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. Linux can be used as both a server and a network firewall, which is a highlight of Linux.
Linux has the characteristics of open source, no copyright, and many 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.
