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 money a business makes after all expenses have been paid






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






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






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






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






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






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






8. Someone who starts a business.






9. 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.






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






11. The basic framework of a system






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






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






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






15. The splitting of the nucleus of an atom.






16. The formal rules that guide the design process.






17. 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.'






18. Energy in motion.






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






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






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






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






23. 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.






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






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






26. 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.






27. The capacity to do work or exert effort.






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






29. 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.






30. A device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.






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






32. A production process in which the part or product moves down a line from one station to the next while parts are added.






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






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






35. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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






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






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






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






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






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






49. A resource that is entered into a system.






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