What is linux? What are the advantages? In view of these problems, this article gives the corresponding analysis and answers, hoping to help more friends who want to solve these problems to find a more simple and feasible way.

Is linux a language?

Linux is not a language. Linux is a free-to-use and free-spread Unix-like operating system. It is a multi-user, multi-task, multi-thread 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.

A brief history of Linux

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 be run on PC;DOS, and the source code is strictly kept secret by software manufacturers.

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.

Advantages of Linux

1) Linux consists of many microkernels, and its source code is completely open source.

2) Linux inherits the characteristics of Unix and has very powerful network functions. It supports all Internet protocols, including TCP/IPv4, TCP/IPv6 and link layer topology programs, and can make use of the network characteristics of Unix to develop new protocol stacks.

3) the tool chain of Linux system is complete, and a suitable development environment can be configured with simple operation, which can simplify the development process, reduce the obstacles of simulation tools in development, and make the system portable.
