correct me if im wrong....

client server os... its smthing like having a small or basic minimum power pc... maybe a thinclient... just enough power to run a remote desktop back to a server...

all the programs and processing need will be done in the server itself... therefore u will have easy maintaining client pc as when a pc giv problem just swap with another 1 as there will be no data stored in the pc or thinclient...

data security as there will be no data transfer between server to client. the only data transfer is keyboard/mouse movement plus the screen image only.

my experience on terminal... pls get a super great powerful server..

my current environment...

HP DL380 with QC with 4GB
all for approx 20 users... each user open excel files about 10 files at the same time.

it was all ok... but the most resource eating is microsoft outlook... even with the database stored in other server... damnn....
