In the fast-paced digital world, where every millisecond counts, understanding the nuances of network latency becomes paramount for developers and system architects. Latency, the delay before a transfer of data begins following an instruction for its transfer, can significantly impact user experience and system performance.

When it comes to network performance, there are two main limiting factors that will slow you down: bandwidth and latency. the maximum rate of data transfer across a given path. Latency is defined as…. how long it takes for a bit of data to travel across the network from one node or endpoint to another.
