Edge computing processes data near its source like IoT devices, sensors, or local servers instead of distant cloud centers.

It works by analyzing data locally first, reducing the need to send everything to the cloud.

Latency drops from 50-200 ms (cloud) to 1-10 ms or even less with edge computing.

It saves bandwidth by filtering data locally, cutting costs and reducing network congestion.

Edge systems keep working even without internet, ensuring reliability in remote or critical locations.

Better security as sensitive data stays local, lowering risks of cyber attacks or data leaks.

Used in smart devices, factories, healthcare, and autonomous vehicles for real-time decisions.

5G and billions of IoT devices are driving edge computing growth across industries.

Challenges include higher setup cost, complex management, and scaling edge with cloud systems.
