Twenty years ago, most computer centers had a few large computers shared by several hundred users. The "computing environment" was usually a room containing dozens of terminals. All users worked in the same place, with one set of disks, one user account information file, and one view of all resources. Today, local area networks have made terminal rooms much less common. Now, a "computing environment" almost always refers to distributed computing, where users have personal desktop machines, and shared resources are provided by special-purpose systems such as file, computer, and print servers. Each desktop requires redundant configuration files, including user information, network host addresses, and local and shared. | O REILLY Hid Sier .
