This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “AIDC Technologies – Two Dimensional Barcodes”.
1. Which type of barcode has the reduced area than the conventional barcode?
a) Cellular Barcodes
b) Fixed Beam Barcodes
c) Stacked Barcodes
d) Moving Beam Barcodes
View Answer
Explanation: The type of barcode which reduces the need for maximum area than the conventional barcode is known as stacked barcodes. It consists of multiple rows of conventional linear bar codes stacked on top of each other.
2. The data density of linear bar code-39 barcodes is seven times higher than stacked barcodes.
a) True
b) False
View Answer
Explanation: The data density of stacked barcodes bar codes is seven times higher than that of linear bar code-39. The drawback of stacked barcodes is that it requires special scanning equipment.
3. Which device is used to decode the encoded data in stacked barcodes?
a) Laser Type Scanners
b) Ceramic Plate
c) Steel Plate
d) Glass
View Answer
Explanation: The device which is used to decode the encoded data in stacked barcodes is known as laser type scanners. It will be used to read the lines sequentially.
4. Which of the following consists of 2-D patterns of data cells?
a) Nucleus
b) Matrix Symbology
c) Algorithm
d) Data Structure
View Answer
Explanation: Matrix Symbology will have 2-D patterns of data cells. They are usually square and may be colored in either black or white. It has the capability to hold large amount of data than the stacked barcodes.
5. How are matrix symbologies otherwise termed as?
a) Size Symbologies
b) Area Symbologies
c) Pattern Symbologies
d) Volume Symbologies
View Answer
Explanation: Area Symbologies is the other term given to matrix symbologies. The symbols which are used in matrix symbologies will be produced during printing and interpreted during reading in both horizontal and vertical direction.
6. Which system is used to read the data matrix?
a) Monitoring System
b) Machine Vision System
c) Signature System
d) Printing System
View Answer
Explanation: The system which is typically used to read the data matrix is known as machine vision system. This system will be specially programmed in order to interpret the code.
7. Which of the following has been adopted by the semiconductor industry for marking and identifying wafers and electronic components?
a) Poly coder VCC234
b) Data Matrix ECC200
c) Decoder 549
d) Data Encoder SCC 300
View Answer
Explanation: The latest technology which has been adopted by the semiconductor industry for marking and identifying wafers and electronic components is data matrix ECC200. It is a variation of the data matrix code.
