# Overview
Latency is the time is takes for data to pass from one on a network to another. It is impacted by physical distance between two nodes in the network. It is measured in milliseconds (ms).
One common approach to address latency in web applications is through a [[Content Delivery Network (CDN)]].
# Key Considerations
## Network Latency Components
processing delay: the time routers take to process the requested data, (ii) **queuing delay: the routing queue time of data**, and (iii) propagation delay: the time for data to be delivered to users
## Latency Levels
