What is the interface of the operating system?

The operating system is the interface between the user and the computer. Within the computer, the operating system manages various resources of the computer system and expands the functions of the hardware; externally, the computer operating system provides a good human-computer interface to facilitate users to use the computer. It plays a connecting role in the entire computer system, so the computer operating system is the interface between the user and the computer.

The computer operating system is the interface between the user and the computer. In the computer, the operating system is the most basic and important basic system software;

It can make the computer system coordinate, efficient and Work reliably, including processor management, memory management, device management, file management, job management and other functional modules. The most basic function of processor management is to handle interrupt events, also called process management. The main task of memory management is to allocate memory space. , to ensure that there is no conflict in the storage space occupied by each job;

Device management is responsible for managing various peripheral devices, including allocation, startup and fault handling, etc. File management refers to the management of information resources by the operating system. Jobs Management includes job input and output, as well as job scheduling and control.

Development History

Throughout the history of computers, operating systems are closely related to the development of computer hardware. The original intention of the operating system was to provide simple work sequencing capabilities, but it gradually evolved to assist in updating more complex hardware facilities. Starting from the earliest batch mode, the time-sharing mechanism also appeared. When the multi-processor era came, the operating system also added multi-processor coordination functions, and even distributed system coordination functions. Other aspects of evolution have been similar. On the other hand, the operating system of personal computers follows the growth path of mainframes. As the hardware becomes more and more complex and powerful, it gradually realizes functions that were only available on mainframes in the past.

Since the birth of the first electronic computer in 1946, each generation of its evolution has been aimed at reducing costs, reducing size, reducing power consumption, increasing capacity and improving performance. With the development of computer hardware, At the same time, it also accelerated the formation and development of the operating system (OS for short).

The original computer did not have an operating system, and people controlled the computer through various buttons. Later, assembly language appeared, and the operator entered the program into the computer through perforated paper tape for compilation. These computers with built-in languages ​​can only be run by the producers writing their own programs, which is not conducive to the sharing of programs and equipment. In order to solve this problem, the operating system emerged, which can easily realize the sharing of programs and the management of computer hardware resources.

With the development of computing technology and large-scale integrated circuits, microcomputers have developed rapidly. Computer operating systems began to appear in the mid-1970s. In the United States in 1976, DIGITAL RESEARCH Software Company developed an 8-bit CP/M operating system. This system allows users to control and manage the system through the keyboard of the console. Its main function is to manage file information to achieve automatic access to other device files or hard disk files. Some 8-bit operating systems that have appeared since then mostly use the CP/M structure.
