<span style="font-family: "Trebuchet MS", sans-serif;"><b>Bit Stuffing</b> is one of the framing technique used in Data-Link Layer (layer 2) of OSI Reference Model.<br />  In Bit-Stuffing technique, stuffing is done at the bit level. It was developed for the once very popular HDLC(High-Level Data Link Layer) protocol. Each frame begins and ends with a special bit pattern 01111110 or 0x7E in hexadecimal. This pattern is a flag byte.</span><br />
