The basic concepts and common terms of Windows operating system?

MicrosThe oft Windows 0 operating system is Microsoft's first attempt to use a user graphical interface on the personal computer operation platform. Windows 0 is based on the MS-DOS operating system. Windows 0 essentially announces the end of the MS-DOS operating system.

Windows Operating System (OS) is traditionally the system software responsible for the direct control and management of computer hardware. The functions of the operating system generally include processor management, storage management, file management, device management and job management, etc.

Among many commonly used operating systems, except for individual systems such as QNX and Mach-based UNIX, almost all of them adopt a single-kernel structure, for exampleFor example, most Unix, Linux, and Windows (Microsoft claims that Windows NT is based on an improved micro-corernel architecture, although the theoretical community has objections to it.

Briefly describe the functions of the operating system as follows: First: Provide a human-computer interaction interface. You can imagine what it would be like to use a computer without the software of the operating system. Computer users will face a pile of computer hardware to operate. Early computers were like this, which was controlled by hard switches.

The operating system is a computer program that manages computer hardware and software resources. The operating system needs to handle basic tasks such as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating networks and managing file systems.The operating system also provides an operation interface for users to interact with the system.

Operating System (Operating System): Generally abbreviated as System (OS), let's explain it directly here, that is, it helps us operate the computer. It can be said that without the operating system, 99% of people can't use the computer.

The basic concept of computer operating system

1. The operating system is a computer program that manages computer hardware and software resources, and is also the core and cornerstone of the computer system.

2. The operating system is a computer program that manages computer hardware and software resources, and it is also the core and cornerstone of the computer system.The operating system needs to handle basic tasks such as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating networks and managing file systems.

3. The operating system is the core software of the computer system, which is a set of programs that manage computer hardware and software resources. It provides an infrastructure for coordination and communication between various components of the computer system, including processors, memory, memory, input/output devices, networks and applications, etc.

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

5. The operating system is the computer department.The key components of the system are responsible for managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output equipment, operating the network and managing the file system and other basic tasks.

Summary of knowledge points of Linux operating system

1 and 2 kernel: shell is the user interface of the system, which provides an interface for users to interact with the kernel. In fact, Shell is a command interpreter that interprets user commands and sends them to the kernel for execution.

2. The Linux system generally has 4 main parts: kernel, shell, file system and application. The kernel, shell and file system together form a basic operating system structure, which allows users to run programs, manage files and use the system.

3. The practical commands for maintenance operations on the Linux operating system are included in the /bin and /sbin directories.

4. Summary of the knowledge points of the Linux operating system and the overall introduction of the operating system CPU: Like the human brain, it is mainly responsible for the judgment of relevant matters and the mechanism of actual processing.

5. Linux inherits the design idea of Unix with the network as the core, and is a multi-user network operating system with stable performance. One of the coolest parts of using Linux is that you keep gaining new knowledge over time.
