What is Linux?

Linux is actually an operating system. It is in fact Unix like operating system. This is assembled under the model of free and open source software development and distribution. Well dear Linux was actually developed for personal computers. This was based on the Intel x86 architecture. But this has been since ported to more platforms than any other operating system.

Well guys and girls here that is in this very article you will get all the information regarding the Linux operating system. Now let me come on the point directly. Actually Linux has the largest installed base of all general purpose operating systems. This is because of the dominance of Android on smartphones. Also Linux is the leading operating system on servers as well as other big iron systems like that of mainframe computers. And this is used on 99.06% of the TOP 500 supercomputers. It is used by around 2.3% of desktop computers. The Chromebook that runs on Chrome OS, dominates the US k-12 education market and represents nearly 20% of the sub-$300 notebook sales in the US.

Some Important things about Linux

Henceforth guys and girls here you will get to know a lot of things about Linux operating system. There are a lot of things to be discussed here. So just have patience. Here I am going to write some essential things about Linux operating system . So just go through the following mentioned listed points.

• Linux also runs on embedded systems. This means to say that on those devices whose operating system is typically built into the firmware and is also highly tailored to the system.
• This also includes TiVo and also similar DVR devices, network routers, facility automation controls, televisions, smartwatches. Many smartphones and tablet computers run Android as well as other Linux derivatives.
• Also the development of Linux is one of the most prominent examples of free and open source software collaboration.
• Well Linux is packaged in a form known as Linux Distribution. This is not only for Desktop use but also for server use.
• There are quite a few mainstream Linux distributions like that of Arch Linux, Cent OS and so on and so forth. This also includes Debian, Fedora, Gentoo Linux.

This is what about Linux operating system in this section. If you are really interested to know about Linux operating system in details then you have to go to next sections. And these will be really very beneficial to you dear.

Design

Well dear readers here I will tell you about the design. So let me come on the point directly. The fact is that a Linux based system is a modular Unix like operating system. And this is associated with the deriving much of its basic design from principles established in Unix during the time of 1970s to 1980s. Thus such a system uses a monolithic kernel, the Linux kernel, which handles process control. This also includes networking, access to the peripherals and file systems. Separate projects that interface with the kernel provide functionality.

User Interface

Well dear here is the concept of user interface. First thing is that what actually user interface refers to? Well the thing is that the user interface also known as the shell is either a command line interface(CLI) or a graphical user interface or also it may through controls attached to the associated hardware. This is common for embedded systems. Also the thing is that for desktop systems, the default mode is usually a type of graphical user interface.

So guys and girls here is the most changed way in the arena of the user interface as compared to the other one. Several types of windows managers exist for X11, including tiling, dynamic, stacking and compositing. Well here is the concept of windows mangers. Actually what the term windows managers is. It is nothing but a type of mangers that provide the means to control. In other word Windows mangers gives the way for controlling the placement and appearance of individual application windows, and interact with the X windows system.

Video Input Infrastructure

Well now there is Video Input Infrastructure. In the above section I have discussed about the user interface. So if you want to know about the user interface then go to the above section. And here I am going to touch the concept of Video Input Infrastructure. Actually what video input infrastructure is. Pay heed.

Linux currently has two modern kernel userspace APIs to handle video input devices. They are following:-

• V4L2 API is for video streams and radio.
• DVB API is for digital TV reception.

Well because of the complexity as well as diversity of different devices, and also because of the quite a few formats as well as standards handled by those APIs.the very infrastructure needs to evolve to better fit other devices. Apart from this very thing a very descent userspace device library is the key of the success for having userspace applications to be able to work with all formats supported by those devices.

Uses

Well dear from the very now you have know come to know a lot of things about Linux. Now here is about uses. Beside the Linux distributions designed for general purpose use on desktops and servers, distributions may be specialized for various purposes. This include many things like that of computer architecture support, embedded systems, stability, security. localization to a specific region or language, targeting of specific user groups. Apart from these things, this also includes support for real time applications, or commitment to a given desktop environment.

Desktop

Well there are quite a few uses. Here I would like to discuss about desktop. The popularity of Linux on standard desktop computers and laptops has been increasing over the years. Most modern distributions include graphical user environment with two classy environments that are KDE Plasma Desktop and Xfce.

Servers, and supercomputers and mainframes

Linux distributions in fact have long been used as server OS. They have also risen to prominence in that area. Since 2010, Linux distributions represented 6 of the top 10, FreeBSD 2 of 10 and Microsoft 1 of 10.
