Thanks very much for your videos professor messor. I have been watching your videos for years and they always are great. You break down something Complex and make it easy for us busy engineers to understand. You helped to pass my NET+ and my SEC+. Without you I wouldn't have got them. Thanks and a very Merry Christmas. Much appreciated 👍
Wait a minute...isn't the connection the Professor is pointing to @2:15 just another fiber connection with a Straight Tip connector instead of a Local Connector? If it's copper, why is the cable itself so thin?
In a way, yes, I am not educated enough to explain how exactly the systems handle it except saying as far as I know it mostly relies on caching, and a lot of communication back and forth about what and how much to send and some prediction based on the system clocks. This is one of the major problems original super computers had, as the input/output and the physical lanes throughout the computers were slowing all of the computing parts down.
To go further with this in modern times the average hdmi can do 60 frames per second. There are special ones that can do 120. Lets say you upgrade your monitor but you just plug in the hdmi that is already there. There is a high chance that monitor will only be able to do 60 fps while that cable is plugged in and your pc will see and know that as a fact. Data throughput is important.
I have a doubt about QSFP & QSFP+ : the way I understand it these transceivers enable us to send 4 different flows of data through a single strand of fiber using different wavelengths, did I understand correctly ? If I did, that means a BiDi QSFP enables a single strand of fiber to do the work of 8 ?
transceivers can both send out data and read/respond to incoming data. trans - to send ; ceiver (from receiver) to take on, to inspect and read/ the media converter has to change the output of a signal so that another type of wire can read that data to make it useful. fibre and copper connections cannot communicate with each other because they are 2 different mediums of moving data.
So useful for people like me who have no actual I.T. experience. It's nice to put pictures to the words we study!

Thank you for these videos. Thanks to you, I've past A+ and Security+, now on to Network+!
You passed only using his videos? I'm studying his videos just to learn but if I can pass the exam with this info maybe I should try to get certified
Thank you so much. very useful and easy to understand.

Thank you!
Do Bidi tranceivers enable full duplex over the single strand, or is it simply a way to enable half duplex?
BiDi is full-duplex over a single strand.
at 1.18 its mikrotik router a good one but wiered it doesnt have sfp in the other side?
is there a backup of data when a faster (fiber) comes to a transceiver and converts to slower ethernet?

So if you convert copper to fiber does it cause any type of packet/data loss?
there is some loss because copper is more susceptible to RF waves, of course if you are using UTP.

I am a bit confused on the difference between a transceiver and media converter
transceivers can both send out data and read/respond to incoming data.
trans - to send ; ceiver (from receiver) to take on, to inspect and read/
the media converter has to change the output of a signal so that another type of wire can read that data to make it useful.
fibre and copper connections cannot communicate with each other because they are 2 different mediums of moving data.
