The insertion of extra bits into a data stream to avoid the appearance of unintended control sequences that may interfere with a data frame.

Insertion of additonal bits in a plesiochronous data stream to compensate for differences in the nominal transmissions rate.

Insertion of additional bits in a Plesiochronous data stream to compensate for differences in the nominal transmission rates.

A process in bit-oriented protocols where a zero is inserted into a string of ones by the sender to prevent the receiver from interpreting valid user data (the string of ones) as control characters (a Flag character for instance).

In data transmission and telecommunication, bit stuffing (also known -- uncommonly -- as positive justification) is the insertion of noninformation bits into data. Stuffed bits should not be confused with overhead bits.
