While edge computing focuses on processing data at the edge, "Distributed" computing focuses on local area networks and gateways. Distributed computing refers to the use of multiple interconnected computers and devices to process and manage data across a network, often in a decentralized manner, making it suitable for local network processing.

Arduino is a widely used platform for IoT development due to its open-source nature, ease of use, and extensive community support. Microsoft Word, Photoshop, and WhatsApp are not relevant tools for IoT development.

ISO 27001 is a widely recognized standard that focuses on information security, including the security of connected devices and their networks. ISO 9001 is related to quality management, IEEE 802.11 is a standard for wireless LANs, and MQTT is a messaging protocol.

Regulatory compliance in IoT is crucial to ensure that IoT devices and systems adhere to legal and industry standards. This encompasses privacy regulations, safety standards, and other legal requirements that IoT devices must meet to operate within a given jurisdiction.

By processing data at the source, "Fog" computing reduces latency in IoT applications. Fog computing extends cloud computing to the edge of the network, closer to where data is generated, reducing the need to transmit all data to a distant cloud server. This helps in real-time data processing and lower latency.

To manage IoT devices and monitor their health remotely, IoT Hub services in cloud platforms are designed for this purpose. IoT Hubs offer device management, health monitoring, and facilitate communication between IoT devices and cloud services. Device management and health monitoring are essential for large IoT fleets.

In Edge computing, intermediary nodes (often located closer to the end-devices) process data before it's sent to the cloud. This reduces latency and can be crucial for real-time or time-sensitive applications, making it a suitable choice for IoT scenarios.

The concept of "Right to be Forgotten," especially in the realm of IoT, is derived from "European Union (EU) Regulations." EU regulations emphasize individuals' right to have their personal data erased, which impacts IoT data privacy.

Rust is known for its lightweight and efficient characteristics, making it a suitable choice for resource-constrained devices like smart wearables. While Python, Java, and C are widely used, they may not be as efficient on such devices.

The primary layers of IoT architecture typically include the Application Layer, which is responsible for interacting with end-users and applications. It's where data is processed and used for various IoT applications.
