What is not included in the management functions of the operating system

The four major management functions of the operating system do not include "save management". The functions of the operating system include processor management, job management, storage management, device management and file management; there is a set of implementation systems in the core of the operating system. The functional process includes task management, interface management, human-computer interaction, graphical interface, voice control and virtual reality, etc.

#The management function of the operating system does not include "save management".

The functions of the operating system include processor management, job management, storage management, device management and file management.

The functions of the operating system are as follows:

(1) Processor management (process management): In essence, it is the management of the "time" of the processor execution, that is, how to Really and reasonably allocate the CPU to each task process control, process synchronization, process communication and scheduling.

(2) Storage management: The essence is the management of storage "space", which mainly refers to the definition of memory management, memory allocation, memory protection, memory expansion, address mapping, logical address, and physical address.

(3) Device management: The essence is the management of hardware devices, including the allocation and startup of input/output devices, completion and recycling buffer management, device allocation, device processing, device independence and virtual devices .

(4) Information management (file management): file storage space management, directory management, file read/write management and access control.

(5) User interface (job management): Command interface, graphical interface, and system calls are the only interfaces provided by the operating system to software developers, who can use it to use system functions. The core of the operating system has a set of processes (subprograms) that implement system functions. System calls are calls to the above processes, including task management, interface management, human-computer interaction, graphical interfaces, voice control, and virtual reality.
