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 superimposition of sine waves on electromagnetic carrier waves.






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






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






5. A resource that is entered into a system.






6. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






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






8. A device that orbits the Earth and receives messages from one location and transmits them to another.






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






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






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






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






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






14. The measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.






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






16. Standards that a product must meet to be accepted.






17. 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.






18. 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.'






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






20. Studying the effects of a given technology to determine its impact.






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






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






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






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






25. The use of 3D CAD drawings to create real models of a product within a sort of time.






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






27. Restriction or limit placed on a product.






28. 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.






29. The basic framework of a system






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






31. The splitting of the nucleus of an atom.






32. 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.






33. 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.






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






35. A circuit in which electricity flows along more than one path.






36. 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.






37. The formal rules that guide the design process.






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






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






40. Someone who starts a business.






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






42. 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.






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






44. Stored energy or energy at rest.






45. The capacity to do work or exert effort.






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






47. The capacity to do work or exert effort.






48. Processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.






49. The money a business makes after all expenses have been paid






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