🎇✨🎆💥Hello, thanks for your work. Your Video Design is neat, and topics very interesting and well covered. I would like to address some details regarding this video :
1) According to every reference I came across, "RJ-45" is a wrong name for what is actually 8P8C connectors. Of course I know most people use the wrong name, but I think you could consider citing at least once the appropriate name.
2) You present STP Shielded Twisted Pairs as cables for RJ-48 connector, which are used in T1 lines. How come that everyone talks about STP 8P8C (A.K.A. "RJ-45") cables for Ethernet lines, not just T1, including yourself in your own video ua-cam.com/video/_NX99ad2FUA/v-deo.html "Ethernet Cables, UTP vs STP, Straight vs Crossover, CAT 5,5e,6,7,8 Network Cables" ? You seem to contradict yourself!
May we know your take on those two points? Keep Up The Good Work! 🖖😀👍
@@philpeko1796 You are wrong about RJ-45. 8P8C is a term used to describe the specific details of the cable standard. The 8P8C stands for 8 Position 8 Contact. Which means 8 wires connecting to 8 conductors. That is why RJ-11 can be also called 4P4C. Although, "ethernet" is a general industry term used to describe network copper cables. RJ-11 is also ethernet and so is RJ-45. Hope this helped :DD
@@jammel3653 This is right, 8P8C is not specific to Ethernet TIA/EIA-568 (T568A and T568B). But what is also right is that "RJ-45" originally refers to a specific wiring configuration of an 8P8C connector, for which a telephone-system-standard RJ45 plug has a key which excludes insertion in an un-keyed 8P8C socket that we all use in Ethernet TIA/EIA-568 cables. The point is that "RJ-45" was already used for specific telephone cabling with keyed-plugs, and it should not have been used for Ethernet TIA/EIA-568 cables. Do we agree?

I’m 53 yrs old and I decided during this pandemic to learn IT and your videos have been very didactic and so clear that I wouldn’t find in any other IT courses.
At 52 during the pandemic, I did the same thing.
true
I lost a pandemic opportunity to learn skills 😢 now struggling for interviews
I am not at your age just a boy in his 20 trying to earn knowledge 😊
The legend is back.
only has been 4 months, working on this video and maybe even taking a little break
come soon ， cool！
the myth , the man , the legend ...
Yes
And in 16:9 HD!
I start watching videos from this channel like Netflix series, one video after the other. Very good!
Glad you like them!
Me too!
Same here

Thank you, author, for you work and simply presentation of theory materials.
Big respect from Republic of Belarus.
These animations are awesome.
140 dislikes probably have a general problem with connecting.
Wonderful lesson! I didn't know much about RJ-48 or fiber cables. This helps a great deal.
Nice video you should start doing best settings videos too, you are one of the few on youtube that actually knows their stuff.
Beautifully explained and so easy to follow. Gratitude and well done!
Great explanation and clear animations. Solid sound quality and texts without errors or jokes.

Welcome back we have been waiting you for a long time.
Finally!!! I found a video that explains the very basic of basics of basic of cables and wires, no longer will people make fun of me because I don't know what a Type C is or HDMI...
One of my online teacher. Thank you for video.
So good to have you back!
Super helpful! Love it. Thank you.
Very useful info, so clear and to the point. 👌
After a long time i am happy to watch a new vedio.I got a lot of help from your channel and the vedio(s) too!! Keep making such useful vedio. Be safe and healthy!!
Your videos are amazing man!
KEEP IT UP!!
The power point legend!
Thought you were no longer active. This is great!!
Thanks for coming back 👍
found a bug (push-pull connection vs pull-pull connection: one thing said another written) Great videos! Can't stop looking through all of them. Very Educational.
Good Lord you have a knack for teaching. Don't stop. Liked and subbed.
Thank you for the very informative video tuturial about cable internet connectors and adopters.
Sir, beautifully explained. Can't believe this is free.
Most accurate explanation ever
oh wow youre here
Very good overall, expect for the last phrase. APC is used in order to have a better return loss, the signal loss or what is formally called insertion loss in usually slightly worse in APC than UPC.
@@vladulescuadrian6080 what does UPC and APC stand for i coudlnot find on the video nether google
@@leto1449 UPC = Ultra Physical Contact / APC = Angled physical contact
ofc its you again...
It takes a shitload of time to make these kind of videos ...thanks for the efforts ❤
Dude love your vids, keep it up man!
How simply you explain. Lots of love for u mate
This helped me a lot. Loved ur explanation.❤️❤️❤️❤️❤️ Thanks.
Been in IT for over twenty years and know and have worked with most of this. Still watched the whole video. Like asmr for nerds.
I really like your videos, keep up the good work! In video connector and USB videos you really helped me. I finally know what sort of cables are on my 2012 laptop! =)
Sir, I love you! you are the best teacher in the world!
Please make as many videos as possible, because I have choosen your videos in 1000 , the best training
Thank you sir. It's very useful. You explained this clearly understable.
Your teaching is very good sir and thank you for your clear and clean teaching .
Finally Got The Video I Was Looking For
A useful reminder. Will play it a few more times before my A+ exam
Your videos are very helpful.. Thanks for this type of videos
I really appreciate your works. Love from India ❤❤❤
Hello Sir, I'm in love with your teaching skills, the animation + your way of teaching is just awesome, super easy to grab.
Anyways, This is the very first time I'm making a request to someone on UA-cam, *CAN YOU PLEASE UPLOAD A VIDEO on the topic of "OSI MODEL"*, Please?
If anyhow you can read my comment and can do it, I'd really appreciate your help..
Thanks and keep doing the great work..😍😊😊
Seen you after long time mate , thanks for your efforts
keep it up power cert.......i really appreciate your work..... & I would like that next topic should be OSI model.....🙏
Seriously missed Ur videos a lot sir🔥🔥🔥🔥
Good to see your video after long time!!!!
A new vid! Yeah!👍😃
Lots of good info in this vid.
5:01 But the fibre optics cable part, literally caught my attention more. It actually uses pulses of light to send data? That is some serious Metroid Prime Chozo + Luminoth alien technology thing going on there.😲
Thanks for this new vid.👍
good show my man!
I've been waiting for a video like this
The return of the king!!!
Absolutely very helpful!!
what a amazing explanation, Great video 👍👍👍
We really appreciated you sir . Great video's easy to understand. Could you please do some more videos on A+ 1001
please try to upload more videos about networking because you guy give easy explanation that could easily understand
Great video again, thanks!
Quick comment on 5:36, you say "push-pull connector" but write "pull-pull connector".
Many thanks and see you next time.
you are welcome
As usual awesome content!😎
best networking channel in the world
Thank you so much for your videos 🙌
Really become a computer master..!!thanks a lot :)
I am glad the days of Cross over and straight through RJ-45 cables are things of the distant past.
Thank you ! It really helped me a lot.
Wow that is very knowledgeable!!👍🏻👍🏻
Very smooth and pleasent video
The man has returned....!!!❤️❤️❤️
Hi, Fibre (Fiber) connectors are all highly polished and thus will reflect light, reflectance. PC means physical contact and UPC is Ultra polished physical contact. The reason we use the 8 degree angled physical contact connectors is for high power LASER networks. A standard PC or UPC will reflect too much light back in to the LASER that can upset data transmission symbols and cook the LASER which is already running very hot. But the APC allows the majority of the light through and any reflected light is directed in to the cladding and then the buffer but does not make it back to the LASER. Hope that helps.
Do a video about video cables if you haven’t already. Great vid!
Also, a video about obsolete cable types such as PS/2, parallel, 9 pin, and those random ones you hardly see anymore nowadays due to newer formats.
LOl I still use Ps/2 and sometimes parallel.
Great content!!!!!!! Please keep it coming
Headup for misinformation: RJ-45 connectors comes in 2 types: shielded AND unshielded. The shielded cables in reality do NOT come with a type that has a shield covering 4 unshielded pairs, think about the crosstalk here. Instead all 4 pairs are individually shielded, preventing the signals in each pair to interference each other. Also this kind of shielded cabling is usually only way to build a working Cat6a or Cat8 network (We do not talk about Cat7).
Ur content and it's explanation is awesome
No body did video on this. Very informative 👍❤️
Excellent work, keep the good work and don't worry
Allah will reward you for your efforts
You are seriously GOATed my guy.
Absolute GOAT of the IT world!!
your contents are priceless...
Smooth and simple .
