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






2. 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.






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






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






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






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






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






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






9. A method of obtaining energy from waste products






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






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






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






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






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






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






16. The basic framework of a system






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






18. 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.'






19. Someone who starts a business.






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






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






22. The formal rules that guide the design process.






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






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






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






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






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






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






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






30. 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.






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






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






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






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






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






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






37. 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.






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






39. 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.






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






41. A popular movement.






42. The capacity to do work or exert effort.






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






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






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






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






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






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






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






50. 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.
