Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data. This helps to:
* Reduce Latency: By processing data closer to where it is generated, edge computing reduces the time taken for data to travel to a central server and back. This is especially important for applications requiring real-time or near-real-time responses.
* Optimize Bandwidth: Reducing the amount of data sent to a central data center can conserve bandwidth and lower costs.
* Enhance Security and Privacy: Processing data locally can enhance security and privacy by minimizing the exposure of data during transmission.
