The Adventof the

Information Society

The Information Society

John Naisbitt, “the Megatrends” - 1984 introduces the “

INFORMATION SOCIETY” concept.

A society in which a majority of workers are involved in the transmittal of information

Time Magazine - 1982 Names the computer “

Machine of Year” – signified the computer’s “coming of age”.

What is a Computer?

A computer is an electronic device which accepts data, processes the data, stores and produces the result as information under the direction of a stored program of instructions with speed and accuracy.

What are ICTs ?

ICTs stand for information and communication technologies

These technologies include computers, the Internet, broadcasting

technologies (radio and television), and telephony

diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage informationInternet

The ICT Revolution

Technological advancement have revolutionized

communication and spread of information

Landmarks In 1875, for example, the invention

of the telephone breached distance through sound.

Between 1910 and 1920, the first AM radio stations began to broadcast sound.

By the 1940s television was broadcasting both sound and visuals

The ICT Revolution …

Landmarks … In 1943, the world’s first electronic

computer was created. Microprocessor invented in the 1970s

and computers became accessible to the public.

In the 1990s, the Internet migrated from universities and research institutions to corporate headquarters and homes.

The Digital Revolution.

Earlier technologies relied on Analog transmission ( incorporated a combination of light and sound waves to transmit messages

Alexander Graham Bell invented of the telephone in 1875 used analog transmission

In the late 1940s, an alternative to analog transmission of voice the pulse-code modulation (an encoded signal of pulses) marked the start of digitization in telecommunications

The Digital Revolution …

1961 that the first digital carrier system was installed in U.S Digitization meant the widespread

replacement of telephone operators with digital switches.

In 1971 the first fiber optic cables suitable for communications made - leading to efforts to send communications signals via light waves. (Light wave transmission systems are inherently digital.)

The Digital Revolution …

By about 1989, “ones and zeros” had become the language of telephone networks in the US

Today, voice is translated into data packets, sent over networks to remote locations, sometimes thousands of kilometers away, and, upon receipt, translated back to voice.

Consequences of Digital and ICT Revolutions

On a societal level, the digital and ICT revolutions make possible better and cheaper access to knowledge and information. This speeds up transactions and processes and reduces their cost, which in turn benefit citizens and consumers.

The ability of ICTs to traverse time and distance allows human beings to interact with each other in new ways. Distance is no longer a consideration.

Consequences of Digital and ICT revolutions …

Emerging Information Economy An information economy is where the

productivity and competitiveness of units or agents in the economy (be they firms, regions or nations) depend mainly on their capacity to generate, process, and apply efficiently knowledge-based information

Pervasive use of information and communications technology has made information plentiful in this economy.

Features of the information economy

The information economy is global. has the capacity to work as a unit in real time on a

planetary scale Corporations and firms now have a worldwide base

for skilled labor to tap it is highly productive profits come from speed of innovation and the

ability to attract and keep customers

Information economy is the same as “knowledge economy”, the “new economy”, or the “network economy”

Technology/Computer Literacy – Why Is It Necessary in the Information Age?

ICT Literacy ..

Computers are everywhere Businesses Government Education

We live in Global Village We are part of the Information

network Technology for students is about

economic competitiveness
