Week 0 Assignment Questions and Answers:
Question 1:
Which of the following allows us to identify objects and extract information?
- a. RFID
- b. Sensors
- c. Actuators
- d. IoT Nodes
Answer:
a. RFID
RFID (Radio Frequency Identification) technology allows us to identify objects and extract information from them using electromagnetic fields.
Question 2:
How many layers does Zigbee consist of?
- a. 1
- b. 2
- c. 3
- d. 4
Answer:
d. 4
Zigbee consists of 4 layers: the Physical (PHY) layer, Medium Access Control (MAC) layer, Network (NWK) layer, and the Application (APL) layer.
Question 3:
Which of the following is not a component of cloud computing?
- a. Clients
- b. Local Servers
- c. Services
- d. Applications
Answer:
b. Local Servers
Local servers are not a component of cloud computing, which typically relies on remote servers to provide services and applications to clients.
Question 4:
Which of the following is a distance measuring sensor module?
- a. DHT22
- b. HC-SR04
- c. TSL2591
- d. HC-SR505
Answer:
b. HC-SR04
The HC-SR04 is a sensor module used for measuring distance using ultrasonic waves.
Question 5:
Which of the following is a component in a typical sensor network?
- a. Sink
- b. Gateway
- c. Router
- d. All of these
Answer:
d. All of these
In a typical sensor network, components like sinks, gateways, and routers are used to collect and transmit data.
Question 6:
Which of the following sensors are responsible for measuring orientation and angular velocity?
- a. Accelerometer
- b. GPS
- c. Temperature
- d. None of these
Answer:
a. Accelerometer
An accelerometer is responsible for measuring orientation and angular velocity.
Question 7:
“ISA 100.11A” is a wireless networking technology standard. ISA stands for:
- a. International Society of Automation
- b. International Society of Advancement
- c. Industrial Society of Automation
- d. Industrial Society of Advancement
Answer:
a. International Society of Automation
ISA stands for International Society of Automation, which developed the ISA 100.11A wireless networking technology standard.
Question 8:
Which of the following is not a difference between traditional data center and cloud computing?
- a. Scalability
- b. Flexibility
- c. Elasticity
- d. Storage
Answer:
d. Storage
Storage is a component of both traditional data centers and cloud computing; differences lie in scalability, flexibility, and elasticity.
Question 9:
Smart grid is also known as the energy internet.
- a. True
- b. False
Answer:
a. True
The smart grid is often referred to as the energy internet because it integrates information technology with the power grid for efficient energy management.
Question 10:
Can a point of node failure result in the partition of the network in the stationary sensor network?
- a. Yes
- b. No
Answer:
a. Yes
A point of node failure can indeed result in the partition of the network in a stationary sensor network, disrupting communication paths.
