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

Today my paper

(1)why we use guard bands in FDM?

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
• Used in Thick Ethernet
RG-9
• Used in Thick Ethernet
RG-11
• Used in Thick Ethernet
RG-58
• Used in Thin Ethernet
RG-59

Line of Sight Propagation

 

NAK: Error or start of transmission

 

Write all steps of checksum method. [3] Answer: (Page 179)

o The sender subdivides data units into equal segments of ‘n’ bits(16 bits)

o These segments are added together using one’s complement

 o The total (sum) is then complemented and appended to the end of the original data unit as redundancy bits called CHECKSUM

 o The extended data unit is transmitted across the network

 o The receiver subdivides data unit as above and adds all segments together and complement the result

 o If the intended data unit is intact, total value found by adding the data segments and the checksum field should be zero o If the result is not zero, the packet contains an error & the receiver rejects it

 

 

 

Channels must be separated by strips of unused BW (guard bands) to prevent signals from Overlapping

 

 

 

What are the two major classes of synchronous protocols at data link layer?     2 Answer: (Page 206)

Character – Oriented Protocols

 Bit – Oriented Protocols   

 

in Poll/select method why addressing is necessary?

For the primary device in a multipoint topology to be able to identify and communicate with a specific secondary device, there must be some addressing convention,,

 

For this reason, every device on the link has an address that can be used for

Identification

 

Advantages of ENQ/ACK?

 

(6)briefly explain stop and wait method?

In this method, the sender waits for an ACK after every frame it sends

194 Only when an ACK has been received, is the next frame sent

 

o This process of alternately sending and waiting repeats until the sender transmits an EOT frame

 

Example: Officer giving dictation to the Typist, He says a word, typist says OK, he says the next word, typist says OK and so on

 

 

 

 

1) Which type of device used for connect a terminal to a T-line

2) What should b the relationship between the size of thr crc remainder and divisor

3)Two employee in 2 diff companies suggest device to connect each other

4)Physical specification on which RG rating of coxial cable are defined

5) EM spectrum is divided into several call bands just write the complete name of 6 of those range

6) why do we need to have address bit in Asynchronous time division multiplaxing ? and disadvantages of using address bit in it..

7) consider a net work topology based on poll\selective procedure where on device is designed as primary other device is secondary.. you mention two possibilities to terminated data transmission

Yeh 7 question hi aye the Slip ki back pe.. Page hi khatam ho gaya

Aik question b past papers ya currents papers jo yahan share hn in ma se nai tha..

Jo meri tarah past papers se tyari krta wo to gaya..So sub handouts kro tyari

Aik achi baat bus mcqs 40% moaz wali file se the wo b age peche kr diye howe the...

Bara muskil Paper tha...

Best of luck 

 

anyone solve 2014 cs601 paper and upload, sir Tariq malik please solve the above paper and upload please, Thanks for sharing
