# Data stream

In connection-oriented communication, a data stream is a sequence of digitally encoded coherent signals (packets of data or data packets) used to transmit or receive information that is in the process of being transmitted.[1]

## Formal definitionEdit

In a formal way, a data stream is any ordered pair ${\displaystyle (s,\Delta )}$  where:

1. ${\displaystyle s}$  is a sequence of tuples and
2. ${\displaystyle \Delta }$  is a sequence of positive real time intervals.
