Match the following:
| COLUMN A | COLUMN B |
| :------------------------------------------------------- | :--------------- |
| 1. Automated AC control system in a smart home | a. Edge devices |
| 2. Wearable health monitor | b. Gateways |
| 3. Traffic camera at a road intersection | |
Answer (2)
All three items in Column A—Automated AC control system, Wearable health monitor, and Traffic camera—are classified as edge devices. They process data locally, making them efficient and responsive. Therefore, the correct matches are each with 'a. Edge devices'.
;
Automated AC control system, wearable health monitor, and traffic camera are identified as devices that process data locally.
These devices operate at the edge of the network, close to the data source.
Therefore, all three items match 'a. Edge devices'.
The final matching is: 1-a, 3-a, 4-a.
Explanation
Analyzing the Problem We need to match items from Column A to the correct device type in Column B. Let's analyze each item in Column A to determine whether it functions as an edge device or a gateway.
Identifying Edge Devices
Automated AC control system in a smart home: This system collects data from sensors (temperature, humidity) and makes decisions to adjust the AC. It's a device that processes data locally.
Wearable health monitor: This device collects health data (heart rate, steps) and may perform some initial processing before sending it to a central system.
Traffic camera at a road intersection: This camera captures video data and may perform some processing (e.g., license plate recognition) before sending it to a central traffic management system.
Matching to Edge Devices All three items (Automated AC control system, Wearable health monitor, and Traffic camera) are examples of edge devices because they perform data processing at the edge of the network, close to the data source. Therefore, they should be matched with 'a. Edge devices'.
Final Matching Therefore, the correct matching is:
Automated AC control system in a smart home - a. Edge devices
Wearable health monitor - a. Edge devices
Traffic camera at a road intersection - a. Edge devices
Examples
Imagine you're building a smart home. Edge devices like smart thermostats and security cameras process data locally, making quick decisions without relying on a central server. This reduces latency and improves responsiveness, ensuring your home automation system works efficiently and reliably. Similarly, in a factory, edge devices can monitor equipment and detect anomalies in real-time, preventing costly downtime. This distributed approach enhances overall system performance and resilience.
