    ASSIGNMENT 2

    TH
    DEADLINE: 17 JULY 2019
    1. The following character encoding is used in a data link protocol:

    A: 01000111 B: 11100011 FLAG: 01111110 ESC: 11100000


    Show the bit sequence transmitted (in binary) for the four-character frame A B ESC FLAG when
    each of the following framing methods is used:

    (a) Byte count.


    (b) Flag bytes with byte stuffing.
    (c) Starting and ending flag bytes with bit stuffing.

    2. The following data fragment occurs in the middle of a data stream for which the byte stuffing
    algorithm described in the text is used: A B ESC C ESC FLAG FLAG D. What is the output after
    stuffing?
    3. A bit string, 0111101111101111110, needs to be transmitted at the data link layer. What is the
    string actually transmitted after bit stuffing?
