This is Far better than my University Lecturer's explanation...Simple and very easy to understands...Thumbs Up for sure...and Subscribe for more for sure
Binary Void Unless your becoming a Dr. or lawyer then school is wasting your time and stealing your money. I didnt realize when I was in Temple how much money I was losing being there til i got out.
Vincent Salamatino thats like saying dropping out of school makes you vulnerable to fascist themed conservative blogs (i.e., “truth” or “news”) which alienates you from society so much that owning an AR military rifle is your only protection from the govt thats always out to get you. Lol I’m joking but life is more nuanced and complex than that...
I'd suggest dropping out and getting certifications on your own. A lot cheaper that way. Companies mainly care about the certifications, and not a degree anyway.
Crazy helpful vid! As an IT lifer, 1st PC was a Commodore 64, I haven't focused on a PC's RAM, cache and/or guts for a few years now. Flawless knowledge update and the animation locked it in perfectly! On point, no fluff, liked, subscribed and appreciated! Keep em coming!!!!!!
great f..ing explanations dudes. Been watching your vids for the last 2 hours and I've learned so much about how computers work. Now I know what to look for in my next computer purchase (in about 4-5 months, that is). Cheers and keep up the great work!
this was so helpful, im studying for my IT exam and your videos really help me out when im stuck on a part of the book that i have reread a million times. thanks so much!
Thank you. This is a well paced video with a clear explanation of the subject. There is none of the needless padding and asides of so many you tube videos. Great job!
Great content. Clear and easy to understand. I tried learning this from Professor Messer, a couple of Q&As, and even the A+ Study book. This is by far the best explanation I've heard on the topic. And in less than 5 minutes too!
Every time I see a tech channel I never saw before, I always anticipate coming in and making corrections... but man, these videos are incredible! Short, compact, and no excessive noise. Fantastic stuff, my dude(s?).
I am a visual learner and your videos have helped me grasp these topics much more easily compared to when I only study the reading material. Thank you!
I tend to learn things much faster and complete when using visual aid and you nailed it. Man I really appreciate your videos and please make more. I finally understand what L1-L2-L3 cache means & why it’s size & variables are so important when shopping for new cpu or pc. Thanks again
Finally! I've been wondering for forever what exactly the significance of cpu cache was. First vid that has given it in an easy to understand explanation. Thank you! (new sub)
Briliant explanation. You read about all this stuff but it makes much more sense with your pictures and digrams. You cna visually see what is happening and it all starts to make much more sense.
Wow, this video is amazing! I am studying for CompTIA A+ cert. This video just cleared my mind up from all the confusions I had from reading the COMPTIA study guide. Awesome, job! Thank you!!
I really love how you explain in your videos. They are so much easier to understand. especially for those who are beginners in the I.T. field. Thanks for this.
all your videos are exceptionally good. i really wan't to thank you from the bottom of my heart for the work you put in all your stuff. You are speaking in a perfect pace, your graphics are perfect and overall it's just a pure joy watching your videos while studying.
Thank you for this video. I am taking a CompTIA test next week and have been struggling with understanding the different levels of cache. This was really informative and the digital aspect was helpful. Thanks!
Dear author of this video, this video is fabulous! You have a great teaching style and a sense for explaining stuff. If you'll ever lack ideas of what to do next in your videos, you sure can ask me! Keep up the good work, it means a lot.
Yr 2020 found your videos, you are better than our professors that always asking us to report our major subject in Computer engineering. Thank you sir.
It's lines like 2:04 - 2:32 where you come full circle on a concept that make these these videos the best tools for attaining competency that I've yet to find on the internet. Describing the purpose that mothered the invention makes the knowledge thoroughly click into my head. Great Job!
Thank you so much for explaining everything in such a clear and consise manner. This will help me a lot with an upcoming exam that I have next week. Cheers man
This is such an amazing channel, I hope this comment reaches you, you make these so easy to understand!!! I'm just a gamer trying to fix a PC and this helps out IMMENSELY. Thank you so much for your hard work
Totally awesome video , I have subcribed right away , very easy to understand , especially with the beautiful slide shows and animations . Keep on the good work !!
Your channel certainly deserves more subscribers. Awesome video and animation. Please keep up the good work. Your videos are far better than what we taught in lectures
Thanks for the video , I want to add a couple of infos about L1 , L2 , L3 and Cache Line L1 cache : 32KB - 256KB ~ 1ns to 2ns (2-4 cycles) R/W - SRAM L2 cache : 256KB - 1MB ~ 3ns to 5ns (6-10 cycles) R/W - SRAM L3 cache : 3MB - 6MB ~ 12ns to 20ns (24-40 cycles) R/W - SRAM D-RAM : ~ 60ns (120 cycles) R / writing takes longer than 90ns. L3 cache feeds L2 , L2 feeds L1. L3 cache is only used when a task is rather dense or a task, process needs computationally challenging work. - in general use case CPU makes use of L1 & L2 most of the time - Cache Line : When the processor accesses a part of memory that is not already in the cache it loads a chunk of the memory around the accessed address into the cache, hoping that it will soon be used again. The chunks of memory handled by the cache are called cache lines. The size of these chunks is called the cache line size. Common cache line sizes are 32, 64 and 128 bytes. A cache can only hold a limited number of lines, determined by the cache size. For example, a 64 kilobyte cache with 64-byte lines has 1024 cache lines.
i know im like 2 years late on this video but i used it to do some revision as i am doing computer science for gcse and i am for sure going to use your videos as lessons for the next 2+ years
Bruh! You need to do more of these. You have the perfect teaching formula and the videos are right on point when it comes to time. If you do MCSA and CCNA material the planet will love you for it lol. Trust me man. I've been to college and to several certification classes including CCNP. It took you 5 minutes to explain what I've been trying to figure out for the past 5 years. **aggressively presses the subscribed button**
great explanation. thank you so much. I don't knew anything about computers totally. I knew that it has monitor, mouse, keyboard and case "with a lot strange difficult things" and even I understood everything u explained. thank you so much . . .
Thank you. So glad to have found your channel. Thank you so much for taking the time to create this content thus making this knowledge available. I am immensely grateful, I can't thank you enough. No sarcasm. In short, I came from a very povershed family, always was fascinated with IT, never had even the stability to engage such as my parents are addicts. From the side lines I have watch personal computers grow from DOS and large floppy. Even in school, I wasn't able to delve and explore as deep as my heart desired. Now as an adult, I have the time and the resources yet with all the advancements, I felt lost and was unclear of the very basics that all these awesome advancements surrounding me are founded. So again, thank you, thank you so very much, seriously, thank you. 🎉(❤+Gratitude³)
Excellent video. Great graphics for ease of explanation. You also speak very clearly and at a perfect pace unlike the other 4 TH-cam videos I just watched. Nice work.
You an amazing teacher bro. GOD BLESS YOU for all the work I put into explaining these videos and putting them out there... I'm writing my A+ soon and my N+after that and I would say ur videos make me understand better den the damn text book does.. Too much unnecessary stuff in textbooks.. U get right down to the point and that's awesome....
great job man, keep it up with the good work, i really appreciate your videos, they are well-crafted videos rich of interesting information that ppl can easly access without having a lot of technical background
Wow wow wow. So simple. Big respect for. Really your videos are so helpful, i guess even not IT people will understand it. I should offer this channel to some "teachers" how need to learn how to explain. Thanks again, I really appreciate it.
I've probably said it before, but gonna say it again: these videos are incredible
Thanks
@@PowerCertAnimatedVideos what about registers?
It's okay dude you can say it how many times you want lol
@@makara2711 😃
@@PowerCertAnimatedVideos can L1 be equated to register? I thought we had registers, L1 cache and L2 cache
