The operating system was introduced in the first generation of computers

4th generation, LSI.

Second generation. Basically, an operating system is a program, a program between the computer hardware and the computer user, the developer through which the user operates the computer, and the developer writes the program with the interface it provides. The operating system is probably the most important (or the most complex) program, basically, it determines what we can do with the computer and how we can use the computer, of course, the software is ever-changing, constantly evolving, but no matter what kind of operating system the software runs, it must be limited by the functions provided by the operating system.

In other words, it can only somersault in the circle drawn by the operating system.

The first generation of computers was the vacuum tube computer (circa 1945 1959) that did not have an operating system, such as the first computer ENIAC that came out in 1945, and that thing could only do 5,000 additions and subtractions per second, which was not as good as the cheapest calculator on the floor today.

The second generation of computers was the transistor computer (circa 1959 1964), and the computers of this era were all so-called mainframes, represented by IBM's 1403 machine, which had much faster computing power than the first generation, reaching tens of millions of times per second, a number that looked pretty good, and if the operating system was simple enough, it could run.

It was at this time that the operating system appeared (there is also a saying that simple operating systems appeared in the mid-fifties!). It was in this era that a particularly noteworthy operating system was already in the making, the famous OS 360.

Second generation. In the beginning, computers did not have operating systems, and people controlled computers through various buttons, and later came assembly language, where operators entered programs into computers through perforated paper tapes for compilation. These computers with built-in languages can only be run by the producers themselves to write programs, which is not conducive to the sharing of programs and equipment.

In order to solve this problem, the operating system appeared, so that the common use of programs and the management of computer hardware resources were well realized.

The first generation was machine language, and it wasn't until assembly language came out that there was an operating system and could be batched. In this way, it is easy for people to read the completed program or understand the function that the program is performing, and it becomes easier to fix bugs and operate and maintain existing programs, which is what we call assembly language, which is the second generation of computer language.

With the development of computing technology and large-scale integrated circuits, microcomputers have developed rapidly. Computer operating systems began to appear in the mid-70s of the 20th century. In the United States, in 1976, Digital Research Software developed an 8-bit CP M operating system.

This system allows users to control and manage the system through the keyboard of the console, and its main function is to manage file information to achieve automatic access to files on other devices or hard disks. Since then, some 8-bit operating systems have adopted a CP M architecture.

The operating system appeared in the 3rd generation of computers.

Since the 90s, Microsoft has launched various series of Windows operating systems such as Windows OS. It is not only the most widely used operating system for desktop computers in the past 20 years, but also completely ends the history of system software dependent on hardware.

Since then, software has become the core of informatization and a sunrise industry with independent development. In the early 90s, Linux, developed by Linus Torvalds, became another milestone in the history of operating system development, contributing to the development of open source operating systems. To date, Linux has a large user base and a wide range of applications, becoming one of the mainstream operating systems currently on a par with UNIX and Windows.

The function of the operating system

The role of the operating system in a computer system is to manage system resources and provide control over program execution. It provides user-friendly human-computer interaction and rich functional support for other software.

Computer system resources include hardware resources and software resources, and hardware resources refer to the hardware equipment that makes up a computer.

Such as processors, main memory, tape storage, printers, monitors, keyboard input devices, etc., software resources mainly refer to various data and programs stored in the computer. Both the hardware and software resources of the system are allocated and scheduled by the operating system according to user needs and system status.

System software. An operating system is a type of system software for a computer system. In a computer, the operating system is the most basic and important basic system software.

From the perspective of a computer user, the computer operating system is reflected in the various services provided to it; From the programmer's point of view, it mainly refers to the interface or interface for user login; From the designer's point of view, it refers to the connections between the various modules and units.

Computers began to have operating systems from the second generation of computers (probably the 60s of the last century), which were not called operating systems at that time, but were only supervised programs on batch systems, which were regarded as the predecessors of operating systems.

The computer is one of the most advanced scientific and technological inventions in the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality.

Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises and institutions.

Entering the homes of ordinary people has become an indispensable tool in the information society.

The conversational language, or basic, emerged in the 60s of the 20th century and became popular in the 70s.

The earliest operating system was supposed to be a batch system in the early 60s.

Like OS 360, Multics, and the famous Unix also appeared in the 60s.

The third generation, small and medium-scale integrated circuits.

Remember, it's small, medium-sized, not large-scale, super-large)

In the first generation of computers, programmers needed to manually control the computer's hardware to accomplish a specific task, which was very inefficient, error-prone, and required a lot of time and effort to complete a task.

With the advent of the second generation of computers, computer hardware technology has been greatly improved, and computers can automatically perform some repetitive tasks, which requires a more efficient way to control the hardware of computers, so the Zheng Bang operating system came into being.

The advent of operating systems can greatly improve the efficiency of computers and provide a more user-friendly interface, making it easier for users to interact with computers. With the continuous development of computer technology, the operating system is also constantly evolving and developing, and has gradually become the most important part of the computer system.

It is important to note that in the first generation of computers, although there was no operating system, people used programming languages to control the computer and achieve specific tasks. Therefore, the advent of operating systems is not the only advance in computer systems, but an important aspect of the development of computer technology.

It seems to have been used since the second generation.
