Latency is the amount of time it takes for data to travel over the Internet or a network from one point to another. It is typically measured in milliseconds (ms) and is influenced by factors such as the distance between the two points, the speed of the network, and the number of devices or hops between them. Higher latency can have a significant impact on network performance, particularly in real-time applications and those requiring quality of service (QoS). Reducing latency can be achieved through techniques such as optimizing network hardware and software, reducing the distance between endpoints, and implementing protocols that prioritize real-time traffic. Utilizing dedicated network connections can provide lower latency as well. Latency is also known as Network Delay.
