Edge computing involves processing data closer to the source of generation, reducing latency and improving efficiency. It is used in applications that require real-time processing, such as IoT devices, smart cities, and industrial automation.

Edge computing is essential due to its ability to significantly reduce latency, enabling faster response times for critical applications such as IoT devices, autonomous vehicles, and real-time analytics. By processing data closer to its source at the edge of the network, it optimizes bandwidth usage, reduces network congestion, and improves overall data transfer efficiency.

Moreover, edge computing enhances reliability by minimizing dependencies on centralized infrastructure, ensuring continuous operations even in the event of network disruptions. It also strengthens data privacy and security by allowing sensitive information to be processed and analyzed locally, reducing the risk of data breaches during transmission.

Edge computing is a paradigm that involves processing data closer to the source of generation, typically at the edge of the network, rather than relying solely on centralized data centers. This approach reduces latency, improves efficiency, and enables real-time processing of data, making it ideal for applications that require immediate insights and actions. Edge computing is widely used in industries such as IoT (Internet of Things), smart cities, industrial automation, and autonomous vehicles, where rapid data processing and low latency are crucial.
