Originally, 8-bit 16-bit referred to the width of the data units (natively supported data type, data bus & registers) which often had different widths for the range of their addressable memory space (16, 20, 24 bits). Funny later on, processors got more & more fancier data units (32-bit, 64-bit, 80-bit, 96-bit data types but also vectorized 128-bit, 256-bit & now 512-bit data types) but increasingly simpler & condensed addressable memory space (at least the logical or virtual memory space is overwhelmingly 32-bit or 64-bit on modern processors (while physical addressable memory still has awry different limits)) so some folks switched from categorizing their processors from data units to the size of addressable virtual memory space for conveniance.
Windows 95 is a 32-bit extension to a 16-bit patch for an 8-bit operating system originally coded for a 4-bit microprocessor, written by a 2-bit company that can't stand 1-bit of competition.
From the 'if there's no electricity in it, it's off' statement, he doesn't understand them... They don't work like that. There is always electricity in the tube. There are two triodes in the tube, each used as NOT gates. Additional circuitry can be used to create a Flip-Flop, which is a sort of flipable bit or bi-stable gate..
I was disappointed he said: 1:01 well, marketing. But 64-bit is useful you can have larger memory to run more applications (and bigger applications if you have to). That's not because of marketing, that's a purely technical reason.
That vacuum tube/valve that you held up is a dual triode model, meaning that it has two independent sets cathodes, screens, and plates, so in actuality, that tube would constitute two bits... Just sayin'...

i still remember back in the 80's working with the commodore 64 you didn't always work with 8 bits at a time. you would work with smaller 4 bit segments, called nibbles, and 2 nibbles equaled a byte.
baum stamp no, it really isn’t. Web browsers are made the way they are on purpose. If there’s leftover RAM nothing is using take it and store things you’ll need later. With a lot of tabs open it will use alot more.
baum stamp my chrome uses 2GB of RAM with one tab open and no its not “user induced” because the web browsers don’t actually *need* all that RAM they use it because they can and having a bunch of tabs open shouldn’t make the problem worse. It isn’t user induced its just the way browsers are made.

The Unix time stamp is defined as a number of seconds since midnight on January 1st 1970 in the time zone of the UK, ignoring leap seconds, and assuming every day has exactly 86400 seconds. This is why you end up with date stamps in 1969, because the date somehow got stored as zero by mistake, and if your time zone is in the USA, 1/1/1970 at midnight in the UK, happened on 12/31/1969 (for me, it would happen at 7 pm on that day). Your computer translates the Unix time stamp according to your time zone and the history of leap seconds, in order to put it in a form that makes sense to you. So late December back in 69 is when Unix says it is the start of time. In the 2038, there will be another equivalent Y2K event, where 32-bit Unix times stamp runs out of capacity to store the time. It will occur on January 19th at 03:14:07 AM UTC in 2038. It will be 2^32 seconds since the time stamp began. 32-bit systems will think it is the 1970's again. If you have 64 bit capabilities, it will never run out of capacity to store the date and time stamp in any practical time scale for humanity, as it will be longer than the age of the universe thus far.

Man, this video is great. I’m taking a computer architecture course and inadvertently you helped me clarify a lot of contents I learned in class; thanks dude. Was informative and fun video to watch.
Thank you for the video and thank you Mr Alan Turing. And Freddie Williams and Kilburn for the Williams tube that was used to keep the memory or RAM for the first computers. Freddie was born in a village called Romiley in Stockport, long before I was just down the road, it’s a shame not many people know that in Romiley.
Well if we were to kep thanking we would go way back in history to ancient Indians developing complex maths and further back to stone age for the discovery of fire. All inventions r interlinked
Ahhh, vacuum tubes. Those were the days! Today, we think of Bytes in groups of 8 bits. Byte comes from BinarY TErm (BYTE) and varied. I remember when we called 8 bits an octet instead of a byte. Good video!
Great Video...Subscribed and liked. Can I make a suggestion...take the elements you've brought up and break them down a little more. Like "What is a register?"...you mention it briefly...and that's where ALL non-Video computations exist...at least temporarily..Right? Explaining everything that happens in the Registers would be cool...:)
What an awesome explanation video, I know I might won't remember this by tomorrow but is not my duty but is cool having a clue about how this devices we daily use work.
In most common cases, photos are comprised of 3 channels-red, green, and blue. "10-bit" refers to the amount of colors per channel. 10-bit means there's 1024 different color values in each channel-1024 different levels of red, 1024 different levels of green, and 1024 different levels of blue. Does that make sense?
You mentioned it briefly, but I was hoping to hear more about gaming consoles too. Nintendo 64 came out 7 years prior to AMD's release of a 64-bit CPU. How do they compare?
Good job on teaching that stuff. I'm no expert by any means, but you did an excellent presentation on a complex subject, aka you put in way more information than you really needed to. Way to multiprocess there!
I think 64 bit computers uses more memory too. Doesn't it? If you write a C program, a long double for example would take up 2, 4, 8 bits respectively on 16, 32, 64 bit processors (well, the size depends on the compiler, and if you cross compile a software for 32 bit x86 processors on your 64 bit x86_64 processor, it will use lesser memory than the 64 bit version). Not only it's in long double, but in everything. If you compile and run a program (GCC or clang permits it) to show the size of void: ``` #include "stdio.h" int main() { printf("%lu", sizeof(void *) * 8) ; } ``` It will show 32 on 32 bit CPU and 64 on 64 bit CPU Now consider that the Linux kernel is written in C, that would should use more memory that 32 bit system on a 64 bit system. The same should apply to other OS as well.
Great stuff.. I knew the basics of 32 and 64 bit computing, but now I have a greater understanding. Plus, the MacOS hint of checking application support of 64-bit is a bonus. thanks.
the thing about backwards compatibility, it's only if the CPU is specifically in the specific bit mode (16, 32 or 64-bit) if you want backwards compatibility with, let's say, 32-bit software on a 64-bit system, you need some sort of software backwards compatibility layer, like Rosetta for PPC applications in early Intel versions of OS X, that Apple has removed from macOS Catalina
I'm not sure if you still reply to questions but what are the magic numbers of computing? It seems like that 32 bit and 64 bit integer limit are magical numbers, 255 and then this with 65565 or what?
One feature that has just been activated is session recording. It allows everyone to record sessions with up to 60 minutes to achieve accurate results and ensure it doesn't miss any moments. So, how does it work? Step 1: Record the entire session = 1 hour. Step 2: Share the recording with everyone = 2.5 hours. Step 3: Preview the video record with friends = 1 day. Step 4: Download the video and review the video even without an Internet connection = 40 seconds. In addition, it supports 4K video viewing, live streaming, use HDR, 120 FPS video recording, and works on 24/7, i.e. 24 hours and 7 days. However, outdated technology does not have this feature, but the latest technology does. Thank you for listening.
Amazing explanation but the only thing I didn't get was at 7:54. That doesn't make any sense for me. 32 bits are just 4 bytes. What's the actual operation going on there?
Vaccuum tubes are not 'switches' except when being operated in saturation mode. Most are used in 'linear' mode where the grid voltage modulates the flow from the Cathode to the Anode, and can have amplification in the signal. Many tubes had only a single 'triode' in them, but dual 'triodes' were added for compactness and utility.
Perhaps I was oversimplifying, but I was really just trying to convey on and off. Adam Savage did a good video on tubes, too. That was one of my inspirations for this.
You pretty much explained the real information behind the fuzzy terms talking about X bit hardwares. However, I miss the explanation in terms of software. What does it exactly mean if an operating system is a 32b or a 64b OS?
The 1969/1970 date thing is just the Epoch/Unix time counter getting reset to Zero. Usually has more to do with a device or software having the storage that keeps track of the number being reset or erased(like loosing power on a modem). Because 01/01/1970 is "0" on that time format.
I'm always fuzzy on binary maths, but at 8:39, when it's mentioned that a 64bit cpu can do 'twice as many bits as a 32 bit cpu' - should it be 2^32 as many bits? Great video + channel. I'm new and just started watching your work.
Thanks for watching! To answer your question, no, it's not 2^32 as many bits. It's twice as many bits which results in 2^32 as many values, in this case (comparing 32 to 64).
Does 64 bit means you can represent a bigger range of number? So therefore, you can have a bigger ram? Since a register can point to more possible addresses on the ram.
Hey there, nice vid content u got there! I would like you to elaborate on computer specs such as i5,i7,i9 , their generation and what the spec for example such as i5-9300H or i7-8750X got their digits and capital from.. I already hit the bell and cannot wait for your next video :D
A BIT anoraky but the tube (valve) you were holding was at first glance a 6DJ8 or similar. Whatever the actual model number it was a double triode for sure. This allows it to switch TWO bits of information or be the basis for, I think, any logic gate - certainly AND, NAND, OR or two inverters. More bits is better innit.
A good topic is why does my 64 bit system quickly begin to slow down when the memory is sufficient and the ram is available for this not to happen? Usually after an update cycle.
A very interesting & informative video. Thank you for posting. I have a question, if my laptop is 32 bit, can I install a 64 bit Linux Mint Cinnamon o/s system on it. Thank you once again.
can you update a 32 bit app to a 64 bit app without reinstalling the app? for example, at my work some home user have Macs they remote in with and the 32 bit version of the remote access app will not work with the new OS Catalina. however, we learned that some users already had the 64 bit version of the app even though they do not recall uninstalling and reinstalling the app. i think they may have received the 64 bit version though a simple update that lasted maybe 10 seconds if they clicked approve. thanks
Yes, 64-bit versions of apps can be installed as updates. For example, when Apple updated their Compressor app from 32-bit to 64-bit, the update simply installed in place, without me having to uninstall anything.
Since Catalina has a new library exclusive for 64 bits, I would advice to install it from zero including all apps to avoid any problem, I know it’s a tough process, but it really helps. My MacBook 2015 feels like new!
Whats the best way to avoid my 32 bit software from being disabled? I'm stuck not being able to transfer my Adobe CS6 Suite and Adobe doesn't allow for product transfer on their site. I'm very partial to the software as it is my personal copy not connected to the cloud. Alternatively even with owning the disc the license can no longer be redeemed through there website. Is there a way I can move the software while carrying over the license?
@@ComputerClan If i could avoid it being disabled on my Macbook upgraded to Catalina that would be awesome. Otherwise if possible to a Windows computer.
You should avoid Catalina completely. I don’t need a need for you to move it to a Windows system (at least for several years). If you do, I’m not 100% sure what will happen with your license. My old key still works. I don’t see why yours wouldn’t.
If we allocate less data (fewer bits) for each sample, the resolution of the audio decreases. Listening to music > Hearing the smell sounds > Hearing the broken guitar. Results: Corrupted or Damaged Guitars.
Few current 64 bit processors actually have a physical 64 bit address bus, and can't address the max possible amount of memory possible for a 64 bit machine. The addressing registers may actually hold 64 bits, and such large address values may actually be used to support virtual memory (where the bulk of the actual data is held in disk storage rather than in physical memory). Also it's currently impossible to actually equip a computer with 2e64 bytes of memory (never mind what that would cost!).
Geez, I have wondered for years what the difference is between 32 & 64 bit, such, that I've taken the time to watch video's that so far haven't done much to my understanding this. Well not anymore! I don't know what gave this guy the gift to allow me to finally understand the concept. And the explanation of the binary possibilities was fascinating, or I'm a simple guy. Thanks for posting this video, I'm a bit more Edumacated now, no seriously, good vid.
By mistake I installed 32 bit version av Windows 10 on a 64 bit computer. It works fine and I wonder if it is a big deal and I should reinstall the operating system or just let it be as it is?

@@kleptotrichy "dont like it ? Then dont speak about it" WOW. People are not allowed to speak out that they don't like it huh?
@@hanselmanryanjames Have you played it recently? Its actually good now.
Man, this video is great. I’m taking a computer architecture course and inadvertently you helped me clarify a lot of contents I learned in class; thanks dude. Was informative and fun video to watch.
Thank you : ) Happy to help.
Well presentation, clear voice and rhythm of speech make this video stand out from other video which explaining the same thing
Thank you for the video and thank you Mr Alan Turing. And Freddie Williams and Kilburn for the Williams tube that was used to keep the memory or RAM for the first computers. Freddie was born in a village called Romiley in Stockport, long before I was just down the road, it’s a shame not many people know that in Romiley.
Well if we were to kep thanking we would go way back in history to ancient Indians developing complex maths and further back to stone age for the discovery of fire. All inventions r interlinked
Lord X Really how interesting. Really how interesting Really how interesting Really how interesting Really how interesting 🤔
It's very very good video. It's clear my all doubts. Great job brother.
Ahhh, vacuum tubes. Those were the days! Today, we think of Bytes in groups of 8 bits. Byte comes from BinarY TErm (BYTE) and varied. I remember when we called 8 bits an octet instead of a byte. Good video!
6:15 my stomach a few seconds after I eat an apple core
Because apple seeds are poisonous?
Really loved your unique way to explain these topics, well done. Subbed!
Great Video...Subscribed and liked. Can I make a suggestion...take the elements you've brought up and break them down a little more. Like "What is a register?"...you mention it briefly...and that's where ALL non-Video computations exist...at least temporarily..Right? Explaining everything that happens in the Registers would be cool...:)
Excellent explanation.
I always had wondered about bits and finally someone explained it in the easiest way possible.
Thank you.
Thanks for watching : )
Hey Computer nerds a bit of advise, a second or two delay at beginning of the video may help you properly start the intro.
What an awesome explanation video, I know I might won't remember this by tomorrow but is not my duty but is cool having a clue about how this devices we daily use work.
What does it mean in the photography of a 10-bit description? Does it mean 2^10 value combination of colors?
In most common cases, photos are comprised of 3 channels-red, green, and blue. "10-bit" refers to the amount of colors per channel. 10-bit means there's 1024 different color values in each channel-1024 different levels of red, 1024 different levels of green, and 1024 different levels of blue. Does that make sense?
You mentioned it briefly, but I was hoping to hear more about gaming consoles too. Nintendo 64 came out 7 years prior to AMD's release of a 64-bit CPU. How do they compare?
I’ll research it more later, but the N64 did have a 64-bit CPU. I’ll dig into the specifics when I have some time. : )
Without any second thought, this is the best explanation I have ever heard.
Good job on teaching that stuff. I'm no expert by any means, but you did an excellent presentation on a complex subject, aka you put in way more information than you really needed to. Way to multiprocess there!
Outstanding info video....feel like i am going back to school !!!! Subscribed !!!
Thank you : )
I think 64 bit computers uses more memory too. Doesn't it?
If you write a C program, a long double for example would take up 2, 4, 8 bits respectively on 16, 32, 64 bit processors (well, the size depends on the compiler, and if you cross compile a software for 32 bit x86 processors on your 64 bit x86_64 processor, it will use lesser memory than the 64 bit version).
Not only it's in long double, but in everything. If you compile and run a program (GCC or clang permits it) to show the size of void:
```
#include "stdio.h"
int main() { printf("%lu", sizeof(void *) * 8) ; }
```
It will show 32 on 32 bit CPU and 64 on 64 bit CPU
Now consider that the Linux kernel is written in C, that would should use more memory that 32 bit system on a 64 bit system. The same should apply to other OS as well.
yes simple the bigger the bit the more memory you need cuz its more detail and more detail means more data and more data means more memory jajajajaj
How could I missed till now?
This was a great video
Thank you very much.
6:11 may you please show the audio used in that part?
Great stuff.. I knew the basics of 32 and 64 bit computing, but now I have a greater understanding. Plus, the MacOS hint of checking application support of 64-bit is a bonus. thanks.
Fantastic video, thank you for this! Really well explained, and good quality production.
the thing about backwards compatibility, it's only if the CPU is specifically in the specific bit mode (16, 32 or 64-bit)
if you want backwards compatibility with, let's say, 32-bit software on a 64-bit system, you need some sort of software backwards compatibility layer, like Rosetta for PPC applications in early Intel versions of OS X, that Apple has removed from macOS Catalina
I'm not sure if you still reply to questions but what are the magic numbers of computing?
It seems like that 32 bit and 64 bit integer limit are magical numbers, 255 and then this with 65565 or what?
One feature that has just been activated is session recording.
It allows everyone to record sessions with up to 60 minutes to achieve accurate results and ensure it doesn't miss any moments.
So, how does it work?
Step 1: Record the entire session = 1 hour.
Step 2: Share the recording with everyone = 2.5 hours.
Step 3: Preview the video record with friends = 1 day.
Step 4: Download the video and review the video even without an Internet connection = 40 seconds.
In addition, it supports 4K video viewing, live streaming, use HDR, 120 FPS video recording, and works on 24/7, i.e. 24 hours and 7 days.
However, outdated technology does not have this feature, but the latest technology does.
Thank you for listening.
Amazing explanation but the only thing I didn't get was at 7:54. That doesn't make any sense for me. 32 bits are just 4 bytes. What's the actual operation going on there?
was that tune you played at 6:05 more than a feeling by boston
Correct-o
You could teach a masterclass to TH-camrs on clear pronunciation and vocal post processing. Really pleasant to listen to
Vaccuum tubes are not 'switches' except when being operated in saturation mode. Most are used in 'linear' mode where the grid voltage modulates the flow from the Cathode to the Anode, and can have amplification in the signal. Many tubes had only a single 'triode' in them, but dual 'triodes' were added for compactness and utility.
Perhaps I was oversimplifying, but I was really just trying to convey on and off. Adam Savage did a good video on tubes, too. That was one of my inspirations for this.
Unfortunately Windows does not offer a 16-bit Virtual DOS Machine on 64-bit versions. You can only run old DOS software with 32-bit Windows versions.
You pretty much explained the real information behind the fuzzy terms talking about X bit hardwares. However, I miss the explanation in terms of software. What does it exactly mean if an operating system is a 32b or a 64b OS?
The 1969/1970 date thing is just the Epoch/Unix time counter getting reset to Zero. Usually has more to do with a device or software having the storage that keeps track of the number being reset or erased(like loosing power on a modem). Because 01/01/1970 is "0" on that time format.
I'm always fuzzy on binary maths, but at 8:39, when it's mentioned that a 64bit cpu can do 'twice as many bits as a 32 bit cpu' - should it be 2^32 as many bits?
Great video + channel. I'm new and just started watching your work.
Thanks for watching! To answer your question, no, it's not 2^32 as many bits. It's twice as many bits which results in 2^32 as many values, in this case (comparing 32 to 64).
Does 64 bit means you can represent a bigger range of number? So therefore, you can have a bigger ram? Since a register can point to more possible addresses on the ram.
Hey there, nice vid content u got there!
I would like you to elaborate on computer specs such as i5,i7,i9 , their generation and what the spec for example such as i5-9300H or i7-8750X got their digits and capital from..
I already hit the bell and cannot wait for your next video :D
A BIT anoraky but the tube (valve) you were holding was at first glance a 6DJ8 or similar. Whatever the actual model number it was a double triode for sure. This allows it to switch TWO bits of information or be the basis for, I think, any logic gate - certainly AND, NAND, OR or two inverters.
More bits is better innit.
A good approach to explain concept, as a developer i really need to understand this things. Thanks for a great video.
i am so glad i found the likes of theengineerguy, TechMoan, 8-bit guy and now 🤗🖒Computer Clan👍🙃
I could also recommend Technology Connections then! Amazing content creator
1:30 Nostalgia!!! I loved that little game. I dont even remember its name.
That is more than what I have expected from this video :)
Not an Apple user, but the insides of the Mac at 2:10 are beautiful. Useful? Not so much, but definitely nice to look at.
If this comment doesn't make sense, that's because it should have been on another video...
Weird! Must be a TH-cam bug because someone else said they were having the same problem. I noticed some bugs on TH-cam today, too… hmm…
Just throw in some quantum computing and then we’ll really be confused
instead of a 1 or 0
it's 1 to 0, with EVERYTHING in between
(might not be correct)
Finally someone with real difference between 32 and 64 bit.
Good job.
Sir I have a question , practically is there any device for converting 32bit instruction into 16bit instruction practically ?
A good topic is why does my 64 bit system quickly begin to slow down when the memory is sufficient and the ram is available for this not to happen? Usually after an update cycle.
Thanks for this informative video, if you explain how quantum computers work in another video would be nice to learn.
I have been learning about them lately. I might make a future video on them. We’ll see…
Sega genesis : " I have blast processing. "
A very interesting & informative video. Thank you for posting. I have a question, if my laptop is 32 bit, can I install a 64 bit Linux Mint Cinnamon o/s system on it. Thank you once again.
Typically, no. You will need a CPU that supports a 64-bit OS.
@@ComputerClan Thank you very much for your quick reply, :-)
I tried installing Windows Vista 64 bit on a 32 bit Dell Dimention XPS T600r and it always stopped me from booting into the OS.
Why we can`t have 4 bit extensions with 8 bit extensions with 16 bit extensions with 32 bit extensions with 64 bit extensions?
can you update a 32 bit app to a 64 bit app without reinstalling the app? for example, at my work some home user have Macs they remote in with and the 32 bit version of the remote access app will not work with the new OS Catalina. however, we learned that some users already had the 64 bit version of the app even though they do not recall uninstalling and reinstalling the app. i think they may have received the 64 bit version though a simple update that lasted maybe 10 seconds if they clicked approve. thanks
Yes, 64-bit versions of apps can be installed as updates. For example, when Apple updated their Compressor app from 32-bit to 64-bit, the update simply installed in place, without me having to uninstall anything.
Since Catalina has a new library exclusive for 64 bits, I would advice to install it from zero including all apps to avoid any problem, I know it’s a tough process, but it really helps. My MacBook 2015 feels like new!
I need more about the vacum tube
Detailed explanation! Thanks a lot! 👍
Whats the best way to avoid my 32 bit software from being disabled? I'm stuck not being able to transfer my Adobe CS6 Suite and Adobe doesn't allow for product transfer on their site. I'm very partial to the software as it is my personal copy not connected to the cloud. Alternatively even with owning the disc the license can no longer be redeemed through there website. Is there a way I can move the software while carrying over the license?
When you say ‘move’ what do you mean? To Catalina? To a new Mac?
@@ComputerClan If i could avoid it being disabled on my Macbook upgraded to Catalina that would be awesome. Otherwise if possible to a Windows computer.
You should avoid Catalina completely. I don’t need a need for you to move it to a Windows system (at least for several years). If you do, I’m not 100% sure what will happen with your license. My old key still works. I don’t see why yours wouldn’t.
@@ComputerClan thanks a lot for the input that's kinda where I decided to stay at this time.
Very clear information, thanks and kind regards.
If we allocate less data (fewer bits) for each sample, the resolution of the audio decreases.

Great video! Thanks I'll add this to my class references for students. :)
Great video that i totally already watched just seconds after it was uploaded
Amazing didactics. Good job mate.
A.J. Soprano! who would ever thought, you've came a long way man, Tony and Carmela most be really proud.
When was the last time you talked about this? 2013? Yeah it’s been a long time...
Few current 64 bit processors actually have a physical 64 bit address bus, and can't address the max possible amount of memory possible for a 64 bit machine. The addressing registers may actually hold 64 bits, and such large address values may actually be used to support virtual memory (where the bulk of the actual data is held in disk storage rather than in physical memory). Also it's currently impossible to actually equip a computer with 2e64 bytes of memory (never mind what that would cost!).
Thanks! This is a really good vid about this topic. Now i finally understand :)
if all my college professors could explain stuff like this i think me and my friends would have graduated a bit too early... good presentation..
Thank you : )
subscribed within a minute..thanks for the crazy info.
You’re welcome ; )
Geez, I have wondered for years what the difference is between 32 & 64 bit, such, that I've taken the time to watch video's that so far haven't done much to my understanding this. Well not anymore! I don't know what gave this guy the gift to allow me to finally understand the concept. And the explanation of the binary possibilities was fascinating, or I'm a simple guy. Thanks for posting this video, I'm a bit more Edumacated now, no seriously, good vid.
What does simultaneous support for 32 and 64 bit practically means in a pc/ laptop? That 32bit support pushes back 64bit performance?
By mistake I installed 32 bit version av Windows 10 on a 64 bit computer. It works fine and I wonder if it is a big deal and I should reinstall the operating system or just let it be as it is?
