There are many operating systems such as Windows XP, Windows 7, Windows 8 and Mac OS X. Linux is also one of the well known operating systems which manage all the hardware resources that are connected with the desktop or laptop. In other words, it can be said that Linux OS manages the overall communication between the software and hardware, without the operating system the software could not function. The Operating System consists of the following essential ones.
The Boot loader is software that manages and controls the overall boot process of the computer. For most of the folks, this Boot loader is a splash screen that initially goes away to boot into the operating system. The Kernel is popularly known to be Linux and it is the core of the system which manages the CPU, memory and peripheral devices. It is considered to be the lowest level of the operating system. The Daemons are considered to be the background services which include printing, sound, scheduling etc that wither startup during the boot or after logging into the desktop.
The Shell is one of the Linux command lines that allow a person to control the computer through the commands typed into a text interface. At present with the aid of the modern desktop Linux, there is no any need to ever touch the command line. Graphical Server is a sub-system that displays the graphics on the monitor. It is denoted by just “X” or X Server. The Desktop Environment is a one where many of the folks interact with; there are many desktop environments such as Unity, GNOME, Cinnamon, Enlightenment, KDE, XFCE, etc. Generally, the desktop environment includes the built-in applications such as file managers, configuration tools, web browsers, and games etc.
The real fact is that the desktop environment does include any applications. Similar to that of the Windows and Mac, Linux offers a list of the high-quality software that can be easily installed without any issues. The modern Linux distributions include many App Store like tools that centralize and simplify the application installation.
In the Ubuntu Linux, the Ubuntu Software Center allows a person to quickly search among a list of applications and install them from the centralized location. The Ubuntu Software Center is a one that holds thousands of both free and commercial applications for the Linux.
Linux is an open source license; where the open source has the freedom to run the program for any purpose, how the program works and makes necessary choices as per your wish. The modified version copies can be distributed to others and at the same time, it can also be redistributed. One can install Linux on a series of computers without paying a cent for the software or the server licensing. It is said to be that Linux has evolved into the reliable computer ecosystems.
Linux has a list of different versions in order to suit nearly any type of user. Varying from the new users to the hardcore users a person can find a list subjected to that of the Linux in order to match the needs. These versions are known to be the distributions or the distros. Each and every distribution can be downloaded for free, burned onto the disk or USB thumb drive and installed at the same time as on many machines as a person prefers. There are many Linux distributions such as Ubuntu Linux, Linux Mint, and Arch Linux etc.
Each and every distribution has a different series of steps on the desktop. Some of them only suitable for the modern user interfaces such as Ubuntu Unity. On another side of the flip, the other set of the interfaces stick with the traditional desktop environment. One can also check for the several distributions on the concerned site. Some of the distributions such as Ubuntu Server and CentOS are free and some of them such as Red Hat Enterprise Linux and SUSE Enterprise Linux have an associated price. These ones include the support too.
The real fact is that Linux is one of the easiest installations of all the operating systems. Eventually, most of the versions of Linux offer a live distribution which means the operating system runs from either a CD/DVD or the USB flash drive without making any changes to the hard drive. Without any need for installation, full functionality can be received. Just click the Install icon and get through the simple installation wizard.
Initially, the installation wizards will be achieved through the following steps. First, make sure that the machine meets the requirements for the installation process. The queries will be also raised for the third party software such as a plug-in for MP# playback, video codec and more. The next step is the wireless setup if needed. If the laptop is used then it is necessary to connect to the network in order to download the third-party software and updates.
The next step is the hard drive allocation where a person is allowed to select how an operating system needed to be installed. If dual booting is needed then use the entire hard drive, upgrade an existing Linux installation or install over an existing version of Linux. Then select the type of installation, location, keyboard layout and User Setup. Once the system has completed the installation processes reboot it.
The core of Linux Operating system is Kernel where Shell is the command line translator, Command is the user’s instruction, Scripts are a collection of commands and Terminal is the command line interface. All these together constitute Linux OS.
Linux Kernel is under General Public License hence editing it is absolutely legal.
It is an OS that supports multiple users. A number of different tasks can be performed simultaneously using Linux OS.
Command [options] [arguments] is the exact syntax of Linux command.
Every Operating System definitely comprises some form of the virus in it. In comparison with all other operating system Linux is said to have the least number of viruses.
One of the basic difference is Linux OS is a free open source whereas the Unix OS is not completely free open source. Some categories of UNIX aren’t open source yet and they are contributed by big companies.
LFS stands for the Linux from Scratch where it explains about the inner workings of Linux by downloading, building and installing the packages.
I’m new to Linux. My friend suggested me to try this site. I’m really feeling lucky that I found such a wonderful site. They teach things from scratch which is easier to grasp even for a beginner with zero knowledge of Linux. Thank you, team, for your great service. Now, I’m able to work on my own in Linux platform.
One of the best sites anyone can refer to gain knowledge on Linux. Irrespective of your experience, beginner, intermediate or advanced, this website is much worthy to spend time with it. I have already worked a lot in Linux concepts but still, I follow this site. They come up with facts that are fresh to Linux every time I view the page.
Suddenly, I got stuck up with some issues in Linux. I surfed several sites to troubleshoot the problem by myself but wasn’t able to find the right answer for my query. As a last try, I tried this site. Thank God, it worked. The step by step guidance to repair the issues with Linux was very precise and simple for me try it out.
Currently, I’m learning Linux and working on a project. This site is my complete guide for the entire project. Whenever some problems arise the perfect solution is already available on the site. Now, I’m working on my project without any hiccups. During times I find some problem I feel it free to post questions at this site and get answers from experts in a short span of time.
I found some problems arising with Linux and couldn’t understand how to counterfeit it. Finally, I put myself in a dilemma whether to meet some professional service to get it recovered properly. But I ran out of time and had some important work process already going on. By chance, I met this site and worked step by step according to their suggestions. Success! I recovered it back myself, thank you, guys!
