This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “AIDC Technologies – Radio Frequency Identification”.
1. Which of the following will be attached to the subject item in RFID technique?
a) Rubber grip
b) Plastic Band
c) Identification Tag
d) Hook
View Answer
Explanation: Identification Tag will be attached to the subject item in RFID technique. It will contain electronically encoded data. It will consist of an integrated circuit chip and a small antenna.
2. What does EPC mean in terms of product coding?
a) Electronic product Code
b) Elevated product Code
c) Even Product Code
d) Eleventh Product Code
View Answer
Explanation: The abbreviated form of EPC is Electronic Product Code. It is a standard according to which the identification tag or label are usually designed in Radio Frequency Identification technique.
3. Which of the following is a device that will emit a signal of its own when it receives a signal from an external source?
a) Receiver
b) Reflector
c) Absorber
d) Transponder
View Answer
Explanation: The device which has the ability to emit a signal of its own when it receives a signal from an external source is known as transponder. In Radio frequency identification technique, the identification tag or label acts as a transponder.
4. Which type of identification tags will have no internal power source?
a) Bipolar Tags
b) Passive Tags
c) Modular Tags
d) Active Tags
View Answer
Explanation: The identification tags which will have no internal power source are known as passive identification tags. They derive the electrical power required for transmitting a signal from radio waves generated by the reader.
5. Which type of identification tags will have their own battery packs?
a) Modular Tags
b) Active Tags
c) Mixed Tags
d) Passive Tags
View Answer
Explanation: The type of identification tag which will have their own battery power packs is known as active identification tag. It is usually enclosed in a protective plastic container or sandwiched between abrasives to ensure safety precautions.
6. The cost of bar code is low compared to that of RFID?
a) False
b) True
View Answer
Explanation: The cost of bar code will be very low when compared to that of RFID, The cost of RFID will be 10 times higher than that of barcodes.
7. What will be the storage capacity of RFID?
a) 10-50 digits
b) 96-256 Digits
c) 0-5 Digits
d) 80-100 Digits
View Answer
Explanation: The storage capacity of Radio Frequency Identification and Data Capture technique is about 96-256digits. 10-50 digits, 0-5 Digits and 80-100 Digits were not the typical storage capacity of RFID.
8. What is meant by RFDC in terms of ADIC?
a) Reversal Frequency Data Control
b) Radio Frequency Data Communication
c) Radar Frequency Data Control
d) Rapid Frequent Data Control
View Answer
Explanation: The abbreviated form of RFDC is Radio Frequency Data Communication. It is the latest version of RFID which is used to provide the communication link between remote bar code readers and some central terminal.
9. Which type of signal does the reader decodes and confirms before transmitting it to a collection computer?
a) DC Signal
b) RF Signal
c) PF Signal
d) AF Signal
View Answer
Explanation: The type of signal with which the reader decodes and confirms before transmitting the related data to a collection computer is RF signal in RFID technique. RF signal stands for Radio Frequency Signal.
10. Passive tags have larger memory space and longer communication range in RFID technique.
a) False
b) True
View Answer
Explanation: In Radio Frequency Identification and Data Capture technique, active identification tags or labels will have larger memory space than the passive tags. It will also have larger communication range.
