Network Ports Explained

What is a port? What are port numbers? A port is a logical connection that is used by programs
and services to exchange information. It specifically determines which program or service on a computer or server that is going to be used..whether that is pulling up a web page, using an FTP service, accessing email and so on.

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!

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.

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!

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!

[richardhyman]

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!

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.

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!

Your video is amazing. As a beginner who is looking forward to move from Engineering background to IT, I would say this is the best so far. It helps expand my understanding

[NaguTexan]

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

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.

This was by far the best content I found on YouTube 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.

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.

[glewfw]

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

[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.

[rafaelavila]

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

[zbvuwqj]

This is how a beginner can develop interest towards any subject irrespective of it's complexity. Thanks a lot for the beautiful presentation.

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.

[binodayer]

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.
