__FORCETOC__
=Introduction=
Ubuntu is a [https://en.wikipedia.org/wiki/Free_and_open-source_software ‘Free and Open Source Software’] (called FOSS in short) [https://en.wikipedia.org/wiki/Operating_system Operating System]. You may be familiar with Microsoft Windows operating system or used an application called Adobe Reader. Windows or Adobe Photoshop are ‘proprietary’ , meaning they cannot be copied or shared or modified by us; FOSS applications are licensed under the ‘General Public License’ which allows all of us to share the software freely, we can also modify the software as per our needs. Hence it is important to use FOSS in our schools. Teachers must learn and teach FOSS and avoid use of proprietary software, since it is not possible for all to access and use proprietary software, and not possible for anyone (other than the vendor) to study or improve the software.
Since all the software like Office suite, web browser, educational software can be bundled with Ubuntu GNU/Linux operating system, all these applications can be installed on the computer at one time. On proprietary software Windows, each software has to be separately installed, which can make it cumbersome and time consuming.
==Ubuntu versions detail ==
Ubuntu releases new versions every six months, and always supports them for at least 18 months with daily security fixes and patches to critical bugs. Some releases are designated as Long Term Support (LTS) versions, which have three years support for the desktop and five years for the server editions. It is intended that new LTS versions will be released every two years.
* The most recent standard version, Ubuntu 17.04, was released on April, 2017.
* The most recent LTS version, Ubuntu 16.04 (Wily Werewolf), was released on April 21, 2016
* The next version of Ubuntu, Ubuntu 17.10, will released in October 2017.

==Installing Ubuntu alongside the Microsoft Windows Operating System==
You may have bought a new computer with Windows pre-installed, or you may want to install Ubuntu on your existing computer, which already has Windows on it. Steps for the 'side-by-side' installation are available in this [https://drive.google.com/file/d/0BwTV-oNEYKZBVV81NWRPOGdpcEE/view document]
== Using Ubuntu through 'Virtual Machine' option ==
[https://www.virtualbox.org/ VirtualBox] allows you to run the Ubuntu operating system inside another operating system like Windows.In this method also, your existing Windows system will not be affected. Virtual machine require a good hardware configuration to run smoothly, at least 4GB RAM, 50 GB free space and strong processor.
Follow these steps to install Ubuntu in 'Virtual Machine'.
# Open VirtualBox wizard on your computer
# Select 'New' and a new window will open.
# Give a name for your setup, you could use 'Ubuntu'.
# Set your Memory (RAM) (minimum 2GB)
# Click next to get virtual machine storage size window. Put the hard disk space you need for Ubuntu (minimum 35 GB) and complete the steps suggested by wizard after clicking the create button.
# On VirtualBox main window, select start and select your Ubuntu media source (pen drive or DVD drive where you have the Ubuntu software).

#Remove your installation media from the virtual optical disk drive before restarting the Virtual Machine.
== Using Ubuntu without installation ==
You may be unable to install Ubuntu on your computer, or you may be using a computer belonging to your institution*, which may not allow you to install Ubuntu. In such a case, you could use still Ubuntu, by connecting your computer to a Ubuntu bootable pen drive or Ubuntu DVD to your computer and using the 'Live' option.
In this method your existing Windows operating system is unaffected. You can use all the installed applications in Ubuntu, but generally these may run slower than if had installed Ubuntu, because of the lower read/write speed in USB sticks or DVD drive. Secondly, in the 'Live' mode, you can not save any working document in the hard disk of your computer. <br>
The method to use live mode is given below:
# Connect your Ubuntu pen drive or DVD
# Restart your computer
# Go to Boot menu and select your bootable device and press Enter.
# In next screen, select 'Live system' option.
# Your system will use Ubuntu system, in the 'Live' mode, without installing it.
# You can close the 'Live' session, by removing the bootable device after shutting down your computer
(*Of course, you should discuss with your institution, the benefits of using FOSS tools and platforms and encourage and persuade them to be open to allowing staff to installing FOSS tools on their systems. Such installation can be done alongside other applications on the computers, so there is no flip side to this. Many institutions across the world have switched completely to FOSS operating systems and applications, and you should persuade your institution as well.)
