Lag time
The lag time was the time difference between a query made of a computer and the answer.

In 2151, Hoshi Sato explained to Jonathan Archer that she would rather remain on  and use the linguistic database, relaying translations over the comm than "tie (her) universal translator into the database through the comm" (as Archer put it), because the lag time would triple. Archer then said he didn't mind waiting a few seconds if it meant she would be available in person. ()
