Is the linux system free? Perhaps many people do not understand, in order to let you understand better, the editor summed up the following content, I hope you can gain something according to this article.

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. The GPL open source protocol was formally adopted in 1994.

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.

With the development of the Internet, Linux has received support from software enthusiasts, organizations and companies all over the world. In addition to maintaining a strong development momentum in the server operating system, it has made great progress in personal computers and embedded systems.

Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve the operating system according to their own needs to maximize meet the needs of users.

Linux is not only a stable system, but also an open source software. The core firewall components have high performance and simple configuration, which ensures the security of the system.

In many enterprise networks, in order to pursue speed and security, Linux operating system is not only used as a server by network operators, Linux can be used not only as a server, but also as a network firewall is a bright spot of Linux.

Compared with other operating systems, Linux has the characteristics of open source, no copyright and many users in the technical community. Open source enables users to cut freely, with high flexibility, powerful functions and low cost.

In particular, the network protocol stack is embedded in the system, which can realize the function of the router after proper configuration. These characteristics make Linux an ideal development platform for developing routing switching devices.

The birth, development and growth of Linux operating system always depend on five important pillars: Unix operating system, MINIX operating system, GNU project, POSIX standard and Internet network.

In the 1980s, with the continuous improvement of the performance of computer hardware and the expansion of the market of PC, the main operating systems available for computers at that time were Unix, DOS and MacOS.

Unix is expensive, cannot run on PC;DOS, and the source code is strictly kept secret by software vendors; MacOS is an operating system designed specifically for Apple computers.

At this time, the field of computer science urgently needs a more perfect, powerful, cheap and completely open operating system. Because there were few typical operating systems for teaching, AndrewS.Tanenbaum, an American professor in the Netherlands at that time, wrote an operating system called MINIX to explain to students how the operating system works.

Although MINIX is good, it is only a simple operating system for teaching purposes, not a powerful practical operating system, but the biggest advantage is open source code.

Computer students all over the world delve into the MINIX source code to understand the MINIX operating system running in their computers. Linus Torvalds, a sophomore at the University of Helsinki in Finland, is one of them. On the basis of absorbing the essence of MINIX, Linus wrote his own Linux operating system in 1991, the version is Linux0.01, which marks the beginning of the Linux era.

He uses the core of Unix, removes complicated core programs, rewrites it into an x86 system suitable for general computers, and puts it on the network for everyone to download. In 1994, he launched a complete core Version1.0. Since then, Linux has gradually become a fully functional and stable operating system, and has been widely used.

About 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.
