Just in case anyone else can find it useful I remember the difference between TCP/UDP by thinking of the T/U as Tethered/Untethered instead of transmission/user. Helps me remember TCP is connection oriented and UDP is connectionless

[EnightEcho]

Here's how I remember the idea of IP addresses and port numbers. Every apartment building has an address, every computer has an IP address. Every apartment in that building has a number, every application has a port number. Hope it helps 👍

I don't think I've ever gone from "yeah I understand everything you're saying" to "oh my gosh I have no clue" so quickly.

man ive never felt like i was missing out on a job so confidently until i started watching this play list, 90% of the info is stuff i knew. thank you for helping me realize

[samanthageiger]

I genuinely don't believe I would've passed my certification if I didn't find Professor Messer. I am forever grateful and all of this FINALLY makes sense to me. Thank you thank you thank you for breaking it down and making it more easy to digest. :)

This is the first time ive encountered someone who explained IP similiar to how I understand it.... When it comes to network addresses and end hosts, I see the network address as a neighborhood, and the individual IP addresses are the individual houses in the neighborhood

Professor Messer - the undisputed G.O.A.T.

Great piece out there for some of us from Africa. This job you are doing is Godly. keep it up. God bless you, Prof.

[lyncker]

This is really well done, I'm happy I found professor messer on my way to the comptia a+ The truck example for IP really helped visualized the inside happenings of IP. Thanks professor

[southernfrechman]

Thanks for this clear and sharp explanation .... the truck and house delivery simile was brilliant 🙏🏼🙏🏼

[papa.sloth.]

I’ve always had issue with figuring out ip addresses, this made sooo much sense to me. I love finding people who can make things so clear to me

[VetinCloud]

I dont consider myself new at this. Yet i keep coming back to review material. So thank you for what you do Sir.

[lordsavior]

this is so clear. always thou networking was my least known subject but you make it so simple to understand thank you professor

[gabl]

Wow, I've learned so much in 18 minutes thats crazy!!! This high quality content!!!

[Lupr]

This is definitely one of the more difficult videos to grasp, even as someone who has hosted home servers before. I'm sure now that I've gone through it once in detail I can watch a few more times and have a very solid understanding.

[Vanity]

I’ve probably learned this portion 3 times and this is my first time throughly understanding 😂

[JesusGil-dvtm]

Excellent. This video on ports on a network helped broaden my understanding of them.

[simpleh]

Thank You for simple explanation of TCP/UDP protocol!

[deletethisnananabz]

So this has to be updated every 3 years? If I smash this exam in a couple weeks it’s going to be good for a year then I have to do it again. Sigh. I’ll do what I have to do. Thank you for making these videos for free. You are a hero Professor Messer.
