The jump from dialup to broadband was unbelievable at the time. Instead of incremental upgrades, it was like going to the moon after inventing the wheel.
Just going from a 56k dial up to an 64k isdn connection was a major upgrade. The connection was just so much more stable. Then the dsl 128/64 came and no one has been looking back since. But today with at 100mb line you can do almost anything. Its crazy to think about that its only about 20ish year since we had 56k dial up.😂
I remember my 56k modem download speed was about 4kb/s and then I got broadband and it jumped to about 200kb/s. I convinced my dad that it would be worth buying so my grandma would stop complaining that the phone line was always engaged. 😅
You are hands down the best channel to ever explain anything computer or networking related! I’ve been waiting on a video to explain bandwidth for so long
Professor PowerCert breaking character and laughing made me laugh as well and made my night. I understood EXACTLY why he chuckled when talking about dial up connections in the 90's.
This is why I am a paid member to your channel; I continue to be able to do deep dives and further learn. I work in I.T. and on my lunch breaks, I enjoy watching your videos to help my understanding be even more confident.
That laugh at 3:56 is amazing. As someone who used the disk drives to get a free account ever 45 days, to now someone who gets upset when there is a buffer after waiting 1 second...it truly is a crazy thing to show the growth of technology.
Hey man, been a fan for 7 years, ever simce you helped me pass my A+ 901 and now you're helping me with my Network+. It was really good to my heart to hear you laugh.
That laugh was definitely contagious when he brought up AOL 😂 amazing content, you keep explaining things perfectly and the animations add so much feedback. Moar uploads please!
3:58 LOL at you laughing when talking about AOL. I had a 56k modem back in the day and remember all too well how slow a dial-up connection was. It was painful! Kids today don’t know how good they have things!
Conversions from mbps to MB/s: 100 mbps: 12.5 MB/s 500 mbps: 62.5 MB/s 1000 mbps: 125 MB/s Which means for instance that with a 1000 mbps connection, it would take at least 8 seconds to download a 1 GB file. Some ISP sort of scam people by advertising their speeds as MB/s without converting from mbps.
Been following your excellent channel here for years. So happy to see that it has grown to 1.51M subscribers. Congrats! PS My first modem was a 1,200 baud dialup connection. I am so old now that rocks have started calling me, "dad". 😄
don't forget the server speed also matters. its like having this water pipe from a video which can transfer large amount of water but the tap in the other side is barely getting water out.
Asymmetrical speeds are indeed the norm when talking about coax and DSL connections. However fiber are, depending on region ofc, often symmetrical. Also fun fact. 1G is not actually what you get over gigabit networks with default configurations. Because of overhead actual maximum theoretical throughput is more like 940 mbps.
Solid video as always!!. I remember using dial up connection when i was around 12 years old, it was so painful watching a music video on launch, it would take like 30 minutes or something like that to watch a 3 to 4 minute video lol.
It's more accurate to refer to 'download rate' and 'upload rate' rather than 'speed' because speed technically involves distance over time, like km/h. Internet bandwidth is actually a rate, measured in bits per second, so it's more about how much data is transferred per unit of time rather than how fast (e.g. heart rate is measured in BPM or beats per minute).
Watching this now on a laptop (wired) with ONLY 50mbps plan (downgraded from 100, asymmetrical and coax) having 3 personal smartphones, mom's phone, dad's phone and tablet and heavily streaming on a 4K smart tv WITHOUT ANY issues of bufferings and disconnections. Simple and effective solution was enabling my router's QOS function and connecting most devices to 5ghz band, so it really helped to manage and allocate the bandwidths. After all, it's just a matter of 'what you ONLY NEED' and not those unnecessary, overkill high bandwidth speeds.
Liked the video. Great analogy, illustration, and humor (at AOL) but could have covered 2 other pieces of determining internet speed, latency and ping timing. Maybe next time. Thanks
Please make a virtual lab with linux and linux servers and its different codes. You are among the best online network teachers I've ever met, even the ignorant get a better understanding with your different tutorials.
As an addition, if you purchase an, let's say, 100Mb/s internet connection, you're not always guaranteed to have exactly this download speed when downloading something. It usually depends on what speed the server is capable of and allocates to your current connection. Also some servers / file-hosters only provide higher speeds when buying a subscription. I guess an aspect some people are not aware of.
Pps should also be mentioned. There are cases where that causes issues. Also, it is speed theoretically. A higher bandwidth means a full packet will arrive faster, meaning the connection is faster.
My home used to have DSL. Then we upgraded to coaxial cable (DOCSIS). I forgot what speed we had with DSL but we had 50 Mbps download and 10 Mbps upload with coaxial cable. Nowadays we have 500 Mbps symmetrical fiber to the home (FTTH). Its great.
It would be nice it you talked about latency, how you could have tb of bandwidth but the internet can still feel slow and unresponsive due to high latency
Like most discussions on bandwidth you are missing out the most important bit ! All internet traffic has TWO ends. If the web site you want has a "100Mbps" connection to his ISP then he can only send about 10 to the Internet - as you say - which means that you are only going to receive 10 - EVEN IF YOUR END HAS A 1000Mbps SERVICE. High bandwidth is only useful if you are sharing it between lots of local users (or downloading 200 videos at once - you know who you are!). For even the largest family 100/ 150 MHz will suit because real-world delays elsewhere will limit you to less.
And from this video, I now better understand link aggregation! Combining multiple ethernet ports makes for better bandwidth! "Bigger pipe to push more water through"! Also, definitely a first time I heard you laugh in one of your videos Broke the serious immersion for me which made it more fun, hah!😄
4:00 if you can believe it, I started with a supra 300 baud modem on which I 4:02 ran a board system with. I upgraded every time a new speed came out ending with 56K before switching to cable. Oh the good days.
It depends on the internet service. Services like DSL/Dial Up have limitations on the distance. So if you're too far from the ISP's central office, your speed will be slower due to the nature of those connections. For services like fiber, I believe they can just adjust the speed on the port that services your connection.
1. AOL. Yep, I remember those days. 2. Would you please go into the "channels" of a modem? The upload is precisely the issue I have and I'd love to know what the Modem tells us in terms of channels, DOCSIS, etc. That would be interesting. Sorry, if this was discussed before.

The jump from dialup to broadband was unbelievable at the time. Instead of incremental upgrades, it was like going to the moon after inventing the wheel.
Agreed
I remember DSL which was sort of a transition line. It was a dialup that was always connected but very low bandwidth. Nothing like today.
Excellent analogy!

Did you know that he has a full course on this channel (A+)? He's amazing for sure
@@MwishaLudack Whaaaat!!? I honestly didn’t even know that
That laugh at 3:56 is so contagious😂
I laughed also, oh the aol days😂
Thought I had a disconnection or buffering for a moment, until I backtracked and heard it 😄...TY AOL-OL!
I could feel my MSN window vibrate in the meantime
It was a sneeze actually
It was a laugh
Professor PowerCert breaking character and laughing made me laugh as well and made my night. I understood EXACTLY why he chuckled when talking about dial up connections in the 90's.

I remember, I was joyful and very contented every time it hits 45kbps 😆, average 'speed' was about 35kbps to a low 28!
This video is gold; it doesn't need to cut the part where he laughs 3:56
Conversions from mbps to MB/s:
100 mbps: 12.5 MB/s
500 mbps: 62.5 MB/s
1000 mbps: 125 MB/s
Which means for instance that with a 1000 mbps connection, it would take at least 8 seconds to download a 1 GB file.
Some ISP sort of scam people by advertising their speeds as MB/s without converting from mbps.
I think you'd have to factor in some overhead? I mean, transferring a 1GB would require greater than 1GB x 8 bits, wouldn't it?
@@toby9999 yep that right
תודה!
Thank you Mendel!

@@PowerCertAnimatedVideos you're most welcome! Keep up the excellent work that you are doing here.
Thanks! This explains it perfectly. Some people get 5 mbs or 5 mbps mixed, they are different values.
Yes true
Yes. 1 MB/s = 8 mbps
As always, a very well presented and thought out presentation. Dont you miss the heady days of dial up and 386 and 486 PCs - said nobody ever
WHAAAAATT. I tried to slide down that and couldn't, honestly impressive work on your part consistently releasing content like this!!!
Another good video. I love how you laughed when talking about AOL. So true. Remember Juno email? The days when the internet was dial up.
Very well explained and illustrated.
Thank you.
don't forget the server speed also matters.
its like having this water pipe from a video which can transfer large amount of water but the tap in the other side is barely getting water out.
thanks for the lesson!
side note: 3:54 bless you!
😂😂
did he sneeze or was just laughing at the speed? :D
@@zmertzi i heard a sneeze.
I was laughing, not sneezing.
@@PowerCertAnimatedVideos either way, bless you for the lesson, and the misheard sneeze.
Best tech vids on youtube, seen them all
Waiting for a long time. Thank you for uploading
Thanks for making this video. I spend an extraordinary amount of time explaining this to customers
Love you broke character on this one!
Nice video! I think a video explaining Throughput will be a great complement for this one
Thank you so much.... you know i had subscribed hardly 20 channels and your is one of them...

I used to think the voice over was AI generated until I got at that point 😂😂😂
you are the father ive always needed
simple and coherent video, also enjoyed the suppresed laugh at AOL 😂
Good video.👏
The AOL part where you laughed was funny.👍😂
3:54
Had gotten through the pain, we can enjoy the hilariousness now.

Your illustration is awesome, can I ask what software you are using to create these animations in video?
Thanks. Powerpoint.
Hi do you plan on remaking the comptia A+ study guide? Your videos are very detailed, entertaining, and very easy to understand.
Informative and Thorough, Thank you.
I've been thinking you should make troubleshooting tutorials. It'd be great with your simple and straightforward explanations
Good explained thank you ❤❤
I love how you kept breaking up during the AOL part 😂

excellent video as always.
1:41 this is exactly the analogy I use for my clients!
Funny thing with evolution is that one day someone may laugh over 500Mbps or 1Gbps bandwidth.
Nice description btw!
Thank you as always for the informative videos.
I used to say the voice over was AI until he made a laugh at 3:55 😂😂😂
Excellent lesson ❤❤
you are so great explainer 💕💕😊😊
make more and more videos on vital networking concepts
One the most important thing you forgot to mention is, how much speed is enough for which use case.
Just amazing as always
Awesome explanation.
It would be nice it you talked about latency, how you could have tb of bandwidth but the internet can still feel slow and unresponsive due to high latency
May i know the tools you used to create such wonderful videos
Lmao. He broke character! Love it 😂😂
Great video but I wish you would have spoken about the transfer rate of the source as that has a big impact on how long it takes to download content.
hes back
Very well explained
Awesome ! as Always ... Thanks so much.
You made it easy to understand
I Love your teaching ♥️
Great explanation. Ahh the good ole AOL days. 😅
Thanks for explaining. It really helps
new powercert video!
Thanking for explaining this.
Cristal clear concept ❤

Thanks, maybe you can explain soon between broadband internet and dedicated internet
interesting
4:00 if you can believe it, I started with a supra 300 baud modem on which I 4:02 ran a board system with. I upgraded every time a new speed came out ending with 56K before switching to cable. Oh the good days.
Awesome class 🎉
Finally after long time ❤
Yes Back to World connect.
Hi, thanks for this video. Can you also explain how bandwidth sharing works at home and at office? Thanks!
always on point ,
by the way can you post a video about cyber forensics explanation
Thank you for your videos. New sub here.
Thankfully, free (and oftentimes as open-source) multimedia compression applications exists.
How ISP's control bandwidth for each package? is there any software or hardware that limits the speed?
