What is real-time?

What is considered real-time? How much latency would be necessary for
it to be no longer real-time? The application is adaptive filtering.
Somebody told me that real-time is strictly one sample in and one
sample out but most of the processors I have met don't work that way
any more - they work on buffers of data and surely all real-time
filters have some latency or is one sample all that is required?
