    Dear GATE Aspirants, Any irrelevant/abusive comment will not be tolerated, students doing so will be blocked immediately.

  • Sir in 12th, i guess option B (7, 247) is correct but instead of 247 it should 248 in the answer.

  • (at 28.21 time) since 2nd fragment is re-fragmented into 2packets and MF =1 for both. if last fragment (i.e.140|20) was required to re-fragment (let say re-fragmented into 2 packets) then MF will be 0 or 1?

  • 13 ka 37 fragments ayega…56*36=2016…2020-2016=4B+40header ka b 37th packet banega ….

  • Hello Sir,

    Kindly find the answer to the HW questions:-

    6. 144
    8. 880
    9. 6

    Kindly check the answers, Sir..!

    The best question in this session I would say was question no 7.

    Thank you, Sir..!

  • Ankit sir is Best of Best in computer network….sir aapka crash course itna superb hai…tou fir full course kesa hoga☺️☺️☺️
    Or fir abhyas batch…. humari to parti ho gai…. honestly yesa lagta hai apse computer network padne k bad me forozen ko bhi computer network pada skta hun😂😂😂
    Honestly sir your respect is increasing day by day in my heart….love respect…and salute to you for make everything simple and providing quality content

  • I admire what you do. Too many people think that teaching is an easy profession—because teachers make it look easy! Simply tell a teacher that you recognize how hard their job is. That’s likely enough to make them smile

  • I Don't have a words to describe your strength in computer network….am completely speechless.
    am telling it because this topic was so complex for many students but you made it so simple
    .
    .
    honestly sir love your class million times thanks to teach us computer network

  • H/W ANSWER

    Q6) F.O. VALUE OF 3RD FRAG. = 144
    Q8) T.L. VALUE OF LAST FRAG. = 880
    Q9) NO. OF FRAG. = 6
    Q10) SEQ. NO. OF 1ST BYTE OF PACKET = 800
    Q11) D (DF=1 so, fragmentation is not possible)
    Q12) B
    Q13) TOTAL NO. OF IP FRAG. AFTER FRAGMENTATION = 36

    Sir, 2 hrs ka session hota hai, but time ka pta nahi chalta 🙂🤩😊
