LINUX is an operating system or a kernel distributed under an open-source license. Its functionality list is quite like UNIX. The kernel is a program at the heart of the Linux operating system that takes care of fundamental stuff, like letting hardware communicate with software. Why do you need an OS? Every time you switch on your computer, you see a screen where you can perform different activities like write, browse the internet or watch a video.

What is it that makes the computer hardware work like that? How does the processor on your computer know that you are asking it to run a mp3 file? Well, it is the operating system or the kernel which does this work.

So, to work on your computer, you need an Operating System OS. In fact, you are using one as you read this on your computer. Who created Linux? Linux is an operating system or a kernel which germinated as an idea in the mind of young and bright Linus Torvalds when he was a computer science student. However, when his suggestions were rejected by the designers of UNIX, he thought of launching an OS which will be receptive to changes, modifications suggested by its users.

Click here if the video is not accessible. So Linus devised a Kernel named Linux in Something as you have a cone but no ice-cream on top. As time passed by, he collaborated with other programmers in places like MIT and applications for Linux started to appear. So arounda working Linux operating system with some applications was officially launched, and this was the start of one of the most loved and open-source OS options available today. The earlier versions of Linux OS were not so user-friendly as they were in use by computer programmers and Linus Torvalds never had it in mind to commercialize his product.

This definitely curbed the Linux's popularity as other commercially oriented Operating System Windows got famous. Nonetheless, the open-source aspect of the Linux operating system made it more robust. Linux gets its due attention The main advantage of Linux was that programmers were able to use the Linux Kernel to design their own custom operating systems. With time, a new range of user-friendly OS's stormed the computer world. Now, Linux is one of the most popular and widely used Kernel, and it is the backbone of popular operating systems like Debian, Knoppix, Ubuntu, and Fedora.

Nevertheless, the list does not end here as there are thousands of Best versions of Linux OS based on the Linux Kernel available which offer a variety of functions to the users.However, the course does assume familiarity with computers and common software, such as would be had from daily computer use.

Introduction to Linux

Its functionality list is quite similar to that of UNIX. It is responsible for all major activities of this operating system. It consists of various modules and it interacts directly with the underlying hardware. Kernel provides the required abstraction to hide low level hardware details to system or application programs. These libraries implement most of the functionalities of the operating system and do not requires kernel module's code access rights.

Kernel component code executes in a special privileged mode called kernel mode with full access to all resources of the computer. This code represents a single process, executes in single address space and do not require any context switch and hence is very efficient and fast. Kernel runs each processes and provides system services to processes, provides protected access to hardware to processes.

Support code which is not required to run in kernel mode is in System Library.

Operating System - Linux

User programs and other system programs works in User Mode which has no access to system hardware and kernel code. Linux kernel and application programs supports their installation on any kind of hardware platform.

Selecting the distribution that fits your needs and criteria is the first step on your journey into the world of Linux. Unlike with Windows and MacOS, there are quite literally thousands of different distributions from which to choose.

A linux distribution will take the Linux kernel and combine it with other software in order to create a complete, functioning operating system. The software added can vary greatly — web browsers, desktop environments, GNU core utilities, and much more.In this topic, we are going to discuss the Some basic introduction of Linux with the following concepts.

But now we have a curiosity, how all these activities are supported by the electronic devices? How the processor of our device help us with the activities to be performed? It is the operating system which helps us to interact with the hardware. Operating System OS is what we need to work on our electronic device. As you are reading this on your electronic device you are utilizing the benefits of OS.

Operating system is a software that leverages hardware of the devices such as the laptop, desktop or tabs to the most. In a simple way, we can say the operating system is a bridge between the software and the hardware.

Without OS it is not possible to run or execute software or program.
