Thanks! Everyone else only explained how ports are used without getting into what they actually are or how they operate which made it a lot harder to really wrap my head around them. You provided a really great balance of explaining that without getting overly complicated.
Bro literally why can’t anyone else just explain it just as easy as you did ! You made this click instantly ,it felt like everyone else was speaking a completely different language
Thank you so much for the great explanation! The best sentence in this video was "IP address gets the data to the computer, but it's the port number that gets the right application" Wrote it down for myself.
This video made my life so much easier, I just spent a whole semester of just reading and reading and reading, and I literally learned more in this video than the whole semester
sir you are the perfect teacher ever i have seen you giving an every real time example for each topic this makes me practically strong.loved your teaching
Just saw your excellent video explaining TCP UDP and was going to ask if there was one on ports when this auto played haha. Awesome and exactly what I was wanting to know next
I understood the idea of giving a random port to the source because the port is used in the reply. Thanks. Also, I learned some new ports yet I would love to hear from you kore deeply about the 12 famus ports you showed because you did not go over all of them and you did not put enough information in each so I would like to hear more from it. However, wonderful video I learned from you in this video some important concepts and it sharped my knowledge.
Hie thanks for a great review, im attempting to transition fro the construction industry into IT and i go introduced to the cisco skills for all program. I wasnt sure about its value but listening to this review has encouraged me a lot. My goal is cybersecurity and im not sure if i should leave the networking and focus on the security or i should run with both.
The videos from cetbros are really tremendous. The most of the topics the way you explained was awesome. The people will love and start learning who doesn't have idea or interest in Networking !!! . We are really awaiting for more tech videos !!! Appreciate your great works
After running netstat -n and viewing the listed connections, is there a way to find out what each connection is? I would like to know what each of the connections are that are showing on my computer :) Also huge thanks for the incredible and easy to understand content!💙 10/10🙌🏼
If you run netstat -no it will show you the process ID (PID). You can then check the PID in task manager or use the command tasklist. Great to hear you liked the video!
That practice using powercell is so helpfull, i am newbie and i need more practical like this, especially when explaining about tcp/ip model, would like to know what exactly is happening inside the computer during encapsulating and decapsulating data from application layer up to physical layer. Or maybe explain in some 3rd party software like wireshark.
great explanation, my professor doesn't actually teach anything and tells us to just read the material on netacad. Ive been lost since the second week. your videos have helped me get some clarity from what i have been reading.
OMG! That was extremely informative. The person explanation was on point. Even the most stupid Person in the world could understand that intel. Thank you kindly Mr 🙏🏻
Excellent layout, delivery, and explanation of material. Only problem I have is with the british accent, but I struggle with all types of accents. I totally cannot grasp concepts from asian, Indian, arab, french, german, and spanish accents. But I improviced and overcame this by reading the video scripts after the video. This method of learning complex concepts is the best of all methods of learning.
3:27 puse like porque se entiende por qué el navegador web despliega la respuesta del servidor en la ventana correcta (debido al numero random de puerto que se creó cuando se hizo la request... ese mismo puerto usó el servidor para direccionar su respuesta al cliente -computadora donde se está usando el navegador web-) 5:25 uso de netstat -n en el cmd de windows
"wrong": your house address is your IP, your name on the letter is your port because you can have many people living under this address. Or, if instead of house if it is a block of flats: house number is an IP, room number is the port. But then we need also a "sub port number" for the names of people living in this room ;-)
Please correct me if I’m wrong. But my understanding of this is that port numbers are assigned to services or protocols so when we the client reach out to a server, that server knows, because of the port number, which protocol to use while we’re communicating?
Thank you Shubham. Thousands of hosts could connect to the same server on port 80 at the same time. It's the source port and IP address that allows the traffic to be uniquely identified.
Wow, I don’t know why others can’t explain this basic idea clearly. Thank you.
Thanks! Great to hear you liked the video. Thanks for watching!
thanks i got point

@Certbros Sir how can I find port on my window 10 laptop
Letting you know that I passed my CCNA 200-301 this week and your videos helped me do it! Thank you!
Congratulations!! These are the comments I love the most!! Nice work 👍
I just begun my course with cisco so i will be a tier 2 engineer
Thanks!

You provided a really great balance of explaining that without getting overly complicated.
Thank you! My teacher has made port numbers sound like something that one can only understand with multiple doctorates
Thanks Christina! Great to hear the video helped you out. Port numbers are pretty simple once you get your head around it.
LOL. true story!
🤣🤣
🤣🤣🤣🤣🤣 comment is so underrated
Never heard this simple yet comprehensive explanation in any of my computer classes in university.
Thanks for this great video
Yes! Port numbers, came at a a great time. If you guys would make a video on Cryptography or Encryption, it would be too great!
Thanks Ron. Glad the video helped. Good suggestion. I plan on making some security videos in the future. 👍
THANK YOU SO MUCH!!!! I was struggling with Ports but you just explained it so easily. Thanks again 🙏 💕
You're welcome! Great to hear it helped 👍Let me know if you have any questions.

I've been in IT for 20 years and I still learned something from this.
Never did get my ccna certificate, i just had to learn as I went after college
Me too been in IT for 24 years and I still learned something from this.
Just saw your excellent video explaining TCP UDP and was going to ask if there was one on ports when this auto played haha. Awesome and exactly what I was wanting to know next
Great to hear! IP Addresses next 👍
These videos have really helped me wrap my head around so many networking concepts
Best video for this concept in the whole UA-cam.....love you guys❤️
Thank you, your video took the confusion out of understanding what Ports are and how they work.
Thanks Denise! Great to hear it helped.
OMG!!
Some tutorials are just too short but they explained everything you're looking for
Thank you very much
Thank you Ibrahim! Really great to hear you liked the video.
Good luck with everything.
could you please do an updated tutorial about STP ?
btw great way of explaining new concepts to beginners !!
Thanks Amen! I appreciate the support.
STP will be updated in the full course. It will have the same information it will just look and sound better.
@@Certbros Looking forward to it

very crisp and spot-on, love your videos. Could you please make a video on Virtualization.
Thanks! Great to hear you liked it. Yes, virtualization is on my to-do list 👍
Wow. Brilliantly explained
Great work... Loved it ❤️

Excellent explanation!
Thanks!
This was so helpful!! Thank you
Thank you! Helped me so muc with my homework
Great video. but at 7:10 I think you meant the CLIENT is not sending the request to the web application port, not the SERVER.
You're a life saver..
Your welcome 🙏
I f'ing love CertBros!
Thanks for the explanation that's so helpful ❤️

Port 80 is my favorite 😂
great explanation, thanks for such good content
Please correct me if I’m wrong. But my understanding of this is that port numbers are assigned to services or protocols so when we the client reach out to a server, that server knows, because of the port number, which protocol to use while we’re communicating?
Great Explanation !!
awesome man ...keep going
Thank you!
Learning now for my CCNA cert
Amazing videos and thanks for had shared with us
Thanks Jaime! No problem, glad you liked it.
Great tutorial......just one question, what if multiple host are requesting connection for port 80 ?? how multiple host will connect to that server?
Thank you Shubham. Thousands of hosts could connect to the same server on port 80 at the same time. It's the source port and IP address that allows the traffic to be uniquely identified.
@@Certbros Thank you, appreciate your quick response !
very good video,which programm you use at timeline 4:32?
made it so simple, thanks
Awesome video amigo , thank you 🙏🏼🙏🏼🙏🏼🙏🏼
