Technological innovation
Technological innovation is essential for human development.
From the printing press to the computer, people have devised tools for facilitating learning and communication.
Technology is not inherently good or bad, the outcome depends on how it is used.
Information and communications technology
Information and communications technology
(ICT) involves innovations in microelectronics,
computing (hardware and software), telecom-
munications and opto-electronics —micro-
processors,semiconductors, fibre optics.
These innovations enable the processing and storage of enormous amounts of information,along with rapid distribution of information through communication networks.
The role of ICT
It is accepted that telecommunication is a basic infrastructure necessary for economic and social development of a country.
This is even becoming more strong than ever as information related economic activities are growing.
Information and communications technology may be described as the support of the central nervous system of complex societies, transmitting and processing information and commands among the various parts of such societies.
Internet plays a fundamental function in ICT role
Rapid evolution of ICT
Predictions indicate the doubling of computing power every 18 –24 months and the doubling of communications power every 6 months. Both are accompanied by huge reductions in costs and massive increases in speed and quantity.
In 2001 more information can be sent over
a single cable in a second than in 1997 was sent
over the entire Internet in a month.
