Understand what an operating system really does—from booting your laptop to managing multiple apps. We'll explore OS types, system calls, and the heart of any OS: the process. You'll learn how processes are born, run, and die, and how the OS switches between them seamlessly.

The CPU is the most precious resource—how does the OS decide which process gets it next? We'll explore scheduling algorithms that balance speed and fairness. Then, we dive into how processes talk to each other without stepping on toes, using synchronization tools like semaphores.
Memory is limited—how does the OS fit multiple programs into RAM? We'll start with simple contiguous allocation and its problems, then move to paging and virtual memory. You'll understand why your laptop can run Chrome with 100 tabs despite limited RAM.
Files are how we store data permanently—from your resume to a movie. We'll explore how the OS organizes files on disk, allocates space, and manages I/O devices. You'll learn why some files are stored in 'blocks' and how your pen drive is formatted.
Deadlocks are the worst nightmare—processes waiting forever for each other. We'll learn how to prevent, avoid, and recover from deadlocks. Then, we dive into disk scheduling algorithms that minimize seek time, and understand disk structure, formatting, and bad blocks.
