Oh Bhai😂 I m in my first sem and I love this content already. I just can't wait for him to do something bigger. Every step of his is new records, I really appreciate it.
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!
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! 🤯
fun fact: Tata is responsible for over 130,000 miles of fiber cables under the sea and 400 PoPs, connecting more than 240 countries and territories around the world. Tata equips 1 million square feet of data center and collocation space worldwide. Which is 24% of all around the world.

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!
@JaitraSaketh-jf3if I learned it by my own, just to get into the topic of devops. It's a great introduction into networks and helps to understand how information flows through the internet
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)
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
I learnt all these in my college subject called DCN but i never got a clear picture of how the data flows. I always had some confusions and doubts. I have no words to thank you for the efforts you make to explain it clearly. The only youtuber I blindly trust without any second thought. Glad I came to know about your channel. Wish you reach more heights and get recognized for your hard work.
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! ❤️✨
is it good for placement puporse for a non-cs student, did he miss anything or left anytopics just by saying type in google like that because i saw some comments like this.
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
Man this is an exhaustive course on computer networking. This is an awesome intro for someone who wants to skip their professors classes and get dirty with overall concepts. Please check the whole video. More detailed reading on various topics will be needed even if you complete this 4hr video. Though this will serve as a good starting point. I learnt this over couple of days and many pages of notes. I will compile my notes and if possible share it here once done. Thanks Kunal for this awesome course.

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.

Thanks kunal like yesterday i have zero knowledge about computer networking and today i am feeling very confident that i know everything. Thank you this video has a lot of information than my whole semester.
it was awesome till you said MAC address keep on changing. Took me some time to research and get it clarified. for those who didn't understood it here is the explanation. A MAC (Media Access Control) address is a unique identifier assigned to a network interface of a device, such as an Ethernet card or a Wi-Fi adapter. It is used to identify the device on a local network and is usually assigned by the manufacturer. As a data packet travels from one device to another, the MAC address of the source device remains the same, it is the destination MAC address that changes. The destination MAC address is the MAC address of the next hop device, it is the device to which the data packet is sent next. When a data packet is sent by a device, the device adds the destination MAC address to the packet's header. As the packet travels through the network, each network device that receives the packet examines the destination MAC address in the packet's header to determine if it is the intended recipient. If the device is not the intended recipient, it examines the IP address in the packet's header and uses routing tables and algorithms to determine the next hop, the next device to which the packet should be sent. The device then changes the destination MAC address in the packet's header to the MAC address of the next hop device and forwards the packet. In summary, as a data packet travels from one device to another, the MAC address of the source device remains the same, it is the destination MAC address that changes. Each network device that receives the packet examines the destination MAC address in the packet's header to determine if it is the intended recipient, if not it uses routing tables and algorithms to determine the next hop, the next device to which the packet should be sent, and changes the destination MAC address in the packet's header to the MAC address of the next hop device and forwards the packet. Basically when your data packet is on global network it has global IP addresses. which router will look to get the next hop's MAC address. when you are on private network we use private IP address to get the next hop's MAC address. both the cases we find the MAC address from routing tables. Note that routing tables in global network is different from routing tables in private network. Say we are connected using wifi to a private local network before the last hop the last before node will load the MAC address our PC's wifi and send it to our PC. It will get that MAC address again from routing table.
Did you mean each device which receives the frame will check the destination IP address to see if it's the intended destination because the frame is hopped to the next device having the MAC address right so it is the intended destination according to MAC address in the header.
I am sure this explanation is not right. Both source and destination mac address change at every hop. only ip address is constant. at every hop the destination mac is changed to the MAC of the device further along the path and the source to the mac of the current transmitter of the packet. Please correct me if I am wrong, since logically it does not make sense for source MACs to be constant as acknowledgments and similar protocol specific activities are done between the network segments. The immediate source is also required for the dynamic learning of the Mac Table for each intermittent device so it does not make sense for source MAC to be constant.
One suggestion!! Study more on DNS, transport layer and TCP/IP, whatever Kunal has taught is good, but you need in-depth knowledge of the above topics to understand networking properly.
This video is very very explicit. Kunal has really broken down networking and I can clearly understand how the internet works. My college lecturers did a very poor job on this subject. Thank you so much Kunal.
Placements are going on in my college rn and I had 0 knowledge of Computer Networks so far. I have learned a lot from this single video and am now confident enough to face questions on this topic in my interviews. Thank you!
Kunal its a humble request to you. Please make a brief video on Operating System. Your teaching is always on point. I hope you'll read my comment one day. Love from West Bengal ❤

Thank you for this amazing crash course for computer networking. It has help me understand and recall those networking concepts that I have learnt in my diploma. I have completed this video within 7 hours also jotted the notes that were important especially OSI models and how the OSI models works in the networking. I wish you achieve a lot of success in whatever you're doing for the IT community around the world. Hope you're having a good week ahead. 🙃😉
Just finished this masterpiece , Its really amazing Kunal ...Looking forward to more DevOps Tutorials very soon..but I have one doubt as its a total theory and very difficult to remember all the terms always in your mind. Please make a summary note, I know you told in the video that make your own notes, but short summary notes will be much appreciated. Thanks brother 🥰
I am pretty satisfied with this course . It covered almost everything but the only problem was did not go much in detail but it is fine because i am pretty sure if this was a longer video.... i would be demotivated to even start the course. I did look into everything and understood in detail and loved how you related it to the real world which made it much more understandable. Understood reality from you theory from the internet .
Developed a special interest on CN after completion of this 4 hr course... The way you explained the topics is simply awesome🙌 Thank you so much for this awsome lecture course ✨✨🙇♀
Hey! Kunal.. Your content is awesome 🙂 And I request you to add notes or screenshot of the pages in drive or pdf format by which we can revise the things forgetten in the future...... Please add in the description of the video.... How many of you want this???
Thanks Kunal. This was a much awaited one course by you. I was thinking of switching the career in DevOps but didn't find out the resources a s a whole at once place and in a systemic way. Saw your whole syllabus for this course and it covers almost everything from basics to mastery. Thanks a bunch bro
if there is a word that is supreme of all the appreciation words, I think he deserves it. only goosebumps for your knowledge brooo you are an inspiration!!!
I knew all this before watching this because I used to watch network chuck videos about hacking and it was just for fun but this is refreshing with an Indian guy explaining.
🥺🥺 such a awesome course at zero prize is a blessing for us. Thank you bhaiye for it. It really helping us a lot. Your DSA playlist is of next Lvl and I believe this will going to be more high quality than it. Bhaiya It will also be much helpfull if u will tell us more about remote job opportunity.
Thank you Kunal for such an amazing video ! Never thought learning computer network will be such a fun.When I am making notes from ur video I feel like writing each and every word because everything you say is important and valuable on the topic, it's never time wasting or not useful .I am blessed to have you as a teacher.Thanks a lot !!
This is really helpful kunal. I am currently doing your dsa bootcamp and it is actually wonderful the assignments you provide for practice. I have just finished arrays(the initial few videos) and i am really getting a deep understanding about dsa via your videos and the leetcode questions you provide for practice. Hope i am able to stay consistent with all this quality content you are providing us with . Also very excited to pursue this devops bootcamp alongside with java dsa. Also i feel the dsa course u provided can be best utilized if we r consistent with solving assignments as soon as we finish a topic.I intend to do it with my own pace and also love the quality of content you provide for us for free. Keep it up and thanks a lot for this.
I don't even know what networking is, started watching your videos making me feel like a network engineer bhai. Awesome interaction while explaining the concepts. That pause gives diff vibe
Thanks alot !!! This course helped me revise and strengthen my computer network concepts. Highly recommended for revision before your placement or job interviews. Greatly appreciate the huge amount of effort and hours you put to create such valuable content. Thanks again!
Just started 20 mins ago , so far - bhaiya deeply explaining basis - pretty impressed with the quality. I'll pin here after completing of thjs course. Thank you community
whole video he be like "we will discuss it later in detail" and then he never discuss it in detail, he is just going without any proper flow, picking random topics and sometimes just reading some notes without proper explanation.

it was awesome till you said MAC address keep on changing. Took me some time to research and get it clarified. for those who didn't understood it here is the explanation.
A MAC (Media Access Control) address is a unique identifier assigned to a network interface of a device, such as an Ethernet card or a Wi-Fi adapter. It is used to identify the device on a local network and is usually assigned by the manufacturer.
As a data packet travels from one device to another, the MAC address of the source device remains the same, it is the destination MAC address that changes. The destination MAC address is the MAC address of the next hop device, it is the device to which the data packet is sent next.
When a data packet is sent by a device, the device adds the destination MAC address to the packet's header. As the packet travels through the network, each network device that receives the packet examines the destination MAC address in the packet's header to determine if it is the intended recipient.
If the device is not the intended recipient, it examines the IP address in the packet's header and uses routing tables and algorithms to determine the next hop, the next device to which the packet should be sent. The device then changes the destination MAC address in the packet's header to the MAC address of the next hop device and forwards the packet.
In summary, as a data packet travels from one device to another, the MAC address of the source device remains the same, it is the destination MAC address that changes. Each network device that receives the packet examines the destination MAC address in the packet's header to determine if it is the intended recipient, if not it uses routing tables and algorithms to determine the next hop, the next device to which the packet should be sent, and changes the destination MAC address in the packet's header to the MAC address of the next hop device and forwards the packet.
Basically when your data packet is on global network it has global IP addresses. which router will look to get the next hop's MAC address. when you are on private network we use private IP address to get the next hop's MAC address. both the cases we find the MAC address from routing tables. Note that routing tables in global network is different from routing tables in private network.
Say we are connected using wifi to a private local network before the last hop the last before node will load the MAC address our PC's wifi and send it to our PC. It will get that MAC address again from routing table.
Did you mean each device which receives the frame will check the destination IP address to see if it's the intended destination because the frame is hopped to the next device having the MAC address right so it is the intended destination according to MAC address in the header.
I am sure this explanation is not right. Both source and destination mac address change at every hop. only ip address is constant. at every hop the destination mac is changed to the MAC of the device further along the path and the source to the mac of the current transmitter of the packet. Please correct me if I am wrong, since logically it does not make sense for source MACs to be constant as acknowledgments and similar protocol specific activities are done between the network segments. The immediate source is also required for the dynamic learning of the Mac Table for each intermittent device so it does not make sense for source MAC to be constant.
One suggestion!! Study more on DNS, transport layer and TCP/IP, whatever Kunal has taught is good, but you need in-depth knowledge of the above topics to understand networking properly.
Much beneficial to crack HR round in computer networking. Thank you Bro. Keep it up 😊😊
Is this Computer Network playlist complete for interview preparation?
@@softprob2838 did you get an answer?
This video is very very explicit. Kunal has really broken down networking and I can clearly understand how the internet works. My college lecturers did a very poor job on this subject. Thank you so much Kunal.
It took me 2 weeks to complete this video because I'm from non IT background. Lovely video I got much idea about computer network. thank you.
Placements are going on in my college rn and I had 0 knowledge of Computer Networks so far. I have learned a lot from this single video and am now confident enough to face questions on this topic in my interviews. Thank you!
Update: got placed as an SRE in a reputed company with a decent package :)
Cheers mate
Is this video enough for my CN interview preparation? Please reply 🙄
Kunal its a humble request to you. Please make a brief video on Operating System. Your teaching is always on point. I hope you'll read my comment one day. Love from West Bengal ❤
Sure I will
Yes Kunal it will be kind of you if you make a video on OS . You are the best teacher.
I would also love that

4 days of continues learning had a good result . thanks kk and lets have this Devops bootcamp the best .
One of the few clear networking explanations available on UA-cam thanks a lot 👍
Completed in one go 🔥🔥🔥💯💯 highly appreciated your efforts
Took me 5 days to complete (with notes).
Looking forward for new lectures.
Keep up the great work Kunal 👍
Can you provide us the notes:?
can you share the link of notes?
Please share your notes
yeah even I need notes
Please share the notes.
This is a jackpot for people who are beginners and who are trying to re-fresh on this subject!
Thanks a lot! :)
Is this video enough for my CN interview preparation? Please reply 🙄
What an in-depth dive into the internet, worth these 4 hours.
Thanks a-lot Kunal!
Thank you for this amazing crash course for computer networking. It has help me understand and recall those networking concepts that I have learnt in my diploma. I have completed this video within 7 hours also jotted the notes that were important especially OSI models and how the OSI models works in the networking.
I wish you achieve a lot of success in whatever you're doing for the IT community around the world. Hope you're having a good week ahead. 🙃😉
Just finished this masterpiece , Its really amazing Kunal ...Looking forward to more DevOps Tutorials very soon..but I have one doubt as its a total theory and very difficult to remember all the terms always in your mind. Please make a summary note, I know you told in the video that make your own notes, but short summary notes will be much appreciated. Thanks brother 🥰
haan bhai. sab kuch wahi kar dega. tu bas video dekh. padhiyo mat.
Wow man it's 4hr video , think about days it took to make this great video man. Great job
2 days
@@KunalKushwaha moye moye
Thanks for this course Kunal.
You're letting students get exposure of several technologies♥️
I couldn't appreciate enough for this. Your teaching manner is so nice that every concepts get without hurdles and like a Laminar flow.
I am pretty satisfied with this course . It covered almost everything but the only problem was did not go much in detail but it is fine because i am pretty sure if this was a longer video.... i would be demotivated to even start the course. I did look into everything and understood in detail and loved how you related it to the real world which made it much more understandable. Understood reality from you theory from the internet .
Developed a special interest on CN after completion of this 4 hr course...
The way you explained the topics is simply awesome🙌
Thank you so much for this awsome lecture course ✨✨🙇♀
Hey! Kunal..
Your content is awesome 🙂
And I request you to add notes or screenshot of the pages in drive or pdf format by which we can revise the things forgetten in the future......
Please add in the description of the video....
How many of you want this???
Thanks Kunal. This was a much awaited one course by you. I was thinking of switching the career in DevOps but didn't find out the resources a s a whole at once place and in a systemic way. Saw your whole syllabus for this course and it covers almost everything from basics to mastery.
Thanks a bunch bro
literally in just 2 days i became admirer of this guy and his unbelievable potential
Started my journey on cybersecurity and I never really understood Networking until I found this video. Thanks a lot
Very usefull session. Excellent explanation.
Even we can understand by setting the playback speed by 1.5 which saves lot of time.
Just completed the Computer Networking Course. Really blown away by the content you covered in 4 hours. Thank you for giving us such awesome content.
Is this Computer Network playlist complete for interview preparation?
If anyone wants notes pdf,I have it. Giving it for rs 50.
have you made the notes of CN, please share it if you made
@@nickranjan8206 I want
@@nickranjan8206 ye krle tu pehle , vha kunal bhaiya free me pdha rhe aur tu notes bhi nhi de skta
if there is a word that is supreme of all the appreciation words, I think he deserves it. only goosebumps for your knowledge brooo you are an inspiration!!!
I knew all this before watching this because I used to watch network chuck videos about hacking and it was just for fun but this is refreshing with an Indian guy explaining.
🥺🥺 such a awesome course at zero prize is a blessing for us. Thank you bhaiye for it. It really helping us a lot. Your DSA playlist is of next Lvl and I believe this will going to be more high quality than it. Bhaiya It will also be much helpfull if u will tell us more about remote job opportunity.
Thank you Kunal for such an amazing video ! Never thought learning computer network will be such a fun.When I am making notes from ur video I feel like writing each and every word because everything you say is important and valuable on the topic, it's never time wasting or not useful .I am blessed to have you as a teacher.Thanks a lot !!
please can you share your notes
Please can you share your notes. I have an exam coming up and need it
enjoyed the full course and learned a lot of complex things in a very simple ways . Thanks Kunal
This tutorial made me to love the computer network subject. Truely it gave complete practical knowledge about the subject. Thank you so much Kunal
One of the best CN videos I hv watched so far.
Thank you so much Sir.
it is like entire sixth semester of engineering computer network summarized in four hours, wish they explained to me this good in engineering college
No Computer Networking course could match this level 🚀
Hit like if you want Kunal to finish this bootcamp in less than 3 months...
Kunal Sir, you are literally one of the most genuine social media influencers of India..hats off
i completed ds bootcamp now coming to watch network kunal the best teacher ever....
This is really helpful kunal. I am currently doing your dsa bootcamp and it is actually wonderful the assignments you provide for practice. I have just finished arrays(the initial few videos) and i am really getting a deep understanding about dsa via your videos and the leetcode questions you provide for practice. Hope i am able to stay consistent with all this quality content you are providing us with . Also very excited to pursue this devops bootcamp alongside with java dsa. Also i feel the dsa course u provided can be best utilized if we r consistent with solving assignments as soon as we finish a topic.I intend to do it with my own pace and also love the quality of content you provide for us for free. Keep it up and thanks a lot for this.
Just finished this fantastic concise lecture. Pretty crucial for headstarting my DevOps career.

Thanks Kunal for creating such a amazing educational content for us ✨ Huge respect to you from my bottom of heart.
whole video he be like "we will discuss it later in detail" and then he never discuss it in detail, he is just going without any proper flow, picking random topics and sometimes just reading some notes without proper explanation.
