What is Latency?
Latency is the time it takes for a data packet to travel from its source to its destination, usually measured in milliseconds. Low latency means data arrives quickly, which is critical for real-time applications like video calls and online gaming. Latency is influenced by factors such as physical distance, network congestion, and the number of hops between devices.
