36 Facts About Low Latency

What is Low Latency?

Low latency refers to the minimal delay in data transmission over a network. It's crucial for applications requiring real-time interaction, such as online gaming, video conferencing, and financial trading.

1. Latency is measured in milliseconds (ms), indicating the time it takes for data to travel from one point to another.
2. Ping is a common term used to describe latency, especially in gaming.
3. Round-trip time (RTT) is another term for latency, representing the time for a signal to go to a destination and back.
4. Low latency is essential for high-frequency trading, where milliseconds can mean significant financial gains or losses.
5. Video conferencing relies on low latency to ensure smooth communication without awkward delays.
6. Online gaming requires low latency to provide a seamless experience, reducing lag and improving player performance.
7. Streaming services like Netflix and YouTube benefit from low latency, ensuring quick start times and minimal buffering.
