Operating System Simulation

Five processes (CPU, RAM, DISK, CONSOLE, KERNEL) each running on a different computer, communicating over a custom TCP/IP protocol and running scripts in a custom C-like language. One of the hardest projects due to sync issues, race conditions, and time pressure.

This project models an operating system as five independent C programs: kernel, CPU, memory, console, and filesystem. Each component can run on a different computer and communicates through a custom protocol implemented over TCP sockets.

The simulated system executes scripts written in a purpose-built C-like language. Coordinating distributed processes introduced practical synchronization problems, including race conditions and timing-sensitive failures. The separate source modules make it possible to inspect each subsystem while also showing how scheduling, memory, execution, console input, and storage cooperate as one system.
