Q 01: (a): Information today comes in different forms. Explain those forms with the help of examples in context of data communication. (b): Analog-to-analog conversion, or analog modulation, is the representation of analog information by an analog signal. Then why we need to modulate an analog signal; when it is already analog?

Q 02:
(a): What do you mean by communication protocol? List commonly used protocols with its function.
(b): Is it possible to design a single protocol which handles all problems occurred during data communication? If yes, then how?
Q 03:
(a): A bit stream 1011000 is transmitted using the standard CRC method. The divisor is 1011. What is the actual bit string transmitted? Also find out whether, there is an error or not?
