device file A file being input to or output from any peripheral device except a disk. HP-UX
allows operations to be performed on the device itself as if it were a file.
device independence A characteristic of the operating system that allows users to selectively redirect input/
output from a program, session, or job irrespective of the nature of the device.
device name See device file.
direct-connect device An asynchronous device that is connected directly to a DTC 16RX through an
RS-232-C or RS-423 cable, with no intervening communications equipment. Also
referred to as a local connection.
DNS (Domain Name System) Server
A system on a network that resolves names into IP addresses, so that connections can
be made using names rather than IP addresses.

DTC Datacommunications and Terminal Controller. The DTC is a hardware device,
configured as a node on a LAN, that enables asynchronous devices to access
HP computers. Terminals can either be directly connected to the DTC, or they can be
remotely connected through modems.
DTC 16RX The HP J2064A product. A routable communications server that enables up to 16
asynchronous connections to HP 3000 Series 900 computers and computer systems
