Is PS/2 or USB Better for Keyboards and Mice? 

never found the 'any key' :(

Ikr it funny cause it not there

or just click a mouse button? plot twist

It sounds like a joke nowadays, but in the days before PS/2 it was actually pretty useful. The predecessor of PS/2 was hot plug capable and many PCs did not use but some rather obscure key-presses to get into the BIOS setup. If the system did not show you the necessary key by default and you didn't know the correct key, you simply pulled the keyboard plug out and started the system. Then you got the infamous "No keyboard found. Press any key to continue." message, often followed by something like "Or press to enter setup." Then you just plug the keyboard back in and continue. We had some systems where provoking this error was the only way to get into the BIOS setup. Ah, those were the days...

Beaker those were the (bad) days

Yes

I love this.

ThatLonelyFox you spent way too much time on this for just 100 or so likes

FUCK YEAH!

da, gamers needs separate keyboard and mice ports like PS/#, that directly rule CPU.

A PS/3 would be perfect as a dedicated USB port with more features and backwards compatible. or Maybe special drivers that can make USB send System Interrupts.

we'll put valve right on it.

@@UsmanSiddiq1 Yup, many people too lazy to use the USB port in the back, and only rely to use front panel USB or use USB hub in their desk lol

@@da_pawz Really? Just about all my back ports are used - I'd welcome freeing one from my keyboard. Almost seems like a waste of a slot, honestly.

With and without Ps2 Rate running I presume ;) Kind of strange this about latency didn't came up in the video.

People who claim that PS/2 is superior speaks straight bullshit, especially if they bring up latency. The difference is so unsignificant that it doesnt bring an advantage. In compatibility, PS/2 is very superior tho

I agree!

Poll rate is 1ms for USB1 and 0.125ms for USB2. Hardware and drivers are free to do worse than that, of course.

@@tormodhag6824 I disagree. N-key-rollover is the biggest (and frankly, only) selling point I've seen people mention. And in my opinion it's a decent one. Especially if your USB keyboard comes with a PS/2 adaptor.

Pros and cons to everything in life really.

PS/2 devices can be hot-swapped, just not all the time. I've experienced times when doing so causes the keyboard or mouse to not be recognized until you reboot, but instances of it causing damage are very rare. And a lot of times you can get away with it with no problems.

VWestlife careful, VW, saying that kind of thing is liable the get a $user to break something.

usually you can buy PS/2 splitters, but sometimes said splitters are unreliable.

Officially not hot swappable, but rarely causes any problems if you do. If it was plugged in and already recognized at boot time, then most of the time you can unplug and replug without reboot.

Thats some usefull info

Had this happen last week, at startup, with an old computer. Good thing I have a spare ps/2.

sadly my G15 logitech doesnt work with the USB adapter to PS/2 Nor my mouse m100 normaly usb or the g9 mouse none of them :( i waste my money.

@@PescaitoFrito usb adapters aren't always wired the same and are only supported by specific keyboard. They were a transition technology and the keyboard would need to be able to run in either ps2 or usb mode, I doubt you'll find modern keyboards that support this. If it doesn't come in the box it's not supported. PS2 isn't any better than a quality USB keyboard. Back when keyboard first went USB they were all crap you could clearly see the difference, it was a few years before you started getting 8+ key rollover and 1000hz polling rates. These days you can't tell the difference and the benefits of USB outway PS2. However I'm still glad I have a PS2 port, I haven't used it for years but I like having the option. Also who cares if ctrl+alt+del doesn't work, your restarting your pc anyway at that point or you could just replug the usb keyboard.

@@Commander_ZiN So for games specifically requiring speed and key combinations of more than 1, is it better to use PS / 2 or USB?

31337 Clan Certain emulators, dual booting and other stuff I do can cause you to have driver glitches with Windows 10 and when that happens you can't use USB mice or keyboards that require drivers.

What are you talking about? I've used Windows 10 since its release and it has never rejected my keyboard or mouse or had problems with connectivity or response. I hate Microsuck as much as anyone but ironically, the connectivity has never been an issue for me.

I do weird things with Linux and emulators that Windows 10 doesn't like, it really isn't a big deal though because it's easily fixed with a Ps2 keyboard. My main problem with windows 10 is the constant forced updates that change my settings and always seem to make something stop working.

Same here, the forced update made my bios got glitch regarding USB ports

Wouldn't it of been better to use a USB hub and get more ports rather then save just one by paying money for a adapter? No sense...

Krytern UK decent powered usb hub = $20. Usb to ps2 adapter = $0.5 (or free since most have one somewhere).

Do you still get nkey rollover this way?

Damian Anlauf Using an adapter means that you get the worst of both worlds, so I'd guess not.

qwertyuiopzxcfgh I'm not so sure because considering how PS/2 works, a USB to PS/2 adapter should not work at all, at least not a passive one.

Micky strange to find a Russian time here

actually usb stands for usabella 2.0 or usabella 3.0 which is a lot more annoying

Well you cannot use them no more as PS/2 don't exist anymore hence that is why all modern day devices use USB as USB is much more durable and robust

tris Do you have a PS/2 port where I can plug my tool? If not, I think we are incompatible.

PM Salvo: Or not, this was true on especially old devices, but "recent" (2000+) motherboard are fine if you switch them.

Tom F Wow, I didn't had that when I had a PC back in 2003. Do you know if the ports are still colored green and purple? Because it would be weird if they still color coded the ports if they are interchangeable.

Mine only has one port and the it is colored half green and half purple.

ZNemerald on most modern boards its just a solid colour and can be used for the keyboard or mice

If you really are that desperate, a small USB hub would work.

This is legit , especially lately , when every mobile device moves to less and less ports .

Get a laptop with 3 USB ports. 3 aren't enough for you ??? Get a gadget that makes more USB portes from 1.

I have a usb hub so it isnt a problem ;)

3 is just enough ports for me, but if I ever wanted to connect another thing to a port I'll need to swap something out. I usually don't need more than three but if I do it's an annoyance.

The students at my old middle school use to unplug the keyboards and mice. The IT guys were always in alcoves

Broken Bucket Yeah same at my old school too.

Francisco Santos maybe.....😂

Yeah.... USB can do that too though.

No. I'm not talking about any kind of sleep or hibernation, I'm talking about Shut Down (fast startup can also be turned off). I've never seen an option for USB to do this.

I have a always on option for USB in my BIOS. I can turn on pc by a keyboard press from a shut down state

and how do u do that shit

USB Can do that too from shutdown. It's an option in BIOS as long as your computer detects that the USB device is a keyboard

Roman Bukins ... It's not yet but usb c will be the next thing unless something else comes out

Coaxial

Patrick Neary explain

what do you mean by "secure" ?

James TheGamer usb devices need to have signed drivers associated with them when connected. You can inject malware or tell a system to get fake drivers which can then grab viruses and such. Which is why you should never use a USB key that you found on the ground.

Usb ports can be used for other things such as flash drives so things that have a USB port can put unwanted files onto your computer. Ps/2 ports will not allow files to be transferred. This is why IT workers and government buildings will use ps/2

There always is a workaround. You could just emulate a PS2 keyboard, and your done. This is like BasUSB but with ps2 edit: so if you're afraid of USB ports, then better not use computers at all :b

This holds even more truth on todays multithreaded systems. However, as a coder, I find polling aesthetically ugly. But that's a problem in my head, not the pc.

Yeah, sure, fps, but that's just only one particular use. For most uses the interrupt system should be better than polling system. However, we are (sadly) driven by industrial efficiency, rather than user focused. So the predominant idea is to produce more computers with the simpler factory lines, which includes less different ports, if possible only one (some computers are so useless that don't even have an ethernet port)

@@alfredomartinezcaceres3936 None of this is true though, as USB's polling (even USB1.1 with its 12Mbit/s) is still faster than PS/2's interupts. The total time USB takes to poll and process a scancode from a USB keyboard vs the time it takes a PS/2 keyboard to send its scancode using an interupt is in the range of 15-100 times faster than PS/2 (depending on USB version). Besides that, most PS/2 ports on computers the last decade or so are just connected to the USB controller on your pc, which has a backwards compatible mode for PS/2. This means for most people that have used PS/2 keyboards the last decade or so, they do not have interupts.

For keyboards it makes sense, as it was designed for, for mice it might make less sense sending 100 or even up to 200 interrupts. I'm not knowledgeable enough to judge. Early ps/2 mice, like the microsoft scroll wheel mouse, did only send 31 interrupts and you could change to a max of 62. Later mice did 100 by default, with easy changeable to 200 in the mouse properties

I have an active PS2 to USB converter since half of my hardware doesn't have PS2 ports. (this thing : www.amazon.com/Sewell-Active-Adapter-Keyboard-Mouse/dp/B008J56RVY )

A company called Unicomp, Inc., still produces the model M from IBM's original tooling. They also make a USB version.

To make matters worse, some motherboard in my experience doesn't accept inputs from certain USB ports during boot, much less USB hubs.

Amen

A serial mouse? Sir, you make me proud!

Have you tried using the COM-port for LAN? I tried once, it took 5 minutes to send an "end turn" of Heroes of might and magic.

Xd

Same here

10000 bytes per second, just to send a single byte signal. that's 10k operations per second. if we convert that to milliseconds, that's 10 operations a millisecond (aka 0,1 milliseconds per operation). my monitor refreshes every 2.4 milliseconds. I think I can handle a 0,1 millisecond operation, by the time my screen has refreshed i could have pressed 24 keys, at least if i was from X-Men.

PS2 isn't superior at all. It is the same than usb 1.0 only if you push one key at a time, but if there are more more keys pressed, it's always worse. This is because one USB 1.0 packet takes equal time to transmit as one PS2 packet, but the ps2 packets only hold one key on/off command, and the USB ones hold up to 6 key states plus the ALT/SHIFT/CTRL/WINDOWS states (left and right ones), totalling 12 keys. (and that's just usb 1.0, it gets faster on the later versions.) Also, on PS2 , the message of a key release , takes twice the time than the message of pressing a key. The lack of speed is by far more important than any other usb latency problem. I used as reference Ben Eater's video "The USB Protocol"

@@JackPorter 10Kbps is 10,000 Bytes per second now? No, 10KBps would be 10,000 Bytes per second (notice the b vs B, bit vs Byte, seems like a small difference but it matters here :P) PS/2 doesn't just send a keystroke, it sends a scancode. Each key press generates a scancode, each key release also generates a scancode. Most keys have a 1 Byte scancode generating around 10 bits of data, some keys have a 2 Byte scancode. So in reality the bandwidth isn't 10,000 keys per second but more like 600-700, which still seems higher than a human would type but isn't anything special in terms of speed. Btw, your monitor doesn't refresh every 2.4 milliseconds, or it would have a 461.7Hz refreshrate, many times higher than even the best HDMI standard can handle.

James Valentine how?

@Tiny Metal Tube USB is for more than just HID, imagine what happens to the shared bus when you're cruising through an external drive (as an example, doing routine backups) or a webcam for streaming. Those high bandwidth devices running full steam will choke out nearly all other devices or more likely be throttled by the hub and suffer loss in performance. It's a /universal/ serial bus, not just a slot to stick overpriced flashing RGB keyboards into. It's bad to tell people there really isn't a need to consider PS/2 over USB when there are very clear and important advantages to reviving the work-horse protocol, and as someone who has had to work with USB hardware I absolutely despise how cluttered and bloated the whole thing is from the chips all the way to the kernel USB stack; dealing with it makes everything slower and particularly affects mobile and embedded devices badly (don't forget the use case of USB isn't limited to desktops with enough cycles to make it imperceptible under normal loads). PS/2 certainly had issues, but USB took it all and made it suck then suck faster, and now it sucks fast at much higher amperage for extra fun. I can't wait to see how many OEM PSUs fail when the charging ports proliferate on prebuilts and laptops that should never have them and some cheap device actually tries to pull 2.5 or 5A out of a common Dell or HP. (For even more fun, imagine what all that rippling on the USB power rails is and/or can do to all the devices on the bus!)

I have never heard of hot swapping ps2 and you can use usb hubs to increase your usb ports, they don't slow down the USB transfer speed

It's actually been a thing for a while, if a given bios is compatable with it. Plug in PS/2, hear a beep, and it's ready to go. No hassle, no waiting.

usb hubs may damage your mobo by extra heating or sometimes by static

@@Nobody-eg4bi decent mobos have static protection on all ports, there are usb expansion cards, you can put like 4x usb 3.0 in a pci-e slot.

@@Humaricslastcall There are very few BIOS's which actually support this though. Mostly because USB has become so prevalent that there's simply no need to even include a PS/2 port, much less provide additional functions for it. Systems often come with more USB ports than most people will ever need to use. I have USB ports on the front, on the back and on the top of the machine. Of which I use about 6 at most, and that's if I'm using the Occulus Rift (3x USB 3.0 for Occulus, 1x Mouse, 1x KB, 1xGamepad). I still have another 6 unused ports in total.

2 dead memes in one! Nice, kid!

The big 5 pin connector 'DIN' is the normal variant, PS/2 uses a 6 pin 'mini DIN' connector. They use the same PS/2 protocol, the only reason the smaller mini-DIN has 6 pins is to (optionally) combine both the mouse and keyboard signals into a single connector with some motherboards. By default both DIN and Mini-DIN PS/2 connectors only use 4 of their pins.

I don't think Motherboard company's build PS/2 connectors on their top-of-the-line motherboards just to please a small group of IBM lovers.

most motherboard companies actually have KB/M PS/2 combination ports on their motherboards, even on some high end ones. But not the majority, you are right. What's less common is separate ports for KB/M PS/2 (one port for mouse and one port for keyboard).

PS2 keybaord much better for gaming, unless you have a special Gaming keyboard. I cna press 7-8 keys at the same time and they all work, while on a normal USM keyboard it starts beeping with just 2-3 key presses at the same time.

@@Jeymez wrong, ps/2 has the lower input lag, they at the end stays equally equivalent because ps/2 cant run at 1000hz otherwise ps/2 would be far superior. tldr- they have same input lag basically even tho ps/2 runs native at 125hz. if you overclock to above it, for example 200, 250, you have a faster mouse response than usb.

@@ShadeCaBr Nope, PS/2 actually has a higher input 'lag' than USB, even USB 1.1. While PS/2 does support interrupts, the time PS/2 takes to send a keyboard scancode is 15-100 times longer than it takes USB to poll the keyboard and receive the complete scancode. PS/2 has a clockspeed of 10kHz up to 16.7kHz, not sure where you're getting 125Hz, a quick read of the PS/2 technical reference shows that at least since 1991 it has been 10kHz. Especially when you consider that a USB frame sent from the keyboard is much longer than a PS/2 scancode and USB still is significantly faster... Compare it to a bus and a bicycle, the bicycle stops by every minute while the bus stops by every 5 minutes. The bus travels to the destination in 10 minutes while the bicycle takes an hour. So even though the bicycle comes by more often (each minute), the bus is faster.

USB does not have a way for a device to send an interrupt, ever. It physically does not support that so even if the OS supports it, the hardware cannot. The only way for USB to cause an interrupt would be for the CPU to poll the keyboard/mouse, process the data and then have the CPU throw an interrupt for no reason. Memory mapped IO is a general term in hardware, as of USB4 this is not supported nor has it been. The functionality you describe is basically how USB works, a device is polled, the response is stored in memory and the CPU processes it. I have not ever seen a USB controller that has an interrupt signal output, so this is purely timed by the CPU.

you should be happy

He already did a video on that.

Lossy audio compression (mp3, ogg) makes audio files smaller by removing sounds that the human ear can't hear, and at lower bitrates it starts removing sounds that you probably won't notice. Lossless audio(wav, flac) doesn't remove any sound but a codec like FLAC still compresses the audio (like a zip file). Some people say they can hear a difference, but I'm not sure anyone has been able to tell the difference between 320kbps lossy vs lossless audio in a proper experiment.

teslaTrooper There is a quite small difference in soundstage representation that I noticed, but it could be all in my head.

Wrong. Compression in flac works much like ZIP files. The compressor divides the song (or whatever) in pieces called samples. Then it searches which samples are EXACTLY the same and gives them an index code (for example S1), it creates a table at (I think it's) the end of the file with every index code and the content. Then everytime it detects that same sample it changes the whole sample by a simple "S1" which is many times smaller than the actual sample. And it does the same with every sample that repeats. The more samples that repeat the more compression the file gets. This means that the flac file is exactly the same as the original in terms of sound quality. THERE IS NO NEGLIGIBLE NOTHING. The file sounds exactly the same. It's the reason why electronic music can get much more compression in FLAC than "analogic" music. In analogic music any slight vibration/difference in tone/difference in volume causes that even though 2 samples may be 99.999% identical however that 0.001% makes them different thus not compressed. In electronic music sounds are digitally produced thus 2 sounds that were intended to be exactly the same will be exactly the same meaning more chances to compress. With no loss.

Andrei Georgescu I think he was referring to the fact that biologically produced music (voice, human trying to hit a physical instrument at exactly the right timing and point) contains unintentional variations beyond what the artist wanted. Lossless compression will need to store those details as it guarantees no omissions. However some fans actually enjoy some of those unintended variations for their emotional/human qualities, which makes it harder for lossy compression designers to decide what to throw away. Now if the same artist plays the same music on computerized instruments, uses a digital effect to simulate a chorus of her own twins and uses a single take of the repeated lines, then a lot of those random differences won't be there and thus don't add to the best case compressed size.
