Connect a second keyboard and monitor to a Windows PC / laptop and let two children study on the computer at the same time?

We know from Unix systems that many terminals are connected to one system. Today's laptops and PCs are fast and clever enough. Why can't you build a second access to the computer with a second monitor and a keyboard? The speed of reaction can't be a problem. In this way, two children could communicate with their school at the same time.

Nowadays it is no longer worthwhile, as the peripherals are usually more expensive than the central processing unit. I think it is still possible with Windows Server 2008 and the following. But as I said: it will probably be more expensive than buying two laptops or two desktop PCs with Windows 10 at the same time.

Because PCs / laptops are not designed for this!

This is only possible with a central terminal server and two thin clients. Without this, it is not possible for two to work on one PC

Remote Desktop can be used on any PC. But it may be that you need a Pro version under Windows.

Otherwise it is simply due to missing drivers / software. The use case where several users sit on a local device is really very rare. I can't think of a really good reason for it. You can also use 2 laptops.

It's about at the same time but not so that both see the same thing:-) what you are describing is more about the fact that one controls the other and wants to show something like that, but not that people work completely independently of each other

You can connect both a monitor (or other output device) and a keyboard to most laptops. That is not an issue

No. With Windows you can also let several users work in parallel on one device, I think. If necessary, stop under Windows Server.

Keyboard and a used monitor - but would be a financial help for everyone who can't afford the 2-computer. Isn't it just a program that one needs, what logic explains to the computer.

Why? You can connect a keyboard via USB and actually every PC has a second monitor output (where else should you connect your projector) Is just a program that should explain to the computer what it should do with the additional signals.

If you think it will work out, then do it?

I'm not aware of a cheap solution with Windows. It is only expensive with a Windows server and 1 client operating system. But I don't think it runs on the same CPU either. If it should be possible, then with so much admin know-how that you would hardly have asked this question if you had known.

To be precise, it works with the server versions. With the normal Home / Prof / Enterprise only one can log in at a time. You also need a second computer for this. So nothing is gained.

You build computers with several CPUs and that should be a serious problem?

You just want a program to make a terminal function available to a second input device and output device.

You can't connect 2 keyboards to one computer and expect that the key presses can be assigned to different tasks. The USB signals are evaluated very deeply in the operating system and are already available in the BIOS.

Yes, two monitors are no problem at all, and neither are two keyboards. However, both keyboards then work in parallel, so it doesn't matter which keyboard you type on. You can't work in pairs like this. The same applies to mice.

Yes that's true. But if you buy 2 screens + 2 keyboards + 2 mice + a device with the appropriate software, you can certainly buy more than 2 cheap laptops for the same money.

Then you would have to put something upstream that tells the computer that the 2nd keyboard is not a keyboard… Hm that wouldn't be difficult.

With Unix and Windows servers you can indeed connect several terminals. A "terminal" is more than just a keyboard, mouse and monitor. It is a stand-alone computer that communicates with the server.

So for your question you would need 3 computers: One server and 2 that work as a terminal.

Connecting two keyboards and mice to one PC does not allow them to be assigned to different applications. This means that the approach with a PC does not work under any circumstances.

Of course, you can build a device that manipulates the USB connection so that it no longer functions as a human interface device. How you then want to turn on any program as keyboard input remains hidden.

If you can do that, the device would be suitable for hacking other people's PCs. So, ask if it's illegal before you start using it.

Not really. It would essentially be a terminal program and a component that does not "mask" the 2nd keyboard as a keyboard connected directly to the computer. (See answer from Gaul question)

How can you hack someone else's PC with it?

It would be a matter of a "Termina program" to insert the 2nd mouse and keyboard in a suitable way under the computer…

It doesn't matter whether this is "supposed" to be a problem or not. PCs running Windows are not intended for this. The provision of a terminal is provided for in the Windows server operating system and therefore it costs thousands of euro in license fees. Maintenance is something you'd better take a few courses for.

As already mentioned, you also need 1 server and 2 client PCs.

You can connect it to a PC and use the user's credentials and record his screen contents. Even possessing such hacking tools can be a criminal offense.

GallierFrage explained that you just need 2 thin clients, i.e. Two small, slim computers (normal PCs also work) that take over the terminal function via the network. The host must then be a Windows server. The license fees for this far exceed the price of 2 mid-range laptops.

This is different under Linux, because the hardware-related drivers can be accessed without any problems. See e.g. https://wiki.ubuntuusers.de/Archiv/Multiseat/
