===Understanding ICT – a brief history===
   −
Through the course of history, there have been discoveries and inventions that have changed social processes and structures greatly. The agricultural revolution and industrial revolution created the agrarian and industrial societies respectively. We are now in another such age, brought on by Information Communication Technologies (ICT). With information creation, access, processing and sharing becoming quicker and simpler, society is now being shaped these processes, so much so that, the term Information Society is used to describe society today. Participating in this society requires the development of new skills as well as an understanding of how these processes are affecting society. It is the responsibility of the education system to respond to this by helping students develop an understanding of ICT, its impact on society and the possibilities for learning through ICT. The education system also has to support the building of skills in students that will make them capable of functioning in, and be responsive to a society shaped by ICT.

Most of you student teachers must be using a cell phone to communicate, which even ten years ago would not have been the case with most students. A cell phone is a digital information and communication device, a part of the recent ICT revolution. Yet ICTs are perhaps nearly as old as humanity itself, as human beings needed to communicate with one another, beginning with symbolic (non verbal) ways, before language was invented. Language could be seen as first 'ICT', it   enabled (oral) communication amongst human beings. Yet oral communication had the limitation of space and time, meaning that the speaker and the listener had to be in the same space and time.

Script was the next ICT, invented around 5,000 years ago, which enabled information to be held distinct from   the   communicator   and   be   made   available   beyond   the   limitation   of   space   and   time   that   oral communication   imposed.     (You   would   be   learning   more   about   the   processes   of   speaking   and   listening (comprising   oral   communication)   and   reading   and   writing   (comprising   written   communication)   in   your courses on language learning. Writing also enabled easier recording of human history and thus the invention of script was a landmark in the history of ICTs.

Invention of printing technologies scaled up the 'writing' process and enabled mass production of books. The invention of radio and television created the 'mass media' in which simultaneously the same message could be transmitted to thousands of people. Each ICT invention enabled the processes of information creation, sharing, storing and communicating to be easier, quicker, more efficient (reaching more people) etc. Each invention was a significant event in the evolution of human communication processes and in the explosion in the availability of information.

ICT refers to those set of technologies that help us create information, access information, analyze information and communicate with one another. Human beings have always accessed information and communicated, but what makes these present technologies special is their digital nature.

We are now perhaps in the middle of the next epochal movement in the history of ICTs, the use of digital  methods of accessing, creating, modifying sharing, storing information as well as for communication. Most of you would have been born after the beginning of the mass use of cell phones (the second generation or 2G cell phone technology was available for mass use from 1991), towards the end of the first millennium, while many teacher educators would have been born before this period!

This phenomenon creates an interesting inversion in the school environment, in almost all other areas, the teacher (teacher­ educator) is more familiar than the learner (student­ teacher), while in case of ICTs (more specifically in the skill of using ICT devices and methods), it can often be the opposite! Research also suggests that younger people are quicker to pick up a technology than older people. ''Hence this course may require the student­ teacher to help the teacher educators to acquire some of the skills covered and support 'collaborative   learning   amongst   student­ teachers   and   teacher­ educators!  On the other hand,   the   experience   and insights of teacher educators can help student teachers to develop a critical perspective towards digital ICTs, which is essential, since digital ICTs have huge potential for doing good as well as harm.''

One point to note is that, one ICT does not replace the earlier ones, rather the earlier technologies tend to continue, to meet varying needs and contexts.

While technology for information creation, storage and processing has been developing continuously, one important development which changed the course of technology is the development of digital technologies in the electronic area. Whereas during the electromechanical area, information was stored largely stored in analog formats. During the electronic age, information was stored in analog and digital formats.

You will learn to use digital ICT for two purposes in the first year - 'connecting and learning' and 'creating (generic resources) and learning', in the two units respectively. Before 'connecting and learning' you need to have a basic familiarity with the ICT devices and tools.

Every computer must have an operating system (also called system software) to run other computer programmes. Even your mobile phone has an operating system. Operating systems start automatically when you turn on the computer, this process is termed booting. All the other computer programmes like programmes to paint, type, listen to music, learn maths etc., are called application software or 'Apps' which work with the system software.
 +
 +
Ubuntu is a ‘Free and Open Source Software’ (called FOSS in short) operating system. 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. Operating systems use a program called the Graphical User Interface (GUI, which is pronounced as goo-ee), to access other computer with a mouse. The popular operating systems are Microsoft Windows, GNU/Linux and Mac OSx. You will learn about the functions of an operating system, using an example of '''Ubuntu''' GNU/Linux operating system. With this learning, you can also operate a computer with Windows of Mac operating systems.

Ubuntu GNU/Linux (we will use Ubuntu hereafter) is a Free and Open Source Software (FOSS) Operating System. Ubuntu installation is quite simple, and can be done by an average computer user.
 +
 +
The minimum hardware required to install Ubuntu in a computer:
 +
# Minimum 40GB or above free space /  separate partition in Hard disk.
 +
# Minimum 2GB RAM (4GB and above preferred)
 +
# DVD reader or USB port.
 +
# Electric power should be available during the installation process.
 +
You will also need the Ubuntu software in a DVD or in a pen drive (as a boot-able USB device). In the computers in your lab, the Ubuntu GNU/Linux operating system along with educational software applications and utilities would have been installed. A copy of the same could be obtained from DSERT, if required. In case you need to install the system on the institution computers, or you would like to install in your own computer, you can do so. Being able to install the operating system itself on your computer is an empowering process. In many cases, if you face problems while using your computer, including serious issues such as hard disk crash, you can re-install the operating system to start using your computer again.
 +
 +
The installation process for the custom Ubuntu GNU/Linux system is available in this [https://teacher-network.in/OER/images/8/8e/Ubuntu_16.04_installation_as_stand_alone_OS.pdf document]
 +
 +
==== Basic functions ====
 +
# '''Logging in''': When you switch on your computer, you will see a login screen. Login with the user id (name) and password created by the system administrator. '''Ubuntu''' allows you to have a user interface in your own language, by specifying your language as the user language, during your user id creation. Once you have logged in, the home screen will appear.
 +
# '''Shutting down the computer-''' After you have finished your work, you have to turn off the computer. You must turn it off by clicking on the last button on the right hand top corner and select shut down. Never turn off the power button without shutting the computer properly.
    
==== Accessing and adding various FOSS applications, basic troubleshooting ====
 
==== Accessing and adding various FOSS applications, basic troubleshooting ====
 +
Ubuntu performs all the basic functions expected of an operating system, including the following:
 +
# It allows the user to login and logout and keeps the user data secure within that login
 +
# Users can browse the folders and files on the computer using a file browser
 +
# Users can use different applications on their computer for creating and accessing files. This includes accessing, creating, editing text, image, audio, video, animation files.
 +
# Users can connect to other devices - printers and scanners, mobile phones, pen drives, external hard disks and other storage devices, external DVD writers etc.
 +
# Users can connect to the internet.
 +
You can add more FOSS applications to your computer. Go to Applications > System Tools -> Software. You will need to type the required application name in the search bar. It will show all applications with the words you have entered and you will get an option for "Install". Click on "install" if you want to install the application. If your search does not get the application(s) you want, try with fewer letters / words to search . It may ask your Ubuntu log in password for authentication, just type your Ubuntu password press enter.
 +
 +
Your teacher will demonstrate these functions to you. Your teacher will also show you to connect to the internet.

The internet, a product of digital ICT, has changed the way we think of communicating. Talking to a friend through whatsapp or telegram chats, emailing or making a video call are just some of the ways in which the internet has changed the way we communicate with others. With the internet, you can connect to any computer in the world and access information. You can join other friends, form groups to learn about many things. Internet is also allowing new methods of learning through online courses and resource repositories. Unit 1 will help you learn how you can use ICT to connect and learn.

Downloading information and organizing
+
If you know the web address of the site you want to visit, you can type it in the address bar. Ex; http://kn.wikipedia.org. If you don’t know the particular web address, you can type the key word of searching object, e.g. wikipedia.  You can search not only for text, but also for images, videos using a search engine, such as DuckDuckGo or Google search engine. You can download the file (video, text file, image file) in to computer. Check if the copyright of the file allows to copy and use.
   −
Identifying license information and using downloaded information appropriately
+
You can save web pages offline to use without internet. To save the page, right click on the page and click on "Save Page As". In the save tab, you can give specific file name and in the file format you need to select "Web Page Complete" and then click SAVE. Now it will save html file with a thumbnail folder. By clicking on html file you can view web page offline.

Using safety tips while browsing
+
Using a search engine, your teacher will open [https://en.wikipedia.org/ Wikipedia]. She will explain how the search engine works and she will demonstrate different kinds of websites on the internet.
   −
You will develop a text document with a list of websites that you have accessed
+
