1.What is a proprietary os for desktop and laptop computers?

Operating system (OS) is a computer program that manages and controls computer hardware and software resources. It is the most basic system software that runs directly on "bare metal", and a collection of system software that controls the operation of other programs and provides users with an interactive operating interface. Any other software must be supported by the operating system to run. What are the proprietary operating systems for laptops and desktops? The answer is windows. All versions of the operating system that Microsoft releases have never been divided between laptops and desktops.

Why does a laptop-specific operating system appear? This is because the hardware configuration of a laptop is slightly different from that of a desktop computer. For example, some laptop shortcut keys and other function keys cannot be used without drivers. After installing the operating system, if you want to use these functions, To install these drivers again, some system producers add notebook-specific drivers to the Microsoft operating system for the convenience of users, which forms an operating system specially used for notebooks.

Because the laptop-specific operating system has more drivers than ordinary operating systems, it can be used for desktop computers, but some laptops are not very good for desktop systems because of the lack of drivers required for laptops.

The main functions of the operating system

• Processor management

The most basic function of processor management is to handle interrupt events. The processor can only detect interrupt events and generate interrupts but not process them. Once the operating system is configured, various events can be processed. Another function of processor management is processor scheduling. There may be one or more processors, and different types of operating systems will adopt different scheduling strategies for different situations. Also called process management.

• Memory management

Memory management mainly refers to the management of internal memory. The main task is to allocate memory space, ensure that the storage space occupied by each job does not conflict, and make sure that each job does not interfere with each other in its own storage area.

• Device management

Device management refers to the management of various peripheral devices (referred to as: peripherals), including allocation, startup, and troubleshooting. The main task is: when the user uses the external device, he must put forward a request, and it can be used after the operating system is uniformly allocated. When the user's program runs to use a peripheral device, the operating system is responsible for driving the peripheral device. The operating system also has the ability to handle peripheral interrupt requests.

• File management

File management refers to the management of information resources by the operating system. In an operating system, a portion of management information responsible for access is called a file system. A file is an ordered collection of a logically complete set of related information, each with a filename. File management supports operations such as file storage, retrieval, and modification, as well as file protection functions. Operating systems generally provide file systems with strong functions, and some also provide database systems to manage information.

• Job management

A separate operation that each user requests the computer system to perform is called a job. Job management includes job input and output, job scheduling and control (controlling job running steps according to user needs).
