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. I and Ampere or Amp (A)






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






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






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






5. Nano






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






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






8. 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.






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






10. Tera






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






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






13. Milli






14. 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.






15. Metallic alloy of tin and lead that is used to join two metal surfaces.






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






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






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






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






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






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






22. Mega






23. 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






24. Kilo






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






26. V or E and Volt (V)






27. 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.






28. V or E and Volt (V)






29. Micro






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






31. An electrical device used to store electrical charge.






32. Insulating board containing conductive tracks for circuit connections.






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






34. 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






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






36. The unwanted formation of a conductive path of solder between conductors.






37. Are and Ohms






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






39. Giga






40. A series of logic 1s and 0s plotted as a function of time.






41. Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.






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






43. Kilo






44. 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.






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






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






48. C and Farad (F)






49. Tera






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