network connection (hence the term
connectionless ), each datagram must
contain all the information required for its
delivery. The protocol associated with
datagram service is UDP, or User
Datagram Protocol. See also datagram,
protocol, and UDP.
DCE Data circuit-terminating equipment.
The interfacing equipment required in
order to interface to data terminal
equipment (DTE) and its transmission
circuit. Synonyms: data communications
equipment, dataset.
domain name A name designated for a
system in ARPANETstandardformat. This
name can be used by other nodes on the
network to access the host for which it is
configured.
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
3000 Series 900 computers. Terminals can
either be directly connected to the DTC, or
they can be remotely connected through a
Packet AssemblerDisassembler (PAD).The
DTC can be configured with DTC/X.25
Network Access cards and DTC/X.25
Network Access software. A DTC/X.25 iX
Network Link consists of two software
modules: the X.25 iX System Access
software (on the host) and the DTC/X.25
Network Access software (on the DTC).
DTC Telnet Access An HP product
providing Telnet connections from HP 9000
and non-HP systems running ARPA
standard Telnet services to the HP 3000.
The solution includes a Telnet Access Card
(TAC) that resides in the DTC 72MX or
DTC 48 and provides protocol conversion
between Telnet and Avesta Flow Control
Protocol (AFCP). Equivalent functionality
is provided by a separate product, the
Telnet Express Box (TEB).
DTE Data Terminal Equipment.
Equipment that converts user information
into data transmission signals or
reconverts received data signals into user
information. Data terminal equipment
operations in conjunction with data
circuit-terminating equipment.
E
environment Asession that is established
on a remote node.
Ethernet A Local Area Network system
that uses baseband transmission at 10
Mbps over coaxial cable. Ethernet is a
trademark of Xerox Corporation.
F
file equation An assignment statement
that is used to associate a file with a
specific device or type of device during
execution of a program.
flow control A means of regulating the
rate at which data transfer takes place
between devices to protect against data
overruns.
FTP File Transfer Protocol. The Internet
Services protocol that facilitates the
transfer of files between systems.
Originally developed by the Advanced
Research Projects Agency (ARPA).
H
host computer A computer on which
network communications software resides,
and which is currently providing a service
to a requesting client.
HOSTS.NET.SYS The host name data
base file which associates Internet
addresses with official host names and
aliases.
