Hey Jeremy, start the video at 28:02, within a few seconds you state, "Because the network portion is very long..." It is regarding Class A, so you meant to say, "Because the network portion is very short", "Because the network portion isn't very long", or "Because the host portion is very long."
lets appreciate this guy for making the entire awesome playlist free for us. May God give u more health and peace in your life. Thankyou from our core of hearts♥
I happen to read this comment when spotted a deduction error at 16:00. "Math teacher" sounds quite ironical in this context. LOL Just joking ofc - happens to everyone. Fantastic explanations and teaching skills. Thanks a lot, Jeremy!
@@ivanjuresa4208 Literally I have bene scratching my head at this for the past hour. Anyone that says this guy should be a math teacher hasn't been checking there work.... fuck me what a waste of time that was.
These comments are not to ask any question, these comments are just to say that "YOU AND YOUR VIDEOS ARE WONDERFUL" It is an easy and detailed (even only necessary details) way of delivering the knowledge. I have been a teacher myself and I understand that having knowledge is something else and delivering knowledge is something else. Thanks.
Sometimes us IT guys are great at learning and terrible at explaining something in an understandable way (typically because of far too much of an assumption of previous knowledge to whom we are explaining); you are quite awesome at explaining!
I did self study with many different IT courses, including Linkedin, Google, and other youtube channels, but found Jeremy's course is the best because it's a well balanced one, has a lot of theory, and also Lab practice with hand on experience. Very good, thank you Jeremy.
This is Soo amazing Mr Jeremy Soo loud and very clear. Truly appreciate it. For 4 months i have been struggling to understand ipv4 addresses and all the conversion of the binary to decimal and decimal to binary. Now i gat it all. Thanks u once again...💪🏿🥰
Hi Jeremy. You explain these concepts in very easy to understand terms. I took a college course on this topic and the experience I'm getting from your course is so much better. Nice work!
Awesome job, Jeremy ! I 'm watching your videos from the beginning (Day 1) , and I'm very satisfied until now. One suggestion: since many of the viewers have previous knowledge on some of the subjects, it would be great to split each lesson into chapters and put markers in the description. Thus they could easily skip or review some parts.
Hello Jeremy, Thank you for doing such an awesome job. Your videos did help me lot to understand the material. BTW on your video there is a minor mistake on 16:57 where the decimal to binary conversion should be 11011101 instead of 11011100.
Jermey, you are the best one that explains CCNA in such clear and easy way! Really appreciate your effort and thank you so much for these great videos. BTW, I'm telling all of my friends about your channel because you deserve it. Thanks again.
A little trick I'm using to calculate the decimal from the binary is that if the majority of bits are 0 then I add up the 1s columns, but if the majority are 1s then I deduct the 0 columns from 255 or whatever the maximum possible is (if there are 0s on the left side so I deduct from whatever smaller number would be from all 1s up to the last 1) if that makes sense.
I can not thank you enough Jeremy! It's a been a few rough months for me on the IP addressing topic but today after watching this video I think I can finally say rhat I got it! Besides, I now know what the slashing notation means! WOW!!!! I'm really grateful. 😭🙏
Hey Jeremy, I have just come off a 7-day CCNA bootcamp with Infosec I planned on using the course to grow my area of expertise at work and was initially very excited to attent. However, the course did not go as planned and I felt like I was drowning the majority of the time as the majority of it was hands-on with little to no explanation of theory. I've worked through the first 7 days of your course over the weekend. Feels like you hit the balance of theory and lab the head, you provide reinforcement along the way, and do it all engagingly and concisely. Looking forward to the rest of the content and thank you dearly for your time and effort on this. You have a real gift for teaching, thank you for sharing it with all of us!
You are a God send mate. I'm taking CNNA 200-301 without any previous IT experience and it is quite hard I guess at the start but you are making it so much easier, I'm going through your videos even in class as I'm taking CNNA in a language i'm not very proficient. I'm just worried there isn't enough of videos to go through. Im also using the cards and hopefully soon will be able to tip you for all the help .

Thanx jeremy...i am from india and i am finance professional .. I always found IT very difficult...but it seems i am about to add one more skill to my portfolio ..thanx to you sir👍
Am preparing for my LAAMAN exams and these videos are really excellent. You explain so well and make it easy to understand. I feel I should do my cDNA certification soon. Thanks for your generosity.
I feel obligated to comment on his videos as I watch them. So much passion in each topic. Really helps keep me motivated. I understood the binary perfectly. I am really struggling to grasp how hexadecimal works though. The math isn't clicking for me.
I don't have any experience with Computer Network but i want to take CCNA because i want to continue my IT career. Thank you Sir for providing free courses. I will take my exam on August.
Watching this video as a review after taking the TestOut course for Routing and Switching Pro, I was struggling to memorize the 5 different classes of IP addresses. However, when you put all of the classes in a table using binary to categorize them, it made so much sense! Binary has become second nature to me after tons of practice, so remembering which IP address range is in which class has gotten much easier for me after you used that representation. Thank you for all you do!
I love the detail with which you explain all the concepts. Your tutorial videos ae the best I've experienced. Thank you for taking the time to create this series.
this is the best explanation I’ve ever seen for binary. I remember someone trying to teach this to me before, and I can’t remember the tricks I learned with that method. with this one, I don’t see how I could forget
We can also convert decimal to binary by dividing it by 2 each time and noting the reminder. Like 127 to binary 127 % 2 = 1 63 % 2 = 1 31 % 2 = 1 15 % 2 = 1 7 % 2 = 1 3 % 2 = 1 And last note both reminder and quotient 1 % 2 = 1 1 / 2 = 0 Reading backwards you got answer 01111111.
Thank you so much Jeremy for put all your effort to make understand very easily and concern about us how we understanding every lesson, the quiz your giving every lesson that is lot of helpful for us. What the respect we have on you that's going on another level everyday. God bless you.
Not sure if this is relevant, but I memorized 2,4,8,16,32..8192,etc, pattern before even starting to study CCNA, using games. Something like "X2 Blocks" game on Play Store. There are many similar ones, but I have the numbers already burnt-in from my childhood because of those. Really makes the 2^n pattern become a piece of cake for me to count. Hope this helps someone. BIG THANKS TO JEREMY FOR SIMPLIFYING EVERYTHING UP TILL NOW!!
I believe at 5:38, you state that "If *R1* sends out a frame with the broadcast mac address of all F's" when it's actually PC1 sending out the broadcast frame. Just a little slip of the tongue I thought I'd point out, unless I'm mistaken.
This subject matter is way out of my comfort zone. Yet the explanation of these concepts is so clear and concise, even an idiot like me understood it. Seriously great job. I've now completely abandoned TestOut in favour of this course.
@@speedysui I do this in the morning (weekdays), I take notes while watching the video. After that, I study the notes, then rewatch the video. 🤣 During the night and weekends, I study the past lessons. 🤣 Don't focus on the speed. Take all the time you need. 😄

Jeremy, Many thanks for this amazing course and for your great effort to make it so simple to understand! God bless youy life for sharing us your knowladge about Networks CCNA
something that made me get a AH HA! moment is realizing that the lower the number on the OSI model the closer you are to the source. So physical is the source and the farther you are is how the transmission taking place and what you are doing with said transmission. So Application layer is an app sending out a signal all the way down to the physical layer which is the end device.
not a big deal and still learned the lesson but in the 221 example converting to binary 93-64=29 not 28 thus changing the answer to 11011101.11011100 is 220 Took me a second to catch it.
Damn, I was in the garden listening while watering and doing the binary in my head and heard that you didn't have the "1" bit "on" for 221, and thought, 'that' not right'. I came to the comments section, all proud of myself, to point out that for any odd decimal value, the 1 bit must be on, only to find you already pinned it to the first post 😔 (bubble burst). 😄 Thanks for all the great content, though. I got your CCNA course, and am just now checking out the flash cards. Hoping to take CCNA exam soon. 👍🤞 (Also, tip: to solve for 221, subtract 221 from 255 and you get 34, so just disable the 32 bit and the 2 bit - that's how I sometimes approach it) (another example, the decimal 207: just subtract 207 from 255, you get 48, so just disable the 32 and the 16 bit - this method allows you to calculate these in your head in under 2 seconds, usually, without looking at paper or anything. I find it a helpful, quick way to calc binary octets.) Hex, on the other hand, I'm hoping you have some good shorthand for, cuz it always trips me up.
Hello Jeremy, I want to say thank you for this amazing training, since I discovered your channel I have learned a lot from you and I have gained confidence. Please kindly provide for me a playlist for CCNA 3 so I can be able to focus on it. Once again thanks and my God bless you for sharing your knowledge with us
Thanks for your kind words! All of my CCNA videos are in this playlist: ua-cam.com/play/PLxbwE86jKRgMpuZuLBivzlM8s2Dk5lXBQ.html I'm not sure what CCNA 3 is, is that a specific course?
Thank you Jeremy, I have seen and taken many course but this is most comprehensive and easy to understand course, you are the best instruction. I just want to know how do we determine which is network portion and which is host portion without knowing /8 or /number? Thank you.
If you don't know the prefix length (written as /8 for example, or in dotted decimal like 255.0.0.0), then you can't know what is the network portion and what is the host portion.
The easiest way to convert from decimal to binary is to do series of divisions by 2 without reminder : 221 / 2 [1] (bit 8) 110 / 2 [0] (bit 7) 55 / 2 [1] (bit 6) 27 / 2 [1] (bit 5) 13 / 2 [1] (bit 4) 6 [0] (bit 3) 3 / 2 [1] (bit 2) 1/ 2 [1] (bit 1) We divide the number by two and write 1 when the result is odd and 0 when it is even. The last division gives the first bit.
16:46 = I believe this may be wrong 128 + 64 + 0 + 16 + 8 + 4 + 0 + 1 = 221 But I do like that style of working it out' Sorry, I wrote this before I saw your comment above. Great lectures though
Hey Jeremy, I am planning to give CCNA exam next month and i am watching your videos, these videos are easy to understand and really helpful. thank u so much. I just wanted to ask, Just watching these videos and understanding the concept, is it enough to pass the exam
I like the quiz on converting binary to decimal and vice versa. I am already familiar with the sums of 128+64+.. for when I'm computing the subnet masks in vlsm, but having different binary patterns worked my mental math skills haha. I only made 1 mistake on #2 because I forgot to add 15 to 112 to get 127 even though 15 was the first thing I computed 😅
ERRATA: From 16:00, decimal 221 is actually equal to binary 11011101. Spot the math error!
I was going to write to let you know, thanks anyway, your presentations are very clear and educational.
I spotted it as all numbers were even except 93 and subtracting an even number from an odd number will always leave you with an odd number.
It happends, that not so serious ;)
So I had that written down and then when you gave the answer I was like, ok...it's been some years so I was wrong.
Hey Jeremy, start the video at 28:02, within a few seconds you state, "Because the network portion is very long..." It is regarding Class A, so you meant to say, "Because the network portion is very short", "Because the network portion isn't very long", or "Because the host portion is very long."

I injured my knee doing blue collar labor, boss told me to keep working on it. I quit and started watching your video series lol
the best elaborate and you have all the time to explain very well.
The easiest way to convert from decimal to binary is to do series of divisions by 2 without reminder :
221 / 2 [1] (bit 8)
110 / 2 [0] (bit 7)
55 / 2 [1] (bit 6)
27 / 2 [1] (bit 5)
13 / 2 [1] (bit 4)
6 [0] (bit 3)
3 / 2 [1] (bit 2)
1/ 2 [1] (bit 1)
We divide the number by two and write 1 when the result is odd and 0 when it is even. The last division gives the first bit.
Hats off Sir Understand Each and every topic in this Lecture 🙏👏👏❤️❤️❤️
Nice, I'm glad to hear that :)
16:46 = I believe this may be wrong
128 + 64 + 0 + 16 + 8 + 4 + 0 + 1 = 221
But I do like that style of working it out'
Sorry, I wrote this before I saw your comment above.
Great lectures though
Im grasping the information i just need to work with it some more 😊
EDIT: I felt stupid at the beginning but passed the quiz with a perfect score! 😁😁
Thank you for being direct and to the point.
Please upload more videos in CCNA and computer networking sir.
The next video will come soon! Thank you :)
Better than CSN! Thank you soooo much. Now I finally get it.
Hey Jeremy, I am planning to give CCNA exam next month and i am watching your videos, these videos are easy to understand and really helpful. thank u so much. I just wanted to ask, Just watching these videos and understanding the concept, is it enough to pass the exam
best explanation i ever seen
Thank you :)
I like the quiz on converting binary to decimal and vice versa. I am already familiar with the sums of 128+64+.. for when I'm computing the subnet masks in vlsm, but having different binary patterns worked my mental math skills haha. I only made 1 mistake on #2 because I forgot to add 15 to 112 to get 127 even though 15 was the first thing I computed 😅
Glad you liked it ;)
wow...so thankful, you are great teacher.
Thank you!
Great and thorough explanation
Thanks, Mark :)
Been loving this course, but I have to play in it either 1.5 or 1.75
