Digital Electronics Vocab

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. Milli






2. C and Farad (F)






3. Pico






4. Are and Ohms






5. An IC package similar to a DIP - but smaller - which is designed for automatic placement and soldering on the surface of a circuit board.






6. Circuit that is capable of sensing and holding a signal until the event that changed the signal can be addressed.






7. P and Watt (W)






8. Giga






9. An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements - shaped like a figure-8 - which can be used to display decimal digits and other characters by turning on the appropriate elements.






10. A square IC package with leads on all four sides designed for surface mounting on a circuit board.






11. Abbreviation of System International - a system of practical units based on the meter - kilogram - second - ampere - Kelvin - mole - and candela.






12. Component made of material that opposes flow of current and therefore has some value of resistance.






13. The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential - which is in the opposite direction of electron flow.






14. A floating point system in which numbers are expressed as products consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three.






15. Abbreviation of System International - a system of practical units based on the meter - kilogram - second - ampere - Kelvin - mole - and candela.






16. Numbers entered as a number from one to ten multiplied by a power of ten.






17. An electrical device used to store electrical charge.






18. Are and Ohms






19. A circuit board for wiring temporary circuits - usually used for prototypes or laboratory work.






20. A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values.






21. V or E and Volt (V)






22. The smallest particle of an element that still has the same characteristics as the element.






23. A group of flip-flops (typically 4 or 8) that are arranged so that the values stored in the flip-flops are shifted from one flip-flop to the next for every clock.






24. A group of flip-flops (typically 4 or 8) that are arranged so that the values stored in the flip-flops are shifted from one flip-flop to the next for every clock.






25. A two terminal device that conducts in only one direction.






26. Nano






27. Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance.






28. A circuit the produces a digital output signal that is half the frequency of the input.






29. The process of applying a thin coat of solder to materials prior to their being soldered; for example - application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering the conductor.






30. Micro






31. F and Hertz (Hz) or Cycles per sec.






32. Circuit that is capable of sensing and holding a signal until the event that changed the signal can be addressed.






33. Milli






34. A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value.






35. Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them.






36. Any material that allows the free movement of electric changes - such as electrons - to provide an electric current.






37. A square IC package with leads on all four sides designed for surface mounting on a circuit board.






38. I and Ampere or Amp (A)






39. Kilo






40. Component made of material that opposes flow of current and therefore has some value of resistance.






41. A movement of electrical charges around a closed path or circuit.






42. Kilo






43. C and Farad (F)






44. A circuit the produces a digital output signal that is half the frequency of the input.






45. A way of representing some physical quantity - such as temperature or velocity - by a proportional continuous voltage or current. An analog voltage or current can have any value within a defined range.






46. Any material that allows the free movement of electric changes - such as electrons - to provide an electric current.






47. I and Ampere or Amp (A)






48. Micro






49. An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements - shaped like a figure-8 - which can be used to display decimal digits and other characters by turning on the appropriate elements.






50. F and Hertz (Hz) or Cycles per sec.
