CP M operating system.

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 earliest operating system of the PC was the DOS system, which was later replaced by Microsoft's Windows system.

DOS is an abbreviation for Disk Operating System, which means "disk operating system". DOS is a class of operating system on a personal computer. For 15 years, from 1981 to 1995, DOS was a major player in the IBM PC-compatible market.

Moreover, if some DOS-based versions of Microsoft Windows, such as Windows and ME, are included, then their commercial life can be calculated to be at least 2000 years.

There are two common types of DOS: IBM's PC-DOS and Microsoft's MS-DOS, which have the same functions and command usage formats, and we commonly use MS-DOS.

Since the advent of DOS in 1981, the version has been constantly updated, from the initial upgrade to the latest ME system), the highest version of pure DOS is, and the new version of DOS since then is provided by the Windows system, and does not exist alone.

It's hard to say what the earliest operating system was, after all, the operating system at the beginning didn't have a long lifespan, and some were not announced at all.

The first large-scale and widely used operating system was the UNIX series (1970), and DOS (1981) was the first operating system designed for PCs and widely used.

The earliest time-sharing operating system was:

The operating system is the support platform of the application system, and the operating system is the core of the system software, which is the only software that can be directly installed on the hardware.

1. Operating system.

An operating system (OS) is a computer program that manages computer hardware and software resources, and is also the core and cornerstone of a computer system.

The operating system handles basic tasks such as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating the network, and managing the file system. The operating system also provides an interface for users to interact with the system.

2. Application system.

It is generally composed of computer hardware system, system software, and application software. The basic hardware system of a computer consists of combinators and controllers, memory, peripheral interfaces, and peripherals. System software includes operating systems, compilers, database management systems, various high-level languages, etc.

The application software consists of general support software and various application packages.
