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 e3000. 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 A session 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.
I
IEEE 802.3 A standard for a broadcast local area
network published by the Institute for Electrical and
Electronics Engineers (IEEE). This standard is used
for both the ThinLAN and ThickLAN
implementations of the Local Area Network (LAN).
inetd The Internet server that allows one daemon to
invoke many servers, thus reducing load on the
system. Normally started at system boot time, only
one inetd can run at any given time.
INETDCNF.NET.SYS The configuration file for the
Internet daemon inetd, which determines which
installed Internet Services are available to users.
INETDSEC.NET.SYS The optional security file for
inetd, which lets you control access to individual
services to specific accounts, groups, or users.
internet An aggregation of computer systems and
other types of computing equipment that share
information according to a set of defined
communications protocols. Local networks, such as
all computer systems linked together within a
company, are typically linked to other local networks
via the Internet. Or, individual systems which are
not part of a local network, such as a personal
computer or a standalone business computing
system, can exchange information via the Internet if
they are equipped with the appropriate
communications software and hardware.
Internet Protocol (IP). A set of rules used to route
information between different local networks in an
internetwork, as well as among nodes in the same
local network. The internet protocol corresponds to
layer three, the network layer, of the OSI model. See
also IP address.
IP address Internet Protocol address. An address
used by the Internet Protocol to route information. A
complete IP address comprises a network portion
and a subnet portion to identify a specific network,
and a node portion to identify a node within that
network.
