What is Ultra Low Latency?
Ultra Low Latency refers to the minimal delay in the transmission or transfer of data from one point to another. In the context of digital communications, it's the near-instantaneous delivery of data from a sender (like a server) to a receiver (like your computer or mobile device).
This concept is crucial in real-time applications such as online gaming, live broadcasting, and high-frequency trading, where even a millisecond of delay can have significant impacts. For instance, in a live video game, ultra low latency ensures that your actions are registered almost instantly, providing a smooth and seamless gaming experience.
