1. Aphorisms on
Information, Technology & Systems
Prasad Chitta
Techno Functional Consultant
thanking GOD who is the source, medium, receiver and the purpose of
information!

2. Information:
1. That is expressed, that flows, that is to
inform; is Information.
– The source entity expresses its
attributes, ideas, emotions in a stream like flow
– There is a medium that carries the flow from the
source to the intended and interested parties
– It is perceived by the receiver and receiver is
informed with a new fact

3. Information:
2. For ease of expression and transmission by
sensors, it is encoded.
– The source expresses itself by the means of
sound, touch, size & shape, smell and taste
– There is an encoding scheme by which each type
of stream flows through space, air, light &
heat, liquid and solid media
– The receiver’s sensors capture and assemble the
whole expression as a whole from multiple
encoded streams!

4. Information:
3. The state of the System is altered in some way
as the information flows (i.e., is consumed.)
– The purpose of information is to impress the ‘receiver
subsystem’ in some way by the ‘source subsystem’.
– The information changes the way the overall
environment behaves or acts creating an event.
– Events trigger further information to flow and the
system continues through state changes both
gradually and spontaneously.

5. Information:
4. The System reaches a perfect equilibrium
when the information flow is “just right”
– The provider subsystem provides accurate and
timely information to the consumer subsystem to
function smoothly without needing to generate
additional events in the system environment.
– The –ve expression for the same is “system dies
when the entropy is at the maximum”
• Entropy is the amount of unusable information that
hinders the flow….

6. Technology:
5. Application of technique to achieve optimal
information flow is Information Technology.
– A process of studying and achieving ease in
accomplishing a task is the technique
– Applying technique to optimize a sequence of
tasks is the purpose of technology.

7. Technology:
6. Techniques are needed to efficiently
encode, secure, transmit, store, retrieve, dec
ode the messages of an information stream.
– The encoded message segments are called data
– The process of encoding and storing data gives an
opportunity to manipulate & process data to
derive new inferences thereby generating new
insights of the information flow – different
perspective of the state of the system….

8. Systems:
7. Information Systems are purpose built
configurations of electronic devices to tap on
to streams of information for the purpose of
processing data.
– Open systems that “consume information from”
and “produce information into” the higher level
complex system.
– Each information system built for a set of data
processing needs.

9. Systems:
8. This Universe is a closed complex system
comprising of open systems as its components.
– Constituted by innumerable galaxies, stars, solar
systems, planets, layers of
atmosphere, ecosystems, biomes, habitats, cultural
systems, political systems, businesses, humans, living
cells, atoms, fundamental particles, spectrum of
energies….
– Cyclically evolving, sustaining and dissolving
exchanging flows of information AND energy &
matter

10. Conclusion:
Technology
Information
Celebrating 8888 days of my association with Information Technology
and a 1000 weeks of work experience in
optimizing information flows and processing of data across the systems on this
tiny spaceship called Earth with its 7 billion human travelers!
