I recently observed this strange set of workstation at my workplace where around 30 monitors are installed and it seemed to be running fine.There was no CPU connected to the monitors but there was a modem like thing which has connection to the monitor and in parallel to other PCs adjacent. Later it was realized that a virtual connection has been set up.
From what explanation i received,there was a main Computer with a CPU and server connections. And the required software were installed on that PC which could be accessed by the remaining 30 PCs.
My main question now is how is this connection established.Would it compromise on the performance or speed while the remaining users perform their respective tasks. Also can the processes being executed on the respective PCs be tracked at this main server machine.
