Linux system consists of kernel (managing hardware, providing API), program library (precompiled code and functions), Shell (command line interface), system program (management tasks), desktop environment (graphical user interface) and Composed of application software (specific applications).

##Linux system composition

Linux system mainly consists of the following parts:

1. Kernel

The kernel is the core of the Linux system and is responsible for managing hardware resources (such as memory, CPU) and providing application programming interfaces (APIs).
