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.

19. A electrical property of matter that exist because of an excess or a deficiency of electrons. Can be either positive or negative






20. A notational system for logic symbols that specifies input and output relationships thus fully defining a given function






21. A relatively small - high- speed memory that stores the most recently used instructions or data from the larger but slower main memory






22. The application of a dc voltage to an electronic device to produce a desired mode of operation






23. A circuit (digital service) that switches digital data from one input line to several output lines in a specified time sequence






24. Burst extended data output dynamic random- access memory






25. A unit of logic in an FPGA that is made up of multiple smaller logic modules and a local programmable interconnect that is used to connect logic modules within the CLB






26. A method for internally testing a PLD based on the JTAG standard (IEEE std.)






27. Basic input/output system; a set of programs in ROM that interfaces the I/) devices in a computer system






28. One of the three regions in a bipolar junction transistor






29. Arithmetic Logic Unit; the key processing element of a microprocessor that perfoms arithmetic and logic operations.






30. The inverse of opposite of a number - in Boolean algebra - the inverse function - expressed with a bar over the variable. The complement of a 1 is a 0 - and vice versa






31. A type of IC package whose leads must pass through holes to the other side of a PC board






32. The smallest particle of an element possessing the unique characteristics of that element.






33. Dual in - line memory module






34. Dynamic random- access memory; a type of semiconductor memory that uses capacitors as the storage elements and is a volatile - read/write memory






35. A logic gate that produces a High output only when all of the inputs are HIGH






36. An energy source that uses a chemical reaction to convert chemical energy into electrical energy.






37. A resettable protective device used for interrupting execessive current in an electric circuit






38. The interval of time occupied by a single bit in a sequence of bits; the period of the clock

41. In Boolean algebra - the OR operation






42. A digital circuit capable of counting electronic events - such as pulses - by progressing through a sequence of binary states.






43. In addition (ORing) and multiplication (ANDing) of two variables the order in which the variables are ORed or ANDed makes no difference






44. A number given in ampere- hours determined by multiplying the current times the length of the time (h) a battery can deliver that current to a load






45. To connect 'end- to- end' as when several counters are connected from the terminal count output of one counter to the enable input of the next counter






46. To decrease the binary state of a counter by one






47. An instrument that can specify each of the other instruments on the bus as either a talker or a listener for the purpose of data transfer.






48. A combined coder and decoder






49. The mathematics of logic circuits
