The Linux operating system comprises several different pieces: Bootloader — The software that manages the boot process of your computer. For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system.
Kernel — This is the one piece of the whole that is actually called? The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the lowest level of the OS. Init system — This is a sub-system that bootstraps the user space and is charged with controlling daemons. One of the most widely used init systems is systemd?
It is the init system that manages the boot process, once the initial booting is handed over from the bootloader i. Daemons — These are background services printing, sound, scheduling, etc.
Graphical server — This is the sub-system that displays the graphics on your monitor. It is commonly referred to as the X server or just X. Desktop environment — This is the piece that the users actually interact with.
Each desktop environment includes built-in applications such as file managers, configuration tools, web browsers, and games. Applications — Desktop environments do not offer the full array of apps.
One of the most popular things to do with virtual machines is to run different operating systems on one computer without needing to reboot. You can even back up copies of the entire virtualized guest operating system if you need to.
While using VirtualBox is a great way to try out one or more Linux distributions, there are some disadvantages. Virtualization comes with a performance hit due to overhead, though this is reduced if your CPU has virtualization support built-in. To take advantage of this technology, you also have to make sure that virtualization support is enabled on your motherboard in the UEFI or BIOS as well.
Depending on which Linux distribution and desktop environment you choose, your desktop environment and installed applications will vary—though most will cover your typical needs. Most Linux distributions ship with the Firefox web browser, for example.
Ubuntu Additionally, be sure to enable virtual desktops most modern Linux desktops have disabled them by default and give them a shot, too. Every desktop environment has a set of tools to help you customize the look and feel how you want it to. While some distributions are optimized for a particular desktop, nearly every major distribution gives you the option to install the desktop of your choice after the system is installed.
When you log in to the desktop, you can choose what desktop environment to run. If you ever get lost, there is plenty of help online. However, not all Linux installations use GNU components as a part of the operating system: Android , for example, uses a Linux kernel but relies very little on GNU tools.
You may have heard of Unix, which is an operating system developed in the s at Bell Labs by Ken Thompson, Dennis Ritchie, and others. Unix and Linux are similar in many ways, and in fact, Linux was originally created to be indistinguishable from Unix.
Both have similar tools for interfacing with the system, programming tools, filesystem layouts, and other key components. However, not all Unices are free and open source. Linux was created in by Linus Torvalds, a then-student at the University of Helsinki. Torvalds built Linux as a free and open source alternative to Minix, another Unix clone that was predominantly used in academic settings.
It's a common saying that the best Linux distro is the one that works best on your computer, so try a few to see which one best suits your hardware and your style of working. You can install Linux on your current computer be sure to back-up your data first , or you can buy a System76 or Purism computer with Linux already installed.
If you're not looking for the fastest computing experience possible, you can also install Linux on old computers, or buy a Raspberry Pi. Once you've installed Linux, read our article on how to install applications on Linux , and check back often for news and tutorials on all the best applications open source has to offer.
Its main benefits are —. It offers a free operating system. You do not have to shell hundreds of dollars to get the OS like Windows! Users, who are new to Linux, usually shun it by falsely considering it as a difficult and technical OS to operate but, to state the truth, in the last few years Linux operating systems have become a lot more user-friendly than their counterparts like Windows , so trying them is the best way to know whether Linux suits you or not.
There are thousands of Best Linux OSs and Linux softwares available based on the Linux Kernel; most of them offer state-of-the-art security and applications , all of it for free!
This is what Linux is all about, and now we will move on to how to install Linux and which Distribution you should choose. UNIX is called the mother of operating systems which laid out the foundation to Linux. Unix is designed mainly for mainframes and is in enterprises and universities. While Linux is fast becoming a household name for computer users, developers, and server environment.
You may have to pay for a Unix kernel while in Linux it is free. But, the commands used on both the operating systems are usually the same. Though they might seem different, at the core, they are essentially the same.
