What are the Several Parts of Linux?

Linux, a popular operating system consists of several parts or pieces that are briefly depicted below:

• Bootloader: It is the software that is responsible for managing the process of booting a computer. Most of the users recognize it as a simple splash screen that suddenly pops up on the screen and goes away eventually for conducting the booting process in the operating system.
• Init system: this is basically a sub-system that helps in rebooting the space of the user and is charged with regulating daemons. Systemd is one of the most hugely used Init systems that are also one of the most debatable. This system manages the process of booting as soon as the initial booting process is transferred from the Bootloader.
• Kernel: This entire piece is termed as ‘Linux’. It is the core of the system and controls the CPU, peripheral devices, and memory. This is the lowest level of the operating system.
• Daemons: These are nothing but background services such as sound, printing, scheduling, etc that can start up during the booting process or right after logging into the desktop.
• Desktop environment: This part is the actual piece with which users interact. Several desktop environments are available to select from such as Cinnamon, GNOME, Enlightenment, Mate, KDE, Pantheon, Xfce, etc. Every single desktop environment consists of in-built applications like configuration tools, file managers, games, and web browsers.
• Graphical server: This is also a sub-system that helps in displaying the graphics on the desktop screen. It is commonly termed the X server or only X.
• Applications: Desktop environments never provide the complete range of applications. Similar to macOS and Windows, this operating system provides thousands of superior-quality software titles that can be found and installed easily. Most of the advanced distributions of Linux involve tools like application stores that unify and simplify the installation of applications.

How is Linux used?

Linux is used in the following ways:

• Server OS: It works as server OS for database servers, web servers, email servers, file servers, and any other kind of shared server. This operating system is designed and developed for supporting multithreading and high-volume applications. So, it is nicely suited for each type of server application.
• Desktop OS: it is for computing personal productivity. It is a freely available and open-source desktop environment that is beneficial for users who like it to commercial OSes.
• Appliance or embedded device OS: It is important for systems that need the limited function of computing. This operating system is utilized as an embedded OS for multiple applications such as automotive environment systems, household appliances, and appliances for the network file system.
• Headless Server OS: It is beneficial for systems that do not need any GUI (Graphical User Interface) or directly connected keyboard and terminal.
• Network OS: It is used for switches, routers, home networking devices, domain name systems, and more.
• Cloud OS: Most of the providers of cloud computing offer access to instances of cloud computing.
• Software development OS: It is used for the software development of enterprises.
