​KembaraXtra-Computer Terms – bit stuffing:
Bit stuffing is a technique used in data communication where additional bits are inserted into a stream of transmitted data. This method ensures that specific bit patterns used for control purposes do not accidentally appear within the actual data being transmitted.
For example, in communication protocols such as HDLC, SDLC, and X.25, a sequence of six consecutive ones is reserved to mark the beginning or end of a data frame. To prevent this sequence from appearing inside the data itself, the system automatically inserts a zero after every sequence of five ones. The receiving system later removes these inserted bits to restore the original data.
