The Internet of Things (IoT) is a revolutionary technology that connects various devices to the internet, enabling them to collect and exchange data seamlessly. The NPTEL course on Introduction to IoT has been enlightening students on the core concepts and applications of IoT. In Week 7 of this course, students are presented with Assignment 7, which challenges them to apply their knowledge to solve a practical problem. In this article, we will guide you through the process of tackling Week 7's assignment effectively.
Understanding IoT
Before diving into the assignment, let's recap the fundamental concepts of IoT. IoT refers to the interconnectedness of devices, sensors, and objects through the internet. It empowers these devices to communicate and share data, leading to smarter decision-making and automation in various domains like healthcare, agriculture, and smart cities.
1. **Raspberry Pi is like a mini computer which can perform a wide range of general-purpose tasks.**
- Answer: a. True
- Reason: Raspberry Pi is indeed a mini-computer that can perform a wide range of general-purpose tasks. It has a CPU, RAM, storage, and can run various operating systems and software applications, making it versatile for different computing needs.
2. **What is the complete form of GPIO pins on Raspberry Pi devices?**
- Answer: c. General Purpose Input/Output
- Reason: GPIO stands for "General Purpose Input/Output." These pins on a Raspberry Pi can be configured as either inputs or outputs and are commonly used to interact with sensors, LEDs, and other hardware components.
3. **The Python program which you execute on Raspberry Pi to read data from sensors and control actuators has the same syntax and style as any other Python program.**
- Answer: b. True
- Reason: Python programs on a Raspberry Pi for sensor data reading and actuator control have the same syntax and style as any other Python program. Raspberry Pi uses Python as one of its primary programming languages, so the code structure remains consistent.
4. **During remote server access by a Raspberry Pi, where the Raspberry Pi acts as a client, the client needs the following?**
- Answer: c. Both server IP address and port number
- Reason: When a Raspberry Pi acts as a client to access a remote server, it needs both the server's IP address to locate the server and the port number to specify the service it wants to communicate with on the server.
5. **Which among the following are valid data processing activities?**
- Answer: d. All of the given
- Reason: All the mentioned activities—data splitting, data filtering, and data plotting—are valid data processing activities. These tasks are commonly performed when working with data in various applications and programming contexts.
6. **Consider the following Python code snippet. What will be the output?**
```python
var = 'Sensor@Actuator%Arduino'
pt = var.split('%')
print(pt)
```
- Answer: a. ['Sensor', 'Actuator', 'Arduino']
- Reason: The `split('%')` function will split the string `var` at each occurrence of the '%' character, resulting in a list containing ['Sensor', 'Actuator', 'Arduino'].
7. **Which among the following functions do you use while using MATPLOTLIB to add a title to a plot?**
- Answer: d. title()
- Reason: In Matplotlib, you use the `title()` function to add a title to a plot. This title provides information about the content or purpose of the plot.
8. **In a traditional non-software-defined network consisting of a network of switches, suppose OSPF is being used as the routing protocol. In this context, which among the following is true?**
- Answer: a. All the switches execute OSPF distributively
- Reason: In a traditional network using OSPF (Open Shortest Path First) as the routing protocol, OSPF is executed distributively on all participating routers and switches. Each device calculates its own routing tables based on OSPF information.
9. **In SDN, the Operating System (OS) is separated (i.e., not strongly coupled) from the physical hardware for each switch.**
- Answer: a. True
- Reason: In Software-Defined Networking (SDN), the operating system (OS) is separated from the physical hardware of each switch. This separation allows for more flexibility and programmability in controlling network behavior.
10. **Which among the following is a popular protocol implementing SDN?**
- Answer: c. OpenFlow
- Reason: OpenFlow is a popular protocol used to implement SDN. It enables the centralized control of network devices, making it a key component of SDN architectures.
11. **With respect to Software Defined Networking (SDN), which among the following is true?**
- Answer: c. SDN separates the data plane and control plane.
- Reason: SDN separates the data plane (responsible for forwarding data packets) from the control plane (responsible for making decisions about how data should be forwarded). This separation allows for centralized network control and programmability.
12. **To which issue of SDN does this particular figure can be related to?**
- Answer: a. Controller placement issue
- Reason: Without the specific figure mentioned, it's challenging to provide a precise answer. However, if the figure illustrates the placement or distribution of SDN controllers within a network, it would be related to the "Controller placement issue" in SDN.
13. **Suppose that there are two LANs, each configured to be SDN-enabled with their own set of switches and controller. Which among the following directional APIs will be used for communication between the two controllers?**
- Answer: b. East-Westbound API
- Reason: The East-Westbound API is used for communication between SDN controllers in different LANs or domains. It enables the exchange of information and policies between controllers in a multi-controller SDN environment.
14. **Which among the following is true?**
- Answer: c. Backup controllers take over when the main controller goes down
- Reason: In SDN, backup controllers are designed to take over when the main (primary) controller becomes unavailable or goes down. This redundancy helps ensure network stability and availability.
15. **IoT being data-intensive and having a lot of security concerns, it is a good idea to integrate SDN with IoT to mitigate many of these issues.**
- Answer: a. True
- Reason: Integrating Software-Defined Networking (SDN) with the Internet of Things (IoT) can be a good idea. SDN allows for better management, control, and security of IoT devices and the data they generate. This integration can help mitigate many of the security concerns associated with IoT and optimize data handling in IoT networks.
