Software licensing is easier, too, with one server. Security is more easily handled on a thin client, also. Because thin clients do not contain hard drives, they cannot be corrupted by destructive users or viruses. The biggest selling point for thin client technology is cost savings. Thin client units cost less than PCs.
Thin clients are generally more durable and easier to maintain than PCs.
Security is another important consideration. It is easier to secure a server, with all its data, applications, and processing power, than to secure many workstations in the academic environment. Users cannot use floppy discs to move data, so the risk of viruses is reduced. Software applications and upgrades are loaded only once by the Systems Administrator and these are instantly available to all users. The Systems Administrator does not need to track the licenses for software loaded on individual machines.
