In digital systems, what does 'latency' specifically refer to?

Latency in digital systems specifically refers to the delay encountered from the moment data is captured until it is processed or displayed. This concept is crucial in understanding the efficiency and responsiveness of a digital system. High latency can result in noticeable delays, which may impact the user experience, especially in real-time applications where timely processing is critical.

In contrast, the speed of data transmission pertains to the rate at which data is sent across a network or between devices, which is a different concept from latency. The accuracy of data representation focuses on how precisely the data reflects the intended information, and while it is important for data integrity, it does not relate to the timing of processing. Lastly, the overall system performance rating encompasses a wide range of factors including speed, accuracy, and latency, but it does not specifically define the delay aspect that latency highlights. Therefore, the definition centered on the delay from data capture to processing or display is the most accurate interpretation of latency in digital systems.
