Aha! PC terminology (see what I did there)?
Or even central and satellite monitors. In some systems (old ones at least) the central display was effectively "dumb" - the bedside monitors being the "drivers".
In Ye Olde Days there was no PC at the central station (probably due to the fact that PCs hadn't been invented yet); the central station was really just a monitor (sometimes quite a large one, sometimes a couple or more), a bit of switching and a printer. In fact, in some set-ups the central station was the cheapest part of the system. Happy Days
But yes, I should imagine that modern set-ups are in fact a server and clients (in the computer network senses); a server at the central station (although it could be elsewhere) with client monitors dotted around. Some monitors may be portable, or even hand-held (wireless). That is what made me mention IP addresses previously. Not to mention:- telemetry. All good Biomed Stuff.
PS: I believe that the "master" (cylinder) and "slave" (cylinders) terminology is still used in vehicle braking systems.
