Subject : it-skills
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. To disassociate the tag from a tagged object and optionally destroy it






2. UHF and microwave passive tags






3. Measurement of power for radiation of antenna used in US






4. Similar to guessing a number made of 1's and 0's by guessing each number one at a time






5. Die-cut web with adhesive - film face






6. Pattern(Footprint) - Power/Attenuation - and Polarization






7. changes signal received from reader to include data that will be transmitted back to the reader






8. Receives analog signals from the tag via the reader antenna






9. Open image in meshed screens. Conductive ink "squeezed" thru open mesh.






10. Process of creating a tag and uniquely associating it with an object






11. Serves as writable or non-writable data storage






12. Class= Functionality - - Class 0 -1 -2 -3 -4 & 5






13. Used for storing data such as the reader configuration parameters and a list of tag reads






14. IC Chip - Antenna/Inductor - Power Source






15. Reader transmits a continuous-wave RF signal into the reading environment






16. Can reduce power by placing this device in the transmission line. As a result - the antennas signal is reduced and the read range diminished. Proves useful in situations where the read zone needs to be constrained as a part of system requirements so






17. Smart cards - smart label - etc.






18. More than one tag tries to respond to a reader at the same time.






19. RF energy radiates from antenna in linear fashion - Provide longest range - Sensitive to the orientation of tag - Has single E-field component - Can have a narrow beam pattern - Best for application with known tag orientation






20. Receives signal from reader and radiates a response back to the reader - LF or HF: induction coil - UHF or Microwave Frequency: printed antennas






21. Tags collide completely or not at all (Theoretically proven maximum utilization= 36.8%)






22. Every time a tag is read - it is saved to this






23. Standards = EPC global & ISO 18000 - Different Organizations






24. Used to transmit AC power and the clock cycle via its antennas to the tags in its read zone






25. LF and HF passive tags - Current flowing through a conductor generates a magnetic field around the conductor and vice versa - Readers antenna uses current to generate magnetic field - Tag's antenna when exposed to the magnetic field generates the cur






26. The 3D energy field generated by the antenna (also called reading area)






27. Can automatically turn on/off reader based on some external event detected. Can be used to provide some kind of input trigger to a reader






28. Also called an 'interrogator' - A device that can read from and write data to compatible RFID tags - Also doubles up as a writer






29. In this this antenna type - the RF waves emanate in a linear pattern from the antenna. Waves have only one energy field






30. Uses a serial communication link to communicate with an application - Reader is physically connected to a computer's serial port using an RS-232 or RS-485 serial connection. Both of these connections have an upper limit on the cable length that can b






31. One of the most versatile actuators. Widely used in manufacturing plants. They enable a variety of actions to be performed (such as monitoring and controlling a product packaging line - or applying a predetermined amount of torque to nuts in a mechan






32. Inductive coupling and passive backscatter (capacitive coupling)






33. Also called a fixed reader - Mounted on a wall - portal - or some suitable structure in the read zone. Readers not generally very tolerant of harsh environmental conditions - therefore if installed outdoors or on moving objects - take care to ruggedi






34. These are categorized into Aloha based protocols and tree based






35. Readability of a tag greatly depends on this and the angle at which the tag is presented to the reader






36. Broadcasts the reader transmitter's RF signal into its surroundings and receives tag responses on the reader's behalf. Therefore - proper positioning of these (NOT THE READERS) is essential for good read accuracy






37. The sender of this found out whether the transmission was successful by listening to the broadcast. If there was a collision - the sender transmitted after a random waiting period. The tags periodically send data packets with random quiet periods and






38. Mount the tiny chip to a strap - Greater handling ability - Possibility to use very small chips - Possibility of higher volume production - Fluidic Self Assembly






39. Developed in the 1970s for a radio packet network at the University of Hawaii (hence the name) - 4 tags and 1 reader - Allows tags to collide partially (Theoretically proven maximum utilization=18.4%)






40. RF energy radiates from antenna in circular fashion - Slightly reduced range - Provides greater tolerance to tags in various orientation and bounce off of and bypass obstructions - 2 E-field components that are equal in magnitude - 90 degrees out of






41. Determines the read zone of a reader - Also called an antenna pattern - 3D region shaped somewhat like an ellipsoid or a balloon projecting out the front of the antenna. Never uniformly shaped like an ellipsoid but almost always contains deformities






42. Frequencies between 30-300 KHz - Generally use passive tags - have low data-transfer rates from the tag to the reader - and are especially good if the operating environment contains metals - liquids - dirt - snow - or mud. Active tags also available






43. Provides electrical power to other tag elements - Can harvest power from the signal received from the reader - Can have its own internal power source - Active - semi-passive and passive






44. Die-cut web adhesive - paper face






45. 'Central nervous system' of entire RFID hardware system. Establishing communication with and control of this component is the most important task of any entity which seeks integration






46. Responsible for implementing the reader protocol to communicate with compatible tags






47. Fixed to meet FCC and other regulatory requirements. The signal can be decreased or attenuated to limit the tag read window or aim it only at tags you want to read






48. The reflection of reader antenna signals on RF-opaque causes this






49. Reader communicates to a tag through reader's antennas - a separate device that is physically attached to a reader - at one of its antenna ports - by means of cable. Called this because it creates an electromagnetic field to couple with the tag.






50. The orientation of the transmitted electromagnetic field or the direction of oscillation of electromagnetically emitted waves
