In a data link protocol, two dedicated bytes are used: FLAG$=01111110$ and

ESC$=10111110.$ Consider two data bytes A$=11001011$ and B$=11101001.$ Assume the four$-$

character data frame $\{$ESC A B FLAG$\}$ is to be transmitted.

a$)$ Write the bit sequence transmitted $($in binary$)$ if the framing method is starting and

ending Flag bytes, with bit stuffing.

b$)$ Write the byte sequence transmitted and the corresponding bit sequence if the framing

method is starting and ending Flag bytes, with byte stuffing
