Technology and Society
What isTechnology
Technology is how people change the world around them.
People create technology to meet their needs and to solve problems.
The goal of technology is to improve the way people live.
The Six Areas of Technology
1. Communication2. Transportation3. Manufacturing 4. Energy and power5. Biological and chemical6. Construction
Technology changes over time.
Obsolete technology is one that is not longer used.
Example: Airplanes flying across the ocean in the 1950s had propeller and took about 12 hours. These technology is not longer in use. Newer airplanes use jet engines (current technology).
Technology as a System
A system is a group of parts that work together.
A technological system includes a goal, inputs, process, outputs, and, in some cases, feedback.
Parts of a System A goal is the purpose of the system. An input is something that is put into
the system in order to reach the goal. A process is the series of actions that
happens in the system. An output is a result or product. Feedback is information a system uses
to make sure the system meets the goal.
Technology’s Impact on Society
Technology has both good and bad impacts on society.

Risk-benefit analysis
Involves evaluation of possible problems compared to advantages.
Requires logical thinking and common sense.
Values and Trade-Offs
When values conflict, a decision involves trade-offs.
Trade-off: Exchanging one benefit for another.
