As an Engineering term, Latency refers to the span of time taken from when some action is initiated to when it actually takes effect. In computer networking, Network Latency commonly refers to the round-trip time of a network packet (also known as "ping").

Communication is naturally limited by the speed of light. Therefore the round-trip time of packets is unavoidably linked to the distance over which the packets are being sent, subject to the laws of Relativity. This is particularly an issue in the field of Space Exploration, where the round-trip time of communication is commonly measured in minutes or hours.
