Linux is the best-known and most-used open source operating system. Just like Windows XP, Windows 7, Windows 10, and Mac OS X, Linux is also an operating system. An operating system is a software that manages all of the hardware resources associated with your desktop or laptop. To put it simply – the operating system manages the communication between your software and your hardware. As an operating system, Linux is system software that sits underneath all of the other software on a computer.
Linux is packaged in a form known as a Linux distribution (or distro for short) for both desktop and server use. The defining component of a Linux distribution is the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux was originally developed for personal computers based on the Intel x86-architecture, but has since been ported to more platforms than any other operating system. Because of the dominance of the Linux kernel-based Android OS on Smartphone’s, Linux has the largest installed base of all general-purpose operating systems. Linux is also the leading operating system on servers and other big iron systems such as mainframe computers, and the only OS used on TOP500 supercomputers.
Linux was one of the first open-source technologies, but many programmers have contributed and added software that’s completely open-source for any user. This means that you can download the source code and change it any way you like. Some developers have restrictions on how you can distribute the code. For instance, some developers allow you to change the code, but you cannot distribute it for money.
In comparison to Windows, Linux has more advantages like provides its own source code through which we can customize the whole operating system in our own flavor, highly secured – rarely infected by viruses, spywares, malwares etc., having better community support, needs very minimum requirement to operate, highly reliable etc.
Linux has a number of different versions to suit nearly any type of user & almost every purpose like smart devices, education, Gaming, Science & research etc. From new users to hard-core users, we’ll find a “flavor” of Linux to match our needs. Nearly every distribution of Linux can be downloaded for free, burned onto disk (or USB thumb drive), and installed (on as many machines as you like). The Linux distributions like Ubuntu, Cent OS, Fedora etc., nowadays, are the most popular operating systems which is installed & used on various platforms with different utilities and functions.
