Network latency is the time it takes for data to travel from its source to its destination across a network. Think of it as the delay between when you click a link and when your browser starts receiving the webpage. Higher latency causes slower loading times – for example, a latency of 200 milliseconds means it takes one-fifth of a second for your action to reach the server. Low latency creates a faster and smoother browsing experience.
