Is it possible to use 1 CPU with multiple(keyboard,mouse and moniter)

Hello

I am going to open some computer institute. But in the start for saving investment I want to use one cpu machine with five moniter. five keyboard and five mouse.

Will the idea of central computing work here or any device that support this type of network.

My issue is to utilize my single CPU with multiple moniter keyboard and mouse (So that every user with their mouse and moniter virtually assume that they have their own CPU with them) to save hardware cost.


Please guide me in detail because I am also not expert in networking.

Thankyou


Thank You & Best Regards,

First I will say I think that is a bad idea.

Better to just build 5 ultra cheap computers and give the users accounts on the main computer. With Linux you can run a session on the cheap computer that will effectively be run on the main computer. Plus one faulty device won't bring down the whole set.

That will be the easiest way to manage this. If you try to run 5 monitors and mice from a single box you will have a nightmare. Especially considering Linux is just getting good with UI concurrency. It will be MUCH harder learning path to even approach that.

Look into x-term/X11 forwarding and ssh (secure shell).

The original Unix concept was for just such an arrangement - one (mini)computer and multiple terminals. In text mode.

Linux supports that, including the next step up from there (multiple X terminals). You didn't actually say GUI, but that's usually taken for granted these days.

Technically, no problem. I've even done some of that. Realistically, however, the economics are no longer viable in most cases. The ratio of the cost of a CPU system vs. the cost of a terminal - especially an X terminal - is just too low. The only case where it even begins to look attractive is if you have a bunch old old 386's lying around with nothing better to do than be converted into X systems. And the easiest way to turn a 386 into an X terminal is to install Linux (or BSD) on it.

Practically speaking, you're likely to spend more on the electricity than on the hardware over the course of a year or 2.

So good luck if you can find a cheaper way, but don't be surprised if you've bottomed out.
