data transparency
During a session, the access server normally intercepts and interprets switch characters
and
flow control
characters. Users can enable data transparency, causing these
characters to become transparent to the access server. The access server will not
intercept them while they are being exchanged in the user’s current session, such as
during a file transfer or during a block-mode transfer (where the terminal sends a
screen of data to the host application).
DECnet
The DIGITAL networking software that uses the DIGITAL Network Architecture
(DNA) on both
local area networks (LANs)
and
wide area networks (WANs)
.
DECnet node address
A unique numeric identification required for each DECnet node, assigned by the
network manager. The address is in the form
aa.nnnn
, where
aa
is an optional
area
number (from 2 to 63), and
nnnn
is the node address (from 1 to 1023).
DECnet node name
A unique 1-
to 6-character alphanumeric identification (including at least one
alphabetic character) required for each DECnet node assigned by the network
manager.
dedicated service
A
network
resource
to which a
port
is permanently assigned and to which the port is
always connected at login, thus emulating a hardwired connection.
