Common Network Ports - CompTIA A+ 220-1101 - 2.1

- - - - -
We use port numbers to differentiate between applications as they traverse the network. In this video, you’ll learn which port numbers are used by some of the most popular protocols.

I've completed an 800hr Cybersecurity Bootcamp, completed Googles Cybersecurity Certificate Program and have been Studying material from a 40+ hr Udemy Course to take my Security+ exam and this is the first teacher that has taken the time to legitimately explained in detail the purpose of ports and has given the learner an in depth rundown on what each common port is used for.

No knock on the other teachers, but after watching this, I really feel like veterans in this industry sometimes fail to remember or consider one major thing about many of their have no idea what you're talking about! Lol thank you for helping us UNDERSTAND rather than taking the easy way out and just throwing information at your learners. You're a solid guy 😎👌

[OurRooks]

Man I hope I can pass the A+ stuff off of your sources, I can’t handle the job I’m doing much longer

[pneumantic]

If you are watching this and are worried about passing, just take a break and come back (like a day). A good way to deal with this is to learn each chapter separately as parts, it will give you some enthusiasm to do this. Specifically, being able to recognize progress by using things like flash cards. You would be surprised to see just how much you retain when you use recall rather than blatent memorization.

Got my A+! I started a homelab and immediately found myself modifying SMB services and using SSH to manage headless devices! All your lessons helped me understand what I'm working with more clearly, thanks.

[lb]

I like that you put the ports in order.

[sthsational]

Just took three pages of notes on this one video.

[sokymdi]

Just changed my passion from programming to networking, i'm learning the basics from these videos. This 14 years old boy learnt a lot from you, thanks Professer Messer❤

[ZombieWolfe]

this is actually really good, I'm using this to get a refresher after graduating in 2018 and this is a lot of the stuff i went over in my college classes

[catsforhire]

This is the video I have watched the most haha, had to go old-school and make flash cards to memorize these.

[thesentinel]

Are we not going to talk about how good that cheese looked

[senjurooo]

Wow, this is a lot of info to take but it's fun and I'm learning new things. Thanks Professor!

[bretsinclairofficialuk]

I just failed today on compt tia a+ 220 1101 at a score of 635 and i needed to get 675 i was close, going to use these videos to re study

[JBpointfour]

Professor Messer,
First I want to thank you for putting this all together. I can't imagine how time you spent on all this.
I am a Help Desk Technician and was wondering what is meant by ""usually multiple DNS servers are in production." I am thinking that it means that since the services that DNS servers provide are so integral, that it is very common for a network to have multiple DNS servers in your network for the sake of redundancy and if one goes down. Is this a correct translation? wink!

[TyrianHaze]

Greatest thing I learned from this video: to say dub instead of double-u to save a few seconds. As a computer engineer, I appreciate this new found efficiency.

[JKingSniper]

Coming here after Security+, nice to recognize all these

[miomeo]

Seems like some network ports have been reduced from the previous exam version?

[stoiccrane]

When configuring SNMP for a device is there ever a good reason to use versions 1 or 2 over 3 since the third is encrypted? When it comes to file transfer what is the difference beween FTP and SMB? Are they interchangeable?

I really want to watch and participate in an active live 1101 study group by Professor Messer and ask these questions but my work schedule is getting in the way.

[MFmyk]

thanks for your videos! re-watching clips before test. Question- Why is SMB protocol used to transfer files instead of FTP? (FTP is literally for file transfers but SMB is the one that is used to communicate and send files between devices. I don't understand why or when it would be used then.)

[giokaios]

Guys I went to the comptia website to book the 1001 test but among the languages it is not showing english? do you know why?

[brandonclarke]

Someone answer this for me, please. In the section on SNMP, he says it uses udp. I thought that protocol didn't have encryption, so how does SNMP v3 have encryption?
