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. The superimposition of sine waves on electromagnetic carrier waves.






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






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






4. The capacity to do work or exert effort.






5. 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.






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






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






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






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






10. The basic framework of a system






11. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






12. 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.






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






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


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






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






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






18. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.






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






20. 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.'






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






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






23. Energy in motion.






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






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






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






27. A popular movement.






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






29. Current flow in which electrons move in only one direction.






30. Someone who starts a business.






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






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






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






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






35. Stored energy or energy at rest.






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






37. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






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






39. 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.






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






41. The formal rules that guide the design process.






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






43. Restriction or limit placed on a product.






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






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






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






47. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






48. The capacity to do work or exert effort.






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






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