Distributions Of Linux: Linux is an operating system, just like Windows, iOS, and Mac OS. In fact, the Linux operating system powers one of the world’s most popular platforms, Android. An operating system is software that controls all of the hardware resources on your computer or laptop. Simply explained, the operating system oversees communication between your software and hardware. The software would not work without the operating system (OS).
What distinguishes Linux from other operating systems?
Linux is similar in many aspects to other operating systems you may have used in the past, such as Windows, macOS (previously OS X), or iOS. Linux, like other operating systems, includes a graphical interface and the same software you’re used to, such as word processors, photo editors, video editors, and so on. In many cases, the designer of a program may have created a Linux version of the same program you use on other systems. In a nutshell, you can use Linux if you can use a computer or other electronic device.
However, Linux differs from other operating systems in a number of fundamental areas. First and foremost, Linux is open source software. The code used to construct Linux is open source and free for anybody to see, alter, and contribute to if they have the necessary expertise.
Although the essential components of the Linux operating system are widely available, there are other Linux distributions that contain a variety of software options. This means that Linux is extremely configurable, as not only software like word processors and web browsers can be replaced. Linux users can also customize essential components such as how the system displays graphics and other user-interface elements.
Different Components Of Linux
Bootloader: The software that oversees your computer’s boot process. For most users, this will just be a splash screen that appears and then disappears before booting into the operating system.
Kernel: This is the one piece of the entire that is truly called ‘Linux’. The kernel is the system’s core, and it oversees the CPU, memory, and peripheral devices. The kernel is the operating system’s most basic level.
Init System: This is a subsystem in charge of booting up the user space and controlling daemons. Systemd is one of the most frequently used init systems, as well as one of the most disputed. Once the bootloader has given over the initial booting, the init system oversees the boot process (i.e., GRUB or GRand Unified Bootloader).
Daemons: These are background services (printing, sound, scheduling, and so forth) that start up either during startup or after you log in.
Graphical Server: This is the subsystem in charge of displaying graphics on your monitor. It is also known as the X server or simply X.
Desktop Environment: This is the component with which the users interact. There are numerous desktop environments from which to pick (GNOME, Cinnamon, Mate, Pantheon, Enlightenment, KDE, Xfce, etc.). Each desktop environment comes with pre-installed programs (such as file managers, configuration tools, web browsers, and games).
Applications: Desktop settings do not provide the complete range of applications. Linux, like Windows and macOS, has tens of thousands of high-quality software titles that are readily identified and installed. Most current Linux distributions feature App Store-like facilities that centralize and simplify application installation. For example, Ubuntu Linux features the Ubuntu Software Center (a rebranding of GNOME Software), which allows you to rapidly browse and install thousands of software from a single spot.
Linux Distributions
Linux comes in a variety of flavors to suit any user. From new users to advanced users, there is a “variant” of Linux to suit your needs. These versions are known as distributions (or, in short, “distros”). Almost any Linux distribution may be downloaded for free, burned to disk (or USB thumb drive), and installed (on as many machines as you like).
Some of the popular Linux distributions are,
Ubuntu
Ubuntu, developed by Canonical, stands as one of the most renowned and user-friendly Linux distributions available. Its primary goal is to offer a seamless experience for individuals new to the Linux ecosystem. With its intuitive interface and an extensive collection of software packages, Ubuntu simplifies the installation and management of applications. Notably, Ubuntu has gained recognition for its unwavering stability and the robust support provided by its vibrant community. As a result, it serves as an exceptional choice for both desktop and server environments.
Fedora
Backed by Red Hat, Fedora is a cutting-edge Linux distribution that places a strong emphasis on incorporating the latest technologies. It strikes a delicate balance between stability and innovation, making it a preferred choice among developers and enthusiasts alike. With the RPM package manager as its foundation and the GNOME desktop environment for a polished and intuitive user experience, Fedora offers a state-of-the-art operating system.
Linux Mint
Linux Mint, a user-friendly distribution built upon Ubuntu, aims to deliver a familiar and intuitive desktop environment, particularly for those transitioning from Windows. With its focus on ease of use, Linux Mint offers a variety of desktop environments, such as Cinnamon, MATE, and Xfce, granting users the freedom to select the one that aligns with their preferences. Supported by a vast and active community, Linux Mint proves to be an exceptional choice for beginners seeking a smooth and hassle-free Linux experience.
Debian
Renowned as one of the oldest and most respected Linux distributions, Debian is celebrated for its steadfast stability, uncompromising security measures, and an extensive software repository. It adheres to a strict open-source philosophy and prioritizes free software. Debian supports multiple desktop environments, including GNOME, KDE Plasma, Xfce, and LXQt, catering to diverse user preferences. With its unwavering commitment to stability and security, Debian remains a popular option for servers and enterprise environments.
Arch Linux
As a lightweight and highly customizable distribution, Arch Linux follows a “do-it-yourself” approach. It offers a minimal base system, empowering users to build their ideal computing environment from scratch. Leveraging the Pacman package manager and the Arch User Repository (AUR), Arch Linux provides access to a vast collection of software packages. While Arch Linux demands a higher level of technical expertise, it offers unparalleled flexibility and exceptional performance, making it a favored choice among advanced users.
openSUSE
openSUSE stands as a community-driven Linux distribution, renowned for its stability, impressive performance, and user-friendly nature. It offers two primary editions: Leap, a regular release focused on delivering a stable experience, and Tumbleweed, a rolling release that constantly provides the latest software updates. A notable feature of openSUSE is the YaST control center, which offers an intuitive interface for system configuration and administration. With its commitment to reliability and ease of use, openSUSE remains a top contender in the realm of Linux distributions.
Difference Between Unix & Linux
Unix is an operating system developed at Bell Labs in the 1970s by Ken Thompson, Dennis Ritchie, and others. Unix and Linux are quite similar in many ways, and Linux was designed to be indistinguishable from Unix. Both have similar interface tools, development tools, filesystem layouts, and other critical components. However, not all Unixes are open source and free.
Several operating systems have been developed over the years in an attempt to be “unix-like” or “unix-compatible,” but Linux has been the most successful, considerably outperforming its predecessors in popularity.
