Edge computing devices are designed to perform data processing and storage closer to the source of the data, so that the data doesn’t have to be sent to a cloud or central data center for processing. As such, edge computing devices require a different set of hardware components compared to traditional computing systems. Here are some of the key hardware components used in edge computing devices:
1. Processors: Edge computing devices use a range of processors, including CPUs, GPUs, and FPGAs, to perform data processing. These processors have varying levels of processing power and are chosen based on the specific use case and data processing requirements.
2. Memory: Edge computing devices require memory to store data and perform operations. They use different types of memory, including RAM, cache memory, and flash memory, depending on the specific use case and processing requirements.
3. Sensors: Edge computing devices often have sensors that help to collect and transmit data from the environment. Examples of sensors used in edge computing devices include temperature sensors, humidity sensors, and light sensors.
4. Communication hardware: Edge computing devices need to communicate with other devices, including sensors, gateways, and the cloud. They use a range of communication hardware, including Wi-Fi, Bluetooth, and cellular networks, to do this.
5. Storage: Edge computing devices require storage to store data that is collected and processed locally. They use different types of storage, including hard disk drives, solid-state drives, and SD cards, depending on the specific use case and data storage requirements.
Some examples of edge computing devices include smart speakers like Amazon Echo and Google Home, smart cameras, and drones. Each of these devices uses a different combination of hardware components depending on their specific use cases and processing requirements.
