The purpose of bit stuffing is used as a delimiter to mark the end of one frame and the beginning of the next frame.
<h3>What is Bit Stuffing?</h3>
This refers to the use of one or more information bits in order to break up the message for easy synchronization.
The parts of a frame are:
- Frame header
- Payload field
- Trailer
- Flags.
<h3>What is a Flag?</h3>
This is a bit pattern that is used to define the start and end bits in a given frame and the 8-bit pattern 01111110 as the flag is commonly used.
Hence, we can see that your question is incomplete so I gave you a general overview to help you have a better understanding of the concept.
