=Science and technology=

Many times you hear the word science and technology together. What is the connection between the two? Do you know? Study of science includes a method of observing things around us, thinking about why those events happen, explaining why the events happen, recording information about the events and also predicting what might happen. Often, scientists imagine what might be the solution and what might be the answer to the puzzles around us. The understanding of phenomena can lead to the development of tools – this is  what we call technology. The technology can provide us more methods of observing, experimenting and recording.  And this in turn results in the advancement of science.  Thus, science and technology share a symbiotic relationship.

When you tried to explore the questions in the previous section, you may have come across words like satellites, signals, transmission, receiver, radio waves, etc. All of these words refer to the various technologies that are used for communication. Can you think of all the things that we use for communication?

 

Information is not new for human beings; communication has been known since the time human beings lived in caves.  Thus ICT are as old as human beings themselves; human beings needed to communicate with one another, beginning with symbolic (non verbal) ways, before language was invented. The language we speak could be seen as first 'ICT', it  enabled (oral) communication amongst human beings. Writing and script was the next technological advancement - around 5000 years ago - which enabled information could be created and communicated at different times and in a different place.  Oral communication does not have this benefit,  Writing also enabled easier recording of human history and thus the invention of script was a landmark in the history of ICTs.  Next came printing which made it possible replicate writing.  The invention of radio and television was the next advancement in ICT as it became possible for more and more people to access information.  Thus, the technology for information creation and communication has been changing, connected with the advancements in scientific knowledge.  When you tried to explore the questions in the previous section, you may have come across words like satellites, signals, transmission, receiver, radio waves, etc. All of these words refer to the various technologies that are used for communication.
