Because it's based on the COSMAC Elf[^] and there alredy have been countless takes on the original design. And the names are just as diverse as the hardware. So what would you call your modernized versions of the Elf?
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

You misunderstand me. I meant that the next version after zwölf should be dreizehn.

But Zwölf is not finished yet and will not be any time soon, if ever. After almost 45 years I'm still not done with the old Elf. Besides that, maybe you understand too well. Elf (as in pointy ears), Zwölf...

The survey question reminded me that I've always wondered about this. Does it use the computer's memory or the existing graphics card memory? Is the computer's graphics card involved in any way? It seems so because on my latest laptop I can really up the resolution of Skyrim, but how in the world does that work? And it seems like this is a ton of data to be transmitting constantly - is it optimized in some way?
When I ask this question on Google, the links I get are really stupid and don't explain any of the technical details that are what I'm interested in. Maybe my Google Fu is not awake this morning yet.

The cheap USB3 version just has your system output an HDMI signal over the USB wires. This needs support on the host system; and probably won't work with a PCIe GPU and USB3 slot on your mobo.
Edit: IIRC this one needs a USB C port in order to use both the normal and inverted pins to have enough high speed IO outputs, and a 3.0 USBA port would still need the below. IIRC This gives the output bandwidth for 1440p60 signalling. 4k60 would require the fastest USB3 mode that can do 20gps (the 10gbps mode is just doing the same use both sets of data pins as HDMI over USBC).
The expensive version that also works on USB2 is from a company called Display Link. I'm not sure if their software captures video being rendered by the onboard GPU and then compresses it to fit in USB2 bandwidth, or if they have a crappy GPU on the other end of the USB cable and just send draw commands over it.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

There are a number of different ways to do it.
I have a couple of modern TV's for example, that have HDMI inputs where there is actually little to no video data sent over the link. Instead, the TV actually includes the GPU, and all that's used on the HDMI connection is a high speed serial bit stream of GPU commands.
Like wise I also have USB3 to HDMI/DVI/VGA adapters that basically have the same GPU inside the adapter, and take a serial bit stream from the USB3 port, in much the same way my TV takes it's GPU input over the HDMI serial link.
Broadcom make a LOT of SOC's that can do this decoding in real time, and many of the devices I open and investigate (esp the older ones) tend to have broadcom chips in them.
In some cases though, yes it is just a straight through high speed serial link, USB3 to HDMI, you tend to be able to spot these ones though, they are generally smaller than the GPU based ones, and they won't work with some makes of monitors (EG: ones that don't have their own on-board GPU)

Marc - your google fu has not failed. Something has happened to google search that has made it useless. Most of the results are ads, companies, etc but no information.

i do not know if my google chop any use, or just ad blocks. Also im plagued with quora results now 
snippet from article
Quote: The USB to HDMI active adapter basically works like an external graphics or video card as an interface between the computer and monitor. Most computers will have a USB 2.0 or 3.0 Type A port. This is the slender rectangular port.

so sounds like for this specific device, driver captures output somehow, transmits to usb, and usb device has converter to hdmi signal. the USb / HDMI devices iv used tend to have a chunky block in them to mean have some kind of processor in them along with with the connectors.
so what doing work, cpu, to capture output, but gpu might still be doing number crunching

You apparently have to register as an HDMI "adopter" at www.hdmi.org to get these specifications. I used DuckDuckGo to find this site.

Call what you will, I'll call it "Nope, no, no, NO, no way, mad, crazy insane, never in a million trillion years".
I've just watched a couple of videos, like this one The worst claustrophobic caving you will ever see. *TRIGGER WARNING - YouTube[^].
I don't flinch when watching horror/slasher movies, but this just creeps me out to the max. I'm still shuddering just at the thought of being underground like that, crawling through spaces barely body width.
I think I'm going to have nightmares for weeks. If I can't drive a car through it, then I'm not going near it.

The task itself is interesting and I would sign up for it if I was fit. The video is boring after a while.

I remember exploring a cave on the hill above our town many years ago. My friend and I (aged about 13) walked in with a torch and a candle. after about half an hour we reached a large hole filled with water, which was passable by walking across a wooden plank. I started across but the plank felt a little unstable so we called it a day and worked our way back out.
At the age of 55, my wife and I went to the Kango caves in South Africa. There was a guided tour through the caves which we joined. It included climbing, sliding and crawling. It was only when we came out at the end that we realised we were about 20 years older than all the other participants.

I've been in public caves such as Carlsbad Caverns, but I have no desire to go spelunking. As for potholing, I try to avoid them as they're heck on wheels and suspensions.

I've been exploring, surveying and mapping caves in Tennessee, Alabama, Georgia, and Kentucky since I was 10 years old. I love the quiet, the beauty, and the thrill of being somewhere no one, or very few, have gone before. Hence my username and avatar. 
Having said that, I don't care for tight squeezes either. When I'm already crawling on my belly and I start to feel the ceiling on my back and I've got more than a few feet to crawl that way, that's where I stop.

I won't even go into Jenolan Caves[^] and you can drive a B Double through them!

I love caves, but only when I can stand (or at least "comfortably" crawl) in them 
Seen some really beautiful sights like that
I read about a guy who got stuck halfway through some cave and upside down and not even the rescue workers could reach him.
From that moment on it was waiting for a slow and agonizing death (about 24 hours of (knowing you're) dying basically).
Sounds like one of the worst ways to go
No way I'm risking that for a bit of a thrill

Sounds like John Jones, they couldn't get him out and just sealed up the entrance.
The next post by BryanFazekas has a link which touches upon his case.
