Internet as a ICT tools
What is ICT?
 During last decade of twentieth century there was extraordinary development in
information and communication technology (ICT) which led to a transmutation of
processes and practices in almost all aspects of human activities.
 Information and communication technologies (ICTs) are the technologies used in
the conveying, manipulation and storage of data by electronic means.
9
Information and Communication Technologies
 Information is data that has been sorted and arranged.
 It consists of organized facts and opinions people receive during daily life.
 Changing data into information is called data processing or information processing.
 It involves gathering, organizing, and reporting data so it is useful to people.
 It is often done using information technology.
ICT Tools
 Radio, television, video, DVD, telephone (fixed line & mobile), satellite systems,
computer and network hardware and software; (equipment and services associated
with these technologies, such as videoconferencing and electronic mail.) , blogs
11
Blackboard
OHP,
Phone,
Pager
TV/VHS,
Wireless Phone
LCD, PC
Whiteboard,
Interactive
Panel
Forums
Search
Engine,
Blogs,
e-Groups
Information and Communication Technologies
 People often use the terms information and communication together.
 These terms are related, but each means something different.
 Two words we need to know to understand communication technology are data and
information.
 Data includes individual facts, statistics (numerical data), and ideas.
 These facts and ideas are not sorted or arranged in any manner.
What is Communication?
 Communication is simply the act of transferring
information from one place to another.
 Exchanging Information from computer to another
computer
 The classic communication system is made up
of an information source, an encoder, a transmitter, a
receiver, a decoder, storage, retrieval, and an
information destination.

Synchronous Communication
• Online Chat
– Text based
– Audio based
– Video based
• Mobile Technology
– Conferencing
– Phone
• Satellite
– Television channel
– Video Conferencing
14
Asynchronous Communication
 Discussion Forums
 Blogs
 e-Groups
 Wikepedia (Knowledge base)
 Google (search engine)
 Mobile SMS, MMS & Podcasting
15
Scope of Internet as a ICT
• Education
• Research
• Communication
• Leisure and Entertainment
• Exploring the world
• Finance
• Shopping
• And many more ….
16
Scope of Internet as a ICT in Education
 ICT as a tool to innovate teaching-learning practice via Internet
(i.e. digital content, multimedia, teaching-learning methods,
learning environment)
 ICT as an administrative tool (i.e. education management
information systems (EMIS)
 ICT as an expanding learning opportunity (i.e. distance learning, e-
Learning)
 ICT as a facilitator of higher-order thinking skills (i.e. learner-
centered, self-directed learning, tailored learning)

Traditional v/s Internet based ICT education
Approach

 Physical – limited size
 Synchronous
 Unlimited
 Anytime, anywhere
 PowerPoint / transparency /
etc
 Textbooks / library
 Video
 Multimedia / simulation
 Digital library
 On demand
 Syn & Asyn. Communication
 One learning path  Learning path and pace
determined by learner
Psychology of using Teaching Aids which include
ICTs
 Hear is an effective saying
 I hear, I forget : Verbal description only are not enough for learners
to remember and understand. Visualization of objects especially in
science and technology is important
 I see, I remember: Knowledge that is gained through the site is more
colorful, accurate and permanent. It is said that 80% of our
knowledge is gained through our eyes.
ICT can help learning
 Develop understanding
 Speed and automatic functions of ICT can enable teachers to demonstrate,
explore or explain aspects of their teaching, and students learning, more
effectively e.g. use of a spread sheet to perform calculations in order that
patterns can be concentrated on rather than the calculating.
ICT can help learning
 Extend access to sources
 the capacity and range of ICT can enable teachers and students to gain access
to historical, recent or immediate information, through, for example,
accessing information on CD-ROM or the Internet
 Enhance enquiry skills
 search for and compare information from different sources
ICT can help learning
 Enhance the communication of ideas
 communicate with other people, locally and over distances, easily and
effectively
 present information in ways which are accessible in different forms for
different audiences.
Does ICT increase access to learning opportunity?
 Education opportunities in dispersed locations where conventional schools are
not viable;
 A choice to students and parents of what they want to learn i.e. Choice based
credit system (CBCS);
 A safety net for school drop-outs so they do not lapse into illiteracy;
 Alternative venue to schools.
 Second chance education.
 Standardised curriculum materials
 Lifelong learning concept
 Limiting fraud in assessment process
23
Internet based ICT in Agriculture using web
applications
 There are many web sites available for getting information regarding
agricultural products.
 One of them is “Soil Health Card” a 12th National e-governance award winner.
It reflects soil testing report (Current composition of soil) and provides
information about which crops farmers should cultivate and which manure
should be applied in what proportion.

Green ICT
Green ICT refers to an approach in reducing the energy and other resources
consumed and the emissions and other waste produced across the ICT lifecycle –
from manufacture, procurement and use of ICT in an organisation to its re-use and
aims to improve environmental sustainability of organisations. Specifically, Green
ICT as applied to the use of ICT resources aims to:
 Reduce energy consumption and CO2 emissions during ICT use
 -Reduce environmental impact of disposal of ICT waste products
In addition to the above, Green ICT also explores how ICT applications can be used to
help other sectors conserve and optimise energy usage.
25
Steps towards Green ICT
 Reducing Power Consumption of ICT equipments.
 Going Paperless
 Buying Energy-efficient ICT equipments
 Disposal, Re-use and Recycling ICT Equipments
 Server Optimisation and Virtualisation
 Indirect ICT Savings
– Tele Conferencing
– Web Conferencing
– Video Conferencing
26
Our Commitment
Accelerating Our Daily life activities by
Convergence of Technologies & Sharing of
Experiences and Resources.
Green ICT can reduce costs and the
negative impact
on the environment, making being
green good for all businesses
27
