Can the device management of the operating system manage all hardware resources? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The device management of the operating system is not the management of all hardware resources. The device management functions of the operating system: buffer management, device allocation, device processing, device independence and virtual devices.

Operating system (Operating System, referred to as OS) is a computer program that manages computer hardware and software resources. The operating system needs to deal with basic tasks such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input and output devices, operating networks and managing file systems. The operating system also provides an interface that allows users to interact with the system.

The function of device Management in operating system

1. Buffer management

In order to alleviate the contradiction of speed mismatch between CPU and Ihammer O devices, improve the utilization rate of CPU and Imax O devices, and improve system throughput, many operating systems set up buffers.

2. Equipment allocation

The basic task of the device assignment is to allocate the required devices to the users according to their Icano requests. If there is still a device controller and channel between the Icano device and the CPU, you also need to assign the appropriate controller and channel to the assigned device.

3. Equipment handling

The device handler is also called the device driver. Its basic task is to realize the communication between CPU and device controller.

4. Device independence and virtual devices

The equipment applied and used by the user to the system has nothing to do with the equipment actually operated.

This is the answer to the question about whether the device management of the operating system can manage all hardware resources. I hope the above content can be of some help to you, if you still have a lot of doubts to be solved. You can follow the industry information channel for more related knowledge.
