The term latency in network communications refers to the delay between a user's action and the response from a server or device. It is a critical factor in determining the performance of a network, affecting how quickly data packets travel between endpoints. High latency can lead to slow loading times and disrupt real-time applications such as gaming, video conferencing, or online collaboration tools. Network architects strive to minimize latency through various means, including optimizing routing paths and using faster transmission mediums. Understanding latency is essential for delivering a satisfactory user experience in digital environments.
