You might want to know more about PXE boot. That's most likely what is being used in these cases. I only use it to install Windows (and other OSes) on a 1Gbit link and not for everyday booting.

All the computers start up from a shared network. The network contains a .iso of the bootup. The .iso is loaded into RAM which becomes the Operating System.

Actually it boots an image of a hard drive.
The parts of the OS required to run stuff is loaded to the ram and most of the applications is stored on the server afaik.

Also they use Windows since it's what almost all users use. :p

If it's loaded from ISO file, OS will be reinstalled fresh every workstation boot up?

What's in my mind is this... A server with 2 DISK, 1 DISK for the main server and 1 DISK is for all the pc in workstations.

Imagine this as Library computers. You wouldn't want people coming in and deleting files and running off right? You want a fresh start every time.

Hmm something like using deep freeze? every time it restart it's fresh.

Well if you dont know PXE is here according to wikipedia:

Code: (Select All)

In computing, the Preboot eXecution Environment (PXE, sometimes pronounced as pixie[1]) specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP.

The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard. In modern data centers, PXE is the most frequent choice[2] for operating system booting, installation and deployment.

but basically the cilent computer will boot through the server drive . it will save hard drive space and also cost because you only need to buy hard drive for server instead for all the cilent

Yes, when you reboot the computer, everything goes back to the image you used Deep freeze with. Everything stays the same.
