Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and Unix. It can run major Unix software tools, applications and network protocols.

It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.

Linux not only has stable system performance, but also is an open source software. Its core firewall components have high performance and simple configuration, ensuring system security. In many corporate networks, in order to pursue speed and security, the Linux operating system is not only used as a server by network operation and maintenance personnel. Linux can be used as both a server and a network firewall, which is a highlight of Linux.

Compared with other operating systems, Linux has the characteristics of open source, no copyright, and a large number of users in the technical community. Open source allows users to tailor it freely, has high flexibility, powerful functions, and low cost.

In particular, the network protocol stack is embedded in the system, and the function of the router can be realized after appropriate configuration. These characteristics make Linux an ideal development platform for developing routing and switching equipment.

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

Linus Torvalds, a second-year student at the University of Helsinki in Finland, is one of them. Based on absorbing the essence of MINIX, Linus wrote his own Linux operating system in 1991, version Linux0.01, which is The beginning of the Linux era. He used the core of Unix, removed the complicated core programs, rewritten it into an x86 system suitable for general computers, and put it on the Internet for everyone to download. In 1994, he launched the complete core Version 1.0. Since then, Linux has gradually become a fully functional and stable system. operating system and is widely used.
