Question:
The following data fragment occurs in the middle of the data stream for which the byte stuffing algorithm is used: A B ESC C ESC FLAG ESC FLAG D. What is the output after stuffing?
The following data fragment occurs in the middle of the data stream for which the byte stuffing algorithm is used: A B ESC C ESC FLAG ESC FLAG D. What is the output after stuffing?
Show Hint
Byte stuffing is used to ensure that control characters like FLAG and ESC within data do not conflict with actual control sequences. It adds an extra ESC character before these special bytes.

- A B ESC ESC C ESC ESC FLAG ESC ESC FLAG D
- A B ESC C ESC ESC FLAG ESC FLAG ESC D
- A B ESC ESC C ESC ESC FLAG ESC FLAG D
- A B ESC ESC C ESC FLAG ESC ESC FLAG D
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Byte stuffing involves adding an ESC byte before every occurrence of a FLAG or an ESC byte to distinguish it from control characters. Final Output After Stuffing: A B ESC ESC C ESC ESC FLAG ESC ESC FLAG D.
