Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Current flow in which electrons move in only one direction.






2. The path by which a message travels from the sender to receiver.






3. The capacity to do work or exert effort.






4. The judgement of the end result based upon given criteria.






5. Restriction or limit placed on a product.






6. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






7. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






8. Current flow in which electrons reverse direction at regular intervals.






9. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






10. Stored energy or energy at rest.






11. A group of people working together to accomplish a common goal.






12. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






13. The use of a computer system to produce technical drawings and/or design a product.






14. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






15. The process of turning abstractions of thought into concrete ideas.






16. A popular movement.






17. The path by which electric current or pulses flow.






18. Creating things through the process of planning.






19. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






20. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.






21. A language - used to write computer programs - that can easily be translated into machine language.






22. Someone who starts a business.






23. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






24. The law that states that if the pressure of a gas increases - the volume decreases (provided that the temperature remains constant).


25. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.






26. The use of lasers to record realistic images of three- dimensional objects.






27. The number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.






28. The technology field focused on sending messages and other in formation using different means.






29. The field of knowledge relating to materials as they exists on a molecular or atomic level.






30. The act of breaking a particular subject into different parts to achieve clarity of understanding.






31. The use of force to act on an object in order to move move the object in the same direction as the force.






32. Energy in motion.






33. The act of putting different things together to form a new product or idea.






34. The amount of resistance the power system must overcome or - alternatively - the amount of force output by the power system: also can be referred to as weight or pressure.






35. A group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






36. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






37. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






38. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






39. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






40. The use of pressurized liquid or gasses to control and transmit power.






41. The formal rules that guide the design process.






42. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






43. A unit that collects waves and decodes information contained within those waves.






44. Trade of products and services on a global scale.






45. The use of computers in each stage of the design process.






46. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






47. A circuit in which electricity flows along a single path to more than one device.






48. The unlawful acquisition of some one's personal information for use without their consent.






49. The superimposition of sine waves on electromagnetic carrier waves.






50. A method of obtaining energy from waste products
