  • Graphical User Interface (GUI)

Linux distributions also include a user interface called a graphical user interface (GUI) for individuals who want an appealing user interface.  With its icons, windows, and menus, the GUI provides an easy-to-use interface that makes it simpler for novices to traverse and communicate with the system.  Linux GUIs are available in a variety of flavors, including GNOME, KDE, and Xfce, each of which offers a unique user experience.

  • Linux File System

A hierarchy file system is used by Linux to arrange directories and files in a tree-like form.  The initial location is the root directory (“/”), from which subdirectories branch out.  This file system makes it possible to store, handle, and retrieve data quickly while maintaining its confidentiality and availability.

  • Package Management

Package management systems are used by Linux distributions to make it easier to install, update, and remove software packages.  Such package administrators offer an organized and effective approach to handling software, dependencies, and system upgrades.  Examples include APT (Advanced Package Tool) and YUM (Yellowdog Updater, Modified).

  • Linux Shell and Shell Scripting

Users can communicate with the operating system using the Linux shell, which is an interpreter for commands.  It offers a command-line interface through which users may run programs, enter commands, and automate operations.  Shell scripting enables the automated execution of intricate procedures and the development of unique workflows by allowing users to write scripts that combine several commands.

  • Linux in Server Environments

Due to its reliability, safety, and flexibility, Linux has an important role in server settings.  Operating systems based on Linux are used on numerous web servers, database servers, and cloud servers.  Linux is a great option for delivering crucial applications and services due to its durability and productivity.
