The Linux system consists of three main components: the kernel, which is responsible for hardware management and system functions; Shell, which provides a command line interface for users to interact with the system; application software, which is a variety of programs that users use daily.
The three parts of the Linux system
The Linux system consists of the following three main parts:
1. Kernel
The kernel is the core of the Linux system and is responsible for managing basic system functions such as hardware resources, process scheduling, and memory management. It acts as a bridge between software and hardware and ensures that all components function properly.
2. Shell
Shell is a command line interface that allows users to interact with Linux systems. It provides an interface for users to enter commands to control the system and perform tasks. Commonly used shells include Bash, Zsh, and Csh.
3. Application software
Application software is a software program that users run on a Linux system. These programs include various applications such as word processors, spreadsheets, web browsers, media players, and more. Application software is stored in user space and runs separately from the kernel.
