Week 9 : Programming Assignment 1

Week 9 : Programming Assignment 2

Complete the code segment to catch the exception in the following, if any.

On the occurrence of such an exception, your program should print

§  Please enter valid data

If there is no such exception, it will print the square of the number entered.

Week 9 : Programming Assignment 3

The program given below stores characters in a  byte  array named byte_array, which means ‘A’ is stored as 65.

Your task is the following:

§     Given a user input `n`, print the output in the given format, if `n` = 1,  print:

o     byte_array[1] = ‘P’

§   If the value of n is negative or is out of bound, then use  TRY_CATCH  to print the following:

o     Array index is out of range

Week 9 : Programming Assignment 4

Define a class  Point  with members

§   private double x;

§   private double y;

and methods:

§   public Point(double x, double y){}  // Constructor to create a new point?

§   public double distance(Point p2){} // Function to return the distance of this Point from another Point

Week 9 : Programming Assignment 5

Complete the code below with a catch statement to print the following if the denominator (b) is zero

§   Cannot Divide by ZERO

Week 10 : Programming Assignment 1

Week 10 : Programming Assignment 2

Week 10 : programming assignment 3.

• The  PrintNumbers  class is declared, and it implements the  Runnable  interface. This interface is part of Java's concurrency support and is used to represent a task that can be executed concurrently by a thread.
• Create a constructor of this class that takes two private instance variables (start and end) to represent the range of numbers that will be printed by the thread.
• Create a  run  method that is required by the Runnable interface and contains the code that will be executed when the thread is started. In this case, it should prints odd numbers within the specified range (start to end) using a for loop.
• Hints : Thread.currentThread().getName() returns the name of the currently executing thread, which is useful for identifying which thread is printing the numbers.

Week 10 : Programming Assignment 4

Week 10 : programming assignment 5.

• Use exception handling to handle invalid input temperatures (if  celsius < -273.15 and fahrenheit < -459.67 , program should throw exception error).
• The  TemperatureConverter  class contains two methods for temperature conversion (celsiusToFahrenheit and fahrenheitToCelsius).
• The  TemperatureException  class is a custom exception class that extends Exception and is used to handle invalid temperatures.
• The  TemperatureConverterApp  class is the main class that takes user input for temperatures and handles potential exceptions during the conversion process.
• celsiusToFahrenheit = (celsius * 9 / 5) + 32
• fahrenheitToCelsius = (fahrenheit - 32) * 5 / 9

Programming In Java - Week 9 Feedback Form

Potential additional date (april 28th) for the april 2023 nptel exams.

***THIS IS APPLICABLE ONLY FOR EXAM REGISTERED CANDIDATES*** Dear Student, Greetings from NPTEL! The Jan 2023 session is coming to an end soon and it’s time to put all your best efforts for the certification exam. The NPTEL team has always been there to make your learning process a joyful one and we hope that with your support we will be able to overcome the challenges of conducting a nation-wide exam of this magnitude. With the closure of exam registration form for the NPTEL April 2023 exams, the final registration count stands at 5.1 Lakh compared to 3.7 Lakh reported during the Jul-Dec 2022 semester. Based on the previous semester data, seats at the certification exam centres are booked by NPTEL at the beginning of the exam registration process. As the semester progresses, sometimes these numbers exceed our estimate, especially on certain dates and certain exam cities. Our goal is to allocate the chosen exam cities to all our learners. And by and large, we are able to allocate the chosen cities and dates with active support from our exam partner and our partner colleges. All efforts are being made to allocate the city of choice or the next nearest exam city for the April 29th/30th 2023 exams, as scheduled. However, in view of the unexpectedly large volume of exam registrations & limitation of seats at certain cities on a particular date, we may be compelled to shift the exam date of certain candidates to 28th April 2023 (Friday) as a last resort, only after exhausting all possibilities. We hope that you will appreciate our logistical constraints of such rescheduling and extend all necessary support as before and participate in the exam. With best wishes for the forthcoming exam(s), Warm regards, NPTEL Team

Computer Networks And Internet Protocol - Week 10 Assignment 10 | NPTEL | JAN 2023

Computer networks and internet protocol - week 10 | assignment : answer with explanation.

MAC protocols enable two nodes using their separate communication resources to establish, maintain and terminate a connection.

Which is not one of the llc services.

c. Intermediate switching service The connection mode service provides a reliable, connection-oriented service that uses error control and flow control mechanisms to ensure reliable data delivery. The acknowledged connectionless service provides a reliable, connectionless service that uses error control mechanisms to ensure reliable data delivery. The unacknowledged connectionless service provides an unreliable, connectionless service that does not use error control mechanisms.

Which of the following are correct about asynchronous mac techniques (i) reservation method is suited for streaming voice traffic. (ii) contention method is suitable for continuous traffic..

a. only (i) Reservation – For stream traffic (voice ,bulk file transfer) – Time on the medium is divided into slots, like synchronous TDM – A station whishing to transmit reserves slots for an extended period Con t e n t i on – For bursty traffic (short, sporadic transmissions such as interactive terminal-host traffic) – No control is exercised to determine whose turn it is – Simple to implement and efficient for light loads

Which of the following is true about CSMA/CD? (i) When a collision is detected, the source backs off for a fixed amount of time before retrying for packet transmission. (ii) The worst case delay to detect a collision is equal to the end-to-end propagation delay.

d. None In CSMA/CD (Carrier Sense Multiple Access with Collision Detection), when a collision is detected, the station stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame 1. The worst case delay to detect a collision is equal to twice the end-to-end propagation delay 2.

Every station connected to an Ethernet network is provided a 6-byte physical address by

c. the internet service provider Every station connected to an Ethernet network is provided a 6-byte physical address by the network interface card (NIC). This address is also known as the MAC (Media Access Control) address. NIC fits inside the station and provides the station with a 6-byte physical address.

The T in 10baseT and 100baseT Ethernet technology stands for

b. Twisted Pair The “T” in 10baseT and 100baseT Ethernet technology stands for “Twisted Pair,” which refers to the type of cabling used in these networks.

Which of the following is/are true?

a. In full-duplex switched Ethernet, there is no need for the CSMA/CD method. d. Random backoff in CSMA/CD makes it less probable that sources would try to retransmit in lockstep after a collision is detected. Ethernet is work best under light load. In full-duplex switched Ethernet, there is no need for the CSMA/CD method. In a full-duplex switched Ethernet, each station is connected to the switch via two separate links. Each station or switch can send and receive independently without worrying about collision. Each link is a point-to-point dedicated path between the station and the switch. MAC layer becomes much simpler. In CSMA/CD (Carrier Sense Multiple Access with Collision Detection), a random backoff algorithm is used to schedule re-transmissions after collisions. This algorithm is generally used in Ethernet to schedule re-transmissions after collisions. The random wait time after collision in CSMA/CD is generated using a rule called binary exponential backoff. The purpose of this algorithm is to make it less probable that sources would try to retransmit in lockstep after a collision is detected

In Go-Back-N ARQ, if the sequence number is represented by 4 bits, the sender and receiver window size should be,

d.15,1 windows size = 2^m-1, receiver window size is always 1.

When an acknowledgement is lost duging Go-Back-N ARQ, the receiver retransmits the acknowledgement after a timeout.

According to ieee 802.3, for collision detection the maximum distance between hosts must be within..

a. 500m 10BASE5: Thick wire coaxial cable with a maximum cabling length of 500 meters.

Data Structures and Algorithms Using Python – an NPTEL(Swayam) Exam Experience

Hey Readers….!

Today I want to share my NPTEL exam experience.

Let’s start

Introduction to myself and the exam I took :

I am currently pursuing a Bachelor’s Degree from Sri Padmavati Mahila Visvavidyalayam, Tirupati. I wrote this NPTEL exam when I’m in my fourth semester.

NPTEL stands for National Programme on Technology Enhanced Learning – it is an online certification course for free and it is a project of MHRD initiated by seven Indian Institutes of Technology (Bombay, Delhi, Kanpur, Kharagpur, Madras, Guwahati and Roorkee) along with the Indian Institute of Science, Bangalore in 2003, to provide quality education to anyone interested in learning from the IITs. The goal was to create web and video courses in all major branches of engineering and physical sciences at the undergraduate and postgraduate levels and management courses at the postgraduate level. All courses are completely free to enroll and learn. But if we want certification which shows that we completed the course, we have to pay INR 1000, but this is optional i.e., it completely depends on us whether to write the exam or not. NPTEL provides various courses, among them I took Data Structures and Algorithms using Python.

Exam Pattern :

NPTEL courses are available in 4 weeks, 8weeks, 12weeks also. They provide their courses twice a year.

It consists of Assignments and one online proctored exam. for every week, there will be an assignment, after all the weeks candidate should attempt the online exam. If you select the 8week course they select 6 best assignment scores, or if you select the 12 week course they will select the 8 best assignment scores. Before attempting the online exam, candidates must get the minimum eligibility score from assignments.

The main online proctored exam pattern is as follows :

The exam would contain of total three sections (mostly MCQs) and 25% from assignments and 75% from online exam.

Section I – 2 marks Section II – 2 marks Section III – 2.5 marks or 3 marks Time limit – 3hrs

Preparation Phase :

Firstly I followed the video lectures provided by the NPTEL team, the video lectures are very helpful for me. The professors from IIT’S explained very well. As I have to go to college also, I myself dedicated particular time to prepare for this exam, I dedicated daily 2hrs to prepare for this exam. One thing here is, my seniors told that why you took this course this course is very hard, and I thought like it’s ok, let’s have a try 🙂 .And I started preparing.

Resources I Used:

To prepare for this exam not only listening to the lessons is enough, we must prepare the previous exams question papers also. I searched for some telegram channels which will post the previous exam questions. I started preparing from youtube also, for every week different topics are there, so we need to be updated with every week. I took the notes while following the lectures which helped me for the last minute revision. And also after completing every week they are providing doubts clarification section, from there we can clarify our doubts.

And also as we know that my exam is Data Structures and Algorithms using Python, so I started attempting some moct tests online on Data Structures and Algorithms. I boosted up myself in python also.

Study strategies I followed:

Actually the course I took is eight weeks course, actually I don’t know the importance of this exam, that’s why I didn’t attempted the first 2 weeks assignments. After that my teachers told that it is very important to pass this exam then only you will get credits, then I realised, so it become very complex for me, because I have to score the best in remaining six weeks. Mostly I practiced the assignment questions thoroughly, which helped me to pass the exam. what I want to tell is, just listen to the lectures, clarify your doubts and make your doubts clear and take notes for whatever you learn. Attempt the assignments properly, then you will get good score in assignments.

Taking mock tests helped me to get clarity on the topics.

My experience on the day of the exam :

My exam is in the morning session, and the exam centre is only 3km from my hostel, as I’m staying in the hostel, Me along with my friend went to the exam centre before 2hrs with aadhar card, college id, 2 pens. Actually after I woke up I was in doubt am I able to pass this exam or not, but at the same time, I felt like I prepared well so I can write it well. With that confidence I went to the exam centre.

After going to the exam centre, as usual some verification process like checking identity (either aadhar card or college id), and they had taken my signature and told my exam seating number. The fun fact here is even though it is 2 hrs completed, the exam was not started due to some technical issues, so we are all in relax mood, all our tensions were gone. Actually exam is 9AM to 12PM, but it is started at 11AM.

In that 2hrs I slept in the examination hall for 1hr (^.^) and I revised the concept in my brain for remaining 1hr. And the exam started and I wrote the exam well.

Mostly the questions came from the assignments, that’s why I was able to pass the exam. I attempted mostly all. And I myself kept 30 min to check my answers whether correct or not, so in that 30mins I checked all and completed my session. The fun fact here is except me all my co students gone from the examination hall for first 1hr itself. Only I present in the examination hall for complete 3 hrs. Because I want to utilise time given to me properly.

Challenges I faced during the exam and how I overcame them:

The one challenge that is the most common thing that some nervousness, and it is most common thing for me, but taking deep breath and sitting in a relaxed position can help me from relieving from this. I got some unseen questions during the exam, but I guessed some question by eliminating the irrelevant options.

Results day:

The results came after 3 weeks. And I passed the exam with 53%. It is not an easy task for me to pass in this exam, but I done with it.

Insights I have for future test-takers :

• Some of the insights that I can give to the future test takers are as follows :
• Complete the assignments on time
• Mostly questions come from assignments, so revise the assignments questions and do the model questions also
• Increase your speed of calculations
• Attend mock tests
• Prepare the notes for each topic
• Clarify your doubts in the doubt session

Finally, write your exam with confidence and prepare assignment questions well, and you can got better score than me.
