Linux Introduction

Linux, the full name is GNU/Linux, is a set of Unix-like operating systems that are free to use and freely disseminated. It is a multi-user based on POSIX and Unix , multi-tasking, multi-threading and multi-CPU operating systems.

With the development of the Internet, Linux has received support from software enthusiasts, organizations, and companies around the world. In addition to maintaining a strong momentum of development in servers, it has also 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 Linux according to their own needs to maximize it to meet the needs of users.

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, Linux is not only used as a server by network operation and maintenance personnel, it is also used as a server, and even as a network firewall. This is a highlight of Linux.

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, with high flexibility, powerful functions, and low cost. In particular, the network protocol stack is embedded in the system and can function as a router after proper configuration. These characteristics make Linux an ideal development platform for developing routing and switching equipment.

Advantages:

1. Linux is composed of many microkernels, and its source code is completely open source;

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

3. The Linux system tool chain is complete, and a suitable development environment can be configured with simple operations, which can simplify the development process, reduce obstacles to simulation tools in development, and make the system highly portable;
