Main functions and programming implementation of operating system

The core function of the operating system is to manage computer hardware resources and provide an interface between the user and the computer system. It is the most basic software layer in a computer system and is responsible for coordinating and controlling the interaction between hardware, software and users. The following will introduce the main functions of the operating system in detail and provide relevant programming implementation examples.

1. Process Management
   Process management is one of the core functions of the operating system. It is responsible for creating, scheduling, and terminating processes, providing resource allocation and mutual exclusion mechanisms for processes, and handling inter-process communication and synchronization. Here is a simple example showing how to create and schedule processes in Python:

import multiprocessing

def worker():
    print("Worker process")

if __name__ == "__main__":
    p = mu
