About Linux

Linux, one of the most popular operating systems around, can be found used in supercomputers, cars, desktops, and enterprise servers. Ever since its introduction in the mid-1990s, Linux has reached many people across the globe. It is so common that one can find Linux everywhere. Your car, phone, thermostat, refrigerator, televisions, and Roku devices are installed have Linux installed. The operating system is also responsible for running the top 500 supercomputers in the world, most of the Internet, and the stock exchanges around the world.

Besides being the most popular operating system for desktops and servers, Linux is also considered to be one of the most trustworthy and safe operating systems across the globe.

So, what is Linux?

Linux is an operating system just like Windows, MAC operating system, and iOS. It might come as a surprise to many that the most popular platforms across the globe, Android, is powered by the Linux operating system. An operating system can be understood as a software that is responsible for managing all the hardware resources on the desktop or the laptop. To understand it in a simpler way, the operating system is the bridge that helps in developing communication between the software and the hardware of your desktop or laptop. The absence of software will not let the software in the system will not be able to function.

There are various pieces that form the Linux operating system. These include:

The bootloader: This is the software responsible for managing the boot process of the computer. Many users this must just be a splash screen popping up on their screen which goes away to the boot into the operating system.

The Kernel: This is the core system that is responsible for managing the CPU, the peripheral devices, and the memory. The Kernel is the lowest level of the Linux operating system.

The Init system: This another piece of the Linux operating system that bootstraps the userspace. The controlling daemons are responsible for providing charging to it. The most commonly used Init system across the globe is systemd, which has also been the most controversial one. Once the initial booting is done and is passed on from the bootloader, like GRUB or GRand, the Init system comes into play and manages the boot process.

Daemons: Usually, these are the services that run in the background such as printing, scheduling, sound, etc. These services either start during the boot process or after the user log into the computer.

Graphical server: This sub-system is responsible for displaying graphics on the system monitor. Commonly, this is known as the X server or simply X.

Desktop environment: This piece of the Linux operating system is what the users usually interact with. There are many desktop environments available to interact with. These include:

  • Mate
  • Cinnamon
  • KDE
  • Enlightenment
  • Xfce

  • All these desktop environments include built-in applications like configuration tools, file managers, games, and web browsers.

    Applications: Desktop environments lack a wide range of apps. Similar to other operating systems like Windows and MAC operating system, Linux also offers thousands of software that are of supreme quality and can be easily installed and found. Mostly all modern Linux distributions include tools like the App Store that help in centralization and simplification of the installation process. Like, the Ubuntu Linux comes with Ubuntu Software Center. This aids in the quick search of thousands of apps and helps their installation from one location that is centralized.
