This video has more content than my whole semester 😂 (6months)

I extremely hate my college lecturer who teaches Computer Network, looking forward to this course.
Loved the DSA bootcamp so far!

for those still debate on how transport and network layer work, understand it by visualizing a road(network layer) and a bus(transport layer) and the people in the bus (packets/information)

Btw thank you for your dedication.🤗

[siriusblack]

I have learnt much much more in this 4 hour video, than I had ever learnt in my 3 year bachelor's degree in computer science.
Keep making such awesome informative content! 🤯

[zb]

I'm an hour in and man Kunal you really are a blessing to the dev/cs community! I've learned java and cs/concepts because you, I'm forever thankful! You explain everything so throughly and simply. Once again, thank you brother!!

Much peace and love!

[jigeeshasur]

I'm in an IIT and this is a crucial resource in my internship prep. Keep up the good work.

[bushranazish]

Was blown away by the content you covered in 4 hours.
The video was interesting and easy.
Kudos to your hard-work Kunal 👏

[vidhijain]

The amount of hard work put in this video, great manh! Recording for 4 hours is not easy guys respect his hard work and be patient for DSA videos. Well explained Kunal 👏 kudos to the effort!

[ADEEBARASHIDBAI]

Just now completed this 4 hours bootcamp. Trust me, he has covered the topics in depth. Loved it. Best for placement purpose.

[GuruTatvaConsultation-ibfb]

Wonderful teaching. You made all diagrams. Cleared all curiosities. Kept the interest intact. You did not hurry up, you gave time to settle down. Perfect teaching. Rare to see good teachers. Thank you

[mayurpai]

How about mastering Computer Networking in just 4 hours? This course is for you. It has been constructed and taught exceptionally well. Unique content on a platform that is second to none. Please keep moving forward, you are an inspiration! ❤️✨

[arctanx]

Everyday 1 hour. It payed off! Thank you so much. I had zero knowledge, I feel now so much more confident about this topic!

[uhvtsww]

I was doing a project about this without even knowing anything about networks, only to have enough grade to pass. So I searched some videos to see if it would be easy and fun to learn this stuff. You made it incredible! Now not only I will be able to get a passing grade but also I learnt a lot about this subject, thank you.

[AnandSharma-kzbs]

Bro, Your work and Content can change one's life, you do what you say ... No any other course may come close to your content

[lilprotakeit]

you covered Programming, Networking and Devops (which is a combination of Networking + OS) but it would be great if you can do OS separately so that non CS guys like me can greatly benefit from this. I really love the fact that you alone are breaking the monopoly of these education mafias .. great .. god bless you and keep it up .. you have many big things to do

[ShivaKumar-stps]

Hi Kunal, really high quality content, just completed till the OSI 7 layers and TCP/IP model, feeling like my own classmates are explaining to me in general. Thank you so much for this amazing course🥲🥲🥲🥲. I stopped regretting missing my University classes after this🤗. Will complete the remaining course. Great learning resource which can be completed in a single weekend. Just disabled my adblocker to support you from now on.

Whenever he takes a pause I started all he said in my mind and brings my curiosity on high best tutorial for Computer networks
