Resources for technology
All technological (human) activities require what?
resources, which are the things needed to get a job done.
WHAT IS A SYSTEM?
A system is a group of interrelated
components designed collectively
to achieve a desired goal. Systems
can be open-loop or closed-loop.
What IS criteria?
Rules
What IS system?
A system is an arrangement (pattern, design) of parts which interact with each other within the system's boundaries (form, structure, organization) to function as a whole. The nature (purpose, operation) of the whole is always different from, and more than, the sum of its unassembled collection of parts.
What IS optimization?
optimization is a process or methodology of designing or making a product, process or system to the point at which it is the most fully functional, effective, or as near perfection as possible
A technology system is a combination of?
materials, devices, structures, information and energy working together to solve problems and extend human capabilities.
What is a open-loop system?
An open-loop system is a control system that has no means for comparing the output (the results of the operation of any system) with input (something put into a system, such as resources, in order to achieve a result) for control purposes. Control of open-loop systems often requires human intervention.
What are constraints?
Limitations
What IS a complex system?
A complex system is a system whose properties are not fully explained by an understanding of its component parts. Complex systems consist of a large number of mutually interacting and
interwoven parts, entities or agents.
What IS optimization used for?
Optimization is used for a specific design purpose to enhance or to make small gains in desirable characteristics
What IS technological process?
inputs-processes-outputs-feedback
What are delayed outputs?
chemicals that have accumulated over decades and now are harmful to the environment. Example: Sulfur dioxide produced by coal-fired power plants.
What are design principles
Established design principles are used to create designs across all technologies and to evaluate designs
Human intervention is used when what?
The more parts and connections in a
system, the more likely it is that something may not
work properly
Trade-Off Involves what?
Trade-off involves a choice or exchange for one quality over another.
Define PIMTECT
People, information, tools, energy, capital, time
What IS process in technological system?
process is a systematic sequence of actions that combines resources to produce an output — encoding, reproducing, designing, or propagating,
What can criterion be?
size, color, shape, etc.
Complex systems can be ethier?
Open-loop or closed-loop
What IS quality control?
Quality control is a planned process to ensure that a product, service, or system meets established criteria.
What are resources for technology?
Anything that is human made and or invented by mankind and can be used to make any form of technological designs
What are the 6 output results?
Desirable, delayed, immediate, unintended, intended, undesirable
What are the design principles? (explain them)
Function: the purpose of an object aesthetics: involves all your senses- vision, hearing, touch, taste, and smell- and your emotions. efficiency
Electricity is a complex system because?
Electricity is vital for most everyday activities. From the moment you flip the first switch each morning, you are connecting to a huge complex system — a network of people, electric lines, and generating equipment.
Opportunity cost IS?
The second-best alternative (or the value of that alternative) that must be given up when scarce resources are used for one purpose instead of another.
