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. Mega






2. Micro






3. Are and Ohms






4. Mega






5. 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.






6. Kilo






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






8. Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.






9. Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.






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






11. A very common IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board.






12. The instantaneous voltage of a waveform. Often used to mean maximum amplitude - or peak voltage - or a pulse.






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






14. C and Farad (F)






15. An electrical device used to store electrical charge.






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






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






18. Nano






19. Signal in the form of a rectangular pulse train or a square wave.






20. Signal in the form of a rectangular pulse train or a square wave.






21. P and Watt (W)






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






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






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






25. Tera






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






27. P and Watt (W)






28. Micro






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






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






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






32. Milli






33. Nano






34. 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.






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






36. 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.






37. 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.






38. An electrical device used to store electrical charge.






39. I and Ampere or Amp (A)






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






41. Pico






42. A solder connection that exhibits poor wetting and is characterized by a grayish - porous appearance due to excessive impurities in the solder - inadequate cleaning prior to soldering - and/or the insufficient application of heat during the soldering






43. 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.






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






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






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






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






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






49. 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.






50. V or E and Volt (V)
