Question 6

Which of the following terms indicates that information is to be read only by those people for whom it is intended?
A)Availability
B)Accounting
C)Integrity
D)Confidentiality

Accepted Answer

Confidentiality refers to the principle of ensuring that information is accessible only to those authorized to have access, thus ensuring it is kept secret from anyone for whom it is not intended.

Question 7

What is the full form of SCADA?
A)Supervisory Control and Document Acquisition
B)Supervisory Control and Data Acquisition
C)Supervisory Column and Data Assessment.
D)Supervisory Column and Data Assessment

Accepted Answer

SCADA stands for Supervisory Control and Data Acquisition, which is a system for remote monitoring and control that operates with coded signals over communication channels.

Question 8

DCS is a ________
A)Distributed Control System
B)Data Control System
C)Data Column System
D)Distributed Column System

Accepted Answer

DCS stands for Distributed Control System, which is a type of automated control system that distributes control elements throughout the system rather than being centralized, commonly used in industrial processes.

Question 9

What is SCADA?
A)Software
B)Process
C)System
D)Hardware

Accepted Answer

The answer of What is SCADA?
A)Software
B)Process
C)System
D)Hardware...

Question 10

Which of the following is not the component of a SCADA system?
A)Database server
B)I/O system
C)PLC controller
D)Sparger controller

Accepted Answer

A SCADA (Supervisory Control and Data Acquisition) system typically includes components such as a database server to store data, an I/O system for interfacing with field devices, and PLC (Programmable Logic Controller) controllers for automating industrial processes. A sparger controller, which might be specific to controlling sparging processes (e.g., in bioreactors or brewing), is not a standard component of a SCADA system.

Question 11

Which of the following is not involved in working of IoT?
A)RFID
B)Sensor
C)Nano tech
D)Server

Accepted Answer

The answer of Which of the following is not involved...

Question 12

M2M is a term introduced by
A)IoT service providers
B)Fog computing service providers
C)Telecommunication service providers
D)None of these

Accepted Answer

M2M, or Machine to Machine, refers to direct communication between devices using any communications channel, including wired and wireless. This concept predates IoT (Internet of Things) and is widely used in telecommunications to describe technologies that allow networked devices to exchange information and perform actions without the manual assistance of humans. Telecommunication service providers introduced and have been instrumental in the development and deployment of M2M technologies.

Question 13

Which of these statements regarding sensors is TRUE?
A)Sensors are input devices.
B)Sensors can be analog as well as digital
C)Sensors respond to some external stimuli.
D)All of these

Accepted Answer

Sensors are indeed input devices that respond to external stimuli, and they can be either analog or digital, making all the provided statements true.
