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 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.'






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






3. 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.






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






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






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






7. The basic framework of a system






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






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






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






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






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






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






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






16. 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.






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






18. A popular movement.






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






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






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






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






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






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






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






26. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






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






37. Restriction or limit placed on a product.






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






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






40. 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.






41. The capacity to do work or exert effort.






42. A method of obtaining energy from waste products






43. Creating things through the process of planning.






44. Someone who starts a business.






45. 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.






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






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






48. The splitting of the nucleus of an atom.






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






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