Byte Stuffing

Byte stuffing. Bit stuffing and unstuffing. The escape characters have a predefined pattern. What is the purpose of bit stuffing and byte stuffing in computer communication.
Byte stuffing is a process that transforms a sequence of data bytes that may contain illegal or reserved values such as packet delimiter into a potentially longer sequence that contains no occurrences of those values. Allows frame to contain arbitrary number of bits and arbitrary character size. Using byte stuffing or other methods to delimit frame start end simplifies the sending and receiving code and reduces memory requirements.
Byte stuffing A byte usually escape characterESC which has a predefined bit pattern is added to the data section of the frame when there is a character with the same pattern as the flag. Char a 20 b 20. Refers to bit oriented hardware.
The frames are separated by separating flag. BYTE STUFFING PROGRAM USING C. DLE STX and DLE ETX The problem occurs when these character patterns occur within the transparent data.
Therefore every time a flag sequence F is encountered it signifies the beginning or end of a frame. Allows frame to contain arbitrary number of bits and arbitrary character size. Startingending bytes byte stuffing 3.
Using physical layer coding violations ie invalid physical codes. Overhead bits are non-data bits that are necessary for transmission usually as part of headers checksums etc. Byte stuffing means adding a special byte to the data section of the frame when there is a character with the same pattern as the _____.
