This article is all about Linux operating system. In this article, we learn about basic facts about Linux operating system. Linux is an open source, unlike windows. Linux operating system is used in personal computers, servers supercomputers, smartphones, and many other appliances because Linux is the totally transparent operating system in comparison with windows operating system. Linux is originally developed for personal computers which are based on intel ×86 architecture. Now Linux has the largest installed base of all general-purpose operating systems. Because of the dominance of Android on smartphones. Linux is mainly used on servers and supercomputers as an operating system but it is only approx 2% of desktop computers except for chrome OS which is used in Chromebooks.
Firstly Linux is used in supercomputing community in the mid-1990s, where organizations such as NASA started to replace their expensive machines with inexpensive commodity computers running on Linux operating system.
How Linux was created
Linux was created on the base of Unix. Much of its basic design is derive from principles establishing in Unix during the 90th century approx in the 1970s to 1980.It is completely just like Unix. Linux has very fewer issues in it. The basic difference in between Linux and Unix is, Linux is a completely freeware and Unix is not a freeware. The principle author of Linux is Linus Torvalds. The Unix operating system was firstly implemented in 1969 at Bell Laboratories in united states by Thompson, Dennise Ritchie, Douglas McIlroy and Joe Ossanna. Firstly Unix is written in assembly language, as was common practice at the time. Later in 1973, it was rewritten in the C programming language by Dennis Ritchie.
Types of operating systems present in market
As being a freeware and having open source license it is easily available online for free. To install Linux operating system on your desktop easily download it from the internet and burn it to a CD or it to a flash drive and then install it on your system. Linux has many versions for the different purpose and uses. Typically, Linux is packaged in a form known as a Linux distribution for both desktop and server use. Some of the most popular mainstream Linux distributions are Arch Linux, CentOS, Debian, Fedora, Gentoo Linux, Linux Mint, Mageia, openSUSE, Backtrack, and Ubuntu, together with commercial distributions such as Red Hat Enterprise Linux and SUSE Linux Enterprise server.
Uses of Linux operating system and working of Linux operating system
Linux has two user interfaces in it, the user interface is also known as the shell. There are two user interfaces in Linux operating system is either a command-line interface (CLI), a graphical user interface (GUI). For desktop systems, the default mode is usually a graphical user interface, although the CLI is available through terminal emulator windows or on a separate virtual console.
CLI is a text-based user interface, which uses text for both output and input. Generally, On the desktop systems, the most popular user interfaces are the GUI shells. Most popular user interfaces are based on the X Window system, often simply called “X”.
A distribution is largely driven by its developer and user communities. In many cities and regions in nowadays, local associations are known as Linux user Groups (LUGs) seek to promote their preferred distribution and by extension free software. They hold meetings and provide free demonstrations, training, technical support and operating system installation to new users. Many internet communities also provide support to Linux users and developers to largely drive Linux distributions all over the world.
Linux is granular. That means that we have the almost infinite amount of control over the system. In windows, you only can control what Microsoft allows you to control. In Linux operating system, everything can be controlled by the terminal in the most minuscule to the most macro level.
Linux distributions support dozens of programming languages. Many programming languages that support Linux for example PHP, Perl, Ruby, Python, Java, Go, Rust and Haskell. First released in 2003, the LLVM project provides an alternative cross-platform open-source compiler for many languages.
Uses of Linux operating systems and applications of Linux operating system
Linux is commonly used in these following places and appliances
5. Smart devices like mobile phones
6. Embedded devices like xola android phones
8.Specialized uses like
- Home theater PC
- Digital security
- System Rescue
Now all the basic concepts and facts related to the Linux are described in above post If you have any other suggestions and queries simply comment below and solved out these queries. In next article, we will learn about how to install Linux in virtual box and VMware software and also learn about how to use Virtualbox and VMware workstation.
