Low-latency

Definition

Low-latency refers to the minimal delay in the transmission of data or processing of information, ensuring that responses occur almost instantaneously. In various systems, especially those requiring real-time processing, low-latency is crucial for delivering timely results, which can enhance user experiences and increase the efficiency of operations. Applications range from gaming and telecommunications to advanced robotics and artificial intelligence, where even slight delays can significantly impact performance and outcomes.
