Preface
Different systems are often used in work. For example, the longest used is the windows system. Commonly, such as Windows10 7 xp, etc., Windows systems are mainly run on personal computers. Although there are also server versions, the market share is not hit, while the liunx system The server-side share is very high, and it has incomparable advantages over Windows systems, such as stability and security.
1. What is LINUX?
Linux is an operating system. The Linux kernel was originally written by Finn Linus Torvalds out of personal hobbies when he was studying at the University of Helsinki.
Linux is a free-to-use and freely spread Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX.
Linux can run major UNIX tools, software, applications, and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits Unix's network-centric design philosophy and is a multi-user network operating system with stable performance.
Two, LINUX each release
The simple point of the Linux distribution is to package the Linux kernel and application software. At present, the more well-known distributions on the market are: Ubuntu, RedHat, CentOS, Debian, Fedora, SuSE, OpenSUSE, Arch Linux, SolusOS, etc. The
most used distributions on the market are centos ubuntu SUSE and Red Hat. In the future, my articles are mainly based on centos.
The difference between LINUX and WINDOWS
Four LINUX kernel
The kernel of the Linux system is the same regardless of the release version. The liunx kernel is developed by Linus Torvalds, the father of Linux, and his team releases kernel updates.
Linux itself is an open source system, anyone can be a developer and contribute source code to the code base, but the kernel only has Linus Torvalds to compile
