The main advantage of using edge computing is its ability to process data closer to the source, reducing latency and enhancing real-time data analysis. By decentralizing computing resources, edge computing minimizes the distance data must travel between devices and processing centers. This is particularly beneficial for applications requiring quick responses, such as IoT devices and real-time analytics. Additionally, edge computing can reduce bandwidth usage by filtering and processing data locally before sending it to the central cloud, leading to improved overall efficiency and resource management.
