The archtypal product was the 3Station developed by Bob Metcalfe at 3Com. Another example was the Sun 3/50. Diskless workstations are ideal when many users are running the same application. They are small, quiet, more reliable than products with disks, and help prevent both the theft of data and the introduction of viruses since the software and data available on them is controlled by the network administrator or system administrator.
