This article will explain in detail the definition and characteristics of the Linux system. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Linux is a command line operating system, which has many powerful functions. Its commands control simple disk operations, file access, complex multimedia images and streaming media file production. There is nothing wrong with using Linux for low-configuration hardware. However, for users who do not want to invest in hardware, there should be no choice but to continue to use the old XP or replace it with a Linux system. So what about the linux operating system? what are its features?

Linux system definition

Linux is a free-to-use and free-spread Unix-like operating system. It is a multi-user, multi-task, multi-threaded and multi-CPU operating system based on POSIX and UNIX. It runs major UNIX tools, applications, and network protocols. It supports 32 bit and 64 bit hardware. Linux inherits the design idea of Unix with network as the core, and is a multi-user network operating system with stable performance.

Characteristics of Linux system

1. Support multiple platforms. Linux can run on a variety of hardware platforms, such as those with x86, 680x0, SPARC, Alpha and other processors. In addition, Linux is an embedded operating system that can run on PDAs, set-top boxes or game consoles. The Linux 2.4 kernel released in January 2001 has been able to fully support Intel 64-bit chip architecture. Linux also supports multiprocessor technology. Multiple processors work at the same time, which greatly improves the performance of the system.

2. Multi-user and multi-task. Linux supports multiple users, and each user has their own special rights for their own file devices, which ensures that each user does not affect each other. Multitasking is now the most important feature of computers. Linux enables multiple programs to run simultaneously and independently.

3. Fully compatible with POSIX1.0 standard. This makes it possible to run common DOS and Windows programs under Linux through the corresponding simulator. This lays the foundation for users to move from Windows to Linux. When many users think about using Linux, they think about whether the programs that used to be common under Windows will work properly, which relieves them of their doubts.

4. Good interface. Linux has both character interface and graphical interface. In the character interface, the user can input the corresponding instructions through the keyboard to operate. It also provides a X-Window system similar to the Windows graphical interface, which can be manipulated by users using the mouse. In the X-Window environment is similar to in Windows, it can be said to be a Linux version of Windows.

5. It's completely free. Linux is a free operating system, users can get it free of charge through the Internet or other means, and can modify its source code at will. This is what other operating systems cannot do. Because of this, countless programmers from all over the world have participated in the modification and writing of Linux, and programmers can change it according to their own interests and inspiration, which makes Linux absorb the essence of countless programmers and grow.

Linux operating system supports multiple platforms, can perform multi-user and multi-task operations at the same time, and the system is fully compatible with POSIX1.0 standards, has a good interface, and the most important thing is that the system is completely free, so that users can get a perfect experience in the process of use, debug according to their own requirements, and meet the various needs of users. The system is worth using by the majority of users.

On the definition and characteristics of the Linux system to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
