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. A popular movement.






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






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






4. 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.






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






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






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






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






9. 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.






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






11. Stored energy or energy at rest.






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






13. The basic framework of a system






14. The splitting of the nucleus of an atom.






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






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






17. 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.






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






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






20. 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.






21. Energy in motion.






22. 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.'






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






24. 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.






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






26. 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.






27. Someone who starts a business.






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






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






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






31. The formal rules that guide the design process.






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






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






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






35. 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.






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






37. Creating things through the process of planning.






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






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






40. A method of obtaining energy from waste products






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






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






43. A resource that is entered into a system.






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






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






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






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






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






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






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