I/O bound

In computer science, I/O bound refers to a condition in which the time it takes to complete a computation is determined principally by the period spent waiting for input/output operations to be completed, which can be juxtaposed with being CPU bound. This circumstance arises when the rate at which data is requested is slower than the rate it is consumed…
