Structure of operating system with suitable example

An operating system (OS) is a software that manages computer hardware and software resources and provides common services for computer programs. The structure of an operating system can be divided into four main components: 

1. Kernel

2. Device drivers

3. System libraries

4. User interface 

Here is an example diagram of the structure of an operating system:

```

      +-------------------------+

      | User Application |

      +-------------------------+

                  |

                  |

                  v

      +-------------------------+

      | System Libraries |

      +-------------------------+

                  |

                  |

                  v

      +-------------------------+

      | Operating System |

      | Kernel |

      | Device Drivers |

      +-------------------------+

                  |

                  |

                  v

      +-------------------------+

      | Hardware |

      +-------------------------+

```

The user application layer is where the user interacts with the operating system, and the system libraries provide a set of functions that the application layer can use. 

The kernel is the central part of the operating system that manages the system resources and provides the core services. It interacts directly with the hardware through device drivers, which are modules that control specific hardware devices such as the keyboard, mouse, or printer. 

The hardware layer consists of the physical components of the computer, such as the CPU, memory, and hard drive. 

Overall, the structure of the operating system is hierarchical, with each layer building on top of the previous layer to provide a complete system that manages and controls the computer's hardware and software resources.
