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). It is the bridge between the operating system and the hardware, performing key functions such as scheduler, memory management and file system.2. Libraries
A library is a set of precompiled codes and functions that can be used by applications. They provide basic functionality such as input/output, memory allocation, and string manipulation.3. Shell
Shell is the command line interface for users to interact with the Linux system. It allows users to enter commands, execute programs and control files. Commonly used shells include Bash, Zsh and ksh.4. System programs
System programs are utilities that perform specific management tasks, such as:5. Desktop environment
The desktop environment provides a graphical user interface (GUI) so that users can easily interact with the system and run app. Popular desktop environments include GNOME, KDE, and Xfce.6. Application software
Application software is a specific application installed and used by users, such as:The above is the detailed content of What parts does a linux system consist of?. For more information, please follow other related articles on the PHP Chinese website!
