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






2. Giga






3. An electrical device used to store electrical charge.






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






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






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






7. V or E and Volt (V)






8. 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.






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






10. Giga






11. An electrical device used to store electrical charge.






12. P and Watt (W)






13. Mega






14. C and Farad (F)






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

23. Pico






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






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






26. 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.






27. 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.






28. Nano

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






38. 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






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






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






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

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






48. 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.






49. Tera






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