Ethernet framing reserves the bit pattern 0111110 (0x7E) as a flag to mark the beginning and end of a frame. We use bit stuffing to prevent this 7E pattern from occurring in data. This modifies the data (the bit stream) so that the pattern doesn't occur. * Why do we use flags to mark the beginning and end of a frame? * Describe the algorithm to "bit stuff" a data stream. * Describe the algorithm to restore the original stream. * For the following bit stream, show the data stream after framing and bit stuffing.
