Foundations of Technology
Troubleshooting is a form of problem solving that is used to help repair systems.
The technological ages of technology are time periods in which technological advancements were made.
Paleolithic Age (Old Stone Age): 500,000 BC.
Mesolithic Age (Middle Stone Age): 10,000 BC.
Neolithic Age (New Stone Age): 4,000 BC.
Bronze Age: 2,300 BC. Architectural period that included combining tin and copper to produce bronze.
Iron Age: 700 BC. Period marked by the first use of iron and steel.
Middle Ages: 450 AD. Architectural period after the Roman Empire. Divided into the early, high, and late middle ages
Renaissance: 1,400 AD. Architectural period marked by the revival of classical influence and the sharing of ideas.
Industrial Age: 1,750 AD. Period marked by the first use of complex machinery, factories and urbanization.
Information Age: 1,950 AD to present. Period marked by the sharing, gathering, manipulation, and retrieval of information.
Prototypes and Mock-ups
Prototypes are required to function and look as the final product would, while a mock-up just has to look like the final product. The top picture represents a mock-up of a car, and below it would be the prototype.
Core Technologies are the building blocks of technology systems.
The major core technologies include:
Mechanical: uses mechanical parts to crate a system (ex: car or pulley system)
Structural: structures that support something else (ex: bridges)
Electric: the technology of generating electricity (ex: power plants)
Electronic: using small amounts of electricity for controlling (ex: lamp, cell phones)
Thermal: using or generating heat for power (ex: car engine)
Materials: the technology of combining materials (ex: combining copper and tin to make bronze)
Fluid: using liquids or gas to power a system (ex: hydroelectric power plants
Optical: using light to generate power (ex: solar panels)
Biotechnology: changing the genetic makeup of plants or organisms (ex: genetically altered plants)
Sub-systems are systems within a larger system. Examples would include the engine inside of a car, individual stores within a mall, camera system within a smartphone, etc.
Research and Development
Research and Development involves gathering information to help with the innovation or development of a product.
Batch Process of Manufacturing
Making products in a large quantity, for example printing images on t-shirts in large amounts.
Input, Output, Process, and Feedback
Input: putting information into a system
Output: the end result of the system
Process: how the system reacts to the input
Feedback: reaction to the feedback
Open and Closed Systems
Things can interact with open systems, but cannot with a closed system. An example of an open system is a living organism, because organisms require interaction with their environment (eating/drinking, sunlight, social interactions, etc.) in order to function properly. An example of a closed system would be a microwave because while the system is functioning nothing outside of the microwave affects it.
