What is Latency?

The time delay between sending a request and receiving a response, measured in milliseconds.

Latency measures the round-trip time for data to travel between source and destination. It is affected by physical distance, network congestion, routing hops, and processing time at each node.

Low latency is critical for real-time applications like gaming, video calls, and financial trading. CDNs, edge computing, and protocol optimization reduce latency.
