|Ramulu was a farmer in a small village in a southern state. Agriculture was the main source of income from his 2 acre plot and he was growing vegetables and groundnuts. A few years ago he purchased a cell phone and enrolled his number in a [http://agritech.tnau.ac.in/success_stories/pdf/dmi/2014/dmi_ss1_2014.pdf market update service]. He started receiving daily price information on various agricultural commodities. This helped him manage how much he harvested, how much he took to the market and what prices he sold at.

To do these things, you use many ICT devices such as a mobile phone, a computer, camera. People may tell you about how they communicated or did things in the days before the phone.  It may be very hard for you to imagine but ICT (and all other technologies) were not always there - they were developed over time.   <br>

You may also have guessed one more thing - the different devices need to be connected. Internet, which you may have heard of, is a [[wikipedia:Computer_network|network]] of computers connected with one another.  Later in this unit, we will see how these these help in doing the various things above.

=Objectives=
 
−
In this unit you will be learning about:
 
−
#The nature of ICT - how technology has grown in society, how ICT has developed and how it has changed the way society is organized today
 
−
#How to use technology for self learning and collaborating with your friends
 
−
#The various things you can do with ICT (like writing, painting, singing)

The levels of the unit have been defined based on the ICT skills that we expect to build as well as the overall understanding and subject levels expected. You can imagine this somewhat like a spiral staircase where you learn some topic at a basic level, you move along to the next class and you can come back to discuss the same topic at a more advanced level.
+
===ICT have changed the society===
 +
Look around you - can you make a list of things that have digital technologies involved in them?  Yes, that is right.  Starting from the computer in your school, television, movies, videos and other materials for subject learning, mobile communication, [[wikipedia:Aadhaar|Aadhar]] card, land records, bank accounts, pension accounts and so many more things, ICT have become integrated into society in many ways.  
  
−
At each level you will be exploring different digital skills and you will also be required to create outputs that will explain your process of learning and demonstrate a particular digital skills.  Some of the outputs will be such that you can keep adding to it in each unit.
+
{{font color|purple|'''1. ICT can help create:'''}}
 +
ICT can create information in so many different ways - maps, audio, video, text, numeric data.  You no longer need to share your ideas only in text.  This means newer and newer methods of creation and sharing. You can also learn in different ways.  How you can learn learn and what is needed to be learnt have become different. For example, we no longer need to learn about a cash withdrawal slip, we need to know how to use the ATM.  Your teacher can now take a video of a class in your school and share it.  Different devices are getting developed; more and more functions are being performed by less number of devices.  For example, you can use the computer to watch a movie or play music. A smart phone can do many things a computer can do.

 +
The most important thing about ICT today is the internet.  The internet has changed the way we think of communicating with one another.  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 talk with others.  With the internet, you can also connect to any computer in the world and get information.  You can join other friends, form groups to learn about many things.

If so many things are impacted by ICT, it is important to understand how these work, and how they should be used [[ICT_student_textbook/What_students_need_to_know_about_ethics_of_technology|ethically and safely]]. ICT should be used in such a way that all can benefit. 
 +
 
 +
For example, take a resource like water or air.  Would you not want good quality water to be available to everyone?  Don't you want all students to be able to go to schools?  Don't you want good hospitals to be available to all?  Similarly, technology should be treated like a common resource of society, where everyone can access it, interact with it, benefit from it and contribute to it. More and more people should be able to use ICT according to their needs.  ICT should also be treated like a common resource or a public good - like public transport, public education or public health.

Introduction What is the nature of ICT Data representation and processing

What is this unit about

In the previous chapter, we saw how ICT are part of many things we do; and how they have changed the way we are working, learning and even playing. What is it about ICT that allows such changes to happen?

Let us consider the following pictures. Below each picture write 2-3 words describing what is happening in the picture.

  • Teachers in a video conference

  • Students learning how to shoot with a camera

  • Learning to read with a tablet

Think and write

Look at each of the pictures above and write 3 words that come to your mind in each picture

  • Students learning animation

  • Students learning with a simulation

  • Woman with a Cellphone

Think and write

Look at each of the pictures above and write 3 words that come to your mind in each picture

Ask your teacher or parent or other older members in your neighbourhood when was the first time they saw a computer or a phone or a TV.






In this unit, you will learn about what are ICT, how ICT developed and how we need to work with ICT for all of us to benefit. You can read more about how ICT developed in the chapter on Science, Technology and Society.

You may also have guessed one more thing - the different devices need to be connected. Internet, which you may have heard of, is a network of computers connected with one another. Later in this unit, we will see how these these help in doing the various things above.

Objectives

Interacting with ICT

  1. Understanding the nature of ICT - how technology has developed in society, how ICT have developed and how ICT have changed the society
  2. Understanding about the ICT environment - various devices and applications
  3. Understanding the safe use of ICT, including the internet
  4. Understanding the ethical and legal aspects of ICT

Communicating with ICT

  1. Understanding how to use technology for self learning
  2. Understanding how to use technology for connecting with each other for learning

Creating with ICT

  1. Understanding that you can do various things with ICT (like writing, painting, mapping, singing)
  2. Getting familiar with different applications for creating with ICT

ICT have changed the society

Look around you - can you make a list of things that have digital technologies involved in them? Yes, that is right. Starting from the computer in your school, television, movies, videos and other materials for subject learning, mobile communication, Aadhar card, land records, bank accounts, pension accounts and so many more things, ICT have become integrated into society in many ways.

1. ICT can help create: ICT can create information in so many different ways - maps, audio, video, text, numeric data. You no longer need to share your ideas only in text. This means newer and newer methods of creation and sharing. You can also learn in different ways. How you can learn learn and what is needed to be learnt have become different. For example, we no longer need to learn about a cash withdrawal slip, we need to know how to use the ATM. Your teacher can now take a video of a class in your school and share it. Different devices are getting developed; more and more functions are being performed by less number of devices. For example, you can use the computer to watch a movie or play music. A smart phone can do many things a computer can do.

2. ICT can help connect and communicate: The most important thing about ICT today is the internet. The internet has changed the way we think of communicating with one another. 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 talk with others. With the internet, you can also connect to any computer in the world and get information. You can join other friends, form groups to learn about many things.

Potter working, Bangalore India.jpg Potter and his work, Jaura, India.jpg Before digital ICT came, a potter could be gathering data about the mud, the water, the texture and he was making the pot. Now you have a photo of the pottery making and it is possible to know about the pot by looking a picture and reading about it. Is there any difference between what you know and what the potter knows?
  1. What are the ways in which ICT can help the potter create knowledge?
  2. What are the ways in which ICT can help the potter communicate?

If so many things are impacted by ICT, it is important to understand how these work, and how they should be used ethically and safely. ICT should be used in such a way that all can benefit.

For example, take a resource like water or air. Would you not want good quality water to be available to everyone? Don't you want all students to be able to go to schools? Don't you want good hospitals to be available to all? Similarly, technology should be treated like a common resource of society, where everyone can access it, interact with it, benefit from it and contribute to it. More and more people should be able to use ICT according to their needs. ICT should also be treated like a common resource or a public good - like public transport, public education or public health.

What is the internet

(This section contains some theoretical information about the internet; your teacher will discuss this with you. It is also possible to go to the activities directly and come back to this section after the activity).

Internet is a network of computers
 You may have, or you may have seen someone, look for some information using a computer or mobile phone. How is this possible? The internet makes this possible. The internet is nothing but a network of computers. Your computer may not have all the information you need. There may be other computers in different organizations, giving us different types of information. These computers are connected to one another, their network is called the Internet. The Internet is a physical network of millions of computers across the world. Each computer has a unique identifier. Some of these computers act as 'servers', they store data which can be accessed by other computers, hence the internet is like a huge library with information on almost any issue.
World Wide Web
 Initially the internet was a set of computers connected by one another and you had to send text messages for getting the information you need. This was difficult to do. In 1989, Sir Timothy Berners Lee developed an application called the "World Wide Web - www". Yes, the "www" is an application on the internet to access the internet in the form of a web pages, using an application called the Web Browser. Have you heard of the word browsing centre?

The web browser makes getting information from the internet easier. Computers transfer information through a method called Hyper Text Mark-up Language or HTML. Any information that we want to share - text, image or even audio and video - can all be shared by developing these web pages.

Different kinds of information could be made available and accessing the information also became easier.

Internet of things
 Now can you think of all the places the internet is being used? Write them below.

If you have accessed the internet, or if you know of anyone who has accessed the internet , can you list below 2-3 web sites?

Have you had any questions about or while using the internet?

How is the unit organized

In this unit, there are three levels of activities. Level 1 activities will introduce you to the unit and will be simple. Activities at the second and third level will be more advanced. This will be based on the ICT skills needed as well as the subject you are studying through that activity. At each level, you will learn ICT skills which would help you do a more advanced activity at the next level.

You can imagine this somewhat like a spiral staircase.

At each level you will be exploring new things about ICT; you will also be creating your outputs and building what is called a digital portfolio. This portfolio will include your outputs; from these you will be able to know what you have learnt. At the end of the year, your teacher will assess your portfolio.

You will also keep adding and changing your portfolio. How is that possible? When you make a model of clay or thermocol, you cannot change it after you make it. One of the special features of ICT is that you can change (edit) your creation. This means that, in Class 7 you can change what you completed in class 6 or in Class 8 you can change what you completed in class 7. This means you can keep adding to your knowledge and also improve the quality of your output. You will have a cumulative portfolio at the end of class 8.
