Overview of data latency
- [Narrator] So far we've been using the term information and data interchangeably. That's because computer data is any kind of information. A home location, a patient's vital statistics, such as the actual reading of the heart rate, blood pressure, and body temperature, are all examples of data. Now latency means delay. In computing, low latency is little to no delay for data to be available to and from a computer or device. Another way to say it is that latency is the time needed to compute and transfer data between two points. Data latency can also apply to how long it takes to send or receive information to and from a device or system. For example, once a patient's abnormal heart rate is read, the time between reading, detecting, and notifying a healthcare worker is the total latency. Edge computing data latency is impacted by several factors, such as where the data is located, the edge or the computer's resources, such…
