Operating Systems Ops

Master the OS layer. Deep dive into process management, virtual memory, scheduling algorithms, and concurrency primitives in Linux/Unix.

The OS manages everything your code relies on. This course covers Operating System theory and implementation. You will understand how the kernel manages Processes and Threads, the mechanics of Virtual Memory and Paging, and how Scheduling algorithms allocate CPU time. We explore Inter-Process Communication (IPC), file systems, and deadlock prevention. Essential knowledge for systems programmers, SREs, and anyone optimizing code close to the metal.
