Today's CS601 Paper
MCQs were mostly from past papers.
(2 Marks Questions)
1) Range of radio communications bands
2) Name of at least four itu-t  protocols
3) Why Addressing bits are added in Asynchronous ARQ and what is the disadvantage of it 
(3 Marks Questions)
1) State disadvantage of step index fiber over graded index.fiber
2) one question about HDLC
(5 Marks Questions)
1) Types of Noise
2) Mechanism of Sliding window with example of n = 8
3) Mechanism of HLDC and name and functions of three frames
4) Two companies A and B want to communicate through radio waves. Discuss about the modes of communication and write about at least two modes 
Rest I don't remember now, but 1 question of two marks is also about HDLC

How much bandwidth for modem is required in case of FSK? [2] Answer: BW required for FSK is equal to the Baud rate of the signal plus the frequency shift. Because of the limitations of voice-grade telephone lines, these modems are restricted to a bandwidth of about 3 kHz 
Question#2 What is R G rating of coaxial cable? Answer:- (Page 126) Different coaxial cable designs are categorized by their Radio government ( RG ) ratings Each cable defined by RG rating is adapted for a specialized function: RG-8
