    Even if you have been in the field for a long time it can be valuable to come back to these videos. In school a lot of concepts are abstract and lack context. Once you see them out in the field you understand them better. Then you come back to the education with the knowledge from working in the field and a lot of light bulbs start to come on.

      @JJFlores197 9 месяцев назад

      Yep. I fully agree. I took a few Cisco courses years ago at a community college. The instructor was pretty good. She gave a lot of examples, but they weren't really tangible. The hardest part for me to grasp (other than subnetting) was the physical infrastructure of how routers and switches and patch panels, etc are all laid out. It wasn't until my 2nd IT job at a school district that I started to get more hands-on work with the network infrastructure that I started understanding a lot things.

    When we break down network communication (or any computational communication for that matter) like this, its mind boggling how quick and seamless it all works. Heck, how it even works at all.
    It is beautiful to be completely honest. Maybe being able to appreciate it is what makes all of us IT folks techies in the first place.

    The difference between TCP and UDP in the best way I have personally ever seen/heard:
    TCP: Cradling your baby and gently putting them into their crib, ensuring that they are tucked in and comfy.
    UDP: One word... YEET!
    I've yet to forget the difference after being shown that lol

    I can't belive how much I've learned purely watching this series. I'm currently following an IT course in college (2023, putting this here for future references) and I have learned more about networking in this course in few days time, compared to what my teacher is explaining during class for the last few months.
    The way you teach this, is literally how teaching this should be. It's fun, it's packed with lots of difficult info broken down into info that is easy to understand and remember, the simple and very clear sketches are such a big help and the 'interaction' with the class / community is how many more IT teachers should be interacting with their students

      @ugetridofit 4 года назад

      What i would love to see someone address is how things on the network keep from talking over another. For instance, say on my network I have 3 people streaming 4k videos, while I am doing google searches, and then I also have 10 other networked devices like 4 IP cameras streaming video data to my DVR, and other network devices. That is allot of data flying around through the switch. It seems obvious that the switch handles data to each device in a controlled manner so that one does not talk over another. But that would think that this would mean that each port on the switch is time slicing the data to the WAN port.

    First of all, thanks Chuck for producing these videos with the excellent content. They are both fun and deeply instructive without any "fluff". I was following your tutorial on my own PC with Wireshark, and I noticed that instead of UDP, RUclips is using the QUIC protocol now (RFC 9000). I was not familiar with it and so I looked it up--apparently, it is a protocol that is built over UDP that includes security but is faster than TCP.

    To this day I associate a TCP "Ack" with
    Bill the Cat from the 80's cartoon Bloom County.
    I was working on a clinical lab network.
    We used a service in Nebraska to talk to a hospital computer down the hall in silicon valley.

    Hate sound like a broken record, but I haven't been this excited about networking and I love the Packet Tracer.

    Words cannot express my thanks and gratitude to you for such an entertaining and excellent presentation on the CCNA project. Have learnt so much - still not up to passing the exam but fingers crossed one day. If possible could you at some time do something on the config and connection on the wireless AP. Congratulations on a very well done job. Many Thanks.
