I once worked in a red teaching basic computing. The room I worked in
had a facility whereby I could swiitch a device on and all the other
student's computers were disabled and they were forced to watch what
was on my screen. when i switched off the device their computers came
back to life so to speak. i haven't heard of this device since and have
tried in vain to find it on the net. does anyone know which device i'm
referring to and what it is called.
