In this video, we explore one of the most important parts of operating systems: Process APIs.
How does the OS create new processes?
How does the shell run programs like ls or wc?
What actually happens when you type a command in the terminal?
All of this is powered by three fundamental system calls:
• fork() – create a new process
• exec() – run a new program in a process
• wait() – synchronize parent and child processes
This video walks through these concepts using visual explanations and real code demos.
