Learn Ubuntu

Introduction

ICT Competency

Operating systems use a program called the Graphical User Interface (GUI, which is pronounced as goo-ee). It allows you to access other computer programmes (applications) by using a mouse. The popular operating systems are Microsoft Windows, GNU/Linux and Mac OSx. In this section, you will learn about the functions of an operating system, using an example of Ubuntu GNU/Linux operating system. With this learning, you can operate a computer with Windows of Mac operating systems

Educational application and relevance

Ubuntu is a ‘Free and Open Source Software’ (called FOSS in short). While software applications like Microsoft 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.
Since all the software like Office, web browser, educational software can be bundled with Ubuntu GNU/Linux operating system, so all applications can be installed on the computer at one time. On proprietary software Windows, each software has to be separately installed, which makes it cumbersome and complicated.
There are a large number of freely shareable educational tools on GNU/Linux, pertaining to mathematics, science, social sciences etc which can be used in all schools.
There are large number of additional tools on GNU/Linux freely shareable, such as IBUS which supports word processing in more than 50 languages, including all languages used in Karnataka such as Telugu, Assamese, Tamil, Urdu, Marathi, Hindi etc. or the ORCA screen reader necessary for the visually handicapped or Scribus for desktop publishing.

Version

In once in a six months, Ubuntu is releasing new version of the ubuntu. The first Ubuntu release coincided with the release of Ubuntu 4.10 which was codenamed "Warty Warthog". The recently released version of Ubuntu is 16.10 (as December 2016), but Ubuntu 16.04 is the latest LTS(Long Term Support) version. The LTS designation applies only to specific subsets of the Ubuntu archive. The LTS may not apply to all flavors and remixes of Ubuntu. For example, for 8.04 LTS, Kubuntu chose to move to KDE 4.0 and didn't issue an LTS release. In 10.04, the Netbook Edition was not an LTS. The project will decide which flavors will be LTS and the support duration for each, early in the LTS development cycle. Ubuntu changed to be available as a full system DVD instead of an Add-on CD.[6] Ubuntu is also installable[7] via a selection of "Ubuntu" packages for all distributions using the official Ubuntu repositories (Ubuntu and Kubuntu mainly).

Configuration

Processor: 2 GHz dual core processor or better
Memory: 1GB of RAM (2GB recommended)
Disk: 30GB of disk space depending on options
Graphics: If you plan to use the netbook interface, you will require a graphics card that supports 3D acceleration on Ubuntu. Most netbooks are supported very well and shouldn't be problematic.
Either a DVD drive or a USB port for the installer media.

If your computer is not matching any of the above hardware specifications, and you are is old computer, install Lubuntu OS. Lubuntu is Ubuntu based distribution and it is meant for low hardware configuration computers.Lubuntu is a fast and lightweight operating system. It has very low hardware requirements Download Lubuntu ISO 32bit from here and 64bit here.

Overview of Features

Ubuntu is the Linux Terminal Server Project and many applications relevant to education including GCompris, KDE Edutainment Suite, Sabayon Profile Manager, Pessulus Lockdown Editor, Ubuntu Menueditor, LibreOffice, Gnome Nanny and iTalc. Ubuntu CDs were previously available free of charge through their Shipit service; since version 8.10 (2008) it is only available as a download in a DVD format.

Edubuntu's default GUI is Unity while GNOME is still available.[1] Unity has been the default GUI since the release of 12.04. Since release 7.10, KDE is also available as Ubuntu KDE. In 2010 Ubuntu and the Qimo 4 Kids project were working on providing Qimo within Ubuntu,[2] but this was not done as it would not have fitted on a CD.

Other similar applications

In reality, hundreds of Linux distros are in daily use; DistroWatch.com features a top 100 list of the current most-downloaded distros, where Mint, Debian, Ubuntu, openSUSE, and Fedora hold the top 5 spots. Now, if you're new to Linux, Ubuntu is a very good place to start off.
