CC Lab Final Test for 5 A

Logistics:

1. Everyone HAS to be INSIDE the Lab at 9.00am
2. Whoever misses this 9.00am entry WILL NOT be allowed to write the test
3. Every team HAS to bring BOTH their Group A and Group B Projects loaded in their respective laptops.
4. I donot expect it to be deployed on the machines of the Lab
5. Every Student of 5 A writing the test tomorrow WILL have to get a BLANK Blue Book

Conduction of the Test:

• During the first 1.5 hours, that is from 9.15am  to 10.45am, there will be a written test.
• This is the VIVA portion of the test.
• The Project Teams will be asked to sit next to one another.
• Every team member takes a seat in front of a lab computer.
• I will personally make this seating arrangement.
• Every Student is expected to write in his / her individual Blue Book the answers.
• Each team member of a project team will be given a DIFFERENT Question Paper.
• DONOT even ATTEMPT  to copy from your neighbour, because the questions asked to you is entirely different from the question asked to your team member.

Test Question Patterns and Style

1. The question paper will contain TWO generic fundamental questions related to Computer Communication Subject
2. This HAS to be attempted by ALL Students.
3. Here again, these two questions are different for EVERY team member, so you can’t copy!
4. The questions are ALL Subjective. No Objective Type. No Choices.
5. After these two questions, you need to answer ONE Question from Group A Project List of Questions.
6. You need to answer the question pertaining to YOUR Project ONLY.
7. Lastly, there will be ONE Question from Group B Projects. Here again, you need to answer the Question pertaining to YOUR Project ONLY.

Portions to Revise and Come:

1. Port Address, Logical Address, Physical Address.

Comment: I have asked some “fundu” brain-teasers from this. So read this portion.

This is one of the two “generic” questions, wherein the understanding of some fndanemtnal networking

concepts is checked.

You will be able to answer ONLY if you have UNDERSTOOD.

These are NOT Direct Questions. No POINT MUGGING UP…Won’t help!

Clue: Its taken from the list of questions from the back of the Chapter.

2. Standard Organisations

3.  I took some of the questions from your Group Blogs and Presentations Uploaded there.

Comment: Have a good look at what you are “supposed” to have typed on your own!

4. Comparison of the Tools Used for Group A Projects

5. Group B Project —- Study the Psuedocode if it is ARQ project and the method if its Hamming Code / CRC

6. Installation Procedures of Group A Projects and Problems Faced

7. Questions and Answers

8. You should be thorough with your Group B Projects Working and Understanding.

ALL THE BEST!

Announcement

Final Lab internals is postponed to 18th December

Note

We will have Lab internals on 12th December.

Any one in the group may be asked to explain the demo of there projects.

And as usually there will be viva for everyone.

Every group must submit the Feedback before 12th December.

Some Good Problems

1. You are asked to measure the performance of telephone line of bandwidth 4Khz.When the signal is 10V , the noise is 5mV. What is the maximum data rate supported by telephone line?

 

2. A signal travels from point A to point B. At point A, signal power is 100W and at point b, the signal power is 90W.What is the attenuation in decibel?

 

3. Suppose that the signal has twice the power as a noise signal that is added to it. Find the SNR in decibels. Repeat if the signal is 10 times the noise power, 2ⁿ times the noise power, 10^k times the noise power.

 

4. Justify the statement “The maximum achievable modulation rate is twice the bandwidth”.

 

5. We have a channel with a 1MHz bandwidth. The SNR for this channel is 63.What are the appropriate bit rate and signal level?

CCN Question Bank for 1st Internals:

Students should not be under the impression that questions will be compulsorily set from this question bank.

Please compare this question bank with the written copy provided by Maam.

(1)    Explain the functions of application layer, presentation layer, session layer of the OSI model. Give the advantages and the disadvantages of combining these layers into 1 layer in the TCP/IP model.

(2)    The physical address will change from hop to hop but the logical addresses and port addresses usually remain the same. Justify this statement with proper examples.

(3)    Which layer is responsible for moving

1. Frames from one hop to the next.
2. Packets from source to destination host.

Explain the functions of these layers in detail.

(4)    Write if the following is true or false. Justify with suitable diagrams and examples.

1. The network layer gets each packet to the correct computer.
2. The data link layer makes the physical layer appear error free to the upper layer.
3. The transport layer gets the entire message sent to the correct process on the destination computer.

(5)    What is the criteria for a good polynomial generator, find the suitability of the following generators in relation to burst errors of different lengths.

1. x⁶ + 1
2. x¹⁸ + x⁷ + x + 1
3. x³² + x²³ + x⁷ + 1

(6)

1. There are 200 bytes in a data block, each byte being 8 bit. If the error rate is 1*10^-5 what is the probability of the block being received in error.
2. Generate the CRC code for the data word 110101010 using the divisor 10101.

(7)    Let g(x)=x³ + x + 1 consider the info sequence 1001, 110110

1. Find the code word corresponding to the info sequence given above.
2. Suppose the code word has tx error in the first bit, what does the receiver obtain when error checking is done. (Assume MSB error)

(8)    Explain the design of a CRC encoder and CRC decoder. Also give a sample example of the division performed in the encoder and decoder.

(9)    Explain the hardware implementation of the cyclic code in the encoder and the decoder.

(10) If the generator has more than 1 term and the coefficient of x⁰ is 1, all single errors can be caught. Justify the statement with suitable examples.

Interactions Blog

Every Team which  has presented so far, has been asked QUESTIONS.

I want every team to have Two Blog Entries

— Group A Project Q & A Session

—GROUP B Project Q  & A Session

It must record

—The Question(s) asked to your team

—Answers given

—If possible

a) Who asked the question

b) Who gave the answer also

Make this BLog as intersting as possible to read

Deadline for Completion: 12/Oct/2009 for all presentations till date

Please Note: This is an ongoing process till end of semester.
