Data rate and data transfer rate can refer to several related and overlapping concepts in communications networks:

Achieved rate

[edit]

Capacity

[edit]
  • Bandwidth (computing), the maximum rate of data transfer across a given path
  • Channel capacity, an information-theoretic upper bound on the rate at which data can be reliably transmitted, given noise on a channel
