You have a gift for conveying information so clear and understandable than any professional or paid class. I'm pretty sure you've kickstarted a lot of careers with your content. Thanks!

Wow...thanks Pascal!

That was so Kind and nice!!!

God Blaise Pascal.. I mean God bless Pascal

[@LecheSeason1]

That was very kind of you bro!!

[@xNeuker]

He sure has.

I think it's a great idea how this video started, by separating ports from physical connections and then defining them the right way a lot of confusion can be avoided especially for beginners.

[@leopold3146]

It would be better to start with explaining the networking layers. From this video, it is not clear how network devices decide which of the network protocol to use. In turn, ports are just a feature of the protocols based on IP whilst IP is far not the only protocol existing.

[@toby9999]

@@leopold3146 That would be for a more advanced video. Even this one was confusing enough.

[@ninsuhnrey]

@@leopold3146 Thank God, this channel is the literal antithesis of whatever it is you just wrote. I'm a novice, currently just enjoying learning the foundational stuff, and was deciding whether to group and watch this video under hardware. That opening - and the video - was solid gold. If everything were to be explained as clearly as this channel can, I swear there would be world peace.

[@sonnyinaz]

See my post above you.

[@mxolisindlovu9194]

very true i used to think ports are actual stuff i can touch on a PC but this videos makes it super easy

[@GoPlayMLP]

As someone who works in "semi-IT" and hasn't been trained on this, your videos are a godsend. Thank you so much for every single video!

[@LibraryOfParadise]

I must say thank you. Your channel did more than help me past some tests. Your videos helped me land a job in the field. I was in professor messers chat room the other day and multiple people told me no need to understand the TCP/IP model because it's not on the Comptia Objectives. Yet it was one of the first few questions in the job interview. Need to be extra careful who we get information from. They also asked about VLANs and Subnetting which I both learned from your channel as well as converting decimal and IP addresses into binary.

[@richardhyman6981]

I have been studying for my Network+ exam for about four months and your videos have been indispensable in helping to understand basic concepts or confirming what I thought I understood. Thank you and please keep putting this content out there!

[@v-force1379]

Did you pass? Because I too am studying for Network+

[@richardhyman6981]

@@v-force1379 I did pass. The hardest part for me was the practical questions but if you take your time and try to break the practical into pieces it is not so intimidating and you can figure them out. Good luck! You’ll do great I’m sure!

[@LaMelinette]

I've been studying for a career change in IT and have just found your videos! THEY ARE SO MUCH CLEARER than my actual course and I've had a couple of lightbulb moments where things have just clicked. So thank you very much

[@deadseamonster]

Probably the most effective, yet, streamlined explanation of port numbers that I've seen. Sooo many people have trouble grasping port numbers. I'll be sharing this video . Thanks!

[@toby9999]

Yeah, I'm having trouble grasping anything to do with networks. The whole thing is horrendously complex and unintuitive.

[@isuckatthisgame]

​@@toby9999 Same. And I'm student of ICT LOL :D

[@mellord83]

​@@toby9999 I think once you understand subnetting and the basics of networks, it will become much clearer. I was the same as you

[@utubegenac17]

I’ve worked in IT for 30 years and this is the best explanation of ports I’ve ever had. Thanks for making this video.

[@hosaneg9962]

Left Medical Came to my passion One of the motivations was your videos Because you just make it so easy. MashAllah May Allah bless you Ameen

[@solaceinthegallows7068]

Ive worked as a cable tech and now I am a fiber tech for an ISP and these videos are super helpful in learning the intangible side of networking. Thank you!

[@CutcliffePaul]

This video explains network ports pretty well. But I always like the analogy of IP address being like phone numbers and port numbers being like extension numbers: you call the phone number (IP address) to connect to the switchboard then provide the extension number (port number) to reach the person you want to call.

[@venkatceh1072]

Your Explanation was also very clear, thanks for conveying information in a different way.

[@mother8304]

love this

[@pApAkAnCHa214]

This was by far the best content I found on KZbin on Ports, thank you for posting sir, the way you breakdown complex topics is phenomenal. You are helping thousands of people from your content, thanks for putting visuals, they are indeed very helpful to understand. God bless you. Love and respect from India.

[@teomcam]

Teaching this way in detail and also preparing these animations must be intense work. Thank you so much sir, you are certainly a genuine legend.

[@PowerCertAnimatedVideos]

Thanks. Yeah, it's a lot of work.

[@legodude05]

Your videos are amazing. I think the animations are super helpful because a lot of the time when this stuff was introduced to me it was through a bunch of definitions, and I would often times try to just memorize them. However, with the images you can just remember the picture and then when asked to explain the concept itself, you can explain what you are seeing or saw rather than a explaining a bunch of technical jargon.

[@rafaelavila9]

Powercert, you’ve helped me understand so much about networking. I’ve upgraded my whole house thanks to you

[@glewfw7989]

this channel is a bless.. its literally a 2k cisco class but better explained

[@nycupofjoe497]

I’m going to get an IT job simply based on this channel. Well explained information and very thankful for it.

[@ThisCanNotBTheFuture]

It's worth adding that the limitation of 65,535 ports has nothing to do with memory or OS constraints, but rather merely reflects the fact that the TCP protocol allows only 16 bits which can be used to encode a port number.

[@disrael2101]

I didn't get the second reserved list of ports that companies can own from 1000~ til 40000~.. what is that about and why is it needed? Also can I use port 80 for ftp on my computer in theory?

[@tacorito1809]

@@disrael2101 no, you cant use ftp in port 80 because you use it for http. why its limited to 40000 i have no idea. gotta ask ICANN i guess. edit: A registered port is a network port designated for use with a certain protocol or application. Registered ports-Ports in the range 1024 to 49151 are not assigned or controlled, but can be registered to prevent duplication.

[@iamwisdomsky]

@@tacorito1809 technically speaking, no one is stopping you from using an another type of service on a port just like how you can run a web server on a port that's not port 80. It's just about standards. The standard is to use port 80 when running a web server but you can still use an another port if you want and you will still be able to access that web server via wget/curl or your browser by specifying the port. Same is also true for ftp servers, as you will notice, most modern GUI FTP clients have port field where you can enter a specific port in case the ftp server is running on an another port (not port 21).

[@tacorito1809]

@@iamwisdomsky hmm, interesting. would there be any drawbacks from not applying the standard?

[@yichaohan6317]

@@disrael2101 registered ports are usually reserved for applications that are running on the computer. The range can be changed use a command on the computer. You can have more registered ports but less dynamic ports. However, well known ports don’t change.

If you are unable to understand any topics related to networking from any other sources, just don't worry. This channel is for you. The explanation on these videos will help to memorise the topics in a way that it will last longer than any other sources. The videos on this channel even helped me through 2 of my interviews during my first 2 jobs in the networking and system admin field. I couldn't thank you more.

[@guillaumemasure2657]

Dear expert, your videos are perfect; clear, simple and efficient. Thanks a lot for sharing your knowledge !

[@VijuKurian]

[@cyb3rkahn]

You have expalined my 4 years CS Degree in few hours in easy way. Thanks for these awesome contents.

[@NaguTexan]

In future, there will be no colleges or universities. Everyone graduates out of KZbin University. Content is more valuable here !!

[@alexg963]

Oh no question. The internet has truly democratized education. Colleges are on their way out. And in many ways, it’s probably for the best.

[@vomitkermit3446]

Unlikely, learning this is the equivalent of learning the alphabet. TCP gets very complex very fast, requiring some sort of schooling to set up and manage networks. And this video is for ipv4 which is a standard that is currently being phased out.

[@jordanfuller3046]

Not true. School is needed.

[@serialdreamers9261]

Thank you for this beautiful video, and the Kindle suggestion. I am now enjoying 2 months free and have a proper textbook course to guide me. I have been experiencing some really tough times since 2016. It has severely affected my ability to be ambitious, set goals and work toward accomplishing them. I am interested in following a cybersecurity course and feel it would do me a world of good to understand networking before going into security wholly. Your videos have and continue to be a great source of inspiration and support for me. Not too long, not too cramped, simple words with practical illustrations. I will come back to this chat within the next 12months to show my appreciation and update you as to how my journey has gone. Thanks again🙏🏾

You guys are the best. Please post more often and explain networking with cabling installers in mind. We need to troubleshoot real time issues and don't always have IT support.

[@ubi-wan-kenobi]

I searched for the best possible explanation for Port and you delivered so effortlessly and well. Thank you very much. This deserves a follow

[@ahmad-murery]

Very well explained, I always wondered what are those random port numbers came from on the local address, but after watching this video I realized that it's necessary to deliver the server response to the same application that requested it, Although I didn't get enough of this type of videos, but do you have any plan to make one explaining how to properly setup a local network with some tips and tricks for diagnosing network problems? Thanks & Regards

[@batista98854]

Ya same. Even I was confused and this video gave me clarity. Will have to watch another time will give more clarity

[@rasara]

Torrent apps by default use 6881-6889 ports. Knowing this some internet providers will block this range of ports so that you can't access torrents. (But you can bypass it by changing the the port number in the app.) This is a good explanation how ports or their blocking works. Your firewall probably blocks all ports except the commonly used ones which are featured in the video.

[@juancar331]
