What is the linux system kernel?

Linux is an open source computer operating system kernel. It is a Unix-like operating system written in C language and compliant with POSIX standards.

#Linux was first developed by Linus Torvalds of Finland in an attempt to provide a free Unix-like operating system on the Intel x86 architecture. The project started in 1991, with some Minix hackers assisting in the early days of the project, and today countless programmers around the world are helping the project for free.

Linux kernel[kernel] is the bottom layer of the entire operating system. It is responsible for driving the entire hardware and providing core functions required by various systems, including firewall mechanisms and whether to support LVM. Or file systems such as Quota, etc. If the kernel does not recognize a certain latest hardware, then the hardware cannot be driven and you cannot use the hardware.

The real working thing of a computer is actually the hardware. For example, the CPU is used for numerical calculations, the hard disk is used for data storage, the display adapter is used for graphics display, the sound effect chip is needed for music sound, and a network may be needed to connect to the Internet. Cards and so on. The kernel is what controls how these chips work.
