Linux operating system (detailed description of operating system Terms)

To put it simply, Linux is a free-of-charge and freely-spread Unix-like operating system. It is a POSIX and UNIX-based operating system that supports multiple users, multitasking, multithreading, and CPUs. It can run major UNIX tool software, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric Unix design philosophy and is a stable multi-user network operating system. It is mainly used on Intel x86 series CPU-based computers. This system is designed and implemented by thousands of programmers around the world. The purpose is to establish a Unix-compatible product that is free of copyright control from any commercialized software and can be freely used all over the world!

Linux is famous for its efficiency and flexibility. The modular design structure of Linux enables it to run on expensive workstations, realize all Unix features on cheap PCs, and have the capability of multi-task and multi-user. Linux is a POSIX-compliant operating system that is obtained free of charge under the GNU Public License. The Linux operating system package includes not only the complete Linux operating system, but also text editor, advanced language compiler, and other application software. It also includes an X-Windows graphical user interface with multiple Window managers. Like using Windows NT, it allows us to operate the system using Windows, icons, and menus.

Linux has the advantages of Unix: stability, reliability, security, and powerful network functions. With the support of related software, services such as WWW, FTP, DNS, DHCP, and e-mail can also be used as routers, use ipchains/iptables to build a NAT and comprehensive firewall.

Linux has many release versions, including RedHat Linux, Debian Linux, and RedFlag Linux.

RedHat LinuxIt supports Intel, Alpha, and iSCSI platforms and has a wide range of software packages. It can be said that RedHat Linux is a very easy-to-use version in the Linux world. It is simple to operate, fast to configure, and the unique RPM module function makes software installation very convenient.

Debian LinuxBased on the standard Linux kernel, it contains hundreds of software packages, such as GNU software, TeX, and X Windows systems. Each software package is an independent module unit and is independent from any specific system version. Everyone can create their own software packages. Debian Linux is a non-commercial LINUX that is made up of volunteers.

RedFlag Linux (Red Flag Linux) is a development product of Linux. It is the first domestically-made operating system version on the server platform that consists of Intel and Alpha chips as CPU developed by the Chinese company. It marks a solid step in China's development of domestic operating systems. Compared with Windows and Unix operating systems, Linux has achieved great development in the server operating system market with its openness and low cost. However, due to the complexity of its operation interface, it is difficult for ordinary PC users to accept it at the moment. GNOME is a dedicated desktop environment project developed by the GNU organization. As an open-source software development result, GNOME, based on the well-compatible CORBA technology, complements the Linux system and gives users more friendly interfaces and freedom to use, check, modify, and distribute. Compared with KDE, which is an open-source graphic user interface, GNOME is more able to reduce the effort of other companies to create Linux desktop applications. GNOME has become a trend software widely favored by industry insiders. After the server version 1.0, desktop version 2.0, and embedded Linux, Hongqi has recently launched a new product, including Hongqi Server 2.0 and Hongqi network business platform. Currently, Hongqi software has laid a solid foundation in the Chinese market and has become a new-generation operating system pioneer.
