This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Input and Output Devices for Discrete Data”.
1. Which is a device by which binary data are read into the computer from some external source?
a) Contact Input Interface
b) Contact Mixed Interface
c) Contact Output Interface
d) Contact Hybrid Interface
View Answer
Explanation: The device by which binary data are read into the computer from some external source is known as Contact Input Interface. It consists of a series of contacts that can be either turned or off.
2. Which of the following is a device that communicates on/off signals from the computer to the process?
a) Contact Input Interface
b) Contact Mixed Interface
c) Contact Output Interface
d) Contact Hybrid Interface
View Answer
Explanation: The device that communicates on/off signals from the computer to the process is known as Contact Output Interface. The sequence of on/off activities in a work cycle will be controlled by the computer through this mode.
3. Which is a device that converts a series of pulses into a digital value?
a) Terminator
b) Pulse Counter
c) Regulator
d) Pulse Generator
View Answer
Explanation: The device which converts a series of pulses into a digital value is known as pulse counter. It can be used for both counting and measuring applications. Terminator, Regulator and Pulse Generator are not typically used to convert series of pulses into digital value.
4. Which of the following is an electronic device that possesses memory capability to store the results of counting procedure?
a) Comparator
b) Integral Hold
c) Top Tip
d) Flip Flop
View Answer
Explanation: An electronic device that possesses memory capability to store the results of counting procedure is known as flip flop. It will be constructed using sequential logic gates.
5. Which of the following is an electronic device that produces a series of electric pulses whose total number and frequency are determined and sent by the control computer?
a) Comparator
b) Pulse Generator
c) Top Tip
d) Flip Flop
View Answer
Explanation: An electronic device that produces a series of electric pulses whose total number and frequency are determined and sent by the control computer is known as pulse generator. The motors used in the positioning system will be driven by the pulses generated.
