This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “AIDC Technologies – Set 2”.
1. Which category of AIDC technology uses touch screens and button memory?
a) Optical
b) Magnetic
c) Touch Technique
d) Electromagnetic
View Answer
Explanation: The Touch Technique automatic identification and data capture uses touch screens and button memory. It is user friendly and has higher reach among domestic as well as industrial applications.
2. Which category of AIDC technology is used to identify humans and to interpret vocal commands?
a) Optical
b) Magnetic
c) Touch Technique
d) Biometric
View Answer
Explanation: The Biometric technique of automatic identification and data capture is used to identify humans and interprets vocal commands of humans. It includes voice recognition, fingerprints and retinal eye scans.
3. What does OCR mean?
a) Optical Character Recognition
b) Ovular Character Recognition
c) Optical Character Reader
d) Optical Chain Recorder
View Answer
Explanation: OCR means Optical Character Recognition. This technology has medium error rate and cost. The drawback of this technique is that it has low data density.
4. Which is termed as the probability of the scanner to read successfully in its first attempt?
a) FRR
b) SRR
c) FSR
d) SRF
View Answer
Explanation: The probability of the scanner to read successfully in its first attempt is termed as FRR. The abbreviated form of FRR is First Read Rate. SRR, FSR and SRF were not defined as the probability of the scanner to read successfully in its first attempt.
5. Which is termed as the frequency with which the scanner incorrectly reads the encoded characters?
a) FER
b) SER
c) FSR
d) SRF
View Answer
Explanation: The frequency of the scanner with which it incorrectly reads the encoded characters as some other characters is known as SER. The abbreviated form of SER is Substitution Error Rate.
6. How is the expected number of errors calculated while reading encode data?
a) SER – n
b) SER * n
c) SER / n
d) SER + n
View Answer
Explanation: The expected number of errors calculated while reading encode data is calculate as SER * n where, SER stands for Substitution Error Rate and n stands for the number of characters.
7. The objective of AIDC system is to have a low FRR and high SER.
a) False
b) True
View Answer
Explanation: The objective of Automated Identification and Data Capture system is to have a high FRR and low SER. FRR stands for First Read Rate and SER stands for Substitution error Rate.
