allocation), and later removes it (mimicking deallocation). This shows a simplified version of how operating systems manage memory allocation for applications and processes.

Each of these operations plays a crucial role in understanding how operating systems function and manage computer resources. By diving into these programmable examples, readers can grasp a more hands-on understanding of OS operations.
