Learning net+ in 4k has never looked so good!

[@JamesBrodski]

Thank you for making this video. This is the one that requires the most studying for me!

[@tamiekamaxwell2154]

Great refresher as usual! Looking forward to the Live session. Thanks for all that you do.

[@safwansyed4521]

I love how detail these videos are.

[@rajsharma7293]

Thank you professor for all you do.

[@rsreatheaers2489]

Perfect timing!

[@analeila]

How many of you screamed NOOOO when you saw the two folders with the papers? Good reference there, professor Messer. Thank you for the awesome videos.

[@JuiceManTech]

Thanks for the video

[@kevinbrown259]

Great Teaching

[@aruizsilva]

thank you!

[@mattmadarasz3794]

The objectives show some of the ports use SSL, whereas the video showed TLS for some of the ports. Was this a mistake and does it matter?
Thanks in advance

[@professormesser]

Although almost everything is TLS these days, we still often colloquially refer to it as SSL. If you see anyone talking about SSL, they're really referring to TLS.

[@epiclight858]

8:30 in the video explains this with HTTPS

[@IsaacSMILE]

Lord praise the Messer!

Why is there Swiss cheese pictured for SMB?

[@professormesser]

It’s a block of cheese. They can’t all be winners, people.

[@fredericapanon207]

@@professormesser I was surprised to see that you said SIP for VoIP used TCP on port 5060 and 5061. Is that only for session initiation, then the actual call data switches to UDP?
When doing a search for SIP protocol, UDP gets mentioned. TCP only gets mentioned regarding how it is not suitable for VoIP.

Taking net+ early October

[@wing_gundamzero_5433]

Good luck! You got this!

[@zstick]

How'd it go? I'm always curious. Anything you wish you'd done differently?

[@harrisneiditch6810]

Thank you so much for these videos, Professor! How do you keep in mind the difference between SMB vs. FTP/SFTP?

[@bzorb7279]

ya momma

[@DanBlabbers]

SMB is client to server where multiple endpoints can alter a file on the server. FTP copies file on client and sends to server.

[@Bill-fx1kf]

SMB is primarily used for scanners so S, FTP is used for files so F

[@JT4NN3R]

@@Bill-fx1kf Good tip! Glad i took the time to read comments, this is gonna come in handy.

[@somnus1057]

What's the point of UDP? I always felt it is inferior and can't see any pros to using it.

[@cmon200]

from my understanding udp is faster and is used for streaming service where it wouldn't matter if the receiver didn't get every piece of data. like loosing a frame on a 30fps show wouldn't matter that much

[@iSgapetti]

Aside from streaming (video or music, etc.), it's also used for voice and video calls. It's used for real-time sync in online multiplayer games as well.
