hello,
I have ubuntu os installed into my system .I want to make it multiuser in sense that a computer(a terminal without hard disk ) could use the same system .Kindly tell i want to deploy it on my pc.

Thanks in advance

I think your question is unclear. Can you write some more information, what you need to do?

you want to virtualize your copy of ubuntu into different terminals. yes you can, but you need to purchase the device. sample is ncomputing device.

i want to know as to how i can make it multiuser.in the sense that there will be one computer with hard disk and with os installed in it.Then there will be many terminal with cpu but no hardisk and those computer have to use my hardisk .Sp i want to know as to how can i deploy the same

Of course this is possible and often used, but some hard work you must do. You need to install normal system on it, lets call it server, and configure services:
1. ssh - for remote administration (optional, but useful)
2. Xorg, vnc - for remote working on graphical interface
3. nfs - for remote files access
4. tftp, dhcp, http - for network booting
5. you must prepare image of choosed system (for example, Ubuntu has configurable LiveCD) which contain client programs above listed services.

And you need to configure it all.

On client you just only select option in BIOS to boot from network. And client after booting will automatically load system images from server and start working.

Your main goal is "network booting", so read more information about it on Internet.

Have you ever heard of thin client systems ?

You can make it using PXE boot . Just have the nice guide:

Hi,

You want to achieve disk less clients.

Refer this links for configuring the same.But why do you want to go for disk less clients,as now days hdd is very cheap.
