4. What is ICT?
• Information – Data
• Communication – Transmitting and Receiving
• Technology – Mechanisms and Techniques
• So, ICT - The phenomenon of Data Transmitting
and Receiving with the help of specified
Mechanisms and Techniques. (This is my
explanation)

5. What is ICT? (contd.)
• What does the WIKI says ?
[https://en.wikipedia.org/wiki/Information_and_commun
ications_technology]
Information and communication technology (ICT) is an extended term for
information technology (IT) which stresses the role of unified communications
and the integration of telecommunications (telephone lines and wireless
signals), computers as well as necessary enterprise software, middleware,
storage, and audio-visual systems, which enable users to access, store,
transmit, and manipulate information
• Further the website says,
“However, ICT has no universal definition, as "the concepts, methods and
applications involved in ICT are constantly evolving on an almost daily basis"

6. What is ICT?(contd.)
Main aspects of ICT…
Again this is my point of view after evaluating
the ICT world.
1.People
2.Data
3.Data processing
4.Transmitting and Receiving

7. What is ICT? (contd.)
• This course is designed in a way that you will
get an overall idea what ICT is…
• There are many components and you need to
study and those components are well set in
order to start your journey with ICT

8. In order to achieve, Communication of Information, we need the
help of Hardware, Software and Human Interaction.
• Hardware – All physical items, equipment and
apparatus related to information processing
• Software – All programmed systems using
programming languages
• Human Interaction – People who are engaged
in Communication of Information.

10. History of Computers
Simple Animation

11. History of ICT (Past)

Charles Babbage's Analytic Engine is the first ever
computer (19th
Century)

First General Purpose Electronic Computer – ENIAC -
Electronic Numerical Integrator and Computer (1946)

Designed and Produced by: J. Presper Eckert and John
Mauchly

First General Purpose Commercial Computer - UNIVAC I
- (UNIVersal Automatic Computer I (1951)

12. Analytic Engine

13. ENIAC

14. UNIVAC

15. History of ICT (Past) – contd.
Generations:
1. First generation: 1937 – 1946 (Vacuum
Tubes)

First Electronic Digital Computer – 1937 by Dr. John V.
Atanasoff and Clifford Berry

First General Purpose Computer – 1946

Had Vacuum Tubes (nowadays we see ICs and Microchips)

16. 2. Second generation: 1947 – 1962 (Transistors)

Introduced Transistors instead of those large Vacuum Tubes
(nowadays we can't see transistors even)

ENIAC, UNIVAC came in.

Programming languages evolved from cryptic binary to assembly.

IBM produced computers to mark their leadership in the industry.
History of ICT (Past) – contd.

17. History of ICT (Past) – contd.
3. Third Generation: 1963 – 1971 (Integrated
Circuits)

Transistors were put into Silicon Chips called Semi Conductors.

Increased Speed & Efficiency.

Keyboards and Monitors were integrated via an Operating
System.

This generation is the beginning of the modern day computer!

18. History of ICT (Past) – contd.
4. Fourth Generation: 1972 – 2010
(Microprocessors)

Intel came into picture. Produced its first chip (Intel 4004)
which had all CPU, Memory, I/O Control in one single chip.
5. Fifth Generation: 2010 – Present (Artificial
Intelligence)

Today we are in this generation which has cloud computing, AI,
parallel processing, augmented reality and so on.

20. 
As you already know and as you are a part of the present state,
no need to mention the backbone of the contemporary state is
the WWW (or what we call as the Internet)

Everyone who involves with ICT (the ICT community) is
part and parcel of the Internet.

Cloud computing has become a huge boost. (According
to IBM, Cloud Computing means Computing as a Service
over the Internet (SaaS, PaaS, IaaS)
Present state of ICT
