How to Perform Bit Stuffing in Computer Networking?

Answer: Insert an extra ‘0’ after each sequence of five consecutive ‘1’s in the data, ensuring the transmission does not mistakenly trigger a special control sequence.

Bit stuffing in computer networking is a technique for ensuring data integrity and synchronization between sender and receiver:

Define Pattern

A flag sequence like “01111110” marks the start and end of a frame.

Insert Stuffing

Sender inserts an extra “0” bit after five consecutive “1” bits in data, preventing misinterpretation by the receiver.

Receive and Remove

Receiver detects and removes stuffed bits, ensuring correct frame processing.

Error Detection

Helps in error detection; corrupted flag sequences indicate transmission errors.

Usage

Commonly employed in protocols like HDLC and Ethernet for reliable data transfer.

Conclusion

Bit stuffing ensures data integrity and synchronization by inserting and removing specific bits in the data stream according to a predefined pattern. It’s commonly used in network protocols like HDLC (High-Level Data Link Control) and Ethernet.
