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






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






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






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






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






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






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






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






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






10. 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.






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






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






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






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






15. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.






16. A resource that is entered into a system.






17. The splitting of the nucleus of an atom.






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






19. 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.






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






21. Energy in motion.






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






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






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






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






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






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






28. Restriction or limit placed on a product.






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






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


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






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






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






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






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






36. A popular movement.






37. The use of simple machines to multiply the output force of a mechanical system.






38. Stored energy or energy at rest.






39. 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.






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






41. 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.






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






43. The capacity to do work or exert effort.






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






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






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






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






48. A production system in which products are made one at a time according to customer's specifications.






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






50. 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.'
